Title: Effect of Different Tillage on the Dynamic Change of Leaf Area after Anthesis and Yield of Spring Wheat
Abstract:Compared with the conventional tillage,the dynamic change of the leaf area index and yield of spring wheat in different tillage(no tillage with corn stubble,no tillage with no stubble,no tillage with ...Compared with the conventional tillage,the dynamic change of the leaf area index and yield of spring wheat in different tillage(no tillage with corn stubble,no tillage with no stubble,no tillage with wheat stubble)were studied in this paper.Results showed that the maximum of leaf area index was on the 7th day after anthesis of spring wheat in different tillage,the maximum of LAI was between 3.4 and 5.1.The LAI varied with tillage,no tillage with wheat stubbleno tillage with no stubbleno tillage with corn stubbleconventional tillage;A significantly positive correlation existed between yield and LAI after anthesis of spring wheat in different tillage.The yield of no tillage with wheat stubble,that of no tillage with no stubble and that of no tillage with corn stubble were higher than that of conventional tillage and were inceased by 44.89%,33.40% and 14.58% respectively,compared with conventional tillage.The yield of spring wheat in different tillage showed:no tillage with wheat stubbleno tillage with no stubbleno tillage with corn stubbleconventional tillage.There was obvious difference among the yield of different tillage at 0.05 level.Read More
