通过多年、多点试验，研究了ＣＰＰＵ促进猕猴桃果实增大的效果。结果表明：５－４０ｍｇ·１￣（－１）的各种浓度的处理都明显地增大了猕猴桃的果实，效果异常突出，增长幅度在２０％－１９０％之间。１０－３０ｍｇ·１￣（－１）处理效果之间似乎没有显著差异，推荐最适使用浓度为１０－２０ｍｇ·１￣（－１）。浸果和果面喷两种方法都可采用，关键是处理要均匀。ＣＰＰＵ与其它植物生长调节剂混用可以提高促进果实增大的效果，在生产上有更大的潜力。 After many years of experiments, we studied the effect of CPPU on the increase of Kiwifruit fruit. The results showed that the treatments with different concentrations of 5-40 mg · 1 ~ (-1) significantly increased the fruit of Actinidia chinensis and the effect was abnormal with an increase of 20% -190%. There appears to be no significant difference between the 10-30 mg · 1 -1 treatments, and the recommended optimum concentration is 10-20 mg · 1 -1. Baking fruit and fruit spray two methods can be used, the key is to deal with uniform. CPPU mixed with other plant growth regulators can increase the effect of promoting fruit growth, have greater potential in the production.
