| 摘 要： | 在降雨、灌溉水量和前期土壤特性一定的情况下，对玉米在喷灌、滴灌、渗灌3种灌溉方式下的土壤水分变化特性和玉米生育特性进行了试验研究，分析了各种灌溉方式下玉米的生长特性和玉米地土壤水分的变化规律。试验结果表明：渗灌的节水增产效果最好，产量比滴灌增加1．3％，水分生产率由2．64kg／m^3提高到2．68kg／m^3；比喷灌增加6．3％，水分生产率由2．52kg／m^3提高到2．68kg／m^3。

| Abstract: | Under specific rainfall, irrigation quantity and initial soil conditions, the variation characteristics of soil moisture and growth characteristic of maize under three different irrigation techniques, as sprinkler irrigation, drip irrigation and infiltration irrigation, were studied through experiment. The experiment results indicated that the effect of water saving and yield increase of infiltration irrigation was the best. Compared with drip irrigation and sprinkler irrigation, its yield increased by 1.3% and 6. 3%,while water use efficiency increased from 2.64 kg/m^3 and 2.52 kg/m^3 to 2.68 kg/m^3 ,respectively. |
