<正>在研究林业站职能转变大背景的基础上，从林业站的工作目标、林业生产过程两个方面对林业站职能进行分析。结果表明，林业站的部分职能已经无法与其自身的能力和社会的需求相适应。提出了基层林业站职能转变的方向，指出林业站进一步改革中应注意的问题。

Through tissue isolation and plate dilution, 891 bacteria isolations were obtained from healthy and diseased leaves of pines. By the dural culture method on PDA plates with pathogens, 16 bacteria isolates had strong antagonism against Sphaeropsis sapinea. Under artificial inoculation 10 representative strains were used on the seedling of pines in green house for identifying their biocontrol effects on S. sapinea. Three (Strain number N29, M (2) 21 and S (1) 102) of 10 isolates had both good roles on PDA plates and seedlings of pine trees. The diameters of their inhabit circle were respectively 28.5, 31, 37.5mm and protective effection to the seedlings of pine was over 60%. The result of pathogenicity test demonstrated that they had no harmful influence to the seedling of pine.
