If there is no watering for a long time, the water absorption capacity of the substrate is small. Just like the towel that is already very dry, it needs to soak in the water for a while to get wet. It needs to water the basin for many times. Don't water too much, and don't pour too much water to prevent poor drainage and too wet moss in the basin, otherwise it will also cause bud falling, flower falling or root rotting. At present, the commonly used substrates are moss, bark of pine and cypress, vermiculite, ceramsite, coconut shell powder, etc.
The optimum temperature for Phalaenopsis is 25~28 ℃ in the daytime and 18~20 ℃ at night. The growth will stop when the temperature is below 10~15 ℃ for a long time. Therefore, when planting in northern areas, indoor heating is required in winter, and cold waves should be prevented in spring and autumn(nursery plant pots wholesale). Although Phalaenopsis likes temperature, it will enter semi dormancy when it is higher than 32 ℃, which will affect the subsequent flower bud differentiation. Therefore, if the temperature is too high in summer, measures such as ventilation and temperature regulation should also be taken.
Air humidity is the hardest to reach in a family. Phalaenopsis requires a relative humidity of 70%~80%. It is difficult to achieve such a high humidity only by spraying water. The cultivation method is to squeeze out excess water after soaking the cultivation substrate, then loosely wrap the root of the orchid seedling, put it into a basin or a hanging wooden frame, or bind it to a board or wood segment. Home raised Phalaenopsis mainly focuses on temperature, humidity and light.
Therefore, the method of covering it with a transparent plastic film bag and spraying water inside the cover is adopted to create a local small environment. The watering of phalaenopsis is different according to the substrate, temperature and season. Generally, the substrate can be kept in a moist and non dripping state. Watering requires that the water temperature is close to the ambient temperature, and excessive temperature difference will cause root rot. There is no special requirement for water quality, rainwater, tap water and cold boiled water can be used.
In order to add beauty, most florists put several trees together in porcelain pots when selling them. If the fertilizer is not enough, it is easy to fall from the bottom to the top, and the big to small flower buds gradually fall down, and can not open flowers(wholesale seed starting supplies). The rotting root of Phalaenopsis in winter is closely related to the excessive water spraying on the plant, which results in more water in the leaf axils at night, and the excessive humidity of the cultivation substrate. Phalaenopsis is native to tropical Asia, and its habit is warm and cold.
The selection of potted flowers of Phalaenopsis should first depend on the plants. The plants are sturdy, with more than 5 leaves, short, round and neat leaves without yellow leaves and black spots. Those with thick, green, oily and shiny leaves are better than those with thin, thin, yellow or black spots. At the same time, the air root should be strong and thick. It prefers shading and sparse shading conditions. Even in the winter with mild light, 20%~30% of the light should be shielded.
On the flower type, the whole flower is oval (the so-called plastic flower). The poorer varieties have narrower petals with gaps between them, which is called non reshaping flowers. As for the design and color, it varies from person to person. Generally, the prevalence of red, pink, golden yellow or orange is higher than that of white, brown and green in China, but the color of origin has an upward trend in recent years. At ordinary times, the pot soil shall be kept slightly wet, and it shall not be too wet.
If rotting roots are found, the rotting and necrotic roots shall be removed and re potted. Basin soil can be mountain mud or rotten leaf soil, mixed with a small amount of bark blocks or crushed stone particles, or loose hairy soil, mixed with a small amount of moss, ceramsite, coarse sand, etc. as a medium. The basin should have large holes at the bottom and small holes around the basin wall(black plastic plant pots wholesale). When planting on the basin, the bottom of the basin should be thicker to facilitate ventilation, drainage and prevent root rot.
Such as the balcony or under the shade of trees, the ambient humidity should be higher. The high temperature and muggy heat in the summer evening in the south are bad for the growth of Phalaenopsis, the plant growth is weakened, and fertilization is bad for the plant, so it is better to stop fertilization for a period of time. Most of the Phalaenopsis orchids supplied to the Shanghai market during the Spring Festival come from Taiwan, Yunnan and other places. The temperature in these places is higher than that in Shanghai. The flowering Phalaenopsis orchids are bred under high temperature or high humidity equipment conditions.
It is a delicate job to conserve phalaenopsis and make it blossom more. After the flower bud is formed, the temperature at night can be kept between 18~20 ℃. After 3~4 months, it can bloom. The time for turning basin and soil replacement should be generally between April and May (the average temperature is about 15 ℃). After turning over the basin and changing soil, it is not necessary to water immediately, but can be watered every other day. Secondly, after changing pots and soil, potted plants should be placed in semi shade ventilated or ventilated places.
The new plants of Phalaenopsis need to be cultivated for 3 years before they can form flower buds and produce beautiful flowers. The flower bud differentiation of Phalaenopsis is mainly affected by temperature, which requires both a certain annual accumulated temperature and a short period of low temperature treatment(bonsai pots wholesale). In autumn, the low temperature of 15~18 ℃ in the evening is the condition to ensure the flower bud differentiation. The flower seedlings were treated with low temperature for 18 hours every day, and many flower buds could be formed after continuous treatment for one and a half months.
