摘　　要：研究不同次数根外施硼对新红星苹果树光合速率年变化的影响 ,结果表明 :根外施硼可以增加新红星苹果树叶片叶绿素含量 ,提高蒸腾速率 ,促进光合速率。一年中 ,根外施硼效果以三次为宜 。The experiment was carried out to study the effect of leaf spraying Boron on annual variation of photosynthesis in Starkrimson Apple Trees. The results showed that: the content of chlorophyll, transpiration rate and photosynthetic rate increased. During the year, the effect of spraying B with three times and in the late growing season is better.
