摘要
以马蹄荷播种苗为试材,在黄心土和肥沃表土2种基质上育苗,施用浓度为0.5%的高氮型、高氮高钾型、高氮高磷型和普通型4种类型混合肥,研究不同基质条件下施肥对1年生苗木高度和地径生长的影响。结果表明:不同基质条件下的N、P、K施肥处理,对马蹄荷播种苗的苗高和地径生长均有极显著的促进作用。在比较贫瘠的黄心土基质上培育马蹄荷苗木以N、P、K比较均衡的施肥配方效果最佳,且应适当增加施肥浓度或施肥次数以提高苗木生长量;而在肥沃表土基质上则以N和K比例较高的施肥配方效果最佳。
One-year-old Exbucklandia populnea seedlings were planted in two types of loess and fertile soil matrixes.The effect of loading 0.5% nitrogen（N）,high nitrogen（N）and potassium（K）,high nitrogen（N）and phosphorous（P）contained fertilizers,and the common fertilizer were used on Exbucklandia populnea seedling growth,seedlings′height and ground diameter were studied.The results showed that seedling growth was greatly improved with both matrixes.Exbucklandia populneaseedling grew better when loaded balanced N,P,K on the loess matrix.Exbucklandiap opulneaseedling growth increased when the fertilizer loading quantity and frequency were increased.However,high N and K fertilizer improved Exbucklandia populnea growth mostly on fertile matrix.
