Problems solved by technology

At present, in production, the rate of "early bolting" is reduced by controlling the environment of angelica seedlings, such as altitude, wasteland, shady slopes, etc., controlling the time of seedlings and the size of seedlings, and selecting appropriate seeds. However, these measures are blind and Uncertainty, the bolting problem of Angelica sinensis has not been well resolved so far, and it is still a prominent problem that plagues the high-quality and efficient cultivation of Angelica sinensis, and there is no effective way to eliminate the "early bolting" of Angelica sinensis

Embodiment 1

[0025] Dacaotan Township, Zhangxian County, with an altitude of 2500m and a rainfall of 530-680mm, is selected. The climate is obviously cold and humid, and it belongs to a warm and semi-humid continental monsoon climate. Loose and fertile soil, soil organic matter content 18.7 g / kg, total nitrogen 1.7 g / kg, total phosphorus 0.8 g / kg, total potassium 26.7 g / kg, alkaline nitrogen 93.8 mg / kg, available phosphorus 30.3 mg / kg, available potassium 95.8 mg / kg. Angelica seeds were provided by Minxian Angelica Research Institute.

[0026] In 2012, the spring direct-seeding cultivation and density experiment of Angelica sinensis was carried out in Dacaotan Township, Zhang County. The two-factor experiment of covering method and density was adopted. The covering method was set to cover Bupleurum stalks, covered wheat grass, and covered with plastic film. The density was set at 53,000 plants / 666.7 m 2 (Row spacing×plant spacing is 25cm×5cm), 38,000 plants / 666.7m 2 (25cm×7cm), 30,000 p...

Embodiment 2

[0057] Select an area with an altitude of 2500m and annual rainfall ≥ 500mm as the direct-seeding cultivation area. When planting angelica in this area, continuous cropping is not suitable, and the crop rotation cycle is required to be at least 3 years. The previous crops are preferably wheat, flax, rape or corn; After the crops are harvested, deep plow in time, with a deep plowing depth of 25cm; commercially available Xinqing new mineral organic fertilizer (produced by Lanzhou Xinqing Co., Ltd.) is applied to the deep plowed soil, and the fertilization rate is 6000kg / hm 2 Before sowing, spread the fertilizer evenly on the surface, plow and bury the fertilizer fully, and harrow it level; in spring, sow when the temperature of the soil layer 5cm below the surface reaches 6°C; when sowing, open shallow trenches with a row spacing of 25cm and a depth of 2cm Level the bottom of the ditch, sprinkle the seeds evenly into the ditch, and cover the wet soil with a thickness of 0.5cm, so...

Embodiment 3

[0059] Select an area with an altitude of 1500m and an annual rainfall of ≥500mm as the direct-seeding cultivation area. When planting angelica in this area, continuous cropping is not suitable, and the crop rotation cycle is required to be at least 3 years. After the crops are harvested, plow deep in time, with a deep plowing depth of 30cm; apply commercially available Xinqing new mineral organic fertilizer (please give the product name) to the soil after deep plowing, and the fertilization rate is 3000kg / hm 2 Before sowing, spread the fertilizer evenly on the surface, plow and bury the fertilizer fully, and rake it level; in spring, sow when the temperature of the soil layer 5cm below the surface reaches 8℃; Level the bottom, spread the seeds evenly into the ditch, and cover the seeds with wet soil with a thickness of 1cm, so as not to see the seeds; then, evenly cover the wheat straw with a thickness of 3cm to keep the soil moist and facilitate the emergence of seedlings; th...

Abstract

The invention provides a cultivation method capable of preventing Angelica sinensis from premature bolting. The cultivation method comprises the following steps: deeply plowing soil and fertilizing at a planting area; sowing when the temperature of soil layer of 5 cm below the ground surface is 6-8 DEG C, wherein the row spacing is 20-25 cm, opening shallow gullies with the depth of 2-3 cm, after sowing, covering wet soil, and then covering wheatgrass, wherein the seedling density per hectare is 0.45-0.75 million plants, and the plant spacing is 5-10 cm; when the height of seedling is 3-4 cm, gapping and establishing so as to keep the plant spacing and the seedling density; sowing in late October of the present year, digging and sunning when the aerial part is withered so as to obtain the Angelica sinensis. According to the cultivation method, under the precondition of ensuring the yield and quality of Angelica sinensis, the Angelica sinensis is prevented from premature bolting, the seedling and transplantation procedures of Angelica sinensis are omitted, the production period of Angelica sinensis is shortened, 25% of seedling and seedling storage land is saved, and 120-130 days of production period of Angelica sinensis are shortened.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a cultivation method of angelica sinensis, in particular to a cultivation method for avoiding early bolting of angelica sinensis. Background technique [0002] Gansu Province is the national angelica ( Angelica Sinensis Oliv.Diels) is the province with the largest planting area, mainly distributed in Minxian, Zhangxian, Dangchang, Weiyuan and other places, among which Minxian is the traditional place for producing angelica. The whole growth period of Angelica sinensis spans two winters and three years, and its cultivation can be divided into seedling raising stage, medicine making stage and seed production stage. The first stage is the seedling raising stage around the summer solstice (mid-to-late June) to the cold dew (mid-to-late October), and the seedlings are stored in late October; the second stage is transplanting around the Qingming Festival in the second year (ar...
