大果榉苗木施肥效果研究

对大果榉1年生容器苗进行施肥试验的结果表明,各施肥处理间生长节律相似,但不同施肥处理对生长的影响不一,除磷钾处理外都高于对照,且影响主要表现在高生长上。综合分析,效果最好的是N：P：K为2：4：1的配方肥,通过SPSS软件对净增长量进行方差分析效果明显,得出的结论与土壤含量分析结果相符。同时也指出在本试验研究中磷钾处理会抑制高生长,增加木质化程度有待进一步探索,因此要根据土壤肥力情况进行合理施肥。

Research on Effect of Fertilization for Zelkova sinica Seedling

The fertilization practice test of 1year old container seedings of Zelkova sinica was studide..The result showed that all the fertilization treatments have a similar effect in rhythm of plant growth.Except the phosphorus and potassium group,the height of all the fertilization treatment group were higher than the control group.After comprehensive analysis with SPSS,we find the best compound fertilizer ratio of N:P:K was 2:4:1,which were in accordance with the soil,while the result also showed that the phosph...
