摘要
对3个中晚熟品种进行不同浓度PP333处理,每品种设每株叶面喷施PP3338000mg/L、10000mg/L、12000mg/L和喷清水对照4个处理,单株为一小区,重复3次,随机区组设计,处理1分2次喷,第一次在5月9日,第二次在6月9日,其余在5月9日喷1次。研究表明,PP333能极显著地抑制枝梢生长。从控制枝梢生长、产量提高、果实形状及圆整度、花芽形成等综合性状分析,4年生大团蜜露以每株喷PP33312000mg/L、5年生湖景蜜露和6年生西浦1号以每株PP3338000mg/L喷2次的处理效果最好。
Effects of PP333 on growth of shoots of ＇Datuanmilu＇, ＇Hujingmilu＇ and ＇Xipu No.1＇ trees were studied. The study showed that the growth of shoot of medium-late melting peaches was significantly restrained by different concentrations of PP333. From results of shoots growth, yield, and the shape of the fruits, the best concentrations are the 12000 mg/L of PP333 for foru-year-old ＇Datuanmilu＇ and 8000 mg/L for five-year-old ＇Hujingmilu＇ and six-year-old ＇Xipu No.1＇.
