2013年晋中市建设户用沼气14万户,大中型沼气集中供气工程28处、小型沼气工程44处,年产沼气3650万m3、沼液180万t、沼渣25万t,年增收节支约2.0亿元。但由于农村沼气的推广时间短,多数沼气用户只把它做为一种方便省煤的做饭工具,沼气效益只发挥了30%。2013年我市水果面积98.73万亩,产量20.3202达万t,为了在果园进一步拓宽沼肥综合利用范围,提高果农收入,生产出更多的无公害果品,因此,探讨沼肥在果园中的综合利用具有十分重要的现实意义。一、沼肥在果园中的应用1、沼液在葡萄上的应用据张天毅等人2011年在甘肃省高台县黑泉乡 In 2013, Jinzhong built 140,000 households of biogas, 28 large and medium-sized biogas plants and 44 small-scale biogas projects with an annual output of 36.5 million m3 of biogas, 1.8 million tons of biogas slurry and 250,000 tons of biogas residue, Day savings of about 200 million yuan. However, due to the short promotion time of biogas in rural areas, most biogas users only use it as a convenient and economical cooking tool, and the biogas benefit only takes up 30%. In 2013, the city’s fruit area was 987,300 mu with a yield of 20.3202 million tons. In order to further broaden the comprehensive utilization of biogas in the orchard, increase the income of fruit growers and produce more pollution-free fruits, Utilization has very important practical significance. First, the application of marsh manure in the orchard 1, the application of biogas slurry on the grape According to Zhang Tianyi et al 2011 in Gaotai County, Gansu Province, Black Springs Township
