Soil-layer displacement method and soil-layer displacement plough

Abstract

The invention relates to a soil layer displacing method and a soil layer displacing plow. The soil layer displacing method comprises the following steps: firstly, plowing a plowing layer trench with the plowing layer depth; turning and covering a plowed plowing layer furrow at one side of the plowing layer trench to prepare for the subsequent soil layer displacing operation; secondly, plowing downwards in the plowed plowing layer trench, and plowing, turning and covering the soil in a subsoil layer of the trench on the plowing layer furrow to form a deep trench; and finally, turning and covering the soil of a plowing layer at the other side adjacent to the plowing layer in the deep trench to form a new plowing layer trench. The soil layer displacing method and the soil layer displacing plow have the advantages that: a 'fatigue soil layer' of a surface layer and a 'good soil layer' of a subsurface layer are displaced, and the aims of relieving the 'fatigue soil layer', reducing the harm of residual pesticide and improving the yield of crops are achieved. The invention provides powerful technical support for achieving the protection and utilization of black earth, the sustainable development of agriculture and mechanical improvement of soil in a large area.

Description

technical field [0001] The invention relates to a soil layer replacement method and a soil layer replacement plow, which are used for mutual replacement of the soil of the plowed layer and the sub-plowed layer (core soil layer) of cultivated land. Background technique [0002] Heilongjiang Province is the main soybean production base in my country, with an annual planting area of ​​about 3.6 million hectares. Especially in the area north of 47° north latitude, the soybean planting area accounts for more than 85% of the arable land area. The phenomenon of continuous cropping of soybeans is very common, and the obstacles to continuous cropping are serious. The general yield loss is 10%-30%, or even disappears. After soybean cropping, one is to cause severe pests and diseases, and the other is to cause self-poisoning. Soybean root exudates affect the dynamics of soil microbial flora and inhibit the growth of the next crop of soybeans. The third is that continuous cropping lead...

Problems solved by technology

Solve the problem that the existing technology cannot replace the upper and lower soil layers and the overlapping of the soil formation during the flipping process, replace the plow layer soil in the "fatigue" state to the bottom layer, and perform "three-dimensional leisure", so as to reduce continuous cropping obstacles, Reduce the harm of residual pesticides to subsequent crops and increase the effect of crop yield
