摘 要:指出了运用青钱柳育苗繁殖栽培技术,采种育苗繁殖,培育青钱柳一年生苗木在杉木采伐迹地造林,杉木萌芽后,形成青钱柳杉木混交林。经过8a的经营管理,青钱柳杉木混交林林分生长量,比青钱柳纯林林分生长量增加很多。经调查分析显示:混交林造林后的林木生长保留株树、树高、胸径、树冠、单株材积、郁闭度,分别大于青钱柳纯林造林后的林木生长保留株树多0.40%、树高大8.12%、胸径粗11.97%、树冠10.26%、郁闭度12.5%,单株材积大25%、蓄积量多23%。这表明了青钱柳杉木混交林模式值得推广。The breeding and cultivation technology of Cyclocaryapaliurus is to plant and breedseedlings.The annual seedlings of Cyclocaryapaliurus will be cultivated in the afforestation of Chinese fir cuttings.After the germination of Chinese fir,the mixed forest of Chinese fir and Chinese fir will be formed.After the management of 8 a,the growth rate of the mixed forest was better than that of pure forest.According to the investigation and analysis,after afforestation of mixed forest,the tree growth,tree height,chest diameter,canopy,individual timber volume and canopy density were 0.40% more,8.12% higher,11.97% higher,10.26% higher,12.5% higher,25% higher and 23%higher respectively.This indicates that the mixed forest model of Chinese fir is worthy of promotion.
