摘　　要：为减少化肥使用总量,探寻有机肥对土壤理化性状的改善情况和对上海青产量的影响,以生物有机肥、矿源黄腐酸钾、腐植酸液体肥等有机类肥料为材料,在砂壤土上开展上海青的肥效试验。试验结果表明,与常规施肥相比,施用生物有机肥替代原5%总养分后减少15%化肥投入,可提高土壤养分含量,新模式TF增施矿源黄腐酸钾和腐植酸液体肥可使土壤有机质和速效钾含量分别显著提高11.2%和11.0%,并显著降低8.6%的土壤水溶性总盐含量;此外,该模式能显著提高上海青株高、叶片数,并使产量提升9.1%、综合效益提高9.9%。综上所述,施用有机类肥料可以有效提高土壤理化性状、上海青产量和效益。In order to reduce the total amount of chemical fertilizer,explore the effect of organic fertilizer on the improvement of soil physical and chemical properties and the yield of Brassica chinensis L.,the fertilizer effect test of B.chinensis L.on sandy loam soil was carried out with bio-organic fertilizer,mineral source potassium fulvate and humic acid liquid fertilizer as the materials.The experiment results showed that compared with conventional fertilization,the application of bio-organic fertilizer instead of the original 5%total nutrients and reduced 15%chemical fertilizer input could increase soil nutrient content.The application of mineral source potassium fulvate and humic acid liquid fertilizer in the new model TF could significantly increased the soil organic matter and available potassium contents by 11.2%and 11.0%,respectively,and significantly decreased the total water-soluble salt content in soil by 8.6%.Inaddition,this model could significantly improve the plant height,leaf number of B.chinensis L.,and increasing the yield by 9.1%and the comprehensive benefit by 9.9%.In summary,the application of organic fertilizers could effectively improve soil physical and chemical properties,the yield and economic benefit of B.hinensis L..
