不同耕法对土壤含水量、玉米生长发育及产量的影响
Effect of Soil Moisture and Maize Growth and Yield under the Different Cultivation Method
摘要
Abstract
The soil cultivation could the effective improvement soil physics and chemistry nature, enhance the soil moisture content and the crop yield, this article has studied the Liaoxi area maize continuous cropping different cultivation method to the soil moisture, the maize growth and the yield influence. The result indicated:influence of different cultivation method to be different differently to the soil moisture in the different time , in different cultivation method,is most obvious by an omni-directional deep pine processing effect, in the 20 ～ 30 cm soil effective plow layer is 1.29 g/cm3. An omni-directional deep pine, successive years the fall turns,successive years the ditch ridge alternately deep pine to be able to increase the maize high and increases the maize the leaf area, the yield, by an omni-directional deep pine, successive years the fall turns with the ditch ridge alternately deep loose effect is successive years most obvious, increased 13.7％ separately compared to the comparison, 10％ , 3％.关键词
