Water Management of Schisandra chinensis Orchard
1. The root distribution of irrigated Schisandra chinensis is shallow, and drought has a great effect on the growth, flowering and fruiting of Schisandra chinensis. There is less rainfall in spring in Northeast China, which is prone to drought, which is extremely disadvantageous to the early growth of Schisandra chinensis. If irrigation can be carried out in time according to climate change and plant water requirement in a year, it will play a significant role in improving the yield and quality of Schisandra chinensis.
Schisandra chinensis is most sensitive to water in the period of germination, rapid shoot growth and rapid expansion of berries. The lack of water in the early stage of growth will result in irregular sprouts, short shoots and leaves, and lower fruit setting rate, which has a serious impact on the yield of the same year. In the initial stage of rapid expansion of berries, the lack of water will often have a negative effect on the continued expansion of berries, resulting in serious fruit drop. Slight water deficiency during fruit ripening could promote berry ripening and improve fruit quality, but severe water deficiency would delay ripening and decrease berry quality.
The irrigation period, times and the amount of irrigation each time are often different due to cultivation methods, soil thickness, 'soil properties, climatic conditions, etc., which should be flexibly controlled according to the specific local conditions. Generally speaking, reference can be made to the following major periods for irrigation:
① was irrigated once after thawing to before sprouting. This irrigation could promote plant sprouting neatly and was beneficial to the rapid growth of new shoots in the early stage.
Irrigation of ② twice before flowering could promote the rapid growth of new shoots and leaves and increase the rate of fruit setting.
③ can be irrigated for 2 or 4 times according to precipitation and soil conditions from flowering to berry coloring. Irrigation during this period is beneficial to berry expansion and improve the quality of flower bud differentiation. As Schisandra chinensis is a traditional Chinese medicine, the water for irrigation should meet the water quality standard for farmland irrigation (well water and Rain Water can be regarded as sanitary and suitable for irrigation).
2. Drainage the northeast provinces are in the rainy season from July to August, and the rain is abundant and concentrated. In the Schisandra chinensis orchard in the mountains, we should do a good job in soil and water conservation and pay attention to drainage. The flat land Schisandra chinensis garden should also arrange the drainage work, so as to avoid the plant damage due to waterlogging or the spread of diseases caused by excessive humidity.
In places with high groundwater level and low-lying terrain, drainage ditches with a depth of about 0.5 to 1.0 meters can be dug every 25 to 50 meters in the park, and the drains in the mountains had better lead to reservoirs (or reservoirs) for irrigation in times of drought.
Seedlings and young trees in the nursery are easy to grow green, so more attention should be paid to drainage.
(4) thinning of sprouting tillers and underground horizontal stems
Schisandra chinensis is a special tree species, the underground transverse stem is an important organ for asexual reproduction, the growth of underground transverse stem is very large every year, and a large number of tillers will occur, which will not only cause greater nutritional competition and waste, but also because its growth momentum is relatively high.
Strong, clinging to the surface of the fence will also cause the deterioration of the lighting conditions of the shelf surface, so the operation of removing underground horizontal stems and sprouting should be carried out every year.
1. Except for the underground transverse stem of Schisandra chinensis, the distribution of underground transverse stem is relatively shallow, which is mainly concentrated in the soil layer 5cm to 15cm below the surface, which is easy to remove. The removal period is the budding stage from defoliation to freezing or after the bleeding stops. When removing the transverse stem, attention should be paid to the protection of the root system because of the shallow root distribution. In addition, because Schisandra chinensis has adventitious roots on the underground stem, it can continue to grow and form new plants after being cut off from the mother, so it must be removed completely from the ground so as not to cause trouble to the future work.
2. Except for sprouting tillers in the annual growing season, the underground stems of Schisandra chinensis will produce a large number of sprouting tillers. The period of removing tillers should be determined according to the specific conditions, so that they can be found and removed at any time, so as to facilitate the normal growth of Schisandra chinensis and facilitate the management of the shelf surface. In the removal of tillering, for the weaker plants, we should pay attention to the selection of exuberant sprouting branches as the preparation of the main vine, not all of them, otherwise it is not conducive to the renewal of the main vine.

Soil Management of Schisandra chinensis Garden
In nature, soil is the basis of plant growth and the source of water and nutrients. If the soil is deep, loose and well ventilated, the microorganisms in the soil are active, which can improve soil fertility, which is beneficial to root growth, enhance metabolism, and play an important role in enhancing tree potential, yield per unit area and fruit quality. Therefore, soil management is an important part of pollution-free standardized cultivation of Schisandra chinensis. The soil management of Schisandra chinensis is based on its growth and development characteristics and nutritional status.

Schisandra chinensis [Schisandrachinensis (Turcz.) Baill.] It belongs to Magnoliaceae and Schisandra chinensis, which is a famous traditional Chinese medicine and is listed as one of the important medicinal materials in the development strategy of northern medicine in Heilongjiang Province. It is mainly distributed in Northeast China, as well as in North China, Hubei, Hunan, Jiangxi and Sichuan. Schisandra chinensis is used in medicine with fruit, the berries are fleshy, spherical and crimson, which can treat lung deficiency, cough and asthma, diarrhea, night sweats and so on. After the national implementation of the natural forest protection project, people's development and utilization of Schisandra chinensis has also caused
