摘要
对马尾松-黑松混交林松材线虫病疫木构成及特点进行了研究,结果表明:黑松死亡率高于马尾松,两者比例为1:0.39;7月15日至8月15日是死亡高峰期,早期:中期:近期=1:0.22:0.10;枯死树径阶构成与林相自然径阶一致,平均为17.5cm;枯死木的质量明显低于健康木,健康木重量:胸径=7.857kg/cm,而枯死木重量:胸径=2.647kg/cm,后者只及前者的33.7%。
In this paper, constitute and characteristics of disease death wood caused by Bursaphelenchusxylophilus from forest of the Pinus massoniana mixed with P. thunbergii were studied. The resultsshowed as follows: The mortality of P. thunbergii was higher than that of P. massoniana, and theproportion was for 1:0.39. Death peak of pine trees was in the period between July 15 with August 15,and the proportion was: early: middle: recent=1:0.22:0.10. Diameter constitute of dead pine wood wasequal to natural forest, with an average of 17.5 cm. Quality of dead wood was significantly poorer thanthe healthy wood, and healthy wood’s weight:diameter at breast height=7.857 kg/cm. At the same time,the value of dead wood was 2.647 kg/cm. It was seeded that the latter was 33.7% of the former
