１９９１年９月和１９９２年５月两次对平坝、威宁华山松种子因病虫进行了详细调查．结果表明：（１）华山松种子园病虫的种类与为害情况，随海拔的不同而异，总的趋势是种类少，优势种明显，为害不严重；（２）病害（松赤落叶病，华山松煤污病）的为害与寄主的种源、无性系号无显著关系，病害在种子园内呈聚集分布，有明显的发病中心，不同小区之间的感病指数有明显差异；（３）天敌资源比较丰富；（４）病虫的发生与气候因子关系密切，大暴雨对华山松蚜虫和煤污病有着显著的控制作用．本文根据不同种子园的病虫发生情况提出了防治措施． September 1991 and May 1992 twice on Pingba, Weining Huashan pine seeds for a detailed investigation. The results showed that: (1) The species and damage of pests in Pinus armandii seed orchard were different with altitude, the general trend was less species, dominant species was obvious, the damage was not serious; (2) Diseases Huashan Songyu disease) and the host’s provenance, clones no significant relationship, the disease in the seed garden were gathered and distributed, there is a clear center of disease, the difference between the susceptibility index was significantly different; (3 (4) The incidence of pests was closely related to climatic factors, and the heavy rain had a significant control effect on the occurrence of aphids and coal fouling of Pinus armandii. Based on the occurrence of pests and diseases in different seed orchards, this paper puts forward control measures.
