摘要
在长白落叶松苗木生长旺盛期叶面喷洒植物核心植物生长调节剂的试验结果表明 ,不同浓度的植物核心均可促进苗木生长 ,且以 1∶1 0 0浓度的效果好 ,有明显的增产趋势。新播苗 (S1 - 0 )增加苗高 1 4 %、地径 1 3%、鲜重 2 5 %,换床苗 (S1 - 1 )增加苗高 2 0 %、地径 2 0 %、鲜重 4 6 %,并能提高苗木品质 ,经济效益也十分明显。
The plant growth regulator-plant nucleus of spraying was used on the seeding leaves of Larix olgensis at the period of growth quickly. The test result showed that the seedling plant nucleus growth was improved by using in defferent density,and the density 1∶100 was best effectiveness in increased production.To the seedling (S 1-0),the seedling high,the ground diameter and the fresh weight were inceased by 14%,13% and 25%.To the transplanting seedling(S 1-1),the seedling high,the ground diameter and the fresh weight were in creased by 20% and 46%.The quality of seedlings was increased and economic effection was also remarkable.
