High yield red pearl of Schisandra chinensis
Dai level, Fengcheng, Dandong, introduced 150 seedlings from the Chinese Academy of Agricultural Sciences in October 2000 and cultivated them with exclusive technology for four years. In October 2004, 20 trees producing 5-10 kg fresh fruit were selected from 150 trees. Among them, No. 1 tree is particularly outstanding: strong body, thick green leaves, luxuriant branches, full fruit juice, large leaves, thick leaves, disease resistance, standard tree shape, good appearance, 302 strings of fruit, 33 grams per string, 1.03 grams per grain, 8.5 cm in length and 5 cm in diameter. There are large and small clusters, there is no phenomenon of fruit size, basically neat and consistent, the standard string accounts for 70%, and the yield of fresh fruit per plant is 7.3 kg. At present, among the 4-year-old trees of the same age in the country, the yield per tree is the highest, and it has not yet been found to exceed the yield of tree No. 1.
From September 3 to 12, 2004, Professor Yan Tinglin (13019382804), a famous expert on traditional Chinese medicine in Northeast China of Shenyang Agricultural University, and Yin Chunyi, deputy editor of Liaoning Farmers' Daily, went to the park to carefully inspect and verify the situation. A large number of photos and cameras were taken, and they were highly appraised as mutants. If they can produce high yields for three consecutive years, they can apply to Liaoning Provincial Variety approval Committee for approval.
On September 29, 2004, Liaoning Farmer Daily reported on the topic of "Red Pearl hanging Fruit". On December 21, the Agricultural Economic Information column of Dandong Daily reported that the yield of "Red Pearl" was twice that of common varieties.
In 2004, Secretary Lu of Fengcheng Vocational High School (0415-6810956), Ms. Yang of Xiaomiaogou, Zhongxing Village (0415-8230615), and Yu Longjun of Dongtang Primary School introduced 700 trees from us in October and planted them in autumn. Form a large number of flower buds, see the fruit in 2006, you can consult.

Construction and Seedling selection of High-yield Schisandra chinensis Orchard
Topographic conditions: different topography has a great influence on the cultivation of Schisandra chinensis. Under natural conditions, Schisandra chinensis is mainly distributed on the forest edge and sparse woodland with shade in mountainous areas. it grows naturally, the yield is very low, and it is artificially cultivated, which has been proved by observation and practice for 5 years. The whole day light in more than 10 hours, a wide field of vision, no major obstacles around, ventilation and light, water, drainage, soil layer of 50 cm is the best place. Water source conditions: Schisandra chinensis is more drought-tolerant, in order to get higher yield and plant growth is good, to strengthen the growth of fast cells.

Control of root rot of Schisandra chinensis
Root rot of Schisandra chinensis, commonly known as rotten ankle disease and choking disease, is one of the main diseases in Schisandra cultivation. At present, the incidence area is more common and the harm is more serious. The disease usually occurs from May to early August. At the beginning of the disease, the epidermis at the junction of the root and the ground (root neck) blackened, further cortical decay, shedding, forming a ring, the leaves wilted, and the whole plant died a few days later. The cause of the disease was related to physiological diseases. The ground changes violently during the day and night in early spring and late autumn, the temperature difference is large, the tissue at the root and neck is tender, the disease resistance is decreased, and the cortex feels frozen.
