用天然养殖助长剂（ＡＡＢ）喷洒处理日本落叶松播种苗，经过１年的生长，与对照的苗木相比，苗木高生长平均增加０６ｃｍ，地径生长平均增加０１４ｃｍ，主根生长平均增加０７５ｃｍ，侧根数量平均增加００５根。经对数据的方差分析发现，ＡＡＢ对苗木的高生长和地径的生长有显著的促进作用。
Compared with the control seedlings, the growth of seedlings increased by 0.6cm on average and the average diameter growth increased by 014cm after one year of growth by spraying natural larch seedlings with AAB. Increase 0 75cm, an average increase of lateral root 0 05 roots. Analysis of variance of the data showed that AAB could significantly promote seedling height growth and diameter growth.
