Abstract

The invention discloses a method for establishing mowing-type artificial grassland on a black soil beach. Introduced and acclimatized local grass seeds are selected. Annual forage grass Qingyin No.1/perennial forage grass Qingmu No.1 Elymus sibiricus, Elymus nutans/Qingmu No.1 Elymus sibiricus, or Elymus nutans/Elymus breviaristatus/Qingmu No.1 Elymus sibiricus are seeded at different seeding rates according to ecological and biological characteristics of forage grass and species niche in coenosis, so as to improve utilization efficiency of environmental resources (water, heat and light) and forage grass output and bring great economic and ecologic benefits. The method is suitable for establishing mowing-type artificial grassland at deteriorated grassland on the black soil beach with a soil thickness of more than 20 cm and a slope of less than 7 degrees.

Description

technical field [0001] The invention relates to a planting method for mowing-type black soil beach artificial grassland, in particular to an annual or perennial forage grass with large plant height, high yield and rich nutrition for the pasture grass and its combination, which is suitable for the alpine meadow secondary bare land on the Qinghai-Tibet Plateau—the black soil beach , through appropriate agronomic measures and technical means, plant artificial grassland for the purpose of restoration by mowing and using appropriate agronomic measures and technical means on the degraded black soil beach grassland with a soil layer thickness of more than 20cm and a slope of less than 7° in winter and spring grassland. Background technique [0002] For the purpose of mowing and utilization, select annual or perennial forage species with tall plants, high yields, and rich nutrient-rich pastures, and use comprehensive agronomy on degraded grasslands with a soil layer of more than 20 c...
