A method for establishing pasture grass on the sunny side of abandoned forest land with a slope greater than 20° in alpine mountainous areas

Abstract

A method for planting pasture on a sunny side with the gradient larger than 20 degrees in abandoned woodland of a cold highland area includes the steps of planting the pasture on the slope sunny sidewith the gradient larger than 20 degrees in the abandoned woodland in the cold highland area at the altitude of 2000-2500 m in the southwest of the Yunan Province in China, wherein 9-11% of annual ryegrass seeds, 28-32% of perennial ryegrass seeds, 28-32% of orchardgrass seeds and 28-32% of trifolium repens seeds are sown in a hybrid mode during pasture plantation; conducting herding when the pasture grows to have a grass layer height larger than 5 cm; cutting the pasture to be aired into green dry grass or ensilage when the pasture is surplus, wherein the crop reserving height is 5 cm duringpasture cutting. The cold highland area pasture planting method is suitable for being implemented in the southwest of the Yunan Province in China, and the planted pasture is rapid in reproduction, good in growth and remarkable in ecological repairing effect.

Description

technical field [0001] The invention belongs to the technical field of pasture planting, and in particular relates to a method for planting pasture on the sunny side of a sloping field with a slope greater than 15° in an alpine mountainous area. Background technique [0002] In the southeast of Yunnan Province in my country, the altitude of 2000-2500 meters above sea level is cold, the temperature is low, the soil humidity is high, the annual precipitation is small, the summer is rainy, and the winter is dry. 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 appeare...

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 grass in the alpine mountainous area of ​​southeastern Yunnan Province, the existing planting methods and test planting of pasture varieties in northern my country are directly adopted, and all of them are inadaptable and have not achieved ideal results.
