水土保持技术,实质上是栽培技术和耕作技术一体化的研究成果。所谓一体化,是指栽培措施和耕作措施之间没有任阿矛盾,而是相互促进,相得益彰。我们的研究结果指出,要做到这一点,必须用土壤胶体物理和胶体化学的方法,找出既有利于土壤充分发挥胶体活性,又有利于全部生态因子的相互谐调,从而达到滴水归田,防早防洪的目的。办法是在表土或覆盖物中加入钾肥以及膨润土等助渗剂,来改进土壤渗透性能,杜绝土壤中碱性胶基阻碍渗透的不良效应,也可和等高垄作、地面覆盖等措施结合在一起,更好地发挥保持水土和免耕免灌等效益。
Soil and water conservation technology, in essence, is the integration of cultivation techniques and cultivation techniques. The so-called integration refers to the fact that there is no contradiction between the cultivation measures and the cultivation measures. Instead, they promote each other and complement each other. Our results point out that in order to do this, we must use the method of soil colloid physics and colloid chemistry to find out that it is conducive to the soil to give full play to colloidal activity, but also conducive to the mutual harmonization of all ecological factors, so as to achieve drip and return to the field. The purpose of early flood control. The method is to add topsoil or covering agent such as potash fertilizer and bentonite and other penetration enhancers to improve the soil permeability, prevent alkaline soil in the basement obstruct the adverse effects of infiltration, but also and contour ridge, ground cover and other measures together , To better play to maintain soil and water conservation and no-tillage and other benefits.
