Key points of wild home management technology of Schisandra chinensis
There are still many wild natural associations of Schisandra chinensis in Northeast and Northwest China. Home management of these wild Schisandra chinensis can obviously increase the yield and quickly receive economic benefits. The main technical points of manual management of wild Schisandra chinensis are introduced below. 1. Clear forest and flat stubble. Qinglin is to clean up the plants that compete with Schisandra for water, fertilizer and glory, including trees and weeds that hinder the growth and development of Schisandra chinensis, so as to ensure ventilation and light transmission. Clean it up every spring. Flat stubble is the growth of new young branches after clearing the forest, especially a large number of tillers around the plant of Schisandra chinensis.

Propagation method of Panax notoginseng
[propagation method] Cuttage propagation is commonly used. The long stem segment of lOcm was selected in spring and autumn, and one or two leaves were inserted into the mixed medium of peat and sand. Put the countable branches in a pot and water them for the first time. Cover them with plastic film and place them in bright light, then spray fog on the leaves once or twice a day according to the dry and wet conditions. it is easy to rot if it is too wet, and it will take root for 3 weeks. Can also use water culture method, to ensure that the water temperature is higher than the air temperature, a few weeks later can take root. [cultivation management] adequate light is required all year round, but sun should be avoided in summer.

Prevention and Control of Diseases and insect pests of Panax Notoginseng
1. The disease 1.1 Black spot mostly occurred in the high temperature and humid season from June to July, which caused the plant to break and die. The prevention and control method is to adjust the transmittance of the shade to less than 20%, and spray with 1.5% more than 150 times of antimycin or 700% chlorothalonil wettable powder 600 times 800 times. 1.2 Blight is a destructive disease in the seedling stage of Panax notoginseng. Most of them occur from June to July, harming leaves and petioles. The prevention and control method is to strengthen the field management, reduce the temperature and humidity, remove the remains in time, burn them centrally, and spray them with 65% Dysen zinc wettable powder 500 times.

Leaf rot of medicinal plant Panax notoginseng
Symptoms can affect all aerial organs except the roots. The most typical symptom is to cause black fusiform lesions on the top of petioles. When the temperature is high, they quickly circle around the petioles and quickly expand to the base of the leaflets, forming pale black water-soaked lesions on the leaves with irregular edges. The diseased part of the petiole softens quickly, causing the upper leaflet to droop (commonly known as "twisted footwall"). In the disease often visible yellow with pink mold, that is, the fruiting body of the pathogen. When it damages the middle part of the leaf, it forms black irregular spots with irregular edges.

Root knot nematode disease of medicinal plant Panax notoginseng
After the root of Panax notoginseng was invaded by nematodes, the cells of the roots were stimulated by nematodes, the nodule worms of different sizes were produced, the main roots or lateral roots could be distorted and formed tumors, the small 1-2mm and the large ones could turn the whole root into a tumor, and the branches and leaves of the plant turned yellow or fell off after a long time of infection.

Anthracnose of Panax notoginseng (Panax notoginseng)
Symptoms can occur in both seedling stage and adult stage, and the disease in seedling stage can cause sudden collapse or top withering. The disease in the adult stage is mainly harmful to leaves, petioles, stems, flowers and fruits. Leaves infected with primary round or nearly round yellow-brown disease spots, obvious reddish brown edge, easy to rupture and perforation in the later stage. The petiole and stem are infected with fusiform yellow-brown sunken spots, causing the petiole to bend or the stem to twist. Damage to the stem base causes adult plant lodging or rhizome rot. The phenomenon of dried flower seeds appeared when pedicel and disk were infected. The fruit is also infected with nearly round yellow sunken spots, causing the fruit to turn brown and rot.

The main results are as follows: (1) when the prop seedling is 30cm high, build a frame in time to make it climb, and at the same time, pick the heart to promote the germination of lateral buds. (2) in open field cultivation, shading net should be used to shade in summer, which can inhibit flower bud differentiation, make plant continue vegetative growth, inhibit summer flowering, achieve the purpose of producing leaves all year round and increase yield. (3) Fertilizer and water management Panax notoginseng has strong growth potential and large water demand, although it is resistant to drought, it needs frequent watering for its leaves to grow hypertrophy and high yield, and compound fertilizer is applied after each leaf harvest.
