Discussion on the Control Effect of Closing Hillsides to Facilitate Afforestation on Dendrolimus punctatus Walker

This paper studies the control effects of Dendrolimus punctatus by closing hillsides to facilitate afforestation in Chongren and Yugan Counties in Jiangxi based on the principals of the sustainable pest management in forestry and ecology.The results shows that closing hillsides to facilitate afforestation is a safe,economical and effective measure for controlling Dendrolimus punctatus.By taking this measure,ecological environment and the minor climate of pine forests have been changed,the biodiversity in pine forests increased,the chemical and physical nature of soil amended,growth of stands improved and the ability of integrated resistance of pine forests to Dendrolimus punctatus enhanced greatly in Chongren and Yugan Counties.
