Method for reducing early bolting of Chinese angelica

Abstract

The invention discloses a method for reducing the early bolting of Chinese angelica. The method includes selecting black soil and heilu soil with excellent conditions to perform sowing, the period ofcrop rotation being more than 3 years, performing shallow ploughing for one time before sowing, applying well-rotted farmyard manure, urea, diammonium phosphate and potassium sulfate before the soil is turned up, and killing pests; then transplanting seedlings, and selecting soybean seeds to perform dibbling; performing sterilization on the seedlings before transplanting, and performing air-dryingwhile performing soaking; performing transplanting in mid-to-late March, performing covering with wide films to perform dibbling, and planting one row of soybeans and three rows of Chinese angelica after mulching; during the transplanting of the Chinese angelica, respectively planting one seedling on the two sides of each hole, the distances of the terminal bud on the heads of the seedlings of the Chinese angelica from the mulching films being 2-3 cm, performing compacting with fine soil, and tightly sealing broken gaps; and during the dibbling of the soybeans, putting 2 soybean seeds in eachhole, performing compacting with the fine soil, and tightly sealing the broken gaps. The bolting rates after the intercropping of the Chinese angelica and the soybeans are lower than that of the monoculture of the Chinese angelica; the influence of different intercropping ratios on the bolting rates is different; when the Chinese angelica is intercropped with the soybeans in a ratio of 3:1, the bolting rate of the Chinese angelica is the lowest, which is only 26.06%; and the annual growth rate of the Chinese angelica can reach up to 66%.

Description

technical field [0001] The invention relates to the field of planting Chinese medicinal materials, in particular to a method for reducing early bolting of angelica. Background technique [0002] Angelica is a plant of the genus Angelica in the family Umbelliferae, also known as Qingui. It is mainly produced in Gansu, Yunnan, Shaanxi, Sichuan and other provinces. It is a commonly used Chinese medicinal material in my country. It is known as "ten directions and nine returns". Treatment and prevention of cerebrovascular diseases, respiratory diseases, bone and joint diseases, muscle tissue diseases, etc. The conventional production cycle of Angelica sinensis is 3 years. Seedlings are sown in June to July in the first year, stored in late October, transplanted in March to April in the second year, and the fleshy roots are harvested in autumn for medicinal purposes. The strains bloom and bear fruit, and the seeds are harvested. [0003] The whole growth period of Angelica sinens...

Problems solved by technology

If the purpose is to harvest angelica medicinal materials, it is enough to complete the first two stages. However, the phenomenon of early bolting of angelica in the second year is common in production. Once bolting, the underground roots of angelica will be lignified and lose their medicinal value. , this phenomenon is called Angelica "early bolting"

Pulling out the bolting plants after early bolting will cause lack of seedlings and broken ridges in the field. In order to protect the seedlings, double seedlings are often planted in the field when transplanting. Resulting in increased planting costs, reduced yield and quality

[0004] At present, there are many studies on the anti-early bolting of Angelica sinensis. The main methods include breeding fine varieties, selecting high-altitude areas to raise seedlings to control the size of seedlings, using shading, controlling nitrogen fertilizer, applying plant growth regulators and high-density planting, keeping seedlings in the middle period, and pulling out. Bolting seedlings, etc., but the anti-early bolting effect of these methods is not obvious, the main reason is that the angelica seedlings have passed the low-temperature vernalization stage, so that they have the conditions for early bolting

In addition, the rate of Angelica sinensis in the planting process is too high, which seriously affects the medicinal quantity and quality of Angelica sinensis.

[0005] In order to overcome the problem of early bolting in the existing angelica cultivation process, the object of the present invention is to provide a method for preventing and treating early bolting of angelica, so as to solve the problem that the early bolting of angelica sinensis is serious and affects the production of angelica.
