| 摘 要： | 柑橘生产上叶面肥的使用很普遍?为了评估喷施叶面肥对柑橘新梢期的主要害虫柑橘木虱Diaphorina citri和柑橘潜叶蛾Phyllocnistis citrella发生?为害的影响, 本文分别在养虫笼和网室条件下调查了以上2种害虫对喷不同叶面肥(尿素?复合氨基酸和葡萄糖)砂糖橘苗木的选择和为害, 以及柑橘炭疽病发生情况?试验结果表明:从木虱成虫选择性和产卵两个方面来看, 不同喷施处理的砂糖橘对木虱的吸引作用表现为尿素>复合氨基酸>葡萄糖>清水对照, 其中尿素和复合氨基酸处理吸引作用显著高于对照?喷施3种叶面肥后潜叶蛾为害程度均显著高于对照, 以葡萄糖处理的为害率和受害指数最高?另外, 尿素和复合氨基酸处理苗木的柑橘炭疽病病叶率和病情指数显著高于对照, 复合氨基酸处理病叶率显著高于葡萄糖?说明喷尿素?复合氨基酸叶面肥对柑橘木虱有较强的吸引作用, 同时加重柑橘炭疽病?另外, 与对照相比, 喷施3种叶面肥均能加重潜叶蛾的为害, 尤其是葡萄糖?

| Abstract: | Foliar fertilization is widely used in citrus production. In order to assess the influence of different foliar fertilizers applying in citrus on important citrus pests citrus psyllid Diaphorina citri and citrus leafminer Phyllocnistis citrella, the numbers of adults and eggs of this psyllid, the damage of citrus leafminer and citrus diseases on citrus young plants treated by three kinds of fertilizer, urea, compound amino acid and glucose were investigated in feeding cages and in net house. The results showed that the citrus psyllid most preferred urea, followed by compound amino acid, glucose and water (control). and the attraction of urea and compound amino acid treatment were significantly higher than control. There was a marked difference in damage indexes caused by citrus leafminer between foliar fertilization and the control. Among the three foliar fertilizer treatments, the most serious damage index and damage rate were citrus treated with glucose.The infected leaf rate and damaged index of citrus anthracnose in citrus treated with urea and compound amino acid were significantly higher than those of the control, and compound amino acid treatment was significantly higher than glucose in infected leaf rate. The results indicated that urea and compound amino acid had strong attraction to citrus psyllid and could cause citrus anthracnose heavier. In addition, compared with the control, the three foliar fertilizations can increase the damage of leaf miner, especially glucose. |
