| 摘 要： | 施用腐殖酸生物活性肥料对冬小麦生长和土壤微生物活性的试验结果表明,于等量无机养分水平下,施用腐殖酸生物活性肥料冬小麦群体发育平稳,改善植株性状明显,增强抗逆性能。与施用无机复混肥和习惯施肥处理相比,施用腐殖酸生物活性肥料,冬小麦穗长分别增加0.4和0.5cm,旗叶面积分别增加0.7和1.1cm2,次生根条数分别增加1.3和2.2条。产量构成因素中有效穗数,穗粒数和千粒重施用生物活性肥处理也明显高于无机复混肥和习惯施肥,其产量分别增加9.0％和15.2％,差异达显著水平。同时腐殖酸生物活性肥料能够促进土壤有益微生物繁衍,使土壤微生物数量明显增加,提高土壤脲酶、蔗糖酶、磷酸酶和过氧化氢酶活性,对提高肥效,增强土壤肥力,改善作物营养环境有一定作用。

| Abstract: | An experiment was conducted to study the effect of humic bio-active fertilizer application on the growth of winter wheat and soil microbial activity. The results indicated that under the equivalent level of inorganic nutrition, winter wheat population grew steadily with the application of humic bio-active fertilizer, meanwhile the application of bio active fertilizer distinctly improved plant characters and enhanced plant resistance ability to adverse circumstance. Comparing the application of humic bio-activity fertilizer and inorganic compound and traditional fertilization, spike length increased 0.4 and 0.5 cm, flag leaf area increased 0.7 and 1.1cm2, and second root number increased 1.3 and 2.2, separately. For the treatment of humic bio-active fertilization, the effective spike, grain per spike and 1000-grain weight, which were constitution factors of yield, were notably higher than inorganic compound fertilization and traditional fertilization. The amount of increase in yield for humic bio-active fertilization and inorganic compound fertilization were 9.0% and 15.2% separately comparing to the traditional fertilization with the difference being significant. Meanwhile, the application of humic bio-active fertilizer could promote the multiplication of soil beneficial microorganism, cause the quantity of soil microbial population obvious increase, enhances activities of soil urease, the sucrase, the phosphatase and hydrogen peroxidase. It also had a certain function on the promotion of the fertilizer efficiency, the enhancement of soil fertility and the improvement of crops nutrition environment. |
