一、沼气资源的综合利用1、果树施用沼肥沼肥包括沼渣、沼液。沼渣含有机质36%～49.9%,腐殖酸10.1%～24.6%,全氮0.78%～1.61%,全磷0.39%～0.71%,全钾0.61%～1.3%。沼液中含有维生素B129.3mg/kg,维生素B116.42mg/kg,蛋白质1.43活力单位,纤维素酶7.65活力单位,生长素8.022mg/L,赤霉素3.510mg/L。果树施用沼肥后,不仅能满足树体生长所需的养分,而且能增加土壤中的的机质。如 First, the comprehensive utilization of biogas resources 1, the application of biogas marsh manure biogas residues, biogas slurry. Biogas residue contains 36% -49.9% of organic matter, 10.1% -24.6% of humic acid, 0.78% -1.61% of total nitrogen, 0.39% -0.71% of total phosphorus and 0.61% -1.3% of total potassium. The biogas slurry contains vitamin B129.3mg / kg, vitamin B116.42mg / kg, protein 1.43 activity units, cellulase 7.65 activity units, auxin 8.022mg / L, gibberellin 3.510mg / L. After the application of biogas in fruit trees, it can not only meet the nutrients needed for the growth of trees, but also increase the quality of the soil. Such as
