摘要
于2009—2010年对福建省27个县(市、区)引种的596.2 hm2的湿加松试验林进行病虫害监测调查,发现湿加松林分有16种林业有害生物发生危害。其中,松赤枯病、松针褐斑病、松枯梢病、桃蛀螟、微红梢斑螟、马尾松毛虫等6种病虫害分布面积较大、发生较普遍,其分布面积均占试验林总面积的10%以上,尤其是松赤枯病分布面积占试验林总面积的48.53%;幼林以微红梢斑螟和桃蛀螟为主,造成嫩梢被蛀枯死、多头或针叶枯死;随着林龄增大,病虫害种类和发生面积呈上升趋势,松枯梢病、松针褐斑病等病害随之侵入,且越来越严重。统计分析表明,南亚热带区病虫害种类和分布面积占造林面积的比例虽然与中亚热带区差异不大,但南亚热带区较适宜湿加松生长,长势较好,基本上处于病虫不成灾的状态。
After the investigation on pest in 596.2 hm2 hybrid pine ( Pinus elliottii ×P.caribaea) introduction trial plantation of 27 counties in Fujian Province during 2009~2010,16 pests were found.But the distribution area of 6 pests of Pestalotiopsis funerea Desm.,Lecanosticta acicola Sydow,Sphaeropsis sapinea(Fr.:Fr.)Dyko&(Sutton,Dichocrocis punctiferalis Guenee,Dioryctria rubel-la Hampsom,Dendrolimus punctatus Walker were greater than other pests distribution area ,each of their distribution area was above 10%of the total trial plantation area.Especially , the distribution area of Pestalotiopsis funerea Desm.owned 48.53%.The species number and distribution area of pests increase with stands age ,damaged mainly by Dichocrocis punctiferalis Guenee,Dioryctria rubella Hampsom to cause infected young shootes withering and arbuscular bull in young plantation .The damage on hybrid pine infected by Sphaeropsis sapinea( Fr.:Fr.) Dyko & Sutton and Lecanosticta acicola Sydow were getting more and more serious with age of stands.Through the statistical analysis ,there was no obvious difference between south subtropics region and middle sub -tropics region on the species number of pests and proportion of their distribution area in their region plantation area ,but these pests couldn ’ t take serious damage in south subtropics reg-ion.The result showed it was more suitable for growth of hybrid pine in south subtropics re -gion than middle sub-tropics region.
