A Brief Talk on Mechanism and Effect of Soil Conservation Farming on Chernozem Land in Heilongjiang Province

水土保持耕作措施对于防治水土流失、促进农业增产具有明显的作用。黑龙江省水保科研机构在黑土区多年来研究推广的横坡垄作、垄作区田、少耕免耕、间混作、深松耕法、鼠道耕法等措施 ,投资少 ,见效快 ,适宜进一步推广。若将耕作措施与植物措施、田间工程措施科学配置 。

The tillage practices of soil and water conservation have notable effects on preventing and controlling soil and water loss and increasing the output of crops. The measures of strip ridge culture, contour check, little and non-tillage, deep digging, inter-cropping and etc. that are studied and popularized for years on chernozem region by Helongjiang Provincial Scientific Research Institute of Soil and Water Conservation have the advantages of less investment and quick benefits.
