Method for planting forage grass on sunward side of hillside land with slope greater than 15 degrees in alpine mountainous area

Abstract

The invention relates to a method for planting forage grass on a sunward side of hillside land with the slope greater than 15 degrees in an alpine mountainous area. The method comprises the steps thatthe forage grass is planted in a rotation place in the alpine mountainous area with the altitude of 2,000-2,500 m in the southwestern Yunnan province of China, the sunward-side hillside land with theslope greater than 15 degrees is selected as the rotation place, and after former crops are harvested, the forage grass is planted; forage grass planting is conducted by adopting the mode that 9-11%of annual ryegrass seeds, 18-22% of perennial ryegrass seeds, 9-11% of hybrid ryegrass seeds, 28-32% of dactylis glomerata seeds, 28-32% of trifolium repens seeds and base fertilizer are mixed and sowed, and grazing can be conducted when the forage grass grows till the height of a grass layer exceeds 5 cm; when the forage grass is surplus, the harvested forage grass is dried and prepared into green hay or silage, and the stubble height during grass harvesting is 5 cm. The method for planting the forage grass in the alpine mountainous area has the advantages that the method is suitable for being implemented in the southwestern Yunnan province of China, and the forage grass is quick in propagation, good in growth and significant in ecological restoration effect.

Description

technical field [0001] The invention belongs to the technical field of forage planting, and in particular relates to a method for planting forage on the sunny side of a sloping field with a slope greater than 15° in an alpine mountainous area. Background technique [0002] The altitude area above 2000-2500 meters in the southwest of Yunnan Province in my country has a cold climate, low temperature, high soil humidity, little annual precipitation, rainy summer and dry winter. Most of the natural grasslands are barren grasslands, the land is barren, and the crops are cultivated by rotation. The grassland plants are mainly artemisia and ferns with low economic value, and the grassland vegetation coverage is low. In recent years, due to overgrazing and unreasonable development and utilization, the natural grassland has been seriously degraded, the grassland resources have been seriously damaged, large areas of rocky desertification have appeared, and the ecology has continued to...

AI Technical Summary

Problems solved by technology

However, forage planting is greatly affected by altitude, temperature, soil, precipitation, etc. Unscientific planting methods and unreasonable forage varieties will greatly affect the growth of forage and the effect of ecological restoration

Since there is no precedent and experience of large-scale planting of forage in the alpine mountainous area of ​​southwest Yunnan Province, the existing planting methods and test planting of forage varieties in northern my country are directly adopted, and all of them are inadaptable and have not achieved ideal results.
