A reconstruction material for extremely degraded grassland in alpine pastoral areas and its application

Abstract

The invention discloses a rebuilding material for a high and cold pasturing area extremely deteriorated meadow. Calculated by the weight used in each mu, the formula of the rebuilding material is that 2.5kg elymus nutans with purity larger than 95%, 1.5kg elymus sibiricus with the purity larger than 95%, 1kg cold area bluegrass with the purity larger than 95%, 500kg cattle manure and sheep manure, 20kg calcium superphosphate and 20kg urea. The rebuilding material for the high and cold pasturing area extremely deteriorated meadow has the advantages that the formula and a method of the rebuilding material are offered, compared with other similar inventions, seed resources input is high, continuity and protective property of seeding are guaranteed, a community structure is reasonable and high in stability after vegetation is built, manure is sufficient, weed generation can be controlled in a short time, seeds and the manure can be kept in soil stably after being spread, and use of the urea for twice guarantees that sufficient nitrogenous manure is offered in a grass growing season.

Description

technical field [0001] The invention relates to the field of animal husbandry production, in particular to a reconstruction material for extremely degraded grassland in alpine pastoral areas and its application. Background technique [0002] The management and restoration of degraded grasslands has become an important task of production and ecological work in the alpine pastoral areas of the Qinghai-Tibet Plateau. There are two ways of thinking in the restoration of degraded grassland in alpine pastoral areas, one is to restore to the natural state; the other is to use artificial reconstruction to build artificial grassland. Of these two ideas, the first is adopted by most scientific researchers and local grassland management departments. The second type has also been promoted on a large scale in recent years, but due to the great controversy over the reconstruction materials, formulas, and methods, and the particularity of different regions, it is determined that it must b...

Problems solved by technology

The second type has also been promoted on a large scale in recent years, but due to the great controversy over the reconstruction materials, formulations, and methods, and the particularity of different regions, it is determined that it must be based on different ecological regions, environments, and climate conditions, as well as local conditions. Management level to decide whether the reconstruction is suitable

[0004] At present, the area of ​​extremely degraded grassland is increasing year by year in the alpine pastoral area of ​​Tibet above 4,000 meters above sea level, which brings great difficulties to the management of degraded grassland in this area
