黄淮海平原禾豆轮作、间作对产量和水分利用效率的影响
The effects of rotation and intercropping on crop yields and water use efficiency in the Huang-Huai-Hai Plain
摘要
Abstract
[Objective]The Huang-Huai-Hai Plain is a major grain-producing region of China,where intensive cropping and limited water resources are a double whammy to sustainable agricultural production.In this study,we investigate the potential of modifying the cropping systems to address these challenges.[Method]A four-year field experiment was conducted on a typical fluvo-aquic soil in the Huang-Huai-Hai Plain in Fengqiu County,Henan Province.It consisted of five cropping systems:winter wheat-summer maize rotation(WM),winter wheat-summer soybean rotation(WS),winter wheat-summer peanut rotation(WP),winter wheat-summer maize-soybean intercropping(WMS),and winter wheat-summer maize-peanut intercropping(WMP).In each system,we measured the changes in soil water content,crop water consumption,yields of summer crops and winter wheat,and water use efficiency of the cropping systems.[Result]①The WP cropping system significantly improved soil water in both the summer crops and winter wheat seasons.Rotation and intercropping with legumes increased average soil water content by 0.7%-4.76%compared to cropping systems without legumes,with WP and WMS showing the greatest increase in soil water retention in the winter wheat season.②The WMP system reduced soil water storage consumption and water use during the crop growth period.The WS system had the highest soil water storage consumption,whereas the WMP system had the lowest.③Intercropping increased total crop yields;rotation and intercropping with legumes significantly increased the yield of winter wheat in the subsequent year,compared to systems without legumes.The average annual yield of winter wheat following legume rotation increased by 6.4%-13.88%,compared to rotation without legumes.④The WP,WMS and WMP systems significantly improved water use efficiency,while the WS system significantly reduced it.Rotation and intercropping with legumes markedly enhanced water use efficiency of subsequent winter wheat.[Conclusion]Compared with the traditional winter wheat-summer maize rotation,the WP and WMS cropping systems increased soil water content,crop yields,system economic benefits,water use efficiency and subsequent winter wheat yield.They are thus more sustainable for agricultural production in the fluvo-aquic soils of the Huang-Huai-Hai Plain.关键词
