巨尾桉造林营养液浸苗试验

利用天达2116壮苗灵不同浓度营养液,对巨尾桉无性系造林进行了浸苗试验。结果表明:600倍浓度的天达2116壮苗灵,对造林成活率影响不明显,但能缩短种植后的缓苗期,显著地促进树高生长,使高生长量较对照增加19.9%。

Study on Soaking Seedlings to Afforestation with Nutrient Solution

Using soaking seedlings method with different concentrations of Tianda 2116,afforestation experi-ment of E. grandis×E. urophylla clones was carried out. The result showed that 600 times liquid of Tianda 2116 for strong seedling had no obvious effect on afforestation survival rate,but it could shorten the reviv-al time of seedlings and promote significantly height growth.Compared with ck,its height growth increased 19.9%.
