Field Fertilization Management of Schizandra chinensis
Schisandra chinensis is a medicinal plant with high economic value. at present, Schisandra chinensis is mainly sold in the wild, and the number of artificial cultivation is very small. at the same time, the market demand of Schisandra chinensis is very large, and the price is relatively stable. Collecting wild Schisandra chinensis is far from being able to meet the market demand, so the artificial cultivation of Schisandra chinensis is being developed in many areas.
The cultivation of Schisandra chinensis is different from the general field crops, there are relatively strict requirements on the use of fertilizer. Schisandra chinensis soil should be kept moist after transplanting and should be irrigated in time during drought and once a year before freezing to facilitate overwintering. It is necessary to apply mature organic farm manure once before freezing in autumn (500ml 700 kg farm manure per mu, ripened by Gymboree microbial starter, and then mixed with about 20 kg Gymboree microbial fertilizer). This saves a lot of cost than applying 20003000 kg farm manure per mu, but it is far better than applying farm manure alone. Quick-acting fertilizer is applied in mid-May and mid-July every year. Ditch application and irrigation were used.
The fruits of Schisandra chinensis cultivated by the above methods are large and uniform, the yield is obviously increased, the quality is improved, and the plant disease resistance is enhanced (resistance to leaf blight, root rot and fruit rot). And greatly reduced the cost of planting, farmers got the real benefits.

The secret of high yield in Schisandra chinensis cultivation
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 two

Difficulties and Countermeasures in the cultivation of Schisandra chinensis
Artificial cultivation of Schisandra chinensis instead of wild resources has been the inevitable trend of the development of Schisandra chinensis industry. There are also many difficulties in the production process of artificial cultivation of Schisandra chinensis, which seriously hinders the development of Schisandra chinensis production to intensive, large-scale and industrialization. it is also the fundamental reason for the lack of large-scale successful experience in the artificial cultivation of Schisandra chinensis. Harm to diseases and insect pests, pesticide residues and drift. The general countermeasure is to adhere to the three principles of prevention, solution and treatment. Prevention: in the process of cultivation of Schisandra chinensis, we should adhere to the policy of prevention over control.
