Artificial planting method for recovering secondary bare land in alpine region

Abstract

The invention discloses an artificial planting method for recovering secondary bare land in an alpine region, and relates to the technical field of forestry. The method includes the following steps that grass seeds are sown in the pre-recovered alpine region in a uni-sowing or mixed sowing mode; according to uni-sowing, elymus nutans or siberian wildrye or stinkgrass flower or meadow grass or poacrymophila or festuca sinensis is sown; according to mixed sowing, mixed sowing of two or three or four of the elymus nutans, the siberian wildrye, the stinkgrass flower, the meadow grass, the poa crymophila and the festuca sinensis is adopted. By means of a multi-pasture mixed sowing mode, the vegetation growth state of the secondary bare land in the alpine region can be recovered, development ofthe forestry is facilitated, and the environment can be better protected.

Description

technical field [0001] The invention relates to the technical field of forestry, in particular to an artificial planting method for restoring secondary bare land in alpine regions. Background technique [0002] Secondary bare land means that although the original community has been eliminated, the soil conditions under the community are still somewhat preserved, and even the propagules of some plant species in the original community are preserved in the soil. Such bare land is called "secondary bare land". naked". [0003] Tanggula Mountain Town is located in the southwest of Qinghai Province, at 32°39′~34°48′ north latitude and 89°40′~92°55′ east longitude. The average altitude of the whole town is above 4700m. extremely fragile. The terrain is steep, the mountains are undulating, the area is full of snow-capped peaks, glaciers are widely distributed, and there are many water systems and lakes. It is the birthplace of the Yangtze River in my country; the air in the territ...
