| 中文摘要: |
| 试验于2008年在甘肃武威进行,采用水量平衡法在充分灌溉的条件下研究了石羊河流域春小麦、春玉米、制种油葵、色素辣椒、小麦/玉米带田等5种作物的需水量及需水规律,并根据作物生育期需水规律提出了适宜的灌溉制度。试验结果表明,春小麦全生育期需水量为480.5 mm,需水关键期为拔节期和抽穗开花期;春玉米需水量为569.0 mm,需水关键期为拔节期、大喇叭口期和灌浆期;制种油葵需水量291 mm,需水关键期为现蕾期和开花期;色素辣椒需水量为395.8 mm,需水关键期为坐果期和膨大期;小麦/玉米带田需水量为636.4 mm,需水关键期为小麦拔节期即玉米壮苗期、小麦孕穗期即玉米拔节期。春小麦、春玉米、制种油葵、色素辣椒、小麦/玉米带田适宜的灌水次数分别为:4次、5次、2次、5次和6次。 |

| An experiment was conducted out in Wuwei of Gansu Province in 2008. Water balance method was adopted to study the water requirement and water requirement law of spring wheat，spring maize, oil sunflower, capsicum and wheat intercrop maize, so as to give suitable irrigation program according to the growth period and water requirement law of crops. The results showed that spring wheat s water requirement was 480. 5 mm in the whole growth period, and the key imigation period appeared in jointing and heading stages; Spring maize's water requirement was 569.0 mm, and the key irmigation period appeared in shooting，trumpet and flling stages; Oil suflowver s water requirement was 291.0 mm，and the key irrigation period appeared in squaring and blooming stages; Capsicum s water requirement was 395.8 mm，and the key irrigation period appeared in fruit setting and expanding stages; Intercropped wheat and maize s water requirement was 636.4 mm，and the key irrigation period appeared in jointing and booting stages of wheat. The suitable irrigation times of spring wheat，spring maize, oil sunflower，capsicum， intercropped wheat and maize were four, five, two, five and six times，respectively. |
