棉花环般技术是根据果树环剥原理提出的一项棉花控长、促铃、增产新技术。具有操作简单、成本低廉等优点。经对比试验，平均比对照增产15％左右。1.环嵌时期选择适宜的环嵌时期是决定环嵌效果的重要因素。环嵌时期主要取决于棉花生长发育的时期，长江中下游棉区生长发育正常的 Cotton ring-like technology is based on the principle of fruit ring girdling put forward a long cotton, boll, increase production of new technologies. Has the advantages of simple operation, low cost and so on. The comparative test, an average yield of about 15% more than the control. 1. Cyclocnea epoch selection The appropriate epilogue is an important factor in determining the embedding effect. Central embedded period mainly depends on the period of cotton growth and development, cotton growth and development of the middle and lower reaches of the Yangtze River normal
