摘要
本文研究了猪厩肥、鸡粪和钾化肥以不同比例配合施用对作物产量、土壤钾素含量及钾素利用率的影响。结果表明 ,2种粪肥与钾化肥配合施用与单施钾化肥或单施有机肥相比具有一定的优势 ,可促进作物对钾素的吸收 ,提高作物产量 ,提高钾素利用率 。
Effects of pig manure and chicken manure applied with K fertilize r in d ifferent ratio on crop yield,K content of soil, and K availability were studied. The results showed that K absorption of crop,crop yield, the utilization ratio o f K,rapidly available K and slowly available K content of soil under manure+K fe rtilizer were greater than those under manure or K fertilizer treatment.
