Embodiment Construction

[0014] 1. Climate characteristics

[0015] Select the suitable regional climate as a humid temperate climate, a mid-cold climate, and a continental monsoon climate. The annual average temperature is 2.0°C to 7.5°C, the average temperature in January is -7°C to -19°C, the average temperature in July to August is 18°C ​​to 24°C, the accumulated temperature ≥10°C is 1900°C to 3100°C, and the annual average precipitation is 500mm to 1000mm , frost-free period 110d ~ 160d.

[0016] 2. Site selection

[0017] It is advisable to choose old ginseng land with aggregate structure, medium fertility, medium loam soil with good ventilation performance, and slope <15°.

[0018] 3. Rest and adjustment

[0019] Deep plowing at the end of April and early May, the depth of rotary plowing is 30cm~40cm, and stones are picked out during plowing, and perilla seeds are planted. 2 ~1200kg / 667m 2 ) into the soil together. Carry out 3 consecutive rotary tillages, the depth is more than 20cm, each...

Abstract

The invention relates to a continuous-cropping direct-seeding seedling culture method for American ginseng. The method includes the following steps: (1) selecting a region; (2) choosing soil; (3) performing deep tillage in late April or early May, planting perilla, ploughing perilla into soil together with waste agaricus bisporus bran before flowering, and spraying microbial agent before rotary tillage; (4) regulating the pH of soil to 5.5-6.5, and applying decaying farmyard manure in the amount of 500kg / 667<m2>-600kg / 667<m2>; (5) performing spring seeding in the next year. With the method, seedlings emerge evenly, pest and disease damage seldom happens in the second year, seedling survival rate reaches over 99%, and the problem of continuous cropping of American ginseng seedling culture is solved.

Description

technical field [0001] The invention relates to a method for continuous cropping of American ginseng. Background technique [0002] The growth of American ginseng likes forest ecological environment and woodland soil. Using old ginseng soil to cultivate American ginseng will cause low seedling germination rate, high seedling mortality, no root growth, root rot, and frequent pests and diseases, such as blight and black spots Diseases and epidemics, etc., the vaccination rate is extremely low, less than one-third. So far, the production of American ginseng in my country still mainly adopts the method of cutting forests and planting ginseng, which causes great damage and waste of forest resources and ecological environment. American ginseng cannot be replanted, resulting in problems such as high mobility in the ginseng field, high labor intensity, inconvenient transportation, and irregular operations due to changes in geographical conditions, which fundamentally limit the appl...
