Establishment method of mowing type natural clipping pasture in northwest Sichuan alpine pastoral regions

Abstract

The invention discloses an establishment method of a mowing type natural clipping pasture in the northwest Sichuan alpine pastoral regions, and belongs to the technical field of pasture establishment.With the core goal of improving the output of forage grass on the natural pasture, the local fine grass species suitable for growing in the northwest Sichuan alpine pastoral regions are subjected tooptimizing combination, through comprehensive agronomic measures such as cutting turf, ground disturbance, reseeding grass seeds and fertilizer spreading, the high-quality mowing type natural clippingpasture is built, the production capacity of the grass forage on the natural pasture is improved, and the purpose of producing high-quality green hay bales is achieved. The core content of the establishment method includes grass seed combination and a supporting establishment technology, and the establishment method can be achieved through the following technical schemes: following the basic principle of "local priority", the production performance and mowing-resistant ability are taken as main screening indicators, through many years of field test comparison, the perennial local fine foragegrasses and forage varieties, including Sichuan grass No.2 elymus sibiricus, Aba elymus nutans, Kangba elymus nutans and Qinghai meadow grass, suitable for planting in the northwest Sichuan alpine pastoral regions are screened out,.

Description

technical field [0001] The invention relates to the technical field of grassland establishment and planting, in particular to a method for establishing a mowing-type natural grassland in the alpine pastoral area of ​​northwestern Sichuan. Background technique [0002] The pastoral area in Northwest Sichuan is located in the northwest of Sichuan Province and is an important part of the "Qinghai-Tibet Plateau ecological barrier". Grassland animal husbandry is an important foundation and pillar industry for regional economic development. The region has a special geographical environment, harsh climatic conditions, and a fragile ecological environment. The extensive production and management mode of "relying on the sky to raise livestock" still exists widely. In recent years, under the influence of multiple factors such as global warming, population increase in pastoral areas, and overgrazing of grasslands, the ecological environment of grasslands has deteriorated day by day, an...

Problems solved by technology

[0005] The main defects of the existing mowing-type natural mowing field planting methods are as follows: single forage species, unreasonable combination and matching, imperfect planting technology and poor matching of mechanical equipment, resulting in poor community stability and difficult forage yield. Stable and high yields are not conducive to mechanized mowing operations, resulting in the failure to effectively reflect economic benefits and restricting the development of forage grass industry in pastoral areas in northwestern Sichuan
