| Abstract: | Based on the data from investigation on sample plots of young Pinus massoniana forest,the effect of damage caused by Dioryctria rubella on the growth of young P.massoniana forest was estimated,meanwhile the shoot cutting technique was briefly introduced.The results showed that,the damage of D.rubella had a significant effect on the growth of young P.massoniana plantation.After suffering the damage of D.rubella,the current growth of leading shoot was reduced by 27.23%,and the tree height growth decreased by 13%,while the ground diameter growth increased by 7.23%.The damage of D.rubella not only influenced the shoot growth in the first year,but also influenced the shoot growth in the next year.After suffering the damage,the shoot growth was deeply influenced with tree height of 141~180cm.Hence,the aim of control should focus on the pine with the height from 141 cm to 180 cm,namely,the pine in the age between 3 to 4 years old.Comprehensive analysis of the occurrence characteristics of D.rubella in Hunan showed that,the shoot cutting to control D.rubella should be carried out in the early-middle May in Hunan province. |
