Description

A pneumatic subsoiler

technical field

The invention relates to a machine for loosening soil and deepening the thickness of a plow layer, in particular to a pneumatic subsoiler, which belongs to the field of agricultural machinery.

Background technique

Soil subsoiling refers to the use of a subsoiler to loosen the plow layer 5 to 15 cm below the plow layer, loosen the soil and deepen the thickness of the plow layer. Soil subsoiling is an indispensable mechanized operation item to obtain high yield of crops, and an important technology of soil cultivation, which has been paid more and more attention at home and abroad.

Soil deep loosening technology can break the plow bottom layer and deepen the plow layer thickness. The existence of the bottom layer of the plow prevents the root system of the crops from piercing through, but can only curl and grow above the bottom layer of the plow; the barrier of the bottom layer of the plow prevents precipitation from infiltrating and forms surface runoff, causing serious soil erosion; when the surface is dry and lacks water, The bottom layer of the plow blocks the rise of soil moisture in the lower layer, which cannot supply the growth of crops. Soil subsoiling can break the hard plow bottom layer, improve soil permeability, increase the thickness of the plow layer, increase the water holding capacity in the field, and create good soil conditions for the normal growth of crops.

The pneumatic soil subsoiling technology can not only improve the physical and chemical properties of the soil, improve the lodging resistance of crops, but also improve the ability of soil water storage and moisture conservation. Pneumatic soil subsoiling technology improves the three-phase ratio of soil solid, gas and liquid substances through subsoiling, strengthens the survival and reproduction ability of soil microorganisms, accelerates the mineralization and weathering of organic matter, improves soil structure, enhances soil adsorption capacity, and improves soil fertility ; Because the bottom layer of the plow has a flaky structure and the soil layer is firm, this will lead to a decrease in the vertically distributed roots of the crops and an increase in the horizontally distributed roots. The deep mineral nutrients are difficult to be utilized, and the lodging resistance of the crops also declines. Pneumatic subsoiling can increase the depth of the plow layer, increase the water permeability and oxygen content of the soil, block the loss of upper and lower water, increase drought resistance and flood discharge, water storage and moisture conservation, and is conducive to the deep rooting of crops, and finally achieve lodging resistance; the soil is covered After deep loosening, the soil can absorb more rainwater, establish a good "soil reservoir", reduce surface runoff, avoid soil erosion, and store more rainwater to achieve the effect of water storage and moisture conservation, and to protect the agricultural ecological environment.
