Problems solved by technology

The application uses quantitative fertilization, and the fertilizer is phosphorus, potassium compound fertilizer or organic fertilizer, and does not carry out targeted fertilization according to the soil quality of the planting soil, resulting in poor alfalfa rhizome development, resulting in low overwintering rate and low emergence rate of alfalfa
Sowing by ridges and precision drills is not conducive to the emergence of alfalfa. After ridges, alfalfa is planted in gullies, which is not conducive to mechanized operations. The thin soil layer cannot effectively ensure the sowing depth of alfalfa seeds, which is not conducive to the overwintering rate of alfalfa. improvement

Abstract

The invention discloses an alpine-semiarid-area alfalfa seeding method. The method includes steps: variety selection, fine soil preparation, formula fertilization and mulching precise hole sowing, wherein the step of formula fertilization specifically includes: analyzing and testing soil nutrient of a planting land plot, preparing organic compound fertilizer according to nutritional needs of alfalfa and condition of soil nutrient, and applying the prepared compound fertilizer onto the planting land plot; the step of mulching precise hole sowing includes full mulch covering, earthing and compacting and holing and hole sowing, full mulch covering refers to fully covering the planting land plot after going through the step of formula fertilization with mulch, earthing and compacting refers to covering the mulch with a layer of soil, and holing and hole sowing refers to holing the mulch after going through earthing and compacting and sowing alfalfa seeds in holes and then earthing. By the method, wintering rate of alfalfa can be ensured effectively, seedling emergence rate of alfalfa can be increased, unit area yield of alfalfa can be increased, mechanical action is facilitated, and convenience is brought to harvesting.

Description

technical field [0001] The invention relates to a method for sowing grass, in particular to a method for sowing alfalfa in alpine and semi-arid regions. Background technique [0002] Alfalfa is known as the "King of Forage Grass". It not only has high yield, but also has excellent grass quality, and all kinds of livestock and poultry like to eat it. The current planting area of ​​alfalfa in my country is about 1.33 million hm 2 . With the development of commodity economy, the scale of alfalfa industrialization has developed rapidly in recent years, and the planting area of ​​alfalfa is expanding. The primary roots of alfalfa can go deep into the ground. When the plant grows for more than 20 years, if the subsoil is porous, the tap root can reach a depth of more than 15 meters (50 feet), so alfalfa is extremely tolerant to drought. The roots of the seedlings can penetrate 90 centimeters into the soil when they grow for 2 months, and reach 180 centimeters (6 feet) when the...
