沼气肥是一种量质兼优的完全肥料,既可作基肥,又可作追肥。一般渣肥作基肥,液肥作追肥更好。 1、沼气肥的施用方法:提倡深施,旱地作物采用窝施、沟施、然后盖土;水田采用犁沟深施(入土2—3寸),使泥、肥混合,提高肥料利用率。沼气池沉渣要堆沤一段时间后再施用,最好堆制成腐殖酸类肥料,用作基肥,效果更好。沼气肥的施用量要根据农作物各时期的需要,做到合理,经济施用,否则会出现作物徒长,行间荫蔽,花营脱落等现象,影响作物产量。
Biogas fertilizer is a good quality and complete fertilizer, both as a base fertilizer, but also for top-dressing. General residue for basal fertilizer, liquid fertilizer for top dressing better. 1, Biogas fertilizer application method: Advocate deep, dry crop using nest facilities, ditch facilities, and then cover the soil; paddy field using furrow (2-3 inches into the soil), so that mud, fertilizer and improve fertilizer utilization. Biogas digester sediment to be piled for some time after the application, the best heap made humic acid fertilizer, as a base fertilizer, the better. Biogas fertilizer application rate should be based on the needs of crops in different periods, so that they can be rationally and economically applied. Otherwise, such phenomena as leggy cropping, shade between rows, shedding flowers, etc. will affect crop yield.
