Embodiment Construction

[0039] Angelica likes humid and cool climate and loose and fertile soil, and is mainly distributed in high-altitude areas of Minxian County and its adjacent counties. The following is a further explanation on the method of preventing early bolting of Angelica sinensis:

[0040] 1 Angelica cultivation climate environment: altitude 2200-2500m, annual average temperature 4.6°C-5.8°C, effective accumulated temperature ≥10°C 1550°C-1800°C, precipitation 550-650mm, sunshine hours 1600-1800h, frost-free period 100-130d; The soil is cultivated black hemp soil, the texture is medium loam, the fertility is uniform, and the previous stubble is broad beans;

[0041] 2. Agrochemical properties of angelica cultivation soil: 0-20cm soil organic matter 30.0-50.5g / kg, total nitrogen 3.000-5.000g / kg, total phosphorus 0.700-1.00g / kg, alkaline nitrogen 200-250mg / kg, available phosphorus 20.0-25.0mg / kg, available potassium 200.0-250.0mg / kg, pH 8.0-8.2.

[0042] 3. Select a good variety: choose M...

Abstract

The invention relates to a method for preventing and controlling early bolting of angelica sinensis. The method includes the steps that selection of climatic environment conditions suitable for cultivation of the angelica sinensis, determining of soil agricultural chemistry characters, selection of varieties, fertilizing of soil, control of planting density, determining of direct seeding time and a seeding method, field management and digging and harvesting at proper time. The direct seeding method is adopted; compared with an angelica sinensis transferring method, the method can prevent the angelica sinensis from bolting early, the early bolting rate of the angelica sinensis planted in the direct seeding method is zero, the cultivation cycle of the angelica sinensis is shortened, and primary agronomic characters and the yield of the angelica sinensis are obviously better than those in the angelica sinensis transferring method.

Description

technical field [0001] The invention relates to the cultivation technology of Chinese medicinal material Angelica sinensis, in particular to a method for preventing and treating early bolting of Angelica sinensis. Background technique [0002] Medicinal angelica is the dried root of the Umbelliferae plant Angelica sinensis, also known as Mingui, Qingui, Yungui, etc. It has the functions of nourishing blood and promoting blood circulation, regulating menstruation and relieving pain, moistening dryness and smoothing intestines, breaking blood stasis and promoting regeneration. Angelica, produced in Min County, Dingxi City, Gansu Province, has a good market for its high quality, high efficacy, and unique medical and health care functions. But for a long time, the phenomenon of early bolting in the cultivation process of Angelica sinensis is very serious. [0003] The planting of angelica is generally planted around the summer solstice in the first year to raise seedlings, plan...
