为探索桉树不同时期施肥的效应及其对桉树人工林生长的影响,为桉树人工林施肥增产提供参考,本文选取2年生巨尾桉萌芽林,以施肥量0.5kg/株,设置了不同时期4种不同施肥措施,调查了施肥当年和第二年桉树萌芽林生长量及其经济效益。结果显示:不同时期施肥对桉树林木生长量有不同程度的影响,除了不施肥和1、6月底2次施肥的树高生长差异显著,其余差异均不显著。估算不同时期施肥经济效益表明,净收入大小排序为:5月底施肥>1月底施肥>不施肥>1、6月底各施肥1次由此可建议,每年施1次肥,施肥时间为1月底。
In order to explore the effects of fertilization on Eucalyptus and its effects on the growth of Eucalyptus plantations, this paper provided reference for fertilization and yield increase of Eucalyptus plantations. In this paper, 2-year-old Eucalyptus camaldulensis sprout seedlings were selected to fertilize 0.5kg / Different fertilization measures were used to investigate the growth of eucalyptus sprouting forest and its economic benefits in the year and the second year of fertilization. The results showed that fertilization at different periods had different effects on the growth of Eucalyptus trees, except for no fertilization and significant differences in tree height growth between the two fertilizations at the end of June and the end of June. Estimation of economic benefits of fertilizer application in different periods showed that the order of net income was: fertilization at the end of May> fertilization at the end of January> no fertilization> application of fertilizers at the end of 1 and 6, which suggested that fertilizer should be applied once a year and fertilization time should be the end of January.
