摘要
通过对福建柏进行在不同施肥措施下育苗、不同家系种子育苗试验，以及不同苗木留床密度对苗木质量的影响的研究，结果表明：（1）福建柏播种前施足基肥钙镁磷（50kg／667m^2）效果最好，苗期遮阴为关键环节。1a生福建柏苗木平均密度为123株/m^2时，当年平均地径0．43cm，平均苗高达33．4cm，Ⅰ级苗率为77．46％，Ⅱ级苗率为18．26％，苗木合格率可达95．72％，苗木保留密度以115～120株／m^2为宜。（2）在37个家系种子育苗试验中，3号、7号、12号、16号、25号、34号、37号表现较好，苗木合格率达97％以上。（3）对福建柏播种苗分别设计施加钙镁磷、农家肥、火烧土和不施肥等4个处理小区试验，与对照相比，施用钙镁磷肥效果最好，其次是农家肥，火烧土苗木长势较差。
Tests of fertilization measures on Fokienia hodginsii seedlings,pedigree seedlings and seedlings bed density on seedling quality show that： （1） Plus base manurecalcium and magnesium phosphate （50kg/667m^2） can achieve the best results before planting, and shade is the key point. Annual Fokienia hodginsii seedlings＇ average density of 123 plants/m^2, the average diameter of 0.43cm, the average height of 33.4cm, the the level Ⅰ seedling rate of 77.46%, the class Ⅱ seedlings of 18.26%, the qualified rate of seedlings up to 95.72%, seedlings appropriate reserved density of 115-120 plants/m^2. （2） In 37 pedigrees, pedigree of 3,7, 12, 16, 25, 34,37 performance better, and the qualified rate of seedlings up to 97% and above. （3） Four fertilization measures of calcium and magnesium phosphate, manure, burned soil and no fertilizer on Fokienia hodginsii seed- lings, compared with the contrast, the effect of the application of calcium magnesium phosphate best, followed by manure, the burned soil worst.
