摘要
对桉树幼林进行不同形态追肥试验,结果表明:对于提高土壤中全量和速效N、P、K的含量、土壤中量(Ca、Mg)和微量元素(Cu、Zn、B)的含量,颗粒态追肥比粉状追肥好,且高浓度颗粒态肥效果最好,并能有效就缓解追肥带来的土壤酸化作用。
Tests of different top-dressing modes were made in young eucalyptus plantation.It was concluded as follow： the effect of dressing granular fertilizer was better than that of the dressing powder fertilizer if increasing the concentration of N,P,K,Ca,Mg,Cu,Zn and B,high concentration of granular fertilizer had the best effect and was effective to alleviate the effect of soil acidification caused by top-dressing.
