摘要
采用单因素随机区组设计,对比了几种不同桉树复合肥(硫酸造粒肥、水蒸气造粒肥、有机-无机肥、有机-无机肥+微生物菌剂、红鹰肥)对桉树生长的影响。结果表明各施肥处理1.5年生树高比CK增加9.30%~23.67%;2.0年生胸径比CK增加13.28%~18.96%;2.0年生桉树单株材积比CK增加38.86%~64.41%。各处理间桉树树高、胸径、材积影响大小顺序均为有机无机肥+微生物菌剂〉水蒸气造粒肥〉有机无机肥〉硫酸造粒肥〉红鹰肥〉CK。因此,有机-无机肥与微生物的配合施用可有效提高肥料利用率,促进桉树的生长。
A single factor randomized block design was adopted to study on the influences of growth of Eucalyptus trees by u- sing different Eucalyptus compound fertilizers( treatment of A, sulfuric acid granulated fertilizer; B, steam granulated fertil- izer ; C, organic-inorganic fertilizer; D, organic-inorganic fertilizer + microbial agent; E, Hongying fertilizer). The tree height of all treatments at 1.5 years old were 9.30% -23.67% higher than that of the CK; The DBH of all treatments at 2 years old were 13.28% - 18.96% larger than that of the CK; The tree volume of all treatments at 2 years old were 38.86% -64.41% larger than that of the CK. The order of treatments' influences on both tree height, DBH and volume of Eucalyptus was D 〉 B 〉 C 〉 A 〉 E 〉 CK. Therefore, organic-inorganic fertilizer + micro-organism can effectively improve utilization rate of fertilizer and promote the growth of Eucalyptus.
