不同微集水方式对玉米田耗水规律的影响
Effects on Soil Water Consumption of Maize Field in Differente Soil Micro-catchment Pattern
摘要
Abstract
The experiment was conduced to study the effect of unary or binary coverage of three micro-catchment patterns in comparison with the traditional cropping pattern. The results indicated that T2 (ridge and ditch mulched film) water conserved best, T3 (ridge mulched film and ditch mulched straw) was the nextbest pattern, and T1 (ridge mulched film and ditch no-mulched) was the third. In compared with the control,the volume of soil water consumption of T2, T3 and I1 decreased by 49.87 mm, 43.06 mm and 29.39 mm.and the volume of water requirement of T2, T3 and T1 decreased by 81.66 mm, 69.20 mm and 48.45 mm,the average of crop coefficient decreased by 0. 12, 0. 16 and 0. 09. Micro-catchment patterns can increase maize production and water use efficiency in varying degrees, especially T3 and T2.关键词
