摘　　要：控失肥一次基施区的棉花,营养生长与生殖生长协调好,后期健壮不早衰,比分次施用等养分普通肥区增加产量,增产幅度在4.14%-45.6%。相对普通复合肥区,施用控失肥区可以降低人工成本1/3以上,籽棉生产成本每kg减少0.0735元,试验净收入增加幅度在38.8-347.33元,示范净收入增加141.4元左右,增加了棉花种植综合效益。Cotton in the Lose - Control Fertilizer area grow steadily, the nutrients growth can coordinate with the reproductive one and their growth doesn＇ t fade in the early period. The application of the Loss - Control Fertilizer used as base can increase the production by 4. 14% -45.6% . when compared with common fertilizer,the application of Loss - Control Fertilizer can ruduce the cost of labor by 33.3% ,and ruduce the cost of reproduction by 0. 0735 yuan per kilogram cotton. In the experiment when compared with once basic application. ,the net income of the experiment increased by 38.3 - 347. 33yuan, and the demonstration increased by 141.4 yuan. The application of Lose - Control Fertilizer can improve the all - around benefit of planting cotton.
