1993年7月中旬．我们对5年生苹果梨密植幼树上部旺技进行了控旺促花处理，结果在抑制旺枝上新梢生长方面，B91500mg／kg、拧梢、乙烯利1000mg／kg和乙烯利＋双刀环割与对照差异极显著；环剥、乙烯利1000mg／kg、双刀环割、乙烯利＋双刀环割有明显的促花作用，与对照差异极显著；B9、双刀环割、乙烯利、乙烯利＋双刀环割还明显地促进了处理单株的花芽形成，与对照差异显著，并使枝果比更趋合理.
Mid-July 1993 We were on the apple-pear-tree seedlings in the upper 5-year-old Wang Wang technology to control the prosperous and flower treatment, the results in inhibiting the growth of new shoots on the branches, B91500mg / kg, screw tip, ethephon 1000mg / kg and ethephon + The results showed that there was significant difference between the cut and the control. The results showed that there was significant difference between the control group and the control group, such as G9, Ethephon 1000mg / kg, , Ethephon + double ring cut also significantly contributed to the treatment of single flower bud formation, significant difference with the control, and make the branch ratio more reasonable.
