于1987～1989年对7年生巨峰葡萄(4.5亩)进行了喷布不同浓度的矮壮素试验。矮壮素(湖南农药厂产)处理浓度为500、670、1000和2000ppm,于初花期(5月23～25日)喷布,每处理80株,重复两次。清水做对照,均设有保护行。 两年试验结果表明:①在初花期喷布矮壮素对巨峰葡萄座果率均有一? In 1987 ~ 1989, 7-year-old Kyoho grape (4.5 mu) was sprayed with different concentrations of CCC. Chlormequat (Hunan Pesticide Factory production) processing concentrations of 500,670,1000 and 2000ppm, at the beginning of flowering (May 23 ~ 25) spurting, 80 for each treatment, repeated twice. Water control, are equipped with protection line. The results of two years showed that: (1) Chlormequat was sprayed at the first flowering stage on fruit yield of Kyoho grape;
