【摘要】 介绍1998年4～9月在新疆石河子炮台土壤改良试验站进行的大田棉花膜下滴灌与沟灌应用推广的试验研究情况.研究结果表明:膜下滴灌棉花的经济产量和水分利用效率两项指标分别较沟灌棉花高出18 9%和143 7%;通过经济效益分析测算,膜下滴灌棉花较沟灌棉花增收节支8155元/hm2,而且还具有一定的社会效益和生态效益.更多还原

【Abstract】 Field experiments on the popularization of mulched drip irrigation and furrow irrigation to cotton cultivation were conducted at the Shihezi Experimental Station of Soil Amelioration of Xingjiang Uygur Autonomous Region from Apr. to Sep., 1998. The result shows that the cotton yield and WUE under mulched drip irrigation are 18.9% and 143.7% higher than those under furrow irrigation. Economic benefit analysis also shows that mulched drip irrigation for cotton cultivation can save (8?155?Yuan/hm~2) as compared with furrow irrigation. Besides, mulched drip irrigation can also generate certain social and ecological benefits.更多还原
