摘　　要：为探讨沼肥在大豆上的合理施用技术,采用田间试验,研究沼肥对大豆产量、品质、养分吸收利用及土壤化学性质的影响。结果表明:与习惯施肥处理相比,100%沼渣、30%沼渣+化肥、20%沼渣+化肥处理的大豆产量分别增加1.02%,10.48%,0.16%;大豆粗脂肪含量分别增加2.31%,2.70%,5.07%;磷肥利用率分别增加5.04%,23.39%,8.60%;土壤有机质含量分别升高13.39%,3.68%,0.50%;20-80 cm土层内土壤硝态氮、铵态氮含量降低幅度分别在13.70%～61.56%,15.98%～70.10%之间。说明试验条件下,无论沼渣单施还是沼渣与化肥配施均可提高大豆粗脂肪含量、磷肥利用率、土壤有机质含量,降低氮素的流失。To research into the suitable using technology of biogas slurry on soybean, field experiment was applied to investigate the effects of biogas slurry on soybean yield, quality and nutrient absorption and soil chemical property. The results showed： The soybean yield treated with 100% biogas-residue, 30% biogasresidue＋chemical fertilizer and 20% biogas-residue＋chemical fertilizer were increased by 1.02%, 10.48% and 0.16% respectively than that treated with traditional fertilization; The soybean crude fat content increased by 2.31%, 2.70% and 5.07% respectively; Phosphorus fertilizer utilization increased by 5.04%, 23.39% and 8.60% respectively; Soil organic content increased by 13.39%, 3.68% and 0. 50% respectively; Soil nitrate content in 20-80 cm decreased by 13.70% to 61.56%. Soil ammonium nitrogen decreased by 15.98% to 70.10%It suggested that either the biogas residue used by single or it was used combined with chemical fertilizer, the soybean crude fat content, phosphorus fertilizer utilization, soil organic content were increased, and the nitrogen losing was reduced.
