What is the method of high yield of Schisandra chinensis in two years?
In the process of cultivation of Schisandra chinensis, a single plant and two strips are generally used. if it is well managed, it can grow full at that time, but most of them are half-frame or more than half-shelf. Now it is best to plant a single plant and a single vine, and the specific method is to keep half a frame in the first year. In that year, the branches can grow 2 meters, the thickness of the main vines can reach more than 0.4 meters, and the yield per mu can reach more than 400 jin in the second year. The second spring at the bottom of the main vine and the underground stem in the selection of reserve vine, the third year double vine fruit. Another method is close planting method, that is, 2200 plants per mu, one 20cm, one bamboo pole in the middle of every two plants, the distance between each plant is still 40cm, and the yield per mu can reach 6-1200 jin in the second year. This planting method has strong high yield and high benefit in the early stage, but the seedling per mu has doubled.

High-yield cultivation measures of Schisandra chinensis
In order to achieve high yield and high efficiency in the artificial cultivation of Schisandra chinensis, we must first grasp three links: first, we must select, purify and improve the varieties; second, we must go through a process of domestication and adaptation; third, strengthen pruning to regulate and control the tree potential, and the three complement each other. As early as 20 years ago, many farmers in our county tried to cultivate Schisandra chinensis, but failed in the end. The improved variety breeding base of Schisandra chinensis in Kuandian County began to carry out experiments in 1985, but it was not successful in the first two times. In 1993, they summed up the reasons for two failures.

Schisandra chinensis can reverse the multidrug resistance of tumor.
The crude extract of Schisandra chinensis and its active component Schisandrin A can reverse multidrug resistance and greatly improve the sensitivity of tumor cells to antineoplastic drugs. The structure of Schisandrin An is different from the known multidrug resistance reversal agents, so it is a kind of Chinese herbal medicine with development prospect. This is a "new discovery" disclosed in his academic report by Liu Gengtao, a researcher at the Institute of Medicine of the Chinese Academy of Medical Sciences and academician of the Chinese Academy of Engineering, at the recent Guangzhou Pharmaceutical 2006 Cross-Strait Pharmacy (Yangcheng) Forum.
