摘要
沼渣是一种含多种营养成分的物质,对其应用效果及增产机理的研究对我国沼气产业的可持续发展具有重要的意义。通过肥料对比实验,本研究确定了施用沼渣肥和1/2沼渣+1/2鸡粪肥与目前常规的鸡粪肥和不施肥对照在促进黄瓜生长发育、提高黄瓜产量和改善土壤微生态环境等方面的作用。实验结果表明,与未施用沼渣的两个处理相比,施用沼渣能够提早黄瓜开花、延长黄瓜的结果时间、提高黄瓜产量,沼渣还能够改善土壤微生态环境,使土壤中细菌数量增加、真菌数量减少。
Biogas residue is a good fertilizer for it contains many nutrients. To study the application effect of biogas residue is important for the sustainable development of biogas industry in China. Through comparison experiments,the fertilizer efficiency of biogas residue was determined in this study,including the effect on cucumber growth and yield,and the microecological environment of soil. The results showed that the application of biogas residue could grow flowers in advance,extend the production period,and improve the soil micro-ecological environment comparing with the control without biogas residue application.
