摘　　要：以泰栗1号板栗品种为试材,研究了不同喷药次数下红蜘蛛对板栗生长及结实的影响。结果表明,随喷药次数的增加,板栗红蜘蛛危害程度呈显著下降趋势,其中处理Ⅲ(喷药3次)的防治效果最好,其叶片质量、果前梢与混合芽质量、坚果品质与产量均好于其它处理。以5%噻螨酮乳油2 000倍加10%浏阳霉素乳油1 000倍液喷药2～3次为宜。The effects of red spider on chestnut growth and bearing were studied under different spraying times with the variety Taili 1 as material. The results showed that the injury extent caused by chestnut red spider declined markedly with the increase of spraying times. The control effect of the third treatment was the best showing the best quality of leaves, mixed buds and tailed twig and also the nut yield and quality. It was optimal to spry 2∽3 times with 2 000 times of 5% hexythiazox EC and 1 000 times of 10% Liuyang mycin EC.
