【摘要】 腐植酸是土壤有机质的重要组成部分，施用腐植酸生物有机肥能提高植物对有效物质的吸收效率，实现作物增产与土壤改良等多重功效。通过施用不同浓度的腐植酸生物有机肥，验证其对番茄生长、产量及土壤养分的提升效果。结果表明，80 kg/亩腐植酸生物有机肥(T2处理)效果最好。与施用常规肥料(T1处理)相比，T2处理的番茄株高增加8.96%、茎粗增加17.27%、花序数量增加18.18%、坐果率提高8.92%、植株干重增加13.24%、单果质量增加12.03%、单株产量增加16.09%、亩产量增加18.05%、亩产值增加32.80%，差异均达显著水平；土壤中有机质、全氮、速效磷含量分别显著提高12.25%、21.33%和11.46%，对土壤速效钾含量提高效果不明显。更多还原

【Abstract】 Humic acid is an important component of soil organic matter,and the application of humic acid bio-organic fertilizer can promote the absorption efficiency of nutrients by plants and achieve multiple benefits,such as increased crop yields and soil improvement.By applying different concentrations of humic acid bio-organic fertilizer,the effects on tomato growth,yield and soil nutrients was verified.The results showed that 80 kg/acre of humic acid bio-organic fertilizer (T2 treatment) had the best effect.Compared with the application of conventional fertilizers (T1 treatment),the tomato plant height increased by 8.96%,stem thickness increased by 17.27%,inflorescence number increased by 18.18%,fruit setting rate increased by 8.92%,plant dry weight increased by 13.24%,single fruit weight increased by 12.03%,single plant yield increased by 16.09%,yield per mu increased by 18.05%,and output value per mu increased by 32.80% in T2 treatment,with all changes showing statistically significant differences.The contents of organic matter,total nitrogen and available phosphorus in the soil increased significantly by 12.25%,21.33% and 11.46%,respectively,but the effect on increasing the content of available potassium in the soil was not significant.更多还原
