| 摘 要： | 采用连续5a的田间定位试验资料，研究了洛阳地区休闲期4种不同耕作方式对冬小麦农田土壤水分变化、水分利用效率及作物产量的影响。结果表明：休闲期不同耕作方式对冬小麦播种前底墒具有明显的影响，与传统耕作方式相比，免耕和深松覆盖处理可以显著增加土壤含水率，具有良好的保墒作用；各处理以深松覆盖作物产量和水分利用效率最高，其次为免耕处理，深翻处理效果较差。因此，洛阳地区采用深松覆盖保护性耕作方式比较有利。

| Abstract: | Based on the data of continuous field plot experiments for five years in Luoyang,the influence of four different tillage practices,namely reduced tillage(RT),no-tillage(NT),subsoiling(ST) and conventional tillage(CT) on the soil moisture,water use efficiency(WUE) and crop yields of winter wheat was studied.The results showed that the soil water content before sowing was obviously improved by the no-tillage and subsoiling,compared to that by the conventional tillage.According to the yield and WUE,treatments could be ranked from highest to lowest in turn as follows: ST,NT and RT.Therefore,we concluded that the subsoiling should be adopted in Luoyang area. |
