摘　　要：水、肥是影响作物生长的两大最基本的环境因子,合理的水肥供应是作物高产高效的生理基础,如何通过有效的措施达到合理经济地利用水分和养分,对新疆棉花的可持续发展具有重要意义。通过不同年际间,北疆膜下滴灌高产示范田中灌水、施肥措施对棉花产量及产量构成特点影响的研究。结果表明,新疆滴灌棉田产量逐步提高与棉花种植密度的增加,水肥后移,增加花期以后钾的施用量等栽培措施密切相关。在蕾期—盛花结铃期增加灌水次数,减少灌水周期、时间及灌水量;结铃期到始吐期,在保证灌水次数的同时,适当减少灌水量,能明显提高全生育期的水分利用效率,有效地节约生产成本。Water,fertilizer are the most basic environmental factors in affect the growth of crops,rational and efficient water and fertilizer supply is a physiological basis of crop yield.How to use effective measures for the reasonable economic use of water and nutrients is great significance to the sustainable development of Xinjiang cotton production.Research the influence of irrigation and fertilization on yield cotton and trait of yield formation in High-yield Cotton of under-mulch-drip irrigation at North Xinjiang by different years.The results indicated that the yield cotton increased step by step was related to planting measures,which were increasing planting density,deferring irrigation and fertilization,increasing quantity of K after florescence.Increasing the times of irrigation,reducing periods,time and quantity of irrigation in bud period to flowering and boll period;To make sure the times of irrigation and reducing the quantity of irrigation in boll period to spit wadding period.They can increase the moisture utilize efficiency of full procreate obviously,and can save produce cost effectively.
