What kind of fertilizer should be applied during the growing period of orchids?

Orchids in a year's growth period, the fertilizers needed are: 1, Su fertilizer, is to break dormancy, promote early germination, in order to win a longer growth period. When the temperature is more than 15c during the day and not less than 5c at night, it is better to spray inorganic fertilizer (such as urea, potassium dihydrogen phosphate) and biological fertilizer on the leaf. 2. Sprouting fertilizer is used to promote early sprouting, multiple sprouting and win effective buds in early autumn. 7Murray can be applied in 10 days after applying Su fertilizer. 3. Root-promoting fertilizer. When the leaf buds protrude around the basin 3cm, there will be a pause growth period. At this time, new roots will gradually grow and enter the period of vegetative and reproductive growth. At this time, more nitrogen, phosphorus and potassium elements are needed to promote the rapid growth of new roots. 4. Promoting fertilizer is to meet the rapid development, rapid growth and rapid maturity of new buds of orchid plants. And can sprout the second time in late summer and early autumn, in order to win the need of the second crop bud to grow early and mature early, it is the one that applies fertilizer for the longest time and the most times in a year. It is better to use organic fertilizer, inorganic fertilizer and biological bacterial fertilizer alternately, and to apply root fertilizer and foliar fertilizer alternately. 5. Flower aid fertilizer is used to promote the development and growth of flower buds to achieve the purpose of many flowers, large flowers, colorful and fragrant. 6. cold resistant fertilizer, stop applying nitrogen fertilizer 30 days before the orchid plant overwintering, apply more phosphorus and potassium fertilizer to survive the winter, because phosphorus can reduce the freezing point of plant cells, potassium can increase plant cellulose. Stem and leaf cortex is tough, choose potassium dihydrogen phosphate root watering or leaf application. According to Mr. Shen Yuanru: after the Magnolia leaves the house in early spring, it will be fertilized twice before and after the Qingming Festival, each time half a month apart. During the germination of young buds and new roots, more nutrients need to be applied with strong grass fertilizer; seed grass grows very fast during the plum rain, so it is chosen to fertilize twice in sunny days; when Lesser Heat is thin and thin, light fertilizer is applied once; from White Dew to the Autumn Equinox, light fertilizer is applied for the last time; if there is an autumn stem after Cold Dew, light fertilizer can be applied again. Fourth, the basic methods of fertilizing orchids.

There are two basic methods of fertilization: base fertilizer and topdressing. The fertilizer that is directly added to the plant material is called base fertilizer. Because it is difficult to master adding fertilizer to plant materials, and it is easy to breed diseases and insect pests, and it is also easy to burn roots and injure orchids, so the general orchid farmers have stopped picking in recent years.
