摘　　要：为了探讨白浆土不同改良剂组合施用效果。在大田条件下,试验设7个处理,研究生物肥、有机肥和石灰对白浆土养分变化和大豆产量和品质的影响。结果表明：与常规施肥相比不同改良剂处理提高了大豆不同生育期株高、干物重,显著提高了大豆的粒数、荚数、但对百粒重影响不明显。不同改良剂施用提高了大豆产量,增产幅度为9.7%~25.6%,差异达到显著水平。提高土壤速效养分含量和pH值含量,改善土壤化学性状;提高大豆蛋白质和脂肪含量,改善大豆品质。不同改良剂混施效果好于单施。综合以上分析,白浆土上应用生物肥＋有机肥、石灰＋有机肥是比较好的改良剂组合。To investigate the application effect of different soil amendment combination of planosol, under fieldconditions, seven treatments were designed to study the effects of the biological fertilizer, organic fertilizer andlime on planosol nutrient change and yield and quality of soybean. The results indicated that： compared withconventional fertilization, treatment with different soil amendment improved the plant height, dry matter weightat different development stages of soybean, significantly improved the soybean grain number and number ofpod, but had no obvious effects on 100-grain weight. Different soil amendment application could improvesoybean production and the range of increase in yield was 9.7 % to 25.6 %, and the difference reachedsignificant level. The contents of soil available nutrient and pH were increased, soil chemical properties wereimproved; the soybean protein and fat contents were increased, and soybean quality was improved. Differentsoil amendment combination mixed application was better than single application. In conclusion, on the basisof the above analysis, biological fertilizer ＋ organic fertilize treatment and lime ＋ organic fertilizer treatmentwere goodsoil amendment combination.
