摘要
在青海云杉换床过程中,采用ABT-3号、ABT-7号、萘乙酸(NAA)、吲哚丁酸(IBA)4种激素对苗木进行了处理,分析了各种激素对青海云杉换床苗木成活率的影响。研究表明:青海云杉原床苗换床时,激素处理对提高换床成活率具有极显著作用,其中以ABT-7号生根粉处理效果最优,ABT-3号生根粉次之,NAA与IBA处理之间的效果相近,但与对照相比仍很显著。
In the course of transplanting Picea crassifolia,the transplanting seedlings are treated respectively by using ABT-3,ABT-7,naphthylacetate (NAA) and indole butyric acid (IBA),in order to analyze the influences of various hormones on the survival rate of Picea crassifolia Transplanting Seedling.The results show that the hormone treatments play significant roles in improving the survival rate of transplanting seedlings,and the effects of ABT-7 are the best,the following is ABT-3,and the effects of NAA and IBA treatments are similar.
