Problems solved by technology

First of all, the no-tillage method usually used to improve natural grassland is not suitable for the northern grassland soil with high compactness and large volume, and the concentrated rainfall in the rainy season hinders the implementation of soil tillage; secondly, the higher soil salinity and pH value make Leguminous herbages are under great survival threat during the fragile seedling period; thirdly, the seasonal pattern of water resource

Embodiment Construction

[0031] Ground work treatment is carried out 1-2 weeks before the rainy season (in mid-June in the Songnen area). First, the above-ground vegetation is cut and removed, and the stubble height is 3-4cm. Then the trenching machine breaks the complete ground, the distance between the trenches is 65cm, the trench depth is 5-6cm, the upper width is 7-8cm, and the lower width is 1-2cm. Sow the polished seeds (to break the hard seeds) into the ditch. The sowing rate depends on the species and the later use method. If it is used as a mowing field, the effective seeding rate of leguminous pastures is: Xing'an Pediatricum 4.5-5kg / ha , black alfalfa 2.5-3kg / ha, alfalfa 3.5-4kg / ha. If it is used as a grazing land, the effective seed sowing rate is 9.5-10kg / ha of Xing'an clover, 4.5-5kkg / ha of yellow alfalfa, and 6.5-7kg / ha of alfalfa. Cover with soil 1-2cm, if the seeds are small (diameter<2mm), do not cover with soil. After the rainy season comes in late June, the salinity of the soil d...

Abstract

The invention relates to a method for planting semi-artificial grass, especially a method for leaking bean grass into the salinisation grass in north. The invention uses bean grass to improve the natural grass of dry area, especially using the rice-bean mixed plantation method. The invention can select the sowing time via the character of bean grass, the rain distribution, the salt change and the seed growth, and use management to reduce the competition between weak kinds, to accelerate the growth of seed. The invention has low cost, while it can improve the yield.

Description

technical field [0001] The invention belongs to a method for establishing and planting a semi-artificial grassland, and in particular relates to a method for introducing leguminous pasture into a saline-alkali grassland in the north to establish and plant a semi-artificial grassland. Background technique [0002] In natural grassland ecosystems, nitrogen deficiency is the main factor limiting plant growth. Leguminous pasture fixes nitrogen in the atmosphere through its symbiotic rhizobia and converts it into nitrogen nutrients that can be absorbed and utilized by other grassland plants. It is equivalent to a natural "nitrogen fertilizer factory" in the grassland ecosystem. At the same time, leguminous forage itself is a high-protein forage, which increases the protein content of the entire pasture. Leguminous forages play a very important role in improving nitrogen balance in grassland ecosystems and promoting grassland livestock production. [0003] In general, the richne...
