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。
A new type of thin-wall edge-drip irrigation tape was used to carry out the disposition in different ways under different soil conditions in Xinjiang. The effects of different arrangement modes on cotton yield, water saving effect and cost-effectiveness were analyzed. The results showed that on the sandy loam soil Deep-drip irrigation (depth of 35 cm) can significantly increase the cotton seed cotton yield, improve the ratio of aquatic products and water, reduce costs, increase profits and increase economic benefits. Shallow drip irrigation can significantly reduce costs, but the water saving effect and the yield is poor, the application of sandy loam should be careful.
