摘要
1985～1988年在河南农业大学农站进行了6种不同质地土壤施用有机肥料的盆钵试验。探讨了不同质地土壤上,有机物料对土壤腐殖质组成和氮素变化的影响及有机质的变化规律。结果表明,随施肥量的增加,腐殖质总碳、胡敏酸/富非酸及土壤C/N 比在各质地土壤中普遍增高;有机质和全氮含量也随施肥量的增加而变大。但是土壤的C/N 比,在3a 以后都下降至11.6左右,而趋于稳定。
The application of organic manure pot experiment was carried outin six kinds of different texture of soil at the experimental station during1985—1988.Effect of organic substance material on soil humus constitutionwith the law of nitrogen and organic matter variation on different texture ofsoil was treated.Results show that with the increased application rate ineach soil texture,the humus total—C,HA/HF ratio and soil C/N ratio rise;the content of total-N and organic matter becomes greater;the soil C/Nratios gradually reduce to near to 11.6 after three years of time and thencome to steadiness.
