无机肥料配合腐植酸铵、复硝酚钠对玉米生长的影响

The Impact of Inorganic Fertilizer Combinated with Humic Acid Ammonia and Sodium Nitrophenolate on Corn Growth

通过盆栽试验,研究了无机肥料配合腐植酸铵及不同浓度的复硝酚钠对玉米株高、叶面积、地上生物量干重、全氮全磷全钾总含量的影响。结果表明,无机肥料与腐植酸铵配合使用比单独使用无机肥料效果要好,能明显增加玉米株高2.45%、叶面积4.86%、地上生物量干重5.75%、全氮4.1%、全磷9.25%、全钾5.43%;无机肥料与腐植酸铵和复硝酚钠配合使用比单独使用无机肥料效果更好,能明显增加玉米株高6.58%、叶面积10.99%、地上生物量干重13.62%、全氮9.92%、全磷15.03%、全钾12.14%;复硝酚钠在玉米肥料上的添加浓度按0.2%最好。

A pot experiment was conducted to investigate the effect of inorganic fertilizer combinated with humic acid ammonia and sodium nitroohenolate on corn growth and nutrients absorption. The results showed that the plant height, leaf area, dry weight of aboveground biomass in treatment with applying inorganic fertilizer and humic acid ammonia were significantly increased by 2.45%, 4.86%, and 5.75% than those in treatment with only applying inorganic fertilizer, respectively, and the contents of total N, P and K were increased by 4.1%, 9.25% and 5.43% respectively. The effect of inorganic fertilizer combinated with humic acid ammonia and sodium nitroohenolate on corn growth and nutrients absorption were more significant, which increased the above index by 6.58%, 10.99%, 13.62%, 9.92%, 15.03% and 12.14%, respectively. The optimum dosage of sodium nitrophenolate was 0.2%.
