干旱区滴灌多作物需水量及灌溉制度试验分析

Experimental Analysis of Drip Irrigation Multi Crop Water Requirement and Irrigation System in Arid Area

以膜下滴灌为主模式的灌溉技术在干旱新疆灌区大面积应用,针对滴灌区多种作物灌溉制度尚未系统建立应用问题,该文基于先进的地下廊道式测坑防雨棚测验设施,采用灌水定额单因素4水平,随机区组田间灌溉试验方案,系统性同步实施滴灌12种作物需水量及灌溉制度试验,结果表明:春麦需水量和灌溉用水定额为412 mm、390 mm;旱稻为829 mm、933 mm;谷子为539 mm、573 mm;土豆为560 mm、510 mm:大豆为559 mm、557 mm;油菜为469 mm、533 mm;葵花为515 mm、530 mm;甜菜为492 mm、515 mm;打瓜为510 mm、467 mm;蕃茄为533 mm、519 mm;胡萝卜为468 mm、486 mm;苜蓿为608 mm、570 mm,试验分析结果为灌区节水灌溉定额管理提供技术支撑。

The irrigation technology with the main mode of drip irrigation under the film is applied in the arid Xinjiang irrigation area. The irrigation system of a variety of crops in the drip irrigation area has not been systematically established. This paper is based on the advanced underground corridor type test pit test shed test facilities, using the irrigation quota single factor 4 levels and the random area group field irrigation experiment scheme. 12 kinds of crop water demand and irrigation system test were carried out synchronously. The results showed that the quota of water demand and irrigation water was 412 mm and 390 mm;dry rice was 829 mm and 933 mm;millet was 539 mm and 573 mm;potatoes were 560 mm, 510 mm: soybean was 559 mm, 557 mm;rape was 469 mm, 533 mm;sunflower flower was 515 mm and 530 mm;beet is 492 mm and 515 mm;melon is 510 mm and 467 mm;tomato is 533 mm and 519 mm;carrot is 468 mm and 486 mm;alfalfa is 608 mm and 570 mm. The experimental analysis results provide technical support for water saving irrigation quota management in irrigation area.
