不同桉树专用追肥对桉树生长的影响
Effects of different specific topdressing fertilizers on growth of Eucalyptus
摘要
Abstract
[Objective]The purpose of this experiment was to study the effects of different specific fertilizers on Eucalyptus growth in Guangxi,select the most effective specific fertilizer for Eucalyptus growth,and provide therotical refer-ences for high yielding cultivation of Eucalyptus plantation. [Method]Single factor and complete randomnized block design was adopted to measure tree height,diameter at breast height (DBH),and average individual volume of tree in three top-dressing treatments with same nutrients rate (slow & long-acting fertilizer,specific fertilizer,and compound mixed fertilizer) for three consecutive years,in order to compare the effects of different fertizliers on Eucalyptus growth. [Result]One year after the first topdressing,tree height,DBH,and individual volume of tree in slow & long-acting fertilizer treatment were all superior to that of the other two treatments with extremely significant difference or significant difference. Six months after the second topdressing,tree height and average individual volume of tree in specific fertilizer treatment were higher than that of compound mixed fertilizer with significant difference. Slow & long-acting fertilizer was proved to be most effective in promoting Eucalyptus growth. [Conclusion]Under the same nutrients rate application,slow & long-acting fertilizer had more obvious promotion effect on growth than common specific fertilizer.关键词
