Study on Selection of Suitable Intercrops of Triploid Populus tomentosa Pulp Forests
摘要
Abstract
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.关键词
