池杉幼苗移栽解决了播种苗出苗不齐、断苗、间苗浪费,以及1年生苗移栽出圃周期长、留床苗造林成活率低、缓苗期长的问题,于播种当年4月下旬至5月中旬进行移栽,成活率达到98％,当年地径生长比播种苗显著增加。用此法培育大苗,可以2年出圃,苗木质量与3龄移栽苗相同而优于留床苗,造林成活率分别比3龄移栽苗、2龄和3龄留床苗高1.8％、8.3％和11.6％。
Ipadia seedlings transplanted to solve the sowing seedlings missing, broken seedlings, thinning waste, and a one-year-old seedlings transplanted nursery cycle long, leaving bed seedling afforestation survival rate is low, the slow seedling period problems, sowing in late April of that year To mid-May for transplanting, the survival rate reached 98%, year diameter growth significantly increased compared with sown. Seedlings can be nurtured by this method and can be nursery for 2 years. The quality of nursery stock is the same as that of 3-year-old transplanting seedlings, and the survival rate of afforestation is 1.8% higher than that of 3-transplanting seedling, 2-year- 8.3% and 11.6%.
