果树进入盛果期，普遍存在落花落果、座果率低等问题，而影响果树产量。为探讨产果量与花期授粉，花粉硼含量的内部机制，试验采用梨、柿等花粉在发芽床（琼脂1％、蔗糖15％）上加入硼酸或硼砂进行花粉发芽观测，在果园中则分别于开花前、花后、果实生长期喷硼，浓度为300－500 Fruit trees into full fruit period, the prevalence of falling flowers and fruit, fruit rate is low and other issues, and affect the yield of fruit trees. In order to explore the internal mechanism of fruit yield and pollen boron content in pollination, pollen germination was measured by adding boric acid or borax on the germination bed (agar 1%, sucrose 15%) using pollen of pear and persimmon, Before flowering, after flowering, the fruit is sprayed with boron at a concentration of 300-500
