| 摘 要： | 在甘肃河西灌区,对蚕豆、豌豆、大豆3种豆科作物与玉米间作下水分利用情况进行了研究,结果表明:在不同时间和氮水平下,3种豆科作物土壤水分含量变化不同。3种豆科作物与玉米间作相对于单作,不施氮条件下,蚕豆/玉米间作水分用量(WU)减少5.05%,水分利用效率(WUE)增加26.23%;大豆/玉米间作WU和WUE分别减少0.97%、23.12%;豌豆/玉米间作WU增加13.05%、WUE减少17.08%。在225 kg/hm2氮水平下,3种豆科作物与玉米间作相对于单作WU减少3.69%~7.26%,蚕豆/玉米和豌豆/玉米间作相对于单作WUE增加33.33%和23.45%,而大豆/玉米间作WUE减少12.92%。 |

| Abstract: | Effects of 3 leguminous plants intercropped with maize on water use in Hexi corridor of Gansu province were discussed.The results show that soil water content were different at two nitrogen rate and various harvest time.With no nitrogen application,water use(WU) by faba bean/maize and soybean/maize intercrops relative to sole crops were decreased by 5.05% and 0.97%,and pea/maize intercrops relative to sole crops were increased by 13.05%,respectively.Water use efficiency(WUE) by faba bean/maize intercrops re... |
