永济芦笋产区肥力现状及施肥建议

摘要

对永济芦笋产区土壤养分状况调查分析发现,芦笋田土壤有机质、碱解氮、有效磷和有效钾的含量均偏低,微量元素中锌、锰较缺乏.建议在永济芦笋田施肥中加大有机肥比例,注意化肥施用中氮、磷、钾三要素的平衡,同时改进施肥方式,提高肥料利用率.%The results of analysis to the soil nutrient features in asparagus fields in Yongji city demonstrated that soil organic matter and alkaline hydrolusis N, available P and available K were at low levels, and Zn and Mn contents at middle levels.So it was suggested that more organic fertilizer application is necessary; the balance of N, P, K in fertilizer should not be neglected and fertilizer utilization should be increased through improvement in the fertilization modes.
