利用当地生产中主推小麦品种在不同灌水处理条件下的表现,分析豫西旱作麦区生态条件下,小麦品种选择和水分优化管理,以期为豫西小麦生产中品种选择、水分优化管理提供理论支撑。结果表明:产量表现,洛旱6号和洛旱7号以灌拔节水处理为最高,较灌拔节水+开花水处理和不灌水处理增产3.33%~33.16%;洛旱8号以灌拔节水+开花水处理最高,较灌拔节水处理和不灌水处理增产6.99%~44.45%。水分利用效率表现,洛旱6号灌拔节水处理和不灌水处理较灌拔节水+开花水处理提高了31.08%和18.20%;洛旱7号不灌水处理较灌拔节水处理和灌拔节水+开花水处理提高了13.88%和38.99%;洛旱8号灌拔节水处理较灌拔节水+开花水处理和不灌水处理提高了5.48%和12.95%。因此,应针对不同品种优化水分管理,以达到高产量和高水分利用效率双赢。 Based on the performance of main wheat cultivar under different irrigation treatments in local production, the wheat variety selection and water management were analyzed under the ecological conditions of drought-cropping wheat in west Henan Province, in order to provide the theory for the variety selection and water optimum management in wheat production in western Henan. support. The results showed that the yield was higher in Luohan 6 and Luohan 7 than in irrigation and irrigation, which increased 3.33% -33.16% compared with irrigated and irrigated with irrigated and irrigated, + The highest flowering water treatment, compared with irrigating irrigation and irrigating treatment yield 6.99% ~ 44.45%. Water use efficiency of Lohan 6 increased by 31.08% and 18.20% compared with irrigated and irrigated irrigated and irrigated irrigated irrigated and increased by 31.08% and 18.20% The flowering water treatment increased by 13.88% and 38.99% respectively. The irrigation and water-saving treatment of No.6 Daohan increased by 5.48% and 12.95% compared with irrigating and irrigating. Therefore, water management should be optimized for different varieties in order to achieve a win-win situation of high yield and high water use efficiency.
