摘　　要：由于马尾松迹地改造不同于整地营造火力楠秃杉混交林、纯林,对幼林3年生的林木生长效果进行了对比分析。结果显示:火力楠、秃杉混交林的林木生长状况,分别均比纯林的林木生长状况良好,其树高于6.9%、34.8%,胸径粗于9.7%、30.8.%,冠宽于14.3%、16.7%。火力楠秃杉混交林的土壤肥力N、P、K,分别均大于纯林的土壤肥力N、P、K。Masson pine(Pinus massoniana)was transformed to create mixed forests and pure forests by different land preparation.The growth effect of 3A young forests was compared and analyzed.The results showed that the forest growth of mixed forests of MacClure michelia and Taiwania flousiana was better than that of pure forests,respectively.The tree height was greater than 6.9%and 34.8%;the DBH diameter was greater than 9.7%and 30.8%,and the crown width was greater than 14.3%and 16.7%.The soil fertility N,P and K in the mixed forests of MacClure michelia and Taiwania flousiana were higher than those in the pure forests,respectively.
