摘要
对 1年生新播兴安落叶松容器苗不同生长期内 N、 P、 K浓度的分析结果表明 :兴安落叶松幼苗在生长初期 ,针叶及整个植株中的 N、 P、 K含量均为最低 ;进入速生期时 ,植株中全氮、全磷达到最大值 ,而全钾则在速生后期才达到最大值。兴安落叶松植株 N、
In order to study the nutriment characteristic in the seedling stage,the dynamic characteristic of the nutriment cycling and the interaction of different nutriment about Larix gmelinii,the author analyzed the N(nitrogen),P(phosphor),K(potassiunm)content of one-year-old container sample seedling of Larix gmelinii in different growing period in Daxing'anling container nursery during 1994 and 1995.The results declare that the N,P,K content of the needles and the whole seedlings is the lowest in the inital growing period.When the seedlings entered the fast-growing stage,the N, P content reached the highest peak.However the K content would be the highest peak in the later fast-growing period.There is positive correlativity between the N,P metabolism of Larix gmelinii seedling.
