Method for establishing artificial mixed sowing grassland of slope of loess plateau

Abstract

The invention relates to a method for establishing artificial mixed sowing grassland of a slope of a loess plateau. When seeds are sown in the area of the loess plateau, leguminous grass seeds and gramineous forage grass seeds are sown in a mixed manner, and alfalfa seeds and awnless brome seeds are sown in the mixed manner according to the proportion of 0.3:0.7; and during sowing of the mixed sowing grassland, the suitable fertilizing amount includes that nitrogenous fertilizers (pure N) are 85kg / hm(2), potash fertilizers (K2O) are 110kg / hm(2), and phosphatic fertilizers (P2O5) are 70kg / hm2. By reasonably matching leguminous grass and gramineous forage grass, the artificial mixed sowing grassland with the alfalfa and the awnless brome seeds is formed, grassland vegetations with different types are combined with each other, so that soil erosion of waste mountains of a loess area can be effectively reduced, the richness degree of the species of the grassland is increased, and the natural renewability of the grass is improved.

Description

technical field [0001] The invention relates to the field of plant establishment, in particular to a method for establishment of artificial grassland with mixed sowing on sloping land of the Loess Plateau. Background technique [0002] Since the implementation of the project of returning farmland to forest and grass and closing mountains and prohibiting grazing in the loess area, the vegetation restoration of barren hills and degraded grasslands has achieved remarkable results, but the utilization of slopes is still not high, and the masses cannot effectively use them for grazing. The problem is that the establishment of artificial grasslands is unreasonable. [0003] Disadvantages of the prior art: confusion in the selection of grass species during the establishment of mixed sowing grassland; ratio of grass species; unreasonable fertilization. [0004] In view of the above-mentioned defects, the author of the present invention has finally obtained this creation through long...
