不同工艺桉树肥料基肥对一年生桉树生长的影响

Comparison on Annual Grwoth Eucalyptus Using Different Kinds of Special Fertilizer as Based Fertilizer

以桉树为试材,采用单因素随机区组设计,对比研究了几种不同工艺桉树肥料（蒸气肥、硫酸肥、包衣缓释肥、林场自制无机肥和有机-无机肥）及活性肥对桉树生长的影响。结果表明：对桉树施用不同工艺桉树肥料作基肥,其对桉树促进作用胸径比不施肥CK增加了4.00%～12.86%,树高比CK增加了4.40%～16.47%;材积比CK增加了11.50%～38.56%。而不同生产工艺肥料对桉树生长的促进作用不同,蒸气肥与硫酸肥对桉树树高促进作用较明显,包衣肥对桉树胸径促进作用较明显,而有机-无机肥能较好的促进桉树材积的积累;在施用桉树专用无机肥的同时配施活性肥,能更好的促进桉树生长,但过量施用活性肥反而会抑制桉树生长。

Taking Eucalyptus trees as test material,the effect of Eucalyptustrees growth by using different basal fertilizers of Eucalyptus（steam fertilizer,acid fertilizer,coating fertilizer,fertilizer produced by a forestry center and organic-inorganic fertilizer）were studied,in order to provide some bases for applying fertilizer of Eucalyptus.A single factor randomized block design was adapted to study between several different Eucalyptusspecial fertilizers and the active fertilizer.The results showed that applied different special fertilizer as based fertilizer could promote the diameter at breast height of Eucalyptus increased 4.00%-12.86% than the non-fertilized CK;tree height increased 4.40%-16.47%than CK;volume increased 11.50%-38.56%than CK.Steam fertilizer and acid fertilizer could better promote the growth of tree height,coating fertilizer could advance the growth of DBH obviously,organic-inorganic fertilizer could improve volume accumulation.Applied Eucalyptus special inorganic fertilizer with activity of fertilizer could better promote the growth of Eucalyptus,but it would inhibit the growth of Eucalyptus with excessive application of active fertilizer.
