豫西旱作麦区灌水对旱地小麦产量和水分利用效率的影响
Effects of Irrigation on Yield and Water Use Efficiency of Dryland Wheat in Yuxi Dryland Wheat Area
摘要
Abstract
The performance of the main popularized wheat varieties under different irrigation conditions was analyzed comprehensively,in order to provide theoretical support for wheat variety selection and water optimization management under Yuxi dryland wheat ecological conditions.The results showed that yield performance:The yields of'Luohan 6'and'Luohan 7'were the highest when irrigated at jointing stage.They were 3.33 ％-33.16 ％ higher than those of irrigated at jointing stageand flowering stage,or no irrigation.The yields of'Luohan 8'when irrigated at jointing stage and flowering stage was the highest,which was 6.99％-44.45 ％ higher than that of irrigated at jointing stage and no irrigation.The water use efficiency performance of'Luohan 6'irrigated at jointing stage and no irrigation were 31.08％ and 18.20％ higher than that irrigated at jointing stage and flowering stage respectively.The water use efficiency performance of'Luohan 7'with no irrigation was 13.88％ and 38.99％ higher than that irrigated at jointing stage and flowering stage respectively.The water use efficiency performance of'Luohan 8'irrigated at jointing stage were 5.48％ and 12.95％ higher than that irrigated at jointing stage,flowering stage and no irrigation respectively.In order to achieve a win-win situation of high yield and high water use efficiency,water management for different varieties should be optimized.关键词
