摘要
通过对1年生长白落叶松播种容器苗不同生长期内N、P、K浓度进行分析,得到在幼苗生长初期,整株的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。长白落叶松植株N、P代谢之间呈显著的正相关关系。
Concentration of N,P,K of annual container-seedlings of Larix logensis during different growth stages were analyzed. It showed that N,P,K content of whole plant were the lowest during the seedling stage.When it reached fast-growing period,total nitrogen(TN),tatal phosphorus (TP)of plant got the maximam value,total potassium (TK)got the maximam value after fast-growing period.There was significant correlation between metabolize of N and P of Larix olgensis.
