不同肥料对石笔木早期生长影响的研究

摘要

研究了5种肥料对石笔木地径、树高和冠幅年生长量的影响，并利用聚类方法分析得出最优的肥料种类。结果显示，国森林木有机无机复混肥(N-P-K：8-10-7)和女娲牌15%有机无机复混肥(N-P-K：5-5-5)对石笔木早期生长有较显著的促进作用。%The effects of five different fertilizers on ground diameter,height growth & crown annual growth of Tutcheria championi were studied.Clustering method was used to analyze the optimal fertilizers.Result shows that organic-inorganic mixed fertilizer of Guosen Brand(N-P-K:8-10-7)and Organic-inorganic mixed fertilizer of Nyuwa Brand (N-P-K:5-5-5)can improve the early growth of Tutcheria championi significantly.
