摘要: 比较研究了垄膜沟灌和覆膜漫灌模式下不同水分处理对制种玉米生产效益的影响,旨在为河西走廊玉米制种高效节水栽培模式提供依据。设置两种栽培模式下的8个不同水分处理水平,采用AHP层次分析法与熵权法构建TOPSIS数据模型,通过该数据模型将制种玉米的农艺性状与经济效益综合分析,并选出最优栽培模式方案。结果表明,根据相对接近度处理F3排名最前,意味着该处理在不同灌溉模式及水分处理下所产生的经济效益最好,是所有处理中的最优方案;其次是处理F2、FC、F1、T2、T3、T1、TC。在河西走廊制种玉米覆膜漫灌的栽培模式下,整个生育期灌水7次,灌水定额50 mm,灌溉定额350 mm,3段生育期水分控制为80%、60%、60%时,在所有试验处理中经济效益最大化。因此,覆膜漫灌玉米比垄膜沟灌玉米用水量少,产量高且效益更好。

Abstract: The paper comparatively studied the effects of different water treatments on production benefits of maize under ridge film furrow irrigation and mulch film flood irrigation to provide a basis for establishing high efficiency and water-saving cultivation mode for maize production in Hexi Corridor. In this field experiment, eight different water treatment levels were set under two cultivation modes. At the same time, TOPSIS model was constructed based on the AHP analytic hierarchy method and the entropy weight method, and the optimal cultivation mode plan was obtained by analyzing the agronomic characteristics and economic benefits of seed production maize with this model. The results showed that treatment F3 ranked first, followed by treatment F2, FC, F1, T2, T3, T1, and TC according to the relative proximity, suggesting that the best economic benefits were acquired in treatment F3 under different irrigation modes and water treatments. Under the maize production model of film mulching flood irrigation in Hexi Corridor, the maize was irrigated 7 times during the whole growth period, with the irrigation quota per time of 50 mm and the total irrigation quota of 350 mm, and the water control in the three growth periods was 80%, 60%, and 60%, so the economic benefit was maximized in all treatments in the experiment. In a conclusion, compared with ridge-film furrow irrigation, film-mulched flood irrigation was less in irrigation amount, higher in maize yield and better in benefits.
