Problems solved by technology

Traditional alfalfa planting methods are difficult to solve the problem of high mortality of alfalfa seedlings in mountainous alfalfa planting, especially in the spring planting process, this problem is more obvious
The high mortality rate of seedlings leads to low efficiency of grassland restoration improvement and artificial grassland construction, which not only wastes a lot of manpower, material resources and financial resources, but also makes it difficult to achieve the expected improvement and construction effect
The high mortality rate of seedlings also makes the yield of alfalfa significantly low, making it difficult to produce due economic benefits in that year

Embodiment 1

[0021] Ulukesay Township, Cele County, Hotan Prefecture, Xinjiang, at an altitude of 2,450 meters, chooses the local Hotan big-leaf alfalfa variety as the main plant variety, and rape as the companion variety;

[0022] selection

[0023] Choose the right variety. Alfalfa is a perennial plant. After one sowing, it can be used for at least 2-3 years, and at most it can be used for 4-5 years. The selection of seeds is the first step in the success of alfalfa planting. For standard big-leaf alfalfa seeds, the cleanliness of the seeds must reach 90%, the germination rate must reach 85%, and the purity must reach 98%.

[0024] Site preparation:

[0025] For the planting site, choose a place with a gentle slope in the front mountain belt of the mountainous area, with flat terrain and small slope fluctuations. The ground should be raked flat. The soil on the northern slope of Kunlun Mountain is sandy and does not need to be plowed;

Abstract

The invention relates to a double-layered growing method for lucern in mountainous areas of arid regions. The method is characterized in that: grandifoliate lucern is adopted as a main grown variety, an annual associated plant variety, such as rape, oat or highland barley, is chosen, and by means of a orthogonal test design and sowing order (position), growing spacing, growing depth, amount of applied fertilizer and other technical measures, and by utilizing the concealing and protectin effect generated by the double-layered growing method for the lucern in mountainous areas on lucern seedlings, the double-layered growing method can increase the current survival rate of the lucern seedlings. The double-layered growing method can promote the success of desert grassland improvement and artificial pasture construction under the environmental conditions of arid mountainous areas, becomes an optimal technology portfolio for growing lucern at medium and high altitudes in mountainous areas of arid regions, and greatly increases the survival rate of lucern in desert grassland restoration and artificial pasture construction and the yield of currently grown lucern in mountainous areas of arid regions at the altitude of 3000 to 1800 meters.

Description

technical field [0001] The invention relates to a method for double-layer planting of alfalfa in a mountainous area in an arid area, in particular to a method for double-layer planting of alfalfa in a mountainous desert grassland on the north slope of Kunlun Mountain in southern Xinjiang. Background technique [0002] Xinjiang is a large province of animal husbandry. Because it is located in the hinterland of the Eurasian continent and affected by the continental arid climate, Xinjiang's desert grassland accounts for more than 42% of the pastoral grassland area. The area of ​​desert grassland in southern Xinjiang accounts for 17.45% of the usable grassland area in Xinjiang, and it is mainly distributed on the northern slope of Kunlun Mountain at an altitude of 1800-3000 meters above sea level. It is an important winter pasture in the area. Desert grassland is not only the material basis for the livestock production of various ethnic groups in Xinjiang, but also plays a huge ...
