摘要
经５年试验表明，厚朴苗木地径８ｍｍ以上时，其苗高对幼林生长无显著影响，苗木过高将降低造林成活率；厚朴幼林施化学氮磷基肥，只对补期生长有促进作用，但与对照相比差异不显著，３年后差异完全消失。
5 years experiments resulted that when rhizome diameter of Magnolia biloba seedling was over 8mm,seedling height had no evident effect on young growth,but when seedling was too high(over 90cm),survival rate of afforestation would decrease.Application of N and P base manure in young growth,only had acceleration of initial growth,but no significant difference compared with control.
