黑土有机培肥与腐殖质特性

Organic Material Improving Soil Fertilzer in Black Soil and Humus Character

本文通过长期定位试验研究了施用猪粪及配施化肥对黑土腐殖质结合形态、组成及胡敏酸光学性质的影响。结果表明，施用猪粪能明显地增加腐殖质含量，提高腐殖质的松／紧比值和松／稳比值，并使胡敏酸的Δｌｏｇｋ升高，ＲＰ降低。单施化肥时上述作用不明显或相反。在本研究中猪粪配施化肥一般会削弱有机肥的上述作用，但其增产效果最佳。

This paper results showed that the application of pig manure evidently increased humus content,the ratios of looses-combined humus to tigh-combined and loose to stable of humus and the ΔlogK of humic acid, reduced it s RF.The effect of monoadding chemical fertilizer was not evident or contrary.Adding pig manure study, but the effect of increasing yield was most notable.
