摘要
为改善小麦、玉米周年丰产水肥利用效率,保障农业可持续、绿色健康发展,从品种选择、播收期调整、秸秆还田技术升级、水肥运筹途径优化以及耕作方式转变方面概述并探讨了小麦、玉米周年丰产水肥高效利用调控途径,各种方式均可改善水肥利用效率,且各具特点。然而,小麦、玉米产量提高以及水肥利用效率的改善受多种因素影响,在实际生产中,应结合降雨状况,根据土壤水、肥含量,视作物长势和需水用肥规律,合理综合利用各项措施,实现小麦、玉米周年丰产水肥高效利用。
In order to improve the utilization efficiency of water and fertilizer for annual high yield of wheat and maize and ensure sustainable,green and healthy development of agriculture,this paper summarized and discussed the ways of high-efficiency utilization of water and fertilizer in wheat and maize annual high-yield from the aspects of variety selection,sowing and harvest time adjustment,technical upgrading of straw returning to field,optimization of water and fertilizer operation ways and transformation of cultivation methods.All kinds of methods could improve the utilization efficiency of water and fertilizer,and each had its own characteristics.However,the yield increase of wheat and maize and the improvement of water and fertilizer use efficiency were affected by many factors.In actual production,according to the rainfall condition and the content of soil water and fertilizer,depending on crop growth,water and fertilizer requirement,comprehensive and rational utilization of various measures to realize high-efficiency utilization of water and fertilizer for annual high yield of wheat and maize.
