通过调查、观测,掌握了红松根朽病在勃利县林区发病规律以及环境因素对该病害的影响。结果表明,红松根朽病的发病规律为:郁闭度大的林分病害较重,阴坡重于阳坡,山中下腹重于山上腹;使用树干基部涂药和根部注药相结合的方法防治效果最好,防治效果达95%以上。
通過調查、觀測,掌握瞭紅鬆根朽病在勃利縣林區髮病規律以及環境因素對該病害的影響。結果錶明,紅鬆根朽病的髮病規律為:鬱閉度大的林分病害較重,陰坡重于暘坡,山中下腹重于山上腹;使用樹榦基部塗藥和根部註藥相結閤的方法防治效果最好,防治效果達95%以上。
통과조사、관측,장악료홍송근후병재발리현림구발병규률이급배경인소대해병해적영향。결과표명,홍송근후병적발병규률위:욱폐도대적림분병해교중,음파중우양파,산중하복중우산상복;사용수간기부도약화근부주약상결합적방법방치효과최호,방치효과체95%이상。
Through survey observation,occurrence pattern of roo-rot of Pinus koraiensis in Boli county influence of environmental factors on this disease were mastered.Occurrence pattern of root-rot of Pinus koraiensis is that: plant disease of stand with large canopy density is severe;plant disease on shady slope are severe than that on sunny slope;plant disease on middle lower part of the mountain is severe than that on upper part of the mountain;combining the method of drug-coated on the base of the trunk and root injection can get the optimal control effect,which being 95% or more.
