| 摘 要： | 通过对吐伦球坚蚧Rhodococcus turanicusArch.种群密度与杏树产量的调查和田间药效试验研究得出:40%毒死蜱·机油乳剂对其防治效果较好,7d后的防治效果可达83.99%;初步探明了吐伦球坚蚧的为害损失率,建立了杏树损失率与吐伦球坚蚧种群密度的回归模型为y=24.671Ln(x)-16.56(y为杏产量损失率,x为种群密度,单位为头/30cm),相关系数(R2)为0.82,并制定了不同价格下吐伦球坚蚧的防治指标。

| Abstract: | By the way of investigation to the field efficacy trial and the population density of Rhodococcus turanicus Arch.,The result showed the control effect of 40% Chlorpyrifos+engine oil is significant,the relative control effect of 40% Chlorpyrifos+engine oil was 83.85%,The regression model between the loss rate of apricot and R.turanicus population was established as follow:y = 24.671Ln(x)-16.56(y:the loss rate of the yield,x:the population density of R.turanicus,the unit was head/30 cm),the correlation coeffi... |
