摘　　要：对应用杨树冰核细菌溃疡病综合防治技术的防治示范林样地进行调查。结果表明：经过防治后．幼林和成林村积与对照林相比有明显增长．幼林林水平均增长率７３．２１％，平均增长材积２７．３８ｍ３／ｈｍ２；红旗林场和三牧林场成林林木分别平均增长７６．０４％和８０．ｌ６％．材积分别平均增长１７８．９５ｍ３／ｈｍ２和２１３． ３０ ｍ３／ｈｍ２。至２０００年．此项成果在黑龙江省推广应用防治面积２．ｌ万ｈｎ２．按村积增长计算、获直接经济效益 ５ ３００万元。By investigating the demonstration-forest plot:through integrated control. the results show that the volume increase rates of young tarests and mature. forests are much higher than those that haven't been operated integrated control. young forests can make woods increase 73. 21 percent averagely and volume' increase 27. 68 m3 per hectare. while mature forests can make woods increase 76. 04 or 80. 16 percent and volume increase 178. 95 m3 or 213. 30 m3 per hectare. This research achievement 11as been spread in Heilongjiang Province. its spreading area reaches to 21 thousand hectare. calculated by volume increase. the direct economic benefit is 53 million Yuan.
