摘要： 为了促进腐殖酸资源在农业生产上的合理利用，缓解中国有机肥源不足的问题，通过小区试验，研究了不施肥、施化肥、风化煤与化肥配施、腐殖酸有机肥对玉米植株性状、干物质积累、籽粒产量、养分吸收量及肥料利用率的影响。结果表明，不同施肥措施均能显著改善玉米植株生长，促进玉米干物质积累，提高籽粒产量及养分吸收量；风化煤与化肥配施、腐殖酸有机肥较单施化肥显著改善了玉米生长，增加了根重、秸秆重、籽粒产量，提高各部位氮磷含量及氮磷肥的利用率；风化煤与化肥配施、腐殖酸有机肥还能促进植株对钾的吸收，显著提高根系和秸秆中钾含量，对籽粒中钾含量的影响不显著。

Abstract: In order to use humic acid efficiently in agriculture so as to alleviate organic fertilizer shortage, a field experiment was set up to study the effect of different fertilization, including no fertilizer, fertilizer, fertilizer combined with weathering coal, humic organic fertilizer on crop growth, dry matter accumulation, yield and fertilizer use efficiency of maize. The results showed that: crop growth, dry matter accumulation, yield and nutrient uptake were improved significantly by different fertilization; compared with applying fertilizer, fertilizer combined with weathering coal and humic organic fertilizer not only improved crop growth and increased the weights of root, stalk and grain yield significantly, but also increased the content of nitrogen and phosphorus in each part of maize, resulting in higher fertilizer use efficiency. Fertilizer combined with weathering coal and humic organic fertilize increased the potassium content in root and stalk significantly, however, they had no significant effect on the potassium content in grain.
