Compound deep loosening shovel and compound deep loosening method

Abstract

The invention discloses a compound deep loosening shovel, which comprises a fixed plate provided with a feed port of the fixed plate, a shovel arm and a shovel head; A feeding pipe; the fixed plate and the shovel head are respectively fixed on the upper and lower ends of the shovel arm, and the rear side of the shovel head is provided with a discharge pipe corresponding to the feeding pipe, and the upper ends of each feeding pipe are fed into the fixed plate. The feed port of the fixed plate is connected with the discharge port of the silo of the applicator, the lower end of each feed pipe is connected with the upper end of a discharge pipe, and the lower end of each discharge pipe is provided with an external connection. Outlet. The invention also discloses a compound deep loosening method using the above compound deep loosening shovel, the compound deep loosening shovel and the compound deep loosening method can complete soil deep loosening and material deep loosening at the same time, The farmland cultivation process is reduced, the operation efficiency is high, and the effect and efficiency of soil improvement, water storage and moisture conservation, drought resistance and disaster reduction, and fertilizer utilization in arid and semi-arid areas are improved.

Description

technical field [0001] The invention relates to the technical field of soil subsoiling, in particular to a composite deep application subsoiling shovel and a composite deep application subsoiling method. Background technique [0002] Soil deep loosening technology is an important application technology in soil management and crop production. As one of the conservation tillage techniques, soil subsoiling has been paid more and more attention. Subsoiling can improve the tillage layer of the soil, improve the air permeability and water permeability of the soil, and achieve the purposes of water retention, drought resistance, drainage, waterlogging resistance and fertilizer retention. According to the needs of crop growth, subsoiling mostly involves different depths, different amplitudes, different effects, different soil properties, and different requirements for site preparation operations. At present, the existing soil subsoiling methods and devices mostly have certain defic...

AI Technical Summary

Problems solved by technology

At present, the existing soil subsoiling methods and devices have certain shortcomings: complex structure, cumbersome disassembly and assembly, laborious operation, single function, poor subsoiling effect, and low operating efficiency.

At present, most of the application methods of water-retaining agents and fertilizers have the following disadvantages: water-retaining agents cannot effectively fix fertilizers dissolved in water, which increases the leaching loss of soluble nutrients; water-retaining agents and fertilizers cannot be applied to crop root accumulation layers, The water and fertilizer use efficiency is reduced; the application depth of water-retaining agent and fertilizer is relatively shallow, which cannot effectively limit the leaching loss caused by irrigation (or rainfall), and increases the loss of water and soluble nutrients to a certain extent; water-retaining agent cannot expand through water absorption and regular changes in dehydration shrinkage, effectively improving the soil structure around the root system of crops, etc.
