Alpine area oat-common vetch mixed sowing method

Abstract

The invention relates to an oat-common vetch mixed sowing method which is suitable for the alpine areas of the Tibetan plateau. The method is as follows: from the mid-May to the early June per year, seeds are sowed, the sowing depth of the seeds of oat and common vetch is 2-4cm; the seeding rate of the gramineous pasture oat is 150-165kg / hm<2>, the seeding rate of the leguminous pasture common vetch is 75-82.5kg / hm<2>, and oat and common vetch are sowed in a mixed sowing ratio of 2:1. By adopting the mixed sowing method, the yield of the pasture can be increased, the protein content of the pasture can be increased, the palatability of the pasture can be optimized, the soil structure can be improved, the soil fertility can be increased and the bottleneck that the leguminous pasture is lack in the alpine pasturing areas of the Tibetan plateau during the development of the animal industry can be effectively alleviated.

Description

technical field

[0001] The invention relates to the technical field of planting artificial forage grass bases, in particular to a method for planting high-yield artificial forage grass in alpine pastoral areas. Background technique

[0002] There are 140 million hectares of natural grasslands distributed on the vast land of the Qinghai-Tibet Plateau, where about 70 million (only) livestock are grazing. It is one of the main pastoral areas in China. In the alpine pastoral area, the contradiction between grass and livestock is prominent, the lack of forage in winter and spring, and the lack of protein feed seriously hinder the sustainable development of regional animal husbandry (Liu Wei, Gan Youmin, Yan Donghai; 2000). Establishing high-yield, high-efficiency, and high-quality artificial grasslands is one of the keys to solving the seasonal imbalance between the supply and demand of alpine grasslands, protecting natural grassland resources and promoting the sustainable develo...
