防止蕾铃脱落,是提高棉花单产的一项重要措施。本县在大水灾的1983年,棉花普遍晚发,为了夺取丰收,在永兴重点产棉乡用“保蕾灵”进行了小面积试验和示范,证明对降低棉花蕾铃脱落有明显的效果,成桃率提高一成半,深受棉区广大干群欢迎。1984年全县七个乡共使用保蕾灵4,000余斤,推广面积8,000余亩次,占总面积16%。据两年的实际调查结果,喷施“保蕾灵”的每亩较对照增产皮棉43.3斤,每亩纯利增加54元。 To prevent the falling off of the bud is an important measure to improve cotton yield. In 1983, the county was flooded and cotton was late in the evening. In order to seize good harvest, a small-area experiment and demonstration was carried out on “Baoleiling” in the key cotton producing area in Yongxing, which proved to be effective in reducing the fall of cotton buds , Peach rate increased by 10%, by the vast majority of cadres welcomed the cotton area. In 1984, seven townships and seven townships in the county used Baolingling more than 4,000 kilos, covering an area of ​​more than 8,000 mu, accounting for 16% of the total area. According to the actual results of the two years, the output of “Bao Lei Ling” increased by 43.3 kg per mu compared with the control and the net profit per mu increased by 54 yuan.
