Study ofPlanting Technology of Mixed Forest withMasson Pine and Acacia Confusa

Masson pine andAcaciaconfusawere planted to be pure forest and mixed forest in cutting blank of cunninghamia lanceolata,after more than 10years of fertilization,tendingand operating management,thetrees grow well.This article compares the forest standsofthe pure forest and the mixed forest.The results indicate thatthe average height,dbh and volume of the mixed forest is respectively higher than the pure forest ofMasson pine and Acaciaconfusaaccounting for 2.43% and 12.46%,6.3% and 12.71%,11.92% and 36.84%separately.Therefore,the mixed forest hasreasonable stand structure with improved soil nutrient content and fertility.
