棉田常年旋耕导致土壤犁底层变硬增厚,土壤蓄水保墒能力下降,养分在表层富集,病虫草害加重;为解决上述问题,河北省农林科学院棉花研究所“渤海粮仓”课题组提出了一项新的土壤耕作技术一土壤耕层重构,该技术是土壤耕作领域一次突破性技术创新,获得国家发明专利1项,实用新型专利1项。土壤耕层重构技术在降低土层容重、调节土壤水分供应、平衡土壤养分垂直分布、灭除
In the cotton field, the rotary plowing resulted in the soil plow hardened and thickened, the soil water storage capacity decreased, the nutrients were enriched in the surface layer, and pests, weeds and grasses increased. To solve the above problems, the Cotton Research Institute of Hebei Academy of Agriculture and Forestry “Bohai Sea Granary ” The group proposed a new soil tillage technology-soil tillage reconstruction, a breakthrough technological innovation in the field of soil tillage, which won 1 national invention patent and 1 utility model patent. Soil topsoil reconstruction technology in reducing soil bulk density, regulating soil moisture supply, vertical distribution of soil nutrients balance, eliminate
