Abstract:

In the Quaternary red clay soil, formula fertilization growth effect is: different formulations treated shows significant difference in diameter growth, height growth were very significantly different in continually for three years on Zenia nsignis Chun young trees. Multiple comparison shows that the diameter and tree height growth effects maximum at diameter growth increase37.04% and height growth increased 33.85% on phosphate fertilizer per plant cast0.2kg and nitrogen fertilizer0.1kg of N,P fertilizer mixture, Therefore, the young of Zenia insignis, Applying some N,P mixed fertilizer,can significantly promote Zenia nsignis Chun individual growth and development.
