Tillage tool for implementing moisture and fertilizer retention performance of shallow tillage layer and method of using tillage tool to establish shallow tillage layer

Abstract

The invention discloses a tillage tool for implementing moisture and fertilizer retention performance of a shallow tillage layer and belongs to the technical field of agricultural machinery. The tillage tool comprises a beam frame, a suspension frame, a transmission mechanism, a groundbreaking mechanism, a discharge mechanism, an earthing mechanism and a suppressing mechanism; the beam frame is connected with a tractor through the suspension frame; the output power of the tractor is connected with the groundbreaking mechanism and the discharge mechanism respectively through the transmission mechanism, the groundbreaking mechanism is formed by arranging a large groundbreaking cutter head on a rotating shaft, the large groundbreaking cuter head corresponds to the position of a seedling strip, an earthing shovel of the earthing mechanism and a discharge shovel of the discharge mechanism are in one-to-one correspondence with the large groundbreaking cutter head, a digging groove is formed through soil broken by the large groundbreaking cutter head, the discharge shovel is used for ditching and discharging materials, and the earthing shovel is used for earthing to have fertilizer buried underground. By the arrangement, the fertilizer can be discharged underground to be mixed with the soil to form the shallow tillage layer, the purposes of moisture and fertilizer retention and establishment of the shallow tillage layer are realized, and the soil is prevented from desertification and salinization.

Description

Technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a tillage machine tool and a method thereof for realizing the performance of water and fertilizer conservation in a submerged layer. technical background [0002] At present, my country's agricultural sector is facing serious soil degradation problems, and soil desertification and salinization are the main causes of soil degradation. After soil desertification, the nutrients and water in the soil are lost too quickly, which cannot provide a good guarantee for crop growth. Even if nutrients and irrigation water are artificially applied, they will be lost due to soil desertification and cannot be well preserved in the soil for crop growth. needed. A large amount of salt accumulated in saline-alkali soil will cause a series of soil physical and chemical properties to deteriorate: sticky structure, poor ventilation and water permeability, high bulk density...

AI Technical Summary

Problems solved by technology

After soil desertification, the nutrients and water in the soil lose too fast, which cannot provide a good guarantee for crop growth. Even if nutrients and irrigation water are artificially applied, they will be excessively lost due to soil desertification, and cannot be well preserved in the soil for crop growth. required

A large amount of salt accumulated in saline-alkali soil will cause a series of soil physical and chemical properties to deteriorate: sticky structure, poor ventilation and water permeability, high bulk density, low fertility, slow nutrient release, seriously affecting the emergence and normal growth of crops, especially unfavorable The growth of the root system and the absorption and utilization of water and nutrients in the soil by the root system lead to physiological drought in the plant and inhibit growth

Due to the existence of the above problems, the sustainable development of agriculture has been adversely affected
