摘要
阐述了棉花膜下滴灌技术宽膜覆盖“一管四行”与“二管四行”两种毛管滴灌带布设方式。试验研究结果表明 ,膜宽 1 .1 m,棉花行距为 2 0 cm/ 40 cm/ 2 0 cm,“一管四行”可满足棉花生长发育各阶段对土壤水分的要求 ,且比“二管四行”节省投资 960元 / hm2 ,年运行费节约 75 0元 / hm2 ,产量提高 4.0 % ,适宜在新疆广大棉区大面积推广。
Drop irrigation technique of cotton under plastic film covering '1 pipe 4 lines' and '2 pipes 4 lines' of the two drop irrigation tape disposition pattern was expounded. Experimental research result showed that the film with width of 1.1 m, 20 cm/40 cm/20 cm, '1 pipe 4 lines' could completely satisfy the requirement of cotton in each growth period for soil moisture. The '1 pipe 4 lines' then '2 pipes 4 lines' could save investment 960 yuan/hm 2 of investment and 750 yuan/hm 2 of annual operating cost, and increase yield by 4.5%, which is advised to be popularized in larger areas of cotton growing region in Xinjiang.
