Problems solved by technology

Due to the special geographical location and climatic conditions of the Qinghai-Tibet Plateau, the production method is still in a traditional state. There is no arable land to develop artificial forage production, and it is almost impossible to supplementary feeding by planting outside the area.

Embodiment 1

[0023] The method for improving the alpine meadow steppe on the Qinghai-Tibet Plateau to mowing grassland includes the following steps:

[0024] 1) Grassland selection: Select alpine meadows and grasslands that are flat and suitable for irrigation near the water source area on the Qinghai-Tibet Plateau at an altitude of 2800-3200 meters, and carry out comprehensive eradication of underground pests and ground pests, and prohibit grazing throughout the growing season;

[0025] 2) Ground leveling treatment: the grassland selected in step 1) is treated with ground leveling, zokor mound leveling and bald spot guest soil;

[0026] 3) Select supplementary grass seed and mixing ratio: choose Elymus chinensis, Chinese fescue, bluegrass (or bluegrass), and mix according to the mass ratio of 2:1:1;

[0027] 4) Cutting the turf and re-seeding: Use a turf cutting machine to cut the turf with a row spacing of 25cm and a depth of 5cm, and sow the mixed seeds obtained in step 3) in the ditch....

Abstract

The invention discloses a method for modifying the Tibet plateau alpine meadow grassland into mowing grassland. The method for modifying the Tibet plateau alpine meadow grassland into the mowing grassland comprises (1) a step of selection of the grassland, (2) a step of flattening of the ground, (3) a step of selection of resowing grass seeds and a mixing ratio, (4) a step of turf cutting and resowing, (5) a step of determination of fertilizer type and fertilizer amount, (6) a step of determination of irrigation method and irrigation amount, (7) a step of management, and (8) a step of mowing and harvest. The method for modifying the Tibet plateau alpine meadow grassland into the mowing grassland has the advantages that comprehensive modification measures can promote the growth of forage grass, especially irrigation and fertilization can promote the nutritional growth of the forage grass and restrain reproductive growth, so that the forage grass is tender in stalk and rich in foliage. Mowing can control the growth of noxious weeds, promotes compensatory growth or over-compensatory growth of fine forage. Through comparison, the height of a grass layer, and the yield and the quality of forage grass are all largely improved.

Description

technical field [0001] The invention relates to a method for improving the alpine meadow on the Qinghai-Tibet Plateau into a high-yield and high-quality mowed pasture. Background technique [0002] Grassland on the Qinghai-Tibet Plateau is degraded, productivity is declining, forage supply is seriously insufficient, and the contradiction between grass and livestock is prominent. The lack of grass in winter and spring has become a bottleneck restricting the development of local animal husbandry. The animal husbandry is in a state of "summer full, autumn fat, winter thin, spring lack The income increase of farmers and herdsmen is mainly achieved by increasing the number of livestock, and the contradiction with grassland ecological environment protection has become increasingly prominent. Due to the particularity of the geographical location and climatic conditions of the Qinghai-Tibet Plateau, the production method is still in the traditional state. There is no arable land to ...
