摘　　要：研究了造林第一年三倍体毛白杨纸浆林间作棉花、苜蓿及黄芪三种间作物对林地性状、林木生长量的影响。结果表明,不同间作物对土壤理化性状、林木生长影响不同,间作棉花使表层土壤容重比对照低11.9%,有机质含量比对照高4.8%,速效氮比对照高13.0%,改良土壤的性状明显,同时,棉花影响范围的林木与其他处理之间在高生长没有显著性差异,但显著促进了胸径的生长,综合判断,造林第一年以间作棉花为好。The influence on soil properties and amount growth of trees were studied after trees planted first year.The results showed,cotton as a intercrop,surface soil bulk density was reduced 11.9% compared to control,the concentration of soil organic matter was higher 4.8% compared to control,the concentration of available nitrogen was higher 13.0% compared to control.The difference of the height of trees wasn＇t significance among different intercrops,but the difference of the diameter at breast height of trees was significance,On the whole,cotton was suitable intercrop.at first year.
