水氮耦合对膜下滴灌棉花生长及产量的影响
Effects of Water-Nitrogen Coupling on Growth and Yield of Cotton under Mulch Drip Irrigation
摘要
Abstract
[Objective] To study the effects of water and nitrogen coupling on the growth and yield of cotton under mulch drip irrigation in Shihezi area of Xinjiang,pot experiment was designed.[Method] Nongfeng No.133,an early-maturing variety commonly cultivated in the region was used as the test material under drip -irrigated condition in a pot experiment that was completely randomized with two-factor and three-level treatments.Three irrigation levels were set:4,350,5,250 and 6,150 m3/hm2 (labeled W1,W2,W3) and three nitrogen application levels were set:300,500,700 kg/hm2 (labeled F0.6,F1.0,F1.4).The effects of different treatments on plant height,leaf area index,dry matter accumulation and yield of cotton were analyzed and measured.[Result] The results showed plant height and leaf area index were increased with the increase of irrigation amount under the condition of mulch drip irrigation.At the same irrigation level,with the increase of the amount of nitrogen,the index showed that the trend increased at first and then decreased and the maximum value arrived at F1.0,however,excessive fertilization inhibited the growth of cotton to some extent.[Conclusion] Based on the effects of water-nitrogen coupling on the growth of drip-irrigated cotton,water and nitrogen fertilizer were recommended to be applied in the amounts of 5,250 m3/hm2 and 500 kg/hm2,respectively in the Shihezi area in order to achieve the highest yield.关键词
