近年来国内外化肥生产正朝着高效复合肥料的方向发展。腐植酸类肥料的品种也日益增多。腐植酸氮、磷、钾就是一种新型腐植酸复合肥料(下面简称复合腐肥)。我们在1976年开始进行腐铵肥料试验的基础上,从1979至1981年,又在红壤上进行复合腐肥与无机氮、磷、钾复合肥(下面简称无机复合肥)的对比试验,以了解复合腐肥的改土,增产效果。现将初步试验结果报道如下:
In recent years, domestic and international fertilizer production is moving in the direction of efficient compound fertilizer. Humic acid fertilizer varieties are also increasing. Humic acid nitrogen, phosphorus, potassium is a new type of humic acid compound fertilizer (hereinafter referred to as compound fertilizer). Based on the trial of the ammonium fertilizers in 1976, we conducted a comparative experiment between compound fertilizers and inorganic nitrogen, phosphorus and potassium compound fertilizers (hereinafter referred to as inorganic compound fertilizers) on red soil from 1979 to 1981 to understand Compound fertilizer to soil improvement, increase production. Now the preliminary test results are reported as follows:
