ABT生根粉对云杉苗移植生长效应的试验

A Experiment on Growth Effect of Picea Transplant SeedlingsTreated with ABT Root-forming Powder

用ＡＢＴ３号生根粉对２年生云杉原床苗浸泡后进行移床试验，经测试，移床当年和第２年苗高、当年高生长、地径、主根长、侧根数等指标，明显优于常规移床苗，且苗色正常、顶芽饱满，使苗木出圃由５ａ提前为４ａ，各项质量指标均达到或超过部颁标准。

The study of transplant experiment on 2-year Picea nursery seedlings immersed with No.3 ABT rootforming powder indicated that indices such as seedling height transplanted for 1 or 2 years、height growth in those years、diameter at root、length of main root and numbers of lateral root are superior to conventional transplant seedlings obviously. Moreover, the treated transplant seedlings are characterized by normal seedlings color、plump phyllogen and the age out of nursery is 4, one year ahead of time. All those quality indices came up to or beyond quality standards promulgated by Forestry Department of China.
