塔里木河孔雀河中下游地区棉花膜下滴灌节水技术研究

The research on stint drip irrigation underside film for cotton production in the middle-lower reach of the Tarim river and the Peacock river

以合理利用和节约有限的水资源为目标，2002年在尉犁县孔雀农场进行了棉花膜下滴灌节水试验。得出：该区棉花膜下滴灌适宜的灌溉量为3931．5m^3／hm^2，最佳产量为皮棉2997．75kg/hm^2。与当地农民大水漫灌方式比较，节约水量8070-14070m^3／hm^2，增产皮棉747．75kg／hm^2，膜下滴灌是该区目前最节水的棉花灌溉方式之一。

The middle-lower reach of the Tarim river and the peacock river is one of the most dry and water shortage regions in our country. Above 95 % of the water resource in this area is used in irrigation for the agriculture. Irrigation method is the inundation flooding Irrigation. The water waste is seriously. The shortage of water resources limits the economy. We conducted experiments using drip irrigation underside film for cotton in 2002. The results show as following： The appropriate drip irrigation amount underside film for cotton production in this area is 3 931.5 m^3/hm^2. The optimal lint cotton yield is 2 997.75 kg/hm^2. Compared with the traditional irrigation way, this irrigation method can save 8 070-1 470 m^3/hm^2 water, increase 747.75 kg/hm^2 lint cotton. It is testified that the drip irrigation underside film is one of the most saving irrigation ways for cotton production in this area currently.
