摘　　要：以受杏树鬃球蚧为害的野杏为试材,采用双因素随机区组试验设计,研究了不同修剪时期(春季、夏季、秋季)和不同修剪强度(轻度、中度、重度)下杏树鬃球蚧虫口密度和野杏新梢生长的变化,以期探索出合理的修剪时期及强度,为通过修剪防控杏树鬃球蚧提供科学指导。结果表明:修剪时期和强度对杏树鬃球蚧虫口密度和野杏生长均有影响。从对杏树鬃球蚧的控制效果来看,春季修剪>夏季修剪>秋季修剪,重度修剪>中度修剪>轻度修剪;而从对野杏新梢生长的影响效果来看,秋季修剪>春季修剪>夏季修剪,重度修剪>中度修剪>轻度修剪,但秋季中度与重度修剪不利于野杏存活。从控制杏树鬃球蚧虫口密度和野杏生长2个方面分析,在春季对野杏进行中度或重度修剪为最适宜的修剪时期及强度。Taking A.vulgaris harmed by S.prunastri as the material with two-factor randomized block experimental design,the population density of S.prunastri and the new shoots growth of A.vulgaris in different pruning time(spring,summer,autumn)and intensity(light,medium,heavy)were investigated,in order to explore reasonable pruning time and intensity.The results showed that pruning time and intensity had effects on the population density of S.prunastri and the growth of A.vulgaris.In the control effect of S.prunastri,the results showed spring pruning>summer pruning>autumn pruning,heavy pruning>medium pruning>light pruning.In the effects of new shoots growth of A.vulgaris,the results showed autumn pruning>spring pruning>summer pruning,heavy pruning>medium pruning>light pruning,but medium and heavy pruning in autumn was not conducive to survival of A.vulgaris.In conclusion,the most suitable pruning time and intensity is the medium or heavy pruning of A.vulgaris in spring by analyzing from the two aspects of the control of S.prunastri and the growth of A.vulgaris.
