新疆奇台县滴灌冬小麦节水增产关键技术

Key Technology of Drip Irrigation Winter Wheat Water-saving and Yield-increasing in Qitai County,Xinjiang

通过对奇台县小麦滴灌技术现状及节水增产关键技术的探讨,介绍小麦滴灌节水增产原因和节水增产关键技术并提出奇台县滴灌冬小麦高产栽培技术要点：播种适期为9月15～25日;选用早熟、高产、优质的冬小麦品种;滴灌带滴头间距宜为30 cm,滴头设计流量3.2 L/h,滴管带铺设间距为60 cm;冬小麦全生育期施尿素600 kg/hm2,灌水量4 200 ～4 500 m3/hm2.这可为奇台县小麦滴灌技术的大面积推广示范提供参考.

Through investigation on wheat drip irrigation technology status in Qitai County and key technology of water-saving and yield-increasing,the yield increasing reasons were introduced and cultivation techniques were put forward：sowing suitable period of September 15 to 25; selection of precocious,high-yield,high-quality winter wheat varieties ; drip tape should be used dripper spacing 30 cm,dripper design flow 3.2 L/H,with the laying of dropper spacing 60 cm.Winter wheat urea 600 kg/hm2,irrigation volume 4 200-4 500 m3/hm2,which will provide a reference for a large area of the promotion of drip irrigation technology in Qitai.
