耕作方式对土壤理化性状及夏玉米生长发育和产量的影响
Effect of Tillage Methods on Soil Physical and Chemical Properties, Growth and Grain Yield of Summer Maize
摘要
Abstract
The objective of this experiment was to study the effects of soil tillage methods on soil physical and chemical properties ,summer maize growth and grain yield ,and to provide a scientific basis for improving soil struc-ture and grain yield in northern areas of Huang-Huai-Hai region .This experiment contained four tillage styles which were sub-soiling,plowing tillage,alternate year sub-soiling and rotary tillage.The results showed that sub-soiling,al-ternate year sub-soiling and plowing tillage could significantly reduce the soil compactness at 10 cm underground and deeper;improved the soil moisture content at different growth stages ,the effect was most prominent between 20 cm to 40 cm soil layer;increased the soil potassium content′s availability between 20 cm to 60 cm soil layer;helped to maintain leaf area index at middle and later filling stages and dry matter accumulation increased 7.79%-18.09%;and increased maximum and average filling rate ,grain yield per hectare increased 4.1%-9.3%.Sub-soiling and al-ternate year sub-soiling had no significant difference between them .As far as high-yield and energy saving were con-cerned in the experiment ,the most appropriate treatment for recommendation was the alternate year sub -soiling.关键词
