摘要
为了探究楠木人工造林成活率的施肥因素,通过对不同施肥处理下的楠木幼苗观测和分析,评估了不同施肥处理对楠木幼苗生长和成活率的影响.结果表明,尿素可促进楠木幼苗的叶片生长,过磷酸钙可提高楠木幼苗的成活率,成活率最高的施肥处理因素为20g过磷酸钙作为基肥,施肥因素对楠木幼苗成活率的影响大小依次为施肥方式、肥种、施肥用量.
Abstract
The purpose of this study is to explore the fertilization factors of the survival rate of Phoebe zhennan artificial afforesta-tion.Through the observation and analysis of Phoebe zhennan seedlings under different fertilization treatments,the effects of differ-ent fertilization treatments on the growth and survival rate of Phoebe zhennan seedlings are evaluated.The results show that the use of urea can promote the leaf growth of Phoebe zhennan seedlings,and the use of superphosphate can improve the survival rate of Phoebe zhennan seedlings.The fertilization treatment factor with the highest survival rate is 20 g of superphosphate as the base fertil-izer.The influence of fertilization factors on the survival rate of Phoebe zhennan seedlings is followed by fertilization method,fertil-izer species,and fertilization dosage.
