Abstract

The invention discloses a method for establishing a grazing artificial pasture on a black soil beach, which includes: firstly using locally introduced and domesticated local grass-seeds; and secondly, according to biological characteristics of forage grass and the principle of species niche in communities, mixing Qinghai Festuca sinensis, Qinghai Poa crymophila and Qinghai Poa pratensis according to a certain seeding proportion, mixing Elymus nutans or Elymus sibiricus Qingmu No.1, Qinghai Poa pratensis, Qinghai Poa crymophila and Puccinellia tenuiflora according to a certain seeding proportion, and mixing Elymus nutans or Elymus sibiricus Qingmu No.1, Qinghai Festuca sinensis, Qinghai Poa pratensis, Qinghai Poa crymophila and Puccinellia tenuiflora according to a certain seeding proportion, so that utilization rate of environmental sources (water, heat and light) is increased, and pasture service life is prolonged. The grass-seed combination and establishment technique is extensional, and with development of research and production practice, the combination and establishment technique is still expansible.

Description

technical field [0001] The invention relates to a grazing-type black soil beach artificial grassland planting method, in particular to the selection of grass species with good palatability and strong grazing tolerance and combinations thereof suitable for the alpine meadow secondary bare land on the Qinghai-Tibet Plateau—on the black soil beach. Agronomic measures and technical means are used to build artificial grasslands for livestock grazing purposes on flatlands with a soil layer thickness of more than 15cm and slopes less than 25° and on gently sloped heavily black soil flat degraded grasslands. Background technique [0002] For the purpose of livestock grazing and utilization, select grass species with good palatability and strong grazing tolerance, and use artificial measures to plant and improve them on beach land with a soil layer thickness of more than 15cm and a slope of less than 25°, and on gentle slope land with severe black soil beach degraded grassland The gr...
