Embodiment 1

[0016] A method for pasture interplanting on the sunny side of the abandoned woodland with a slope greater than 20° in the alpine mountainous area. In the abandoned forest land in the alpine mountainous area with an altitude of 2000-2500m above sea level in the southwestern part of Yunnan Province, my country, the abandoned forest land with an altitude of 2000-2500m is interplanted with pasture on the sunny side of the slope with a slope greater than 20°. , the specific method is as follows:

[0017] (1) Sowing bed preparation: plow pasture sowing rows along the contour line between the tree planting pits, the distance between the pasture sowing rows is 28-32cm, and the sowing row depth is 13-17cm;

[0018] (2) preparation for sowing; prepare mixed sowing seeds according to seed sowing rate 2.5kg / mu; the mixed sowing ratio of described mixed sowing seeds is: 10% of annual ryegrass seeds, 30% of perennial ryegrass seeds, 30% of duckweed seeds, Clover seeds 30%. The amount of an...

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] 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 ...
