Detailed Explanation of Key Technical Points for Chemical Weed Control in Schisandra Fields
In recent years, the production of Chinese medicinal materials in the Dandong area has developed rapidly, especially the cultivation area of Schisandra has increased year by year, becoming a new highlight of economic growth in our region. However, weeds in Schisandra seedling fields and main fields have always been a major headache for medicinal growers. Traditional manual weeding is labor-intensive and time-consuming, and using herbicides can effectively improve production efficiency, but there have been few trials. We conducted trials on chemical weed control technology in Schisandra fields with relatively large cultivation areas and achieved good results. 1. Survey results of weed species in Schisandra fields show that in Dandong

Detailed Explanation of Key Techniques for Direct Seeding and Seedling Cultivation of Schisandra chinensis in Open Fields
Select a sunny plot with loose soil, flat terrain, moist soil and no water accumulation, and make a low bed 1.2---1.4m wide, 10m long, with a level surface. Sowing uses the drill method. Before the autumn freeze, open shallow furrows 2-3cm deep on the prepared seedbed at a row spacing of 15cm, sow 100g of seeds per bed, cover with soil 3---4cm thick, water thoroughly, press down lightly, then cover with 10cm of leaves or a layer of rice straw to maintain moisture and protect against cold, and remove it when the seedlings emerge. To prevent damping-off and other soil-borne diseases,

Detailed Guide to Herbicide Application Techniques in Licorice Fields (Part Two)
Weeds can severely affect the yield and quality of licorice, competing with licorice for sunlight, water and nutrients. Some weeds are also intermediate hosts for licorice crop pests and diseases, helping pests and diseases spread and transmit. Especially for artificially cultivated licorice at the seedling stage, if weeds are not removed in time, a large number of seedlings will die, or even the entire crop will be destroyed. Now, in addition to manual weeding, chemical herbicides are often used for weed control. In our county, the following 3 chemical herbicides are currently promoted for artificially cultivated licorice: acetochlor, pendimethalin, and doucaote. Practice has proved that using chemical herbicides for weed control is the guarantee

Pest Control Methods and Key Technical Points for Panax notoginseng Seedling Fields
When aphids and scale insects cause damage, spray 50% phoxim emulsifiable concentrate at 1000 times dilution or 40% dimethoate emulsion at 1000 times dilution for control. In plots with a large number of white grubs and cutworms, apply 50-75 g of 90% trichlorfon crystals per mu mixed with 20 kg of fine soil and broadcast, or mix with 50 kg of chopped fresh vegetable leaves and broadcast in the evening. For rodents damaging Panax notoginseng gardens, based on their habit of hiding by day and coming out at night, block their burrows during the day and place rat traps, rat cages

Effective weed control methods in Schisandra chinensis fields
1. The results of a survey of weed species in Schisandra chinensis fields showed that the weeds causing more serious damage in Schisandra chinensis fields include barnyardgrass, crabgrass, amaranth, lamb's quarters, field horsetail, green foxtail, and shortawn foxtail, among which crabgrass, Asiatic dayflower, and lamb's quarters are especially serious. 2. Conventional weed control in Schisandra chinensis orchards Conventional weed control in Schisandra chinensis orchards can be carried out together with intertillage of the orchard, 4 to 5 times per year, with a cultivation depth of about 10 cm, so that the soil is loose and has good aeration, and it also plays a role in drought resistance and water conservation. Weeding is an important means of avoiding nutrient loss and ensuring the plants have enough nutrition to grow healthily.

Key Techniques for Overwintering Management of Panax notoginseng Seedling Fields
Panax notoginseng is a perennial herbaceous plant. Once winter arrives, its above-ground parts all die back. At this time, the above-ground parts should be cut off 3 cm above the ground, and all dead branches, fallen leaves, diseased plants and weeds in the field should be cleared away and burned outside the field. The soil should be thoroughly sprayed and disinfected with 0.2-0.3 degrees Baume lime-sulfur mixture, and then a layer of decomposed farmyard manure should be applied at about 1500 kg per mu to keep warm and prevent freezing. If exposed roots are found, soil should be banked up when the winter fertilizer is applied, and finally a layer of grass should be spread on top to ensure the buds overwinter safely.
