Orchid cultivation techniques.
Milan has a strong tolerance for shading, but it is not tolerant of long shading. Especially when potted Milan is in full bloom, it can't be kept indoors for a long time. When flowering, it can be moved outdoors after 4 pm and indoors before 9 am, so that it can receive sunlight and accumulate nutrients for sprouting new branches and flowers. When you are indoors in winter, you should also receive as much light as possible.
Although Milan's requirements for soil are not strict, sandy loam rich in humus, fertile and slightly acidic is suitable. When potting soil is prepared, it is prepared by mixing 2 parts of peat soil, 1 part of Gaza, or 2 parts of fertile garden soil and 2 parts of compost soil and 1 part of Gaza.
When the seedlings grow to a height of 20 cm ~ 25 cm, they can be cored, which can promote the lateral branches to form a crown as soon as possible, and at the same time control the height of the plants and increase the amount of flowers.
When potted in Milan, we should ensure good drainage and moisture according to the dry and wet climate. To keep the soil moist, you can't have too much water for a long time. Maintaining a high air humidity is conducive to the growth of Milan. In the drought and vigorous growth period, it is best to spray water on the leaves 1 ~ 2 times a day.
Milan is lush with branches and leaves, and new branches sprout constantly during the growing period to form spikes, which need sufficient fertilizer. Insufficient fertility will obviously reduce the amount of flowers. To this end, after the spring begins to grow, topdressing should be done in time. It is best to use rotten cake fertilizer or sesame sauce residue water for topdressing. Milan can't stand thick fertilizer, so it is necessary to master the principle of applying thin fertilizer frequently, especially when topdressing begins in spring. Top dressing every 7 ~ 10 days, and appropriate amount of calcium superphosphate should be added to the fertilizer water.
When it is hot in summer, Milan should be placed in a cool place, which can be placed on the edge of the shade shed, so that it will not be exposed to strong light and get more sunshine. Because too strong direct light will inhibit the growth and development of Milan, while too shady will easily cause Milan to grow white, grow weak and reduce the amount of flowers.
According to the temperature requirements of Milan, potted Milan can not be moved outdoors until after Grain Rain, and it should be moved indoors for the winter before the first frost in autumn. It is advisable to keep the room temperature at 10C ~ 12C during overwintering. If the room temperature is too high, it will easily lead to continuous growth, which is not conducive to the growth and development of the next year. However, if the temperature is too low, it is easy to cause freezing injury when it drops below 5℃. Milan overwinters indoors, and its leaves are easy to get gray, which affects its normal photosynthesis, so it should be washed every once in a while.
Plastic surgery should start from the seedlings, and a trunk with a height of 1.5 cm ~ 20 cm should be left, and the main branches should not be clustered off the ground. Because Milan draws flowers in the axils of new leaves, it is generally not trimmed. In order to control the tree shape and add new branches, the core can be picked before the new branches grow, or pruned in combination with cutting.
Ways to make orchids bloom every day
Need nutrition
Orchids want to bloom every day, the first choice is to accumulate nutrients. Under normal circumstances, plants will need to rest for a while before they bloom again, but if orchids can bloom every day, the accumulation of nutrients is essential. The accumulation of nutrients is that light, water and fertilizer must keep up first. With sufficient light, photosynthesis will be good and nutrients will accumulate to some extent. Appropriate amount of water and fertilizer, be careful not to be too much or too little, so that plants can accumulate nutrients.
Need pruning
In addition to cultivating and accumulating nutrients, it is also necessary to prune orchids properly, that is, sparse buds, to reduce the nutrient consumption of orchids to a certain extent, so that flowers can bloom normally.
In spring, smiling faces are in bud, so it's time to relax them. Remove the buds from one or two branches first, and then sparse the buds from one or two branches in a few days. Do this several times in a row until six or seven times, when the number of branches that have been thinned has reached 60%? 70%. After that, when the flowers bloom again, the branches on the orchid plants can open in turn.
At this time, the flowering mechanism of Michelia is that the branches without sparse buds bloom first, and after about 10 days, the branches with sparse buds bloom for the first time, and then the branches with sparse buds bloom in turn. Basically, for a long time, Milanhua can let you enjoy beautiful flowers every day.
Note that plants should be sparse to grow vigorously.
Morphological characteristics and varieties of Michelia indica
Evergreen shrubs or small trees can be as high as 5 meters in origin, and potted plants are shrub-like, but the height is only 1 meter. Branches are many, the crown is neat, and the tops of branchlets are often covered with small brown star-shaped scales, which will fall off immediately after maturity. Odd pinnate compound leaves, alternate, with extremely narrow wings on the petiole, each compound leaf has 3 ~ 7 obovate leaflets, and the surface of the whole leaf is dark green and shiny. Small panicle, inserted in leaf axils at the end of the tree. The flowers are very small, about 2 mm in diameter, yellow and fragrant. The flowering period is very long, and it is the most prosperous in summer and autumn. As an ornamental plant, there are Taiwan Province pineapples, which have larger leaves and fewer flowers. Its flowers often bloom with the growth of new branches, mainly distributed in miscellaneous trees along the coast of Taiwan Province Province, so it is also called Milan, Taiwan Province Province.
Ecological habits of Milan orchids
Milan is native to southern China and Southeast Asia. It needs warm, humid, semi-cloudy and semi-sunny environmental conditions, and has strong shade tolerance, so it is suitable for growing in the sunshine with high humidity in the south. It is very sensitive to low temperature. If the temperature is below zero for a short time, the whole plant will die. When the temperature reaches 16℃, the plant can grow new branches, but it grows slowly and cannot form spikes. When the temperature is above 25℃, it grows vigorously, and the axillary buds at the top of the new branches are pregnant with flowers. Therefore, potted plants can only be planted in other areas except South China. Be sure to move indoors after winter to prevent freezing and keep warm, otherwise it will easily freeze to death. In an environment that does not tolerate drought and likes humidity, leaves will wither and fall off immediately after drought, and roots will die. Fertile and loose neutral or acidic soil is needed.
