DM对大叶相思苗木生长的作用研究

Effect of DM on Seedling Growth of Northern Black Wattle (Acacia auriculaeformis A. Cunn.)

研究了DM(DesertMagic,一种液体保水剂)与大叶相思苗木生长的关系.结果表明,使用DM能加速苗木的生长发育;苗高、地径、根长等生长指标明显高于对照;0～30cm土壤含水量显著提高.使用DM对培育大叶相思优质壮苗有良好的效果.

The relationships between DM (a kind of waterholding agent) and the seedling growth of northern black wattle were researched. The results showed that the seedlings treated with DM grew faster and stronger than those controlled seedlings, and their seedling height, aerial stem and root length all exceeded controlled seedlings. Moreover, it was observed that the water content of soil from 0 to 3 cm layer significantly increased in treatment than in control. Thus it was thought that to treat seedling with DM was effective for cultivating vigorous seedling of Acacia auriculaeformis A. Cunn..
