摘要
运用数理统计方法分析了泡桐不同粗度种根的苗木生长情况，结果表明：种根粗２．６～３．５ｃｍ时，苗木生长最好；种根粗度１．６～３．５ｃｍ时，出苗率和成苗率均很高；种根粗度对苗木高生长的影响，主要是影响苗木速生期的生长速度。
This paper deals with the relationship between the diameter of root一cutting and thegrovvth of nursery stock of Paulownia. The analysis shows:when the diameter of root一cut-ting is 2.6～3.5cm,the nursery stock grows best;When the diameter is 1.6～3.5 cm,thesurvival rate of the nursery stock is very high;The diameter mainly affects the growing speedof the nursery stock in the quick growing stage.
