Soil fertilizing and improving method for grain-grass interaction of furrows

Abstract

The invention discloses a soil fertilizing and improving method for grain-grass interaction of furrows. The soil fertilizing and improving method specifically comprises the following steps that 1, a field is leveled, furrows are dug and ridged, the ridges are high and deep, and the furrows are equal in width; 2, crops are densely planted on the ridges; 3, green manure or pasture is planted in the furrows before the crops on the ridges grow and close the rows, and grain-grass interaction is carried out; 4, when the crops on the ridges are mature and harvested, straw is applied into the furrows and mixed with the green manure or the pasture in the furrows to be returned to the field; and 5, the soil on the ridges is transferred into the furrows, the furrows are covered with the green manure and straw which are mixed and returned to the field, the furrows are continuously dug at the positions of the ridges, and ridging is carried out at the positions of the original furrows to complete interchange of the ridges and the furrows. According to the soil fertilizing and improving method for grain-grass interaction of the furrows, accurate strip-shaped soil fertilization is achieved, full-coverage improvement of cultivated land soil is achieved after ridge and ditch rotation, grain-grass interaction synergistically promotes production, the soil fertilization improvement effect is remarkable, and the crop yield and quality are improved.

Description

technical field [0001] The invention belongs to the technical field of soil fertilization and improvement, in particular to a soil fertilization and improvement method in which ridges and furrows are exchanged for grain and grass interaction. Background technique [0002] With the increase of China's population, the acceleration of urbanization, the reduction of the scale of cultivated land resources and the relative concentration of crop production areas and other factors, crop continuous cropping has become a common trend. With the increase of continuous cropping years, the crop growth condition deteriorates, the yield decreases, the quality deteriorates, and the occurrence of pests and diseases intensifies, which affects the yield and quality of crops to varying degrees. Therefore, continuous cropping obstacles have become an important factor restricting sustainable agricultural production. factor. [0003] Soil fertilization is to continuously increase soil organic matt...

Problems solved by technology

[0004] The purpose of the present invention is to provide a soil fertilization method suitable for ridge planting, ridge and furrow interchange full coverage improved soil, grain and grass intercropping synergistically promote production, to solve the problem that the improvement period of cultivated land soil fertilization is long and the effect of soil fertilization is not significant The problem
