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] Wulukesayi Township, Cele County, Hetian Prefecture, Xinjiang, at an altitude of 2,450 meters, choose the local Hetian large-leaf alfalfa variety as the main plant variety, and rape as the companion variety;

[0022] Selection

[0023] Choose suitable varieties. Alfalfa is a perennial plant. After a single sowing, it can be used for at least 2-3 years, and at most 4-5 years. Seed selection is the first step for successful alfalfa planting, and it needs to be selected in line with the first and second level countries. For standard large-leaf alfalfa seeds, the purity of the seeds must reach 90%, the germination rate must reach 85%, and the purity must reach 98%. The seeds should be dressing before sowing, and the amount of seeds per mu should be controlled at 0.8-1.0 kg;

[0024] Site preparation:

[0025] Choose a place with a gentle slope in front of the mountainous area for planting, flat terrain and small slope undulations, and rake the ground. The soil on the northern slope...

Embodiment 2

[0035] Bostan Township, Cele County, Hotan Prefecture, Xinjiang, at an altitude of 3,000 meters, the local Hetian large-leaf alfalfa variety is selected as the main plant variety, and the highland barley is the companion variety;

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 double-layer planting method of alfalfa in mountainous areas in arid areas, and in particular to a double-layer planting method of alfalfa in the middle-high altitude mountainous desert grassland on the northern slope of Kunlun Mountain in southern Xinjiang. Background technique [0002] Xinjiang is a major animal husbandry province. Because it is located in the hinterland of Eurasia and affected by the continental arid climate, the desert grassland in Xinjiang accounts for more than 42% of the grassland area in the pastoral area. The desert grassland area 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. It is an important local winter pasture. Desert grassland is not only the material basis for the various ethnic groups in Xinjiang to engage in animal husbandry production, but also plays a hu...
