The latest course of fertilization techniques and methods of Schisandra chinensis

Schisandra chinensis is a kind of high-grade traditional Chinese medicine, which is divided into Schisandra chinensis and Schisandra chinensis. Schisandra chinensis is suitable for growing in humus-rich soil with fertile soil, good drainage and slightly acidic soil. At present, it is mainly produced in Heilongjiang, Jilin, Hebei and other places in China. So in order to improve the yield and quality of Schisandra chinensis, and scientific fertilization is the key, let's learn the fertilization methods of Schisandra chinensis.

1. Base fertilizer

Schisandra chinensis has a great demand for nutrients, and it is constantly absorbing nutrients, so we need to apply sufficient base fertilizer when preparing the soil. The base fertilizer is mainly organic fertilizer, combined with nitrogen fertilizer, phosphate fertilizer, potash fertilizer and other chemical fertilizer. At the same time, we also need an appropriate amount of trace elements in the soil to improve the soil structure and make the soil most suitable for planting Schisandra chinensis.

2. Growth fertilizer

Growth fertilizer should be divided into several times, not one-time fertilization. The growth fertilizer should not be too heavy, otherwise it will seriously affect the growth of Schisandra chinensis. The first topdressing of growth fertilizer is about ten days after the planting of Schisandra chinensis, the amount of topdressing should not be too large, usually controlled at about one jin, mainly ammonia and potash fertilizer. The second topdressing was a month later, when it was applied according to the amount of fertilizer needed for 75 jin per mu, mainly phosphate fertilizer, combined with urea and potash fertilizer. The amount of fertilizer applied in the third time should be increased, and the amount of fertilizer per mu is 5,000 jin, mainly rotten farm manure. In the later stage, we also need to apply reasonably according to the growth of Schisandra chinensis.

3. Promoting flower and strong fruit fertilizer

Generally speaking, Schisandra chinensis begins to enter the flowering stage in May every year, and we need to apply fertilizer in advance to promote flowering and prolong the flowering period, so as to improve the fruit setting rate. This is that we mainly spray with foliar fertilizer, that is, boron fertilizer. The second is between June and August, which is the period of fruit growth. We mainly use potash fertilizer as phosphate fertilizer, and we also need to use foliar fertilizer in order to improve the quality of Schisandra chinensis.

4. Periodic fertilizer

Periodic fertilizer is actually a fertilization after the harvest of Schisandra chinensis. Periodic fertilizer is also called winter fertilizer, winter fertilizer, conservation fertilizer, base fertilizer and so on. The main purpose of topdressing periodic fertilizer is to prepare for the yield and quality of the coming year, as well as to apply Schisandra chinensis safely through the winter. Then the periodic fertilizer is mainly organic fertilizer, and appropriate spraying foliar fertilizer, supplement root nutrition, or the use of biological fertilizer, which can not only reduce the cost of planting, but also improve the quality of Schisandra chinensis.

The above are the basic fertilization techniques of Schisandra chinensis. Generally, mastering this fertilization technology will have a good effect on the yield and quality of Schisandra chinensis. This is the end of the editor's sharing today. I hope it can be helpful to everyone.
