花期用1000mg·1~(-1)PP333和0.5%硼对巨峰葡萄进行叶面喷施,结果表明:1000mg·1~(-1)的 PP333能显著地延缓新梢、副梢生长,提高比叶干重(SLDW)和坐果率;0.5%硼无论单独或与1000mg·1~(-1)PP333混合使用,对新梢生长及坐果均无显著影响;0.5%硼和1000mg·1~(-1)PP333混合使用并不能改善因使用 PP333而引起的葡萄小果增加、着色差、成熟期延长的现象。
The results showed that 1000mg · 1 -1 PP333 can significantly delay the growth of shoots and shoots and increase the ratio Leaf dry weight (SLDW) and fruit set rate. 0.5% boron alone or mixed with 1000mg · 1 -1 PP333 had no significant effect on shoot growth and fruit setting; 0.5% boron and 1000mg · 1 ~ (- 1) PP333 mixed use does not improve due to the use of PP333 grape small fruit increase, poor color, prolong the phenomenon of maturity.
