摘　　要：为了找出厚荚相思人工林合理的追肥配方,以达到较佳经济效益,选用两种追肥配方和对照(不施肥),采用随机区组设计进行厚荚相思追肥试验。对4年的观测资料分析表明,不同追肥配方对厚荚相思树高、胸径、材积的生长均有一定促进作用,2006年追施A(复合肥500g/株+尿素200g/株+硼砂20g/株+有机肥280g/株)、B(复合肥800g/株+有机肥200g/株)两种肥料与对照相比,平均树高分别增加8.0%和5.8%;平均胸径分别提高7.8%和3.9%;平均单株材积分别增加22.7%和8.2%,其中A肥料的促进作用强于B肥料。The three kinds of fertilizer formula were selected to screen the reasonable fertilizer formula of Acacia crassicarpa plantation by randomized block design test. After four years observation, it showed that all the fertilizer formula had positive effect on tree height, diameter and volume. Compared with control A （Fertilizer 500g per strain ＋ urea 200g per strain ＋ borax 20g per strain ＋ organic manure 280g per strain） and B （Fertilizer 800g per strain ＋ organic fertilizer 200g per strain）, respectively increas 8.0% and 5.8% in height, 7.8% and 3.9% in diameter, 22.7% and 8.2% in volume in 2006; and A had stronger promotion than B.
