摘要
通过盆栽实验,研究腐植酸与硅肥配施对土壤养分的影响。结果表明,施肥量高的处理,提高了土壤养分中的有效硅、水溶性钙、速效钾、有机质含量,碱解氮、速效磷的含量,各种养分含量随着施肥量增加而提高;腐植酸可增加硅肥的有效性。腐植酸与硅肥施肥量均达0.8g/kg时,土壤中各种有效养分含量最高。腐植酸与硅肥配施较二者单独施用时效果好。
A pot experiment was conducted to investigate the effect of humic acid and silicon application on soil fertility. The results showed that the contents of available silicon, water soluble calcium, available potassium and organic matter were all increased with increasing fertilizer dose. The application of humic acid could increase the effectiveness of silicon fertilizer. The highest contents of soil available nutrients were obtained under the condition of applying 0.8g/kg humic acid and silicon, respectively. Meantime, the combation of humic acid and silicon exhibited a synergistic effect than ap- plying silicon or humic acid alone.
