摘要
分析了2019年利奇马台风对不同树形梨树落果率及枝叶损伤的影响。结果表明,纺锤形梨树落果最多,达90%以上;细长纺锤形梨树落果量70%以上;Y形梨树落果量最低,为30%左右。枝叶损伤与落果率的规律接近,由高到低依次为纺锤形>细长纺锤形>Y形。
Effects of Typhoon Lekima on fruit drop and damage of branches and leaves of pear trees with different tree shapes in 2019 were analyzed.The results showed that the fruit drop of spindle shape was more than 90%;that of slender spindle shape was more than 70%;and that of Y shape was the lowest,about 30%.The damage of branches and leaves was the same as that of fruit drop,and the order from high to low was spindle shape>slender spindle shape>Y shape.
