华山松主要病虫害综合治理研究

Integrated management of the important pests in armand pine(Pinus armandi Franch)

为了解决林业生产中华山松主要病虫害 (华山松疱锈病、华山松腐烂病、华山松木蠹象、华山松球蚜 )综合治理的技术难题 ,首次提出了华山松主要病虫害综合治理技术。该技术以华山松为保护对象 ,以 4种主要病虫害为治理对象 ,做好预测预报 ,采取以预防为主 ,营林技术措施为基础 ,生物防治为主导 ,在阈值原理调控下 ,科学地采取生物、物理、化学防治等治理措施 ,逐渐增加华山松森林生态系统的生物多样性 ,使其结构逐渐趋向合理 ,最终达到华山松主要病虫害的可持续控制和华山松森林生态系统的持续平衡发展 ,为华山松生产谋取最大的效益。

In order to solve the technical problems in integrated management of the important pests of armand pine i.e.Cronartium ribicola,Valsa sp.,Pissodes yunnanensis,Pineus armandicola, the integrated management technooques of the main diseases and pests were raised for the first time.The techniques take the armand pines as the main protective target and the four pests of armand pines as the main controll targets.They include prediction and forecast, prevention first,taking the silviculture measures as basis,taking the biological control measures as the leading factor,under the regulation of threshold principle,taking the measures such as biological control,physical control and chemical control scientifically.As a result,the biodiversity of the armand pine forests ecosystem gradually increases,the structure of this system tends to be reasonable and finally the goal of the sustainable management of the main pests,and the sustainable and balanced development of the ecosystem can be attained.
