Abstract

The invention discloses a method for establishing an ecological artificial pasture on a black oil beach, which includes: firstly, selecting locally introduced and domesticated local grass-seeds; and secondly, according to the ecological and biological characteristics of forage grass and the principle of species niche in communities, mixing Elymus nutans, Leymus and Puccinellia tenuiflora according to a certain proportion, mixing Elymus nutans, Leymus, Stipa penicillata and Roegneria thoroldiana according to a certain proportion, and mixing Elymus tangutorum, Qinghai Poa pratensis, Puccinellia tenuiflora, Stipa penicillata and Roegneria thoroldiana according to a certain proportion, so that utilization rate of environmental sources is increased, the established artificial vegetation is highly stable, and the ecological benefit is evident. The method is applicable to establishment of ecological artificial pastures on deteriorated grassland of all black soil beaches with soil thickness more than 15cm.

Description

technical field [0001] The invention relates to an ecological black soil beach artificial grassland planting method, in particular to a perennial grass species suitable for the alpine meadow on the Qinghai-Tibet Plateau—the black soil beach, which has strong adaptability, is easy to form turf, and has a strong water and soil conservation ability. Its combination, through appropriate agronomic measures and technical means, establishes artificial grasslands for the purpose of water and soil conservation, windbreak and sand fixation, and water conservation on all types of degraded grasslands in Heishangtan with a soil layer thickness of more than 15cm. Background technique [0002] With the restoration purpose of water and soil conservation, windbreak and sand fixation, and water conservation, perennial grass species with strong adaptability, easy formation of turf, and strong water and soil conservation ability are selected, and artificial measures are used to build on all type...
