沼液对酒用有机高粱产量和地力的影响试验结果表明：施用沼液原液、清粪水可使高粱穗粒数和千粒重增加，沼液原液比对照增产672.39 kg/hm2，增产17.55%，施用清粪水比对照增产596.27 kg/hm2，增产15.56%；同时增加了土壤有机质、全氮、碱解氮、有效磷和速效钾的含量，因此沼液能增强土壤肥力，改善土壤结构，但对pH值无影响。
沼液對酒用有機高粱產量和地力的影響試驗結果錶明：施用沼液原液、清糞水可使高粱穗粒數和韆粒重增加，沼液原液比對照增產672.39 kg/hm2，增產17.55%，施用清糞水比對照增產596.27 kg/hm2，增產15.56%；同時增加瞭土壤有機質、全氮、堿解氮、有效燐和速效鉀的含量，因此沼液能增彊土壤肥力，改善土壤結構，但對pH值無影響。

Test results of effect of biogas slurry on the yield and soil fertility of organic sorghum for wine showed that both the use of the original liquid of biogas slurry and liquid manure could increase the kernels per spike and 1000-grain weight of sorghum ,compared with the control group ,the increased yield by original liquid of biogas slurry was 672.39 kg/hm 2,17.55%higher than the control group ,while the increased yield by liquid manure was 596.27 kg/hm2,15.56%higher than the control group.The soil organic matter,total nitrogen,available nitrogen,available phosphorus and available potassium were also increased ,contributing to the enhancement of soil fertility and improvement of soil structure ,which had no effect on pH value.
