摘要
Taking 3 kinds of N,P,K compound fertilizers and P fertilizer as basal manure,the experiment was conducted in 3 levels.The results showed that in same level,various fertilizers had no evident different effects.The amount of fertilization could significantly affect the height increment of trees but did not significantly affect the diameter increment.By increase the application of organic fertilizer accompanied with chemical fertilizer,great difference was found in height increment and diameter increment among different treatments.The treatment 6 was the best in promoting branch growth and DBH increase of poplar.
