Planting method of alfalfa in alpine pastoral area

Abstract

The invention discloses a method for planting alfalfa in an alpine pastoral area, comprising the steps of: S1, site selection: selecting sandy loam or loamy plots with flat terrain, good drainage, and deep soil layers; S2, site preparation and fertilization: including Blocks are followed by the steps of applying base fertilizer, plowing and raking; S3, seed selection and planting: specifically include the steps of seed selection, seed cleaning and sun-drying treatment, mixed seed treatment and sowing; S4, field management: including topdressing and The step of irrigating; S5, mature harvesting. Through a series of measures taken in each step, the successful establishment of alfalfa in the alpine pasture area, on the one hand, solves the problem of a single herb species in the artificial grassland in the alpine pasture area, and on the other hand, it can increase the protein yield per unit area of ​​the pasture, and improve the quality and utilization of the pasture. It can effectively make up for the lack of protein nutrition of livestock in winter and spring dry grass period in alpine pastoral areas, improve the quality of artificial grasslands, and enhance the ecosystem functions of artificial grasslands in alpine pastoral areas.

Description

technical field [0001] The invention relates to the technical field of pasture cultivation in alpine pastoral areas, in particular to a method for planting alfalfa in alpine pastoral areas. Background technique [0002] Alfalfa (Medicago L.), Fabaceae, Papilionaceae, Medicago genus, widely distributed in Europe, Asia, America and Africa, there are more than 60 species in the world, 16 species in my country, widely distributed, wild and cultivated . Alfalfa is the earliest and most widely planted forage grass in the world. Alfalfa is known as the "King of Forage Grass". It not only has high yield, but also has excellent grass quality. In the alpine pastoral area of ​​Qinghai Province, the altitude is high, the climate is dry, cold, windy and sandy in winter and spring, and the growing time is short in the warm season. The general sowing method is used to plant leguminous herbage. Due to the limitation of natural conditions, it is difficult to successfully plant alfalfa in the...

Problems solved by technology

However, limited by natural conditions, the introduction and cultivation of leguminous forages in alpine pastoral areas is generally Arrowhead pea. As an annual climbing herb, Arrowhead pea cannot grow upright by itself and needs to be planted every year, which significantly increases the planting cost and cannot Mixed sowing of grass and beans with perennial grass forages to achieve the purpose of one-time planting for many years of sustainable use
