1988、1989、1990连续3年于葡萄盛花期,对3年生巨峰葡萄喷布50、25和12.5 ppm复合防落素,以喷清水为对照。结果不同浓度处理,均造成新生枝叶畸形,着穗率下降,产量锐减、品质降低。浓度越大,危害越严重。因此认为葡萄生产不可使用复合防落素。葡萄不可喷用复合防落素@陈炳国$湖?
1988, 1989, 1990 for 3 consecutive years in the grape flowering period, the spike of 3-year-old Kofu spray 50,25 and 12.5 ppm composite anti-infectives, spray water as a control. The results of different concentrations of treatment, are caused by new branches and leaves deformity, the ear rate decreased, the output dropped sharply, lower quality. The greater concentration, the more serious harm. So that grape production can not use composite anti-PC. Grapes can not be sprayed with a composite anti-PC @ Chen Bingguo $ Lake?
