Field Management Methods of Fructus Schisandrae Chinensis
(1), rack surface management
In the juvenile stage, the selected main vine should be tied to the bamboo pole in time to promote its upward growth. In principle, the new shoots of the adult tree side vine should not be tied. If there is too long, 8-10 nodes can be left to pick the core. If the side vine (fruit mother branch) is too long or the load is large, necessary binding should be given to avoid breaking the branch.
(2) Intertill weeding
More than 5 times a year, the depth is about 10cm, and the soil in the planting belt is kept loose and free of weeds.
Deep ploughing After fruit harvest, deep ploughing of the whole garden is carried out, with a depth of 20-25cm, and completed before late September.
In annual orchards, short naked crops such as soybeans can be planted between rows. 2 years old orchards to keep clear tillage fallow; before germination, remove the plant base produced last year sprouts.

Asexual Propagation of Schisandra chinensis-semi-lignified Greenwood Cuttage
The semi-lignified shoots of Schisandra chinensis varieties or superior lines were selected as test materials for cutting propagation in the first and middle of June. Generally speaking, it is suitable to collect cuttings before 10:00 in the morning. The length of cuttings is 15 to 20cm, and the thickness should be greater than 0.3cm. The leaves in the middle and upper parts should be retained, and the leaves at the base (scissors) 3cm and 5cm upward should be cut off. The lower cuttings fall on the semi-lignified nodes and the cuttings are inclined. Soak the cuttings in 0.1% carbendazim solution for 1 minute or 2 minutes, shake off the water droplets and then use 1000 mg / kg naphthylacetic acid (NAA) or 100mg / kg ABT.

Chemical weeding techniques in Schisandra chinensis field
In recent years, the production of traditional Chinese medicine in Dandong has developed rapidly, especially the cultivation area of Schisandra chinensis has increased year by year, which has become a new bright spot of economic growth in our region. But the weeds in Schisandra chinensis seedling field and Honda have always been a headache for drug farmers. Traditional manual weeding is laborious and laborious, and the use of herbicides can effectively improve production efficiency, but there are few experiments. We tested the chemical weeding technique in Schisandra chinensis field with large cultivated area and achieved good results. 1. The investigation results of weed species in Schisandra chinensis field showed that Dandong
