以千年桐幼苗为研究对象,通过田间试验、室内分析及统计软件等方法,对不同处理方式下营养元素特征进行研究,结果表明,浸种后千年桐各构件P、Mg、Mn、Cu、Zn等养分含量呈增加趋势,而N、K、Ca、Fe、Al、S等养分含量呈减少趋势,其中P、K、Mg、Cu、Zn的变化率均超过了10%;各主要元素随季节动态变化幅度大,浸种与未浸种各构件N、P含量基本表现出先降后升的趋势,而K含量则基本表现出先升后降的趋势。
以韆年桐幼苗為研究對象,通過田間試驗、室內分析及統計軟件等方法,對不同處理方式下營養元素特徵進行研究,結果錶明,浸種後韆年桐各構件P、Mg、Mn、Cu、Zn等養分含量呈增加趨勢,而N、K、Ca、Fe、Al、S等養分含量呈減少趨勢,其中P、K、Mg、Cu、Zn的變化率均超過瞭10%;各主要元素隨季節動態變化幅度大,浸種與未浸種各構件N、P含量基本錶現齣先降後升的趨勢,而K含量則基本錶現齣先升後降的趨勢。

This paper took Vernicia montana seedlings as research objects,and compared with nutrient ele-ments in different disposing methods through field experiments and analyses in door.The results showed that:After soaking of V.montana seeds,P,Mg,Mn,Cu,Zn content of all the tissues were increased,and the N,K,Ca, Fe,Al,S nutrient content showed a trend of decrease.Among of them,the rate of change of P,K,Mg,Cu,Zn was more than 10%.The major nutrient elements such as C,N,P,and K showed wide change range.Seed soa-king or not,N and P content decreased first and then increased,while K content showed a different trend,which was increased first and then decreased.
