| 2000年5～8月在新疆石河子121团土壤改良实验站进行了棉花膜下滴灌需水量和灌溉制度的试验研究。结果表明，膜下滴灌条件下灌水量过多或过少均不利于高产，为了取得高产和较高的水分利用率，全生育期的耗水量应在345～380mm之间。生育期适度缺水可以提高棉花的品质。在当地气候、土壤及栽培模式下，棉花膜下滴灌的灌溉制度为全生育期灌水12～14次，灌水定额25～30mm。 |

| The field experiments were conducted at the Experimental Station of Soil Amelioration, Shehezi, Xinjiang Uygur Autonomous Region in 2000 from May to August.It is found that the excessive irrigation is not benefit to the increase of contton yield.In order to attain high yield and high efficiency of water use, the total water amount must be controlled in the range of 345mm to 380mm.The moderate water deficit in seedling stage, full water supply in bud and flower stages and properly controlling of water supply in the later stage of flower are in favor of the increase of cotton yield. The moderate water deficit can elevate the quality of cotton. It is concluded that the best irrigation pattern is 12 to 14 times of irrigation with water amount of 25mm to 30mm for each time. |
