Cultivation technique of high quality and high yield forage grass for barley multiple-planting oats in Alpine region of North China

Abstract

The invention relates to the cultivation technique of high quality forage grass, that is, a cultivation technique of high quality and high yield forage grass for barley multiple-planting oats in Alpine region of North China, in particular to the cultivation technique of the high quality and high yield forage grass, which can produce two stubble of forage grass a year and increase forage yield in the Alpine region of North China according to the growth characteristics of barley and oats and requirements of ecological environment. The cultivation technique specifically includes the integrated technology of variety selection, sowing time, sowing mode, sowing quantity, harvesting mode, multiple planting mode and the like. The farming system of forage planting once a year in the Alpine region of North is changed, the multiple planting index is increased, plastic films are not used, the amount of water, fertilizer and pesticides is reduced, less straw residue is caused, environmental pollution is reduced, the optimal selection mode of rotation stubble is achieved, the supply capacity of the forage grass is improved, the pressure of natural grassland is alleviated, and higher ecological,social and economic benefits are achieved.

Description

technical field [0001] The invention relates to a high-quality and high-yield forage grass cultivation technique, in particular to a high-quality forage grass cultivation technique for multi-planting oats with barley in the northern alpine region. Background technique [0002] The northern alpine region is a traditional oat and barley planting area, and the planting area is relatively large. Before promoting the present invention, this area planted a crop of field crops every year, mainly based on harvesting seeds, and partly harvested forage crops. Barley and oats were harvested as hay. 300kg / mu-400kg / mu, the yield is low, and the quality of forage grass is poor due to unreasonable mowing time. However, with the rising costs of labor, land rent, and fertilizers, the benefits of barley and oat planting are relatively low, farmers and herdsmen have low income, or even lose money, backward management, and uneven varieties. [0003] Animal husbandry is relatively developed in ...

In addition, the planting area of ​​potatoes and sunflowers is increasing year by year. The continuous planting of potatoes and sunflowers leads to the decline of arable land fertility, serious residues of pesticides and fertilizers. At the same time, continuous farming leads to a decrease in production, and the annual sales market price is unstable. Poor, large areas of sunflower and potato stubble land need crop rotation and stubble, and farmers and herdsmen generally use barley and oats as stubble crops, and farmers and herdsmen have very low income or even lose money. Therefore, it is urgent to broaden the planting ideas and explore a high-yield and high-quality Forage planting mode is imperative