Phalaenopsis has a long flowering period. If the pedicels are cut as cut flowers in the early stage, they can bloom for the second time that year. The flowering time of Phalaenopsis varies with varieties. Generally, each pedicel can grow more than ten flowers, which will open from bottom to top. One flower can open for more than one month. In order to promote its flowering, some liquid fertilizer can be sprayed on the leaf surface and root during the growing season. Fertilization is generally applied once every 3-4 weeks in spring.
Phalaenopsis grows vigorously in summer. Apply solid organic fertilizer once on the basin surface, and then apply liquid fertilizer once a week. After the autumn weather is cool, it gradually decreases, and the fertilizer can be stopped by the end of October. Watering shall be based on the principle of "basin soil is wet without ponding", and the substrate shall be kept wet at ordinary times, while making the root have good air permeability. In humid environment, water should be sprayed on the leaf surface and the surrounding environment to maintain a high relative humidity.
The liquid fertilizer with high phosphorus and potassium content shall be used as the main fertilizer, which shall be applied less and lightly each time(best 1020 trays). It likes semi shade environment with high temperature, high humidity and good ventilation. It shall not be resistant to waterlogging and direct sunlight, and the wintering temperature shall not be lower than 15 ℃. Phalaenopsis can be produced every year, but the sales season is mainly concentrated in the Spring Festival, New Year's Day, National Day and Mid Autumn Festival. Therefore, it is necessary to make it available in the best sales season by means of flowering period control technology.
After that, keep the temperature at 18~20 ℃, and after about 3 months, they can bloom in the Spring Festival. After the flower bud grows out, it shall be fixed on the bracket, and fixed on the bracket section by section as the flower stem grows upwards. Supporting facilities are required for flowering period regulation. Flat multi span greenhouses should be equipped with shading, heating, cooling, semi-automatic ventilation devices and other equipment. If conditions permit, elevated greenhouses can be built in areas above 900 meters above sea level.
Flowers that come into the market around the Mid Autumn Festival should be controlled in the alpine greenhouse for flower bud differentiation. Under the alpine cultivation conditions, from April to May, they mainly promote nutrient growth, accelerate plant growth and development, and reach the physiological maturity stage in the first ten days of June to ensure the flowering after August 25. In the aspect of inflorescence, it is sturdy and upright, 3~4 times as long as the leaves, and has more than 9 flowers. It is better to have 1~3 flowers and 8~10 buds in bud.
The flower bud differentiation of the evening flower can be controlled in the alpine or flat greenhouse. The flowering period starts from the middle of December to the late February of the next year, and the flower bud differentiation starts from the early September to the early October. Phalaenopsis requires a little more fertilizer than ordinary orchids, but a small amount of fertilizer is needed many times(20 gallon grow bags). The new plants of Phalaenopsis need to be cultivated for 3 years before they can form flower buds and produce beautiful flowers. Stop fertilization when flowering, and apply fertilizer once every 10 days after flowering.
The flower bud differentiation of Phalaenopsis is mainly affected by temperature, which requires both a certain annual accumulated temperature and a short period of low temperature treatment. In autumn, the low temperature of 15-18 ℃ in the evening is the condition to ensure the flower bud differentiation. The flower seedlings were treated with low temperature for 18 hours every day, and many flower buds could be formed after continuous treatment for one and a half months. The alpine base and the flat base are used together to ensure the smooth implementation of flowering regulation.
People who grow phalaenopsis for the first time often prefer to buy phalaenopsis planted on a plank (that is, with a snake plank). Perhaps the plank planted phalaenopsis is really beautiful, but unless there are perfect equipment and careful care, it is not easy to grow and blossom well. For the mini rare varieties, those with novel flower color and shape, many flowers, double stems or pedicels with many branches, and the best flowers can also give out fragrance are high-quality varieties.
After high temperature in summer, when the night temperature drops below 18 ℃, flower buds can be formed in about one and a half months(1.5 gallon nursery pots). After the flower bud is formed, the temperature at night can be kept between 18 and 20 ℃. After 3-4 months, it can blossom. First cut off the flower stems above the base, and then remove them from the pot (that is, pour the phalaenopsis out of the original pot). If the root system is intact after removing the pot, just add some moss and other media in the large pot.
When purchasing phalaenopsis orchids, first look at the wide and healthy leaves. They are smooth and bright in appearance, without any spot marks left by pests and diseases. The number of leaves should not be less than 4, preferably 5 to 6. It is normal for each leaf to grow larger from bottom to top. If the leaves become fewer and fewer from bottom to top, it must be a degraded plant with problems. It is likely that the plant will not grow or will not bloom.
In addition, if too much lichen appears in the cultivation medium in the basin, it means that the medium has been rancid, or more than half of the root system in the basin has been rotten, and the plant will gradually wither, so it should be noted when purchasing. If the number of flowers is less than 5, it is not good if the flowers have been fully opened or are still outside the bud stage. The size of flowers should depend on different varieties. Generally, high-quality varieties have broad petals, a sense of carpet, and bright colors.
