摘  要：
南疆棉花生产迅速发展，肥料投入也不断增加，肥料投入量应该有个限量，应适应棉花的产量水平，还要考虑土壤供肥能力的变化，南疆土壤已不能再说是缺磷少氮的状况了。缺氮的问题没有得到根本的改观，应是第一位的，而磷的问题有了很大的好转，适当调低磷氮比值，减少磷肥的投入量，只会提高肥料的经济效益，而决不会影响棉花的产量。地膜棉前期易旺长，后期易早衰，通过施肥与灌水，化调密切协调配合，控制前期的旺长，防止后期的早衰，是地膜棉花高产施肥的核心。，

摘  要：
With rapid cotton production in the South of Xinjiang , fertilizer imput is keep-ing on the rise. Fertilizer imput should have alimit, corresponding to yield level, and the va-riety in fertilizer -supplying ability of the soil had to be taken into account. The soil in theSouth is no longer short of phosphorus and nitrogen. Nitrigen's shortage hasn't beenfoundamentally improved and it is still a No. 1 problem whearas phosphorus lack improvedgreatly. Properly lowering theratio of phosphorus and nitrigen will only improve the eco-nomic effeciency of fertilizer with no effect cotton yield. Mulch farming cotton tend to growluxuriantly in early stage and become premature senescene in late stage. Thus the kernel ofhigh field fertilizer application in mulch farming cotton is to control the luxuriant growth inearly stage and senescene in late stage by means of fertilizer application and watering com-bined with chemical adjustment.
