新疆棉田薄壁边缝式滴灌带毛管布置方式的研究

Research of Arranging Way for Hair Tube of Thin Wall and Side Opening Type Dropping Belt

采用新型薄壁边缝式滴灌带,在新疆不同土壤条件下进行不同方式的配置,研究分析了不同配置方式下对棉花产量、节水效果、成本效益等的影响,结果表明:在砂壤土上深埋式滴灌(埋深35 cm)可显著提高棉花籽棉产量,提高水产比和水效益,降低成本,增加利润,提高经济效益。浅埋式滴灌可明显降低成本,但节水效果和增产效果较差,在砂壤土上的应用须慎重。

This paper studies and analyses the effect of new thin wall and side opening type dropping belt to cotton yield, stanza water result and cost efficiency at different soil condition and different install type. The result expresses that deep sub-surface type drop irrigation in sand soil (under ground 35 cm) can increase cotton yield,marine products ratio, the proformance, profits and decline lower cost obviously. Although shallow sub-surface can lower cost greatly, the stanza water result and the result of boosting production is worse, so we should pay more attention to using drip irrigation in sand soil.
