不同种类肥料对银缕梅苗木生长影响的研究

Study on Effects of Fertilizer Types on the Growth of Parrotia subaequalis Seedlings

为了研究不同种类肥料(泥炭土、氮肥、有机肥、氧化钾、磷肥和硫酸钾)对珍贵树种银缕梅1年生实生苗生长的影响,采用单因素试验设计方法,测定了施用不同肥料后苗木的株高、地径、生物量等指标。结果表明,泥炭土和有机肥施肥后在苗高、地径、叶生物量、根生物量和茎生物量方面均具有较好的促进作用。由此可见,泥炭土、有机肥可以应用于银缕梅实生苗培育。

In order to study effects of fertilizer types （ peat soil, nitrogen fertilizer, Shitai organic fertilizer, potassium oxide, phosphate and potassium sulfate） on 1-year-old seedlings of the rare tree species Parrotia subaequalis , a single-factor test design was adopted to determine indexes including the seedling height, basal diameter and biomass after application of different fertilizers. The results showed that peat soil and Shitai organic fertilizer had good facilitation on the seedling height, basal diameter and leaf, root and stem biomasses and could be applied to cultivating Parrotia subaequalis seedlings.
