摘要
探究山药施用沼肥的效果,结果表明:与传统的施用化肥相比,沼渣作基肥或沼液作追肥施用不仅可以促进山药生长,而且可以极显著提高山药产量,且沼渣作基肥比沼液作追肥的效果要好。
Effects of biogas manure on yam were studied in this paper. The results indicated that, compared with the tradi- tional fertilization with chemical fertilizer, using biogas residues as basal dressing and biogas slurry as top dressing could not only obviously promote the growth of plants but also increase tuber yields, and that the efficiency of biogas residues used as basal dressing is better than that of biogas slurry used as top dressing.
