Method for quickly planting grass-legume mixed sowing grassland in wind sand ground of Mongolia and Liaoning agro-pastoral transition zone

Abstract

The invention belongs to the planting method field of rapid restoration of perennial vegetation in a wind sand ground, and discloses a method for quickly planting grass-legume mixed sowing grassland in the wind sand ground of a Mongolia and Liaoning agro-pastoral transition zone. According to the method, the problems of vegetation degradation, grassland productivity decline and low forage grass quality are solved through adding spatial distribution uniformity of Chinese wildrye and an alfalfa, and the seed seeding rate. The method includes the steps that 1, ground is leveled and weeds are cut; 2, seeds are sowed, specifically, the mass radio between the Chinese wildrye and the alfalfa is 7:1, and then the seeds are mixed and then planted in rows by dividing furrows; and 3, administrationand management are conducted, specially, watering is conducted on a seedling stage, and harvesting is conducted before the middle of August. The method of quickly planting the grass-legume mixed sowing grassland in the wind sand ground of the Mongolia and Liaoning agro-pastoral transition zone has the advantages that seedling mucking earth rate, the settlement rate and the resume growth rate are increased, the cost is low, a planting period is short, popularization is easy and the like; and soil fertility can be added, the weeds are controlled, the yield and quality of pastures are increased,and degradation vegetation in the wind sand ground can be recovered quickly.

Description

technical field [0001] The invention belongs to the field of planting methods for rapid recovery of perennial vegetation in windy and sandy land, and relates to a method for quickly building grassland-bean mixed sowing grassland in the windy sandy land of the Mongolia-Liaoning agriculture and animal husbandry transition zone. Background technique [0002] The interlaced area of ​​agriculture and animal husbandry is the ecological transition zone connecting the agricultural planting area and the grassland animal husbandry area, also known as the semi-agricultural and semi-pastoral area or the ecologically fragile zone. It is a unique and important industrial interface, and an important ecological barrier to curb grassland desertification and desertification transfer. Its distribution runs obliquely from northeast to southwest of my country, and is on an important dividing line between my country's ecological environment and regional economy. As the interface connecting the tw...

Problems solved by technology

In addition, in the agricultural and animal husbandry interlaced area of ​​Mengliao, the soil is generally in a state of aeolian sandification. There are different characteristics of land aeolian sandification in the dry and wet seasons. It is generally not obvious in the rainy season, but it will be intensified in the dry and windy season. The sandy land gradually expands and spreads, leading to land degradation, many vegetation cannot grow normally, the productivity of grassland decreases, the service function of ecosystem decreases, and the contradiction between grassland and livestock intensifies
