Abstract:

Abstract: 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.
