Problems solved by technology

And in recent years, the intensification of the greenhouse effect has led to narrower areas suitable for angelica seedlings, and seedlings have been extended to higher-altitude wastelands. The destruction of wasteland vegetation has aggravated the problem of water and soil erosion, which is very unfavorable for the sustainable development of the angelica industry and the protection of the ecological environment.

Embodiment 1

[0068] Step 1. Site selection:

[0069] The seedling breeding site of Angelica rehmanniae is located in Yinjiawan Village, Minzhu Township, Linxia County, Linxia Hui Autonomous Prefecture, Gansu Province. It is a winter wheat planting area with an altitude of 1800m, an annual average temperature of 5.8°C, and an annual precipitation of 450mm. The soil type is hemp soil;

[0070] Step 2. Pre-treatment of nursery ground:

[0071] Plow the soil immediately after harvesting the winter wheat in July. After plowing, apply 20,000kg / hm of decomposed farmyard manure in combination with the plowing 2 And apply diammonium phosphate 150kg / hm 2 , before planting, plow once again, pick out weeds and straw, prepare the site and mix well with microbial agent and fine soil, and then spread it on the surface for soil disinfection. The microbial agent includes Bacillus subtilis 45kg / hm 2 , Trichoderma harzianum 15kg / hm 2 , Metarhizium anisopliae 45kg / hm 2 , then shallow plowing and harrowing...

Abstract

The invention discloses a method for raising seedlings of winter wheat after-crop angelica sinensis and controlling early bolting rate. The method comprises the steps of land selection, seedling raising land pretreatment, seeding in the seedling raising period, field management in the seedling raising period, seedling lifting, seedling airing and storage. With adoption of the seedling raising of the winter wheat after-crop angelica sinensis, the seedling raising altitude is reduced, traditional wasteland is replaced with farmland, damage to vegetation is reduced, and the method is an eco-friendly seedling raising mode; the planting management is convenient, and the labor cost of land reclamation and high-altitude cultivation can be effectively reduced; and by means of the seedling raising of the winter wheat after-crop angelica sinensis, the use of fertilizer is reduced, the land utilization efficiency and multiple cropping index are improved, the production cost is saved, and farmer income increase and ecological environment protection are truly realized.

Description

technical field [0001] The invention relates to the technical field of raising seedlings of traditional Chinese medicinal materials, in particular to a method for raising seedlings of angelica after winter wheat and controlling early bolting rate. Background technique [0002] For a long time, the breeding of angelica seedlings has always followed the traditional method of growing seedlings in wasteland. Raising seedlings in raw wasteland does not occupy arable land, and the bred angelica seedlings have less pests and diseases and high yields, which increases the subjective dependence of pesticide farmers on raising seedlings in raw wasteland. Due to perennial reclamation of wasteland, the natural vegetation has been seriously damaged. In recent years, the intensification of the greenhouse effect has narrowed the area suitable for angelica seedlings, and the seedlings have been extended to higher altitude wastelands. The destruction of wasteland vegetation has intensified t...
