Applied Research of ABT Producing Roots Powder Effect on the Larix Principis-rupprechtii Raising Seedling

报道了ABT生根粉 6# 、 8# 在华北落叶松播种育苗上的应用研究结果。 1999年 5月用ABT生根粉 6# 、 8#对华北落叶松种子浸种处理 ,于 7月 5日、 7月 2 0日 ,在苗木生长旺期喷叶两次 ,并以清水做对照。同年苗木生长结束后 ,对生长情况进行调查。结果表明 :用ABT生根粉 6# 2 0 / 溶液浸种 2h ,于苗木生长旺期 ,再以 10 / 溶液喷叶两次 。

The results of applied research that ABT producing roots powder effect on the Larix principis-rupprechtii raising seedling was reported in this paper. ABT producing roots powder number 6 and number 8 were used for Larix principis-rupprechtii raising seedling, qin seed 2 hours in May, 1999, and spraying seedling with 10 / and 15 / twice in July 5, 1999 and July 20,1999 respectively, and was contrasted with pure water. The effects investigated after the seedling stop growing. The results showed that effect of Larix principis-rupprechtii raising seedling is the best with ABT producing roots powder number 6 qin seed 2 hours and spraying twice at 10/ in the seedling growing fast period.
