石羊河流域甜菜机械穴播膜下滴灌栽培技术

提高水资源利用率已成为关系甘肃河西灌区可持续发展的战略任务,作为甘肃甜菜产区的石羊河流域水资源紧缺,推行甜菜滴灌可起到节水、稳产、增产效果,生产上有较强的实用性和较好的推广价值.甜菜机械穴播膜下滴灌栽培技术实现机械覆膜、打孔、播种、铺设滴灌带一次性作业,全生育期滴水7～9次,每次300～ 500m3/hm2左右,总用水量3800 ～ 4200 m3／hm2,节水20％以上.

Drip irrigation under mulch cultivation techniques of sugar beet machinery bunch planting in the Shiyang river basin

Improving the utilization rate of water resources has become strategic task of Gansu sustainable development in Hexi irrigated area. Water Resources is shortage in Shiyang river basin, Gansu sugar beet growing areas, and implementation of Sugar beet irrigation can play water saving, stable, yield increasing effect. The technology has a strong practicability and popularization value in the production. It is machine mulching, punch, seeding, laying of drip irrigation tape disposable operation that is drip irrigation under mulch cultivation techniques of sugar beet machinery bunch planting, and, during the whole growth period, it need drop water 7 - 9 times , every time 300 - 500m3/hm2, total water consumption of 3800 - 4200m3 / hm2, saving more than 20%.
