通过研究不同沼肥方式对桉树生长量和土壤肥效的影响结果表明:表现最好的为处理8,4年生桉树其平均胸径、平均树高、平均材积分别为14.10cm、17.37m、0.126 2cm3,比处理1、处理2、处理3、处理4分别增加14.35~22.61%、5.85~11.70%、33.83~60.15%;比总体平均分别增加13.98%、6.04%、30.37%;胸径树高材积均达到差异极显著。沼肥与化肥混施可增加土壤有机质,提高土壤中氮、磷、钾的含量。在桉树追肥时采用每次每株施用沼肥5kg+复合肥250g效果较好。
The effects of different biogas manure on the growth of eucalyptus and soil fertility were studied. The results showed that the best performance was that the average DBH of average tree height and average tree height of 8 and 4 year old eucalyptus were 14.10cm, 17.37m and 0.126 2cm3, Which increased by 14.35 ~ 22.61%, 5.85 ~ 11.70% and 33.83 ~ 60.15% respectively than that of treatment 1, treatment 2 and treatment 3 and treatment 4; increased by 13.98%, 6.04% and 30.37% significant. Mixed biogas fertilizer and fertilizer can increase soil organic matter, increase soil nitrogen, phosphorus and potassium content. In the eucalyptus topdressing each application of biogas 5kg + 250g fertilizer is better.
