摘要
为研究配方施肥对杉木生长的影响,设置6个施肥处理,研究杉木形态特征和物质积累的变化特征。结果表明,增施氮、磷、钾肥均能提高杉木幼苗株高、茎粗和分枝数,且能够显著增加根系和茎部的干鲜重。其中氮肥优化处理的株高、茎粗和分枝数最高,干物质积累量最多,是较好的施肥模式,可作为杉木幼苗栽培的推广施肥方案。
In this paper,in order to study the effects of formulated fertilizing on the growth of Cunninghamia lanceolata,6 fertilizing treatments were designed to study the variation characters of the species in morphology and material accumulation.The results showed that increased fertilizing of nitrogen,phosphorus and potassium could promote the height,basal diameter and branching number of the seedlings and also significantly increase the fresh weight and dry weight of the root system and stem.Of the formulated fertilizing treatments,the optimal nitrogen fertilizing,which could make the seedlings achieve the biggest height,basal diameter,branching number and accumulation of dry material,is a good fertilizing mode and could be promoted as a fertilizing plan for cultivating Cunninghamia lanceolata seedlings.
