This paper reports a study in tie inhibitory effect of biogas fluid on plant pathogenic microorganisms. Eleven microorganism strains are selected and the antim-icrobial tests in the laboratory are done by the cup dish method.It is found that no matter what the biogas fluid is gasproducing or the gas production is finished, the inhibitory microorganism action is all occured on most plant pathogenic microorganisms, but their antimicrobial effects are different on various microorganisms. The inhibitory effects are relative strong on Rhizoctomia solani, Helminthosporium sativum, slightly poor on Helminthosporium turcicum, Helminthosporium maydis, Colletotrichum gossypii, Helminthosporium sigmoideum:relatively poor on Fusarium oxysporum f. vasinfectum, Fusarium avenaceum var. fabae. However, on Monilia fructigena, Fusarium SP, the biogas fluid not only has no inhibitory action, but also has a little effect to stimulate growth.The test shows that the antimicrobial effect of pH7 2 biogas fluid is better than that of pH6.4. The antimicrobial action is retained in biogas fluid by excluding bacteria from biogas fliud with bacteria filter or the fluid is exposed to sunshine over 6 hours.

本文介绍了沼液对植物病菌作用的研究,采用11种常见植物病菌,用实验室杯碟法进行抑菌试验。发现不管正在产气或已停止产气的沼液对大部分植病菌都有抑制作用,但其抑茵效果有差异:对小麦根腐病菌、水稻纹枯病菌抑菌效果较明显,稀释成10%浓度的沼液也有明显的抑菌圈;对玉米大斑、玉米小斑病菌、小球菌核病菌、棉花炭疽病菌等效果差些;对蚕豆枯萎病菌,棉花枯萎病菌等更羞些,浓度在50%以上才看到有抑菌现象;而沼液对苹果褐腐病菌、镰刀菌不仅没有抑菌作用,而且还有刺激生长现象。实验还证明了pH6.4的沼液抑菌效果不如pH7.2的;除去菌体和日光下曝晒6小时以上的沼液仍有抑菌效果。

The results showed that the net fish yeilds for the ponds fed only with slurry digested and with chicken manure were 12,120 kg/ha and 3,412.5 kg/ha respectively. The net profit of the former has increased by 2.5 times as compared with that of the latter.The reasons why fish culture with slurry digested can increase fish yield so obviously had been examined by authors through analysis of input-output...

The net profit of the former has increased by 2.5 times as compared with that of the latter.The reasons why fish culture with slurry digested can increase fish yield so obviously had been examined by authors through analysis of input-output of energy, N, P and biomass of plankton as well as the changes of DO in fish poud.And they suggested that it is an effective way to raise utilization rate of waste resources and to promote the further development of biogas digester system in rural areas by means of liquid slurry digested to culture fish.

本文对纯沼液和纯鸡粪养鱼进行了比较研究。结果表明,纯沼液养鱼每亩的净产量达808kg,纯鸡粪养鱼的净产量每亩只有227.5kg。前者的经济效益要比后者高2.5倍。作者从能量、氮和磷的投入产出、水体中浮游生物的含量以及溶解氧的变化情况等方面分析了增产的原因。通过试验,作者指出,沼液养鱼是提高农村废弃物资源的利用率和推动沼气的进一步发展的有效途径。

By means of the anaerobic technique,using mushroom residues as raw materials to elucidate the relationship between the functional bacteria distribution and biogas production rate during the biogas fermentation Was studied. It is found that in the first stage of the fermentation process, the acid-producing bacteria dominate the digest system, wheras the major microbes in the second(middel) stage are cellulolytic bacteria, and in the last stage, the number of methane-producing bacteria is slightly...

By means of the anaerobic technique,using mushroom residues as raw materials to elucidate the relationship between the functional bacteria distribution and biogas production rate during the biogas fermentation Was studied. It is found that in the first stage of the fermentation process, the acid-producing bacteria dominate the digest system, wheras the major microbes in the second(middel) stage are cellulolytic bacteria, and in the last stage, the number of methane-producing bacteria is slightly higher than in the first stage. In view of methane production the mushroom residues may be better than rice-strow as raw materials for biogas fermentation.
