摘要

采用盆栽试验

研究施用动物粪便、动物残体、草本残体、木本残体5年后对黑土胡敏酸(HA)、富里酸(FA)和胡敏素(HM)元素组成的影响。结果表明:与CK相比

有机物料施用5年后

黑土HA的C、H含量均显著降低

而缩合度及含氮基团数量提高

并以木本残体作用最显著。除动物粪便处理HA的N含量与CK的大致相同外

其余有机处理N含量均显著提高

各处理HA的O含量由大到小依次为木本残体>草本残体>动物粪便>CK>动物残体

且各处理差异显著。有机物料的施用可以降低FA的缩合度

并以草本残体作用最显著

同时草本残体施用提高了FA的N含量。而动物残体使FA的H含量显著降低。有机物料FA的C含量表现为草本残体>木本残体>CK>动物残体>动物粪便

而O含量及氧化度由大到小依次为动物残体>动物粪便>CK>木本残体>草本残体

且各处理间差异显著。有机物料的施用使HMi的C、H含量下降而使O含量上升

并以草本处理作用最显著

同时草本处理也使HMi的N含量降低。施用有机物料使HMc的氧化度、芳香度提高

结构变复杂。

Abstract

The pot experiment was conducted to study the effect of animal excrement

animal remnant

herb residues and woody residues on elemental composition of humic acid(HA)

fulvic acid(FA) and humin.The results showed as follows: Compared with control treatment(CK)

after five years

application of organic materials resulted in significant decrease of carbon(C) and hydrogen(H)

but enhanced condensation degree and content of nitrogen containing group

and the role of herb residues was the most obvious.Apart from animal ...
