The experiments for determung optimum seedlings density were made in the nursery of Experimental Forest Farm of Liaoning Province. Qingyuan County, in 1997. The results of 4 repeating experiments for six densities were analyzed using variance analysis by single factor. Seedling density has great effects on growth of diameter(at foot) and height. The proper seedlings density forAralia elata was determined to be 55–65 stems/m2, or 330000 390000 hm2. Thus density can insure individual seedling’s quality and the maximum productivity of seedlings.展开更多
