Degraded rhizome grassland root cutting and soil loosening fertilizer applicator and rhizome grassland ecological restoration method

Abstract

The invention discloses a degraded rhizome grassland root cutting and soil loosening fertilizer applicator and a rhizome grassland ecological restoration method. The device comprises a rack, a left depth wheel mechanism, a right depth wheel mechanism, a cutter head mechanism, a soil loosening mechanism, a gear transmission, a fertilizer box bracket, a fertilizer box and a fertilizer discharging mechanism, wherein the left depth wheel mechanism and the right depth wheel mechanism are arranged at the front end of the rack; the cutter head mechanism is arranged at the lower end of the rack and onthe rear sides of the depth wheel mechanisms; the soil loosening mechanism is arranged at the rear end of the rack and on the rear side of the cutter head mechanism; the gear transmission is arrangedin the middle of the upper end of the rack; the fertilizer box bracket is arranged on the rack; the fertilizer box is arranged at the upper end of the fertilizer box bracket; the fertilizer discharging mechanism is arranged at the lower end of the fertilizer box through the fertilizer box bracket; and the cutter head mechanism comprises a cutter head shaft connected with the rack through a left shaft head and a right shaft head and a plurality of cutter heads evenly arranged on the cutter head shaft; a plurality of long-strip-shaped notches are evenly formed in the outer edge of each cutter head in the radius direction of each cutter head; and a diamond layer is arranged at the front end of each cutter head. The device is firm, durable, high in stability and good in root cutting effect, and three measures of root cutting, soil loosening and fertilization are completed through one-time operation.

Description

technical field [0001] The invention relates to the technical field of grassland ecological management and restoration, in particular to a root-cutting and loosening soil fertilization machine for degraded rhizome grasslands and a method for ecological restoration of rhizome grasslands. Background technique [0002] my country has 6 billion mu of natural grasslands, accounting for 41.7% of the country's land area. However, factors such as long-term overloading and overgrazing have degraded 90% of the grasslands to varying degrees. The restoration and management of the huge grassland degraded area urgently needs special machinery and equipment for grassland ecological restoration and supporting restoration methods. If there is no guarantee for special machinery and restoration methods, the efficiency of grassland ecological restoration and management will be greatly reduced, and the cost of restoration and management will increase exponentially. . Therefore, the development...

AI Technical Summary

Problems solved by technology

[0005] In recent years, some domestic scholars have continuously explored the improvement method of grassland root cutting. Some existing root cutting machinery mainly include root cutting cutter heads and three root cutting blades evenly arranged on the outer circumference of each cutter head. This root cutting structure It is easy to cause damage to the blade, and the impact force of the blade into the soil is relatively large, which has a great impact on the cutter head and the cutter shaft, and it is easy to bend the cutter shaft, resulting in poor equipment stability

[0006] Therefore, in the prior art, there is an urgent need for a degraded rhizome grassland cutting root loosening soil fertilizer applicator and a supporting rhizome grassland ecological restoration method that is strong and durable, has good equipment operation stability, and good effect of root cutting and fertilization, so as to solve the degradation of my country's natural rhizome grassland. Seriously, grassland loosening methods are outdated, existing loosening machinery has a large disturbance to the soil, and cannot meet key technical problems such as grassland improvement process requirements, providing effective ways and methods for my country's natural grassland ecological restoration and high-quality forage production
