1987-1988年,我们进行了巨峰葡萄幼果期(5月21日)喷布不同浓度PP333对其座果及含糖量影响的试验。共设四个浓度处理;40、80、100和120ppm,以喷清水为对照。以8-10个果穗为一个处理,重复三次。结果以80ppm处理效果最佳。不仅座果率(75.91%)有极显著的提高(对照仅55.74%),而且产
1987-1988, we carried out the Kyoho grapes young fruit period (May 21) sprayed with different concentrations of PP333 on its fruit and sugar content of the experiment. A total of four concentrations of treatment; 40,80,100 and 120ppm, spray water as a control. Take 8-10 ears as a treatment, repeat three times. The result is 80ppm best. Not only the fruit set rate (75.91%) had a very significant increase (control only 55.74%),
