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。
研究瞭造林第一年三倍體毛白楊紙漿林間作棉花、苜蓿及黃芪三種間作物對林地性狀、林木生長量的影響。結果錶明,不同間作物對土壤理化性狀、林木生長影響不同,間作棉花使錶層土壤容重比對照低11.9%,有機質含量比對照高4.8%,速效氮比對照高13.0%,改良土壤的性狀明顯,同時,棉花影響範圍的林木與其他處理之間在高生長沒有顯著性差異,但顯著促進瞭胸徑的生長,綜閤判斷,造林第一年以間作棉花為好。

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.
