摘　　要：通过田间试验研究了腐殖酸肥不同用量(300、600、1 200、1 800 kg·hm^(-2))对番茄土壤微生物数量、番茄植株形态指标和果实产量品质等各项指标的影响。结果表明,与对照(CK蔬菜专用复合肥)相比,施用腐殖酸肥对各处理均有增产作用;腐殖酸肥施用量过高或过低都不利于产量品质的提高,适量腐殖酸肥的施用才能显著提高番茄经济效益;1 200 kg·hm^(-2)腐殖酸肥的追肥用量土壤微生物数量最多,植株生长状况最好,番茄产量品质最佳。In order to investigate the optimum fertilizer rate of humic acid fertilizer in the tomato production,field experiments were carried out to study the effect of humic acid fertilizer rates（300,600,1200,1800 kg·hm^-2） on soil microbial population,tomato plant morphological indicators,fruit yield and quality. The results showed that： humic acid fertilizer treatments had increasing effect compared to the control. Humic acid fertilizer was not conducive to the improvement of yield and quality at a higher or lower application rate. An appropriate amount of humic acid fertilizer can significantly improve the economic benefits of tomato. At the rate of 1200 kg·hm^-2,the soil microbial population showed the largest number,the plant growth condition,yield and quality was the best.
