坡耕地的水土流失,直接影响着农业生产的发展,而耕作方法不合理,是破坏土壤团粒结构,引起土壤板结,促成土壤侵蚀,地力减退,粮食产量降低的主要原因之一。为探索保土增产的耕作方法,伊通县景台水土保持试验站,于1983～1987年进行了垅作免耕法和传统的垅作多耕法对比试验。 试验采用的垅作免耕法,是将选好的作物、种子,直接播种在已经整好地的垅上,实行药剂灭草,不翻、不耙、不中耕,一次播好种,秋后收割。试验表明,垅作免耕法具有较好的保水、保土、保肥和提高土地生产力等作用。
Soil and water loss in sloping arable land directly affects the development of agricultural production. However, the cultivation method is unreasonable. It is one of the main reasons for destroying soil aggregate structure, causing soil compaction, contributing to soil erosion, reducing soil fertility and reducing grain yield. In order to explore the tillage method of increasing soil production, Yitong County Jingtai Soil and Water Conservation Experimental Station carried out the tillage-no-tillage and traditional tillage-tillage comparison experiments from 1983 to 1987. The no-tillage method used in the experiment is that the selected crops and seeds are planted directly on the already-fine ground, and pesticides are used to extinguish the grass, without turning, without raking, without cultivating, once sowing good seeds, and after autumn Harvest. Experiments show that tillage tillage has good water retention, soil conservation, fertilizer and improve land productivity and so on.
