棉花播种前,需要认真做好备播工作,为一播保全苗,夺高产,创造条件。一、施足底肥,培肥地力这是棉花创高产的基础。一般计划亩产皮棉100公斤左右,需亩施优质圈肥2000～3000公斤,饼肥50～75公斤,并根据土壤肥力,增施尿素5～7.5公斤,磷肥30～50公斤,钾肥10～15公斤和适量微肥做底肥,结合耕翻一次施入。麦套棉种麦时底肥施的不足,有预留大套行的。播前结合耕翻整地,应适当补施一定数量的有机肥和化肥;没有留套种行的,无法补施底肥,可在收麦后及时补施,为棉花夺高产创造条件。
Cotton sowing, need to do a good job in preparation for sowing, for a broadcast security seedlings, winning high yield, create conditions. A Shi Shi enough fertilizer, fertility fertility This is the basis for a high cotton yield. The general plan is to produce about 100 kg of lint per mu and need to apply 2000-30,000 kg of high-quality circle fertilizer and 50-75 kg of cake fertilizer per acreage. According to soil fertility, 5-7.5 kg of urea, 30-50 kg of phosphate fertilizer and 10-15 kg of potash fertilizer Appropriate amount of fertilizer to make the base fertilizer, combined with plowing into a time.

Combined with tillage before sowing, should be appropriate to make up a certain amount of organic fertilizer and fertilizers; did not stay in kind of line, can not make up the base fertilizer, fill the wheat timely replenishment for the cotton to win the high yield to create conditions.
