沼气发酵残留物已对农田普遍发生的近 30种病害具有防治作用 ,至少有 2 0多种病害的防治效果达到或超过了现行使用的农药效果 ;在虫害方面 ,沼气发酵残留物对 19种虫害取得明显的防治效果。利用沼气发酵残留物既可防治作物病虫害 ,而且还起到较好的肥效作用 ,是发展绿色农业、避免农药污染的理想方法。在抑制病原菌的研究方面 ,沼气发酵残留物对大肠杆菌、副伤寒杆菌和猪丹毒杆菌等致病菌有显著抑制作用 ,对十株青霉和曲霉有不同的抑制效果 ,对 17种农作物病原菌有不同程度的抑制作用。长期使用沼气发酵残留物这种“农药”,不会对环境带来污染 ,也不会产生病虫害的抗性等问题。
Biogas fermentation residues have been used to prevent and control nearly 30 kinds of diseases occurring in farmland. At least more than 20 kinds of diseases have reached or exceeded the pesticide effect of the existing ones. In terms of insect pests, Obtain obvious control effect. The use of biogas fermentation residue can prevent crop pests and diseases, but also play a better fertilizer effect, is the development of green agriculture, to avoid pesticide contamination the ideal way. In the inhibition of pathogen research, biogas fermentation residues on Escherichia coli, paratyphoid bacilli and Erysipelas bacteria and other pathogenic bacteria have significant inhibitory effect on ten strains of Penicillium and Aspergillus have different inhibitory effects on 17 kinds of crop pathogens are Different degrees of inhibition. Long-term use of biogas fermentation residues of this “pesticide”, will not bring pollution to the environment, it will not produce pests and diseases and other issues.
