摘　　要：以有机肥（猪粪）、化肥（尿素＋钾肥混合）作为基肥进行邓恩按造林试验，并以不施基肥进行对比。经过2年的试验，结果表明，施以猪粪作为基肥的标准地地径和树高平均生长量与对照两年均有极显著差异，以猪粪为基肥的标准地平均地径生长量为对照的4～5倍，平均树高生长量为对照的2～3倍，增效极其明显；而以混合的化肥为基肥的标准地地径和树高平均生长量与对照有一定增幅，当年生长量无显著差异，而第2年则有显著差异，地径和树高相比对照增幅在40％～98％之间。Using application of organic fertilizer （manure）, fertilizer （urea ＋ potassium mixture） as a base fertilizer for Eucalyptus dunnii reforestation tests and not application of base fertilizer for comparison. After two years of testing, the results showed that there were significant differences for average growth of diameter and tree height which application of manure for the compared two years. Using pig manure standard to the average basal diameter of 4 - 5 times to the contrast, the average tree height growth for the control of the 2 - 3 times, and the yield is very obvious. With a mixture of fertilizer as basal diameter of the standards, the average tree height growth and the growth rate of a certain control, growth was no significant difference, but there was significant differences at the following year. Comparing the diameter and tree height to the contrast, the increase is in between 40% -98%.
