Description

TECHNICAL FIELD

[0001] The utility model belongs to soil mulching technical field especially relates to a bare land mulching equipment for saline and alkaline soil improvement. BACKGROUND

[0002] Saline and alkaline soil improvement is a process of improving soil structure, reducing soil salinity and improving soil fertility to promote plant growth through a series of technical measures. Traditional saline and alkaline soil improvement methods such as large water flushing and mulching, although can inhibit surface salt and lock water to some extent, often have repeated effects and cannot fundamentally solve the problem. The "mulching under straw" technology is an innovative saline and alkaline soil improvement method, which effectively blocks the upward movement of salt, reduces soil salinity, and improves seedling survival rate and crop yield by laying straw underground and mulching on the ground. Therefore, a bare land mulching equipment for saline and alkaline soil improvement is needed.
