【摘要】 通过赤霉素、硼酸对仁用杏保花保果试验及 PP333对仁用杏促进生长、结实技术的研究 ,初步认为 ,在不同浓度处理中 ,赤霉素提高坐果率的最佳浓度 ,龙王帽为0 .0 0 1 % ,一窝蜂为 0 .0 0 2 %。硼酸提高坐果率的最佳浓度 ,龙王帽为 0 .3%、一窝蜂为0 .5 %。PP333以 0 .5 %～ 0 .8%的浓度处理较好更多还原

【Abstract】 Initial study shows that in different concentration treats,the best gibberellin concentration of raising fruit set percentage is 0.001% for Long wangmao and 0.002% for Yi wofeng,the best boric acid comcentration is 0.3% for Long wangmao and 0.5% for Yi wofeng,and the best Concentration of PP 333 is 0.5～0.8% which can obviously raises fruit set percentfage,and accelerates growth after analysing the effeces of gibberellin and boric acid’s flower and fruit drop control on the kernel used Apircot.更多还原
