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.
