Problems solved by technology

However, the moderately degraded grassland has been largely ignored, especially in the reseeding technology, the development of reseeding materials and technology is relatively lagging behind, which has affected the development of moderately degraded grassland restoration technology in alpine pastoral areas
[0003] The moderate degradation of the alpine pastoral area is characterized by the bare part of the land, which may take a long time for the simple enclosure measures, and als

Embodiment 1

[0022] A combination material for re-seeding of moderately degraded grassland in alpine pastoral areas, the formula of which is based on the weight of re-seeding per hectare: Elymus pachycarpa with a purity of more than 95%, 10 kg; old awn wheat with a purity of more than 95%, 10 kg; star grass with a purity greater than 95%, 5 kg; bluegrass with a purity greater than 95%, 5 kg; cattle and sheep manure 3,000 kg; superphosphate 150 kg; urea 40 kg. The above-mentioned alpine pastoral areas have an altitude greater than 4,500 meters, and the thickness of the soil layer is less than 15cm.

[0023] A specific method of using a combination material for reseeding moderately degraded grassland in alpine pastoral areas in reseeding degraded grassland is as follows:

[0024] 1) Weigh the seeds and fertilizers except urea according to the above formula, and mix them separately to obtain seed mixed material and fertilizer mixed material;

[0025] 2) Use disc rakes to lightly rake the gra...

Abstract

The invention discloses a reseed composite material of moderately degraded grasslands in a high cold pasturing area. According to the formula, the reseed composite material comprises elymus nutans of which the purity degree is greater than 95%, siberian wildrye of which the purity degree is greater than 95%, thinflower alkaligrass of which the purity degree is greater than 95%, poa crymophila of which the purity degree is greater than 95%, cattle and sheep manure, superphosphate and urea. The invention also provides an application method of the reseed composite material. Compared with other methods, the reseed composite material and the application method have the beneficial effects of high-density seed application amount, high protection role, stable colony, prevention of weed invasion, inhibition of weeds, prevention of losing of seed materials, prevention of high evaporation rate and the like; and the most important utilization of moisture in the critical period of plant growth is ensured by a technology of topdressing before rain.

Description

technical field [0001] The invention relates to the field of grassland management, in particular to a composite material for reseeding moderately degraded grassland in alpine pastoral areas and an application thereof. Background technique [0002] Restoration of degraded grassland is the core task of the Qinghai-Tibet Plateau land ecological barrier construction. More than 90% of the grasslands in the alpine pastoral areas of Tibet have been degraded. Therefore, it is an important scientific research task to study the restoration techniques and materials of the degraded grasslands in the alpine pastoral areas. At present, moderately degraded grassland occupies a large part of the alpine pastoral area. Under the concept of grassland restoration of mildly degraded grassland by enclosure and severely degraded grassland by reconstruction, the restoration technology of mildly and severely degraded grassland has been greatly developed. The moderately degraded grassland has been l...
