为了探讨高寒地区少耕法的改土增产效应,我们于1978—1983年在本所的暗棕壤上进行二种轮作方式,二种耕法(少耕与连翻)的对比试验。试验结果总结如下。一、设计与方法土壤特性质地粘重,透水性差,耕性不良,适耕期短,土壤冷浆,冻结期长达十个月,冻层二米半左右,春季化冻晚,犁底层滞水,土壤温度上升较慢。在土壤性能上表现出
In order to explore the effect of reducing tillage and increasing yield in the alpine region, we conducted two kinds of cropping patterns and two tillage methods (contrasting tillage with tipping over) on dark brown soil from 1978 to 1983. The test results are summarized as follows. First, the design and methods of soil characteristics sticky texture, poor water permeability, poor tillage, short adaptability, soil slurry, the freezing period of up to ten months, frozen layer about two and a half, frozen in the spring late, plow bottom stagnant water , Soil temperature rises slowly. Performance in soil
