Effects of Humic Acid Fertilizer on the Growth of Maize and Wheat

采用田间试验方法,以兴农998和良兴99作为供试玉米和小麦品种,研究了腐植酸肥料对玉米和小麦生长发育的影响。结果表明,与施用普通复合肥相比较,腐植酸肥料的施用能显著减少玉米秃尖,提高养分,特别是提高氮、钾的利用效率,增产率达到10%以上;与等养分的普通肥料相比,腐植酸肥料的施用能促进小麦植株的个体发育和植株干物质的积累,促进小麦分蘖和后期成穗,小麦增产幅度达到了13.5%~18.7%。

Field experiments were conducted to study the effects of humic acid fertilizer on the growth of maize and wheat. Xingnong 998 and Liangxing 99 were the tested maize cultivar and wheat cultivar, respectively. The results indicated that, compared with the traditional fertilizer, humic acid fertilizer could significantly reduce the bare tip of maize, increase the nutrients use efficiency, especially nitrogen and potassium, and enhance the yield of maize by more than 10%. The results of wheat experiment showed that applying humic acid fertilizer could promote the individual development of wheat plant, dry matter accumulation, wheat tiller and fringe in the later growth stage. Therefore, the yield of wheat increased by 13.5%~18.7%.
