Abstract
Description
technical field
[0001] The invention belongs to the technical field of grassland mechanization improvement, and relates to a compound grassland improvement method and a special grassland working machine, in particular to an improvement method for natural or artificially degraded grassland and a special grassland working machine. Background technique
[0002] my country is rich in grassland resources, with nearly 400 million square hectares of various natural grasslands, accounting for 41.7% of the country's land area, 3.2 times and 2.5 times the area of ββcultivated land and forest respectively. Due to climate warming, rainfall reduction, long-term non-nutrition, overloaded grazing and trampling and grazing by livestock, the soil is severely compacted and has a high degree of firmness, which greatly affects the production and self-breeding of forage grass, and the grassland is seriously degraded.
[0003] Under the background of existing grassland improvement technology, soi...