Phalaenopsis has a long flowering period(24 cell seed tray). If the pedicels are cut as cut flowers in the early stage, they can bloom for the second time that year. The flowering time of Phalaenopsis varies with varieties. Generally, each pedicel can grow more than ten flowers, which will open from bottom to top. One flower can open for more than one month. In order to promote its flowering, some liquid fertilizer can be sprayed on the leaf surface and root during the growing season. Continue shading to cover 50% of the light.
Apply a small amount of fertilizer in spring, and stop applying fertilizer during flowering; Liquid fertilizer once a week after flowering (1000~2000 times); After new leaves appear, a small amount of solid farm manure can be applied to the basin surface; It takes one month to apply some thin liquid fertilizer after changing the basin; Apply liquid fertilizer continuously once a week in summer, and stop applying fertilizer in high temperature and stuffy heat; Start and stop fertilization at the end of October; Do not fertilize in winter. Applying nitrogenous fertilizer during the growth period; Fertilizers with high proportion of potassium and phosphorus shall be applied during flower bud formation and flowering.
It is necessary to observe whether the root system is plump and spreading vigorously. The unsound root system is often the main reason for the decline of orchids, so it is better to choose the one with strong root system. Long time exposure to 15 ℃ is likely to make the old leaves yellow and fall off, or even suffer from cold damage and death. The temperature shall be kept at 15-20 ℃ in winter. A plastic bag can be placed on the outer cover of the pot plant, and a hot water bag can be placed beside the flower plant as a heat source to ensure safe overwintering.
A slightly overcast environment is required at seedling stage, and sufficient sunshine should be received at flowering stage. Watering varies according to growth and environmental conditions. Watering should be less during dormancy after flowering. When the temperature is below 15 ℃, watering should be strictly controlled. Low temperature and high humidity often lead to root rot. It is not suitable to spray leaf water at low temperature(15 gallon fabric pots). The water spraying during flowering shall be prevented from spraying water on the flowers, otherwise the petals will be stained and the view will be affected.
Fertilization should be stopped at flowering stage, otherwise, buds and flowers will fall. When most flower buds open, they can be cut from the third section or above of the stem as cut flowers, or cut off the remaining flowers after the flower has withered to reduce the consumption of nutrients. If properly maintained, flowers can bloom again after 2-3 months. Some varieties can sprout and root on the pedicels to produce seed plants, which can be cut and planted. The bottom of the basin is put up a little with bricks and other things to facilitate the root system in the basin to breathe.
The upper part of the plant with aerial roots can be cut off and planted separately for the grown plant, and new buds can grow at the base of the cut stems. When the new shoots grow up, they can be planted separately. It takes about 2 years for young plants to bloom. As an epiphyte, the potted substrate should be made of moss, bark pieces, fern roots and other materials. Scattered light shall cover 50% of the light. Avoid overcast, when the light is insufficient, the plant grows tensely and is easy to induce diseases and pests.
But don't spend too much time in the shade(round pot carrying trays). Not only will the leaves become narrower and thinner, but also the scape of flowers will become longer and thinner and the buds will become fewer. With the decrease of temperature, water spraying will be gradually reduced, and leaf water will be sprayed frequently. Water spraying will be stopped when the temperature is lower than 15 ℃. Phosphorus and potassium fertilizer should be applied once every 10~15 days to breed flower buds and improve the cold resistance of plants. The medium for cultivating phalaenopsis in southern China generally does not use soil, but mostly moss.
At the same time, one or two years after the plate planting of Phalaenopsis, the snakewood is easy to become rancid and susceptible to powdery mildew. In addition to root drying and other factors, the plant will decline or die after half a year. In this way, it is easy to attack beginners' interest in learning. In spring, when the flower buds and leaf buds of Gardenia jasminoides jasminoides Ellis have not yet germinated (March in the south, April in the north), the work of transplanting and planting and pot changing shall be carried out. Fertilization shall be stopped in winter.
Gardenia planted in pots for 2 to 3 years, or when the root of the gardenia protrudes from the drain hole at the bottom of the pot, the pot should be changed. When changing the pot, the pot soil shall be mixed with horse dung, garden soil and river sand at 4:4:2, and a spoonful of alum or sulfur powder shall be added. 25g of hoof pieces or broken bones, rotten soybean cakes and chicken manure shall be used as the base fertilizer. Those who are transplanted into the ground should also be given sufficient base fertilizer. Water thoroughly to create a sheltered and half shady environment.
In case of strong wind, windproof measures shall be taken when gardenia buds are sprouting(7 gallon fabric pot). Water gardenias all the year round, preferably with rainwater and fermented rice washing water. However, spray water on the blade surface frequently to prevent dust from contaminating the blade surface. In winter, it should be placed in a sunny place, and the room temperature above 5 ℃ can be safely overwintering. Gardenia jasminoides is a trifurcate branch, which is prone to branch disorder and affect the tree shape. The overlapping branches shall be pruned in time to make them dense and appropriate in length.
