一、沼液、沼渣在种植业上的综合利用 1.沼肥的施用。沼液中含有水溶性的氮、磷、钾等速效营养成分。沼渣中含有较全面的养分和丰富的有机质,具有改良土壤的作用。沼渣宜作基肥,沼液宜作追肥。沼渣作基肥一般亩用量2500公斤左右。沼液作追肥可以直接施入土壤中,也可以作叶面喷施。作叶肥施用时应选正常发酵沼气池的沼液,一般用纯沼液,但在夏天气温高时应适当对水,于早晚喷施。
First, biogas slurry, biogas residue in the comprehensive utilization of plantation 1. The application of biogas. Biogas slurry containing water-soluble nitrogen, phosphorus, potassium and other quick-acting nutrients. Biogas residue contains more comprehensive nutrients and rich organic matter, with the role of soil improvement. Biogas residue should be used as basal, biogas slurry should be topdressing. Biogas residue for the general amount of mu 2500 kg. Biogas slurry for topdressing can be applied directly to the soil, can also be used as foliar spray. For foliar application should be selected normal fermentation biogas digesters, generally with pure biogas slurry, but in the summer when the temperature should be appropriate for the water, spraying in the morning and evening.
