| 摘 要： | 通过淹水植稻试验，研究了几种有机－无机复混肥肥料氮的有效性及影响因素．结果表明：含不同有机物料（木薯渣、人粪渣、泥炭和花生麸）的有机－无机复混肥肥料氮的有效性不同：有机物料能够延缓前期肥料氮的释放，促进中后期水稻氮素的供应；不同有机物料对水稻氮素供应的影响亦有不同；有机物料的组分是影响有机－无机复混肥肥料氮有效性的主要因素之一．

| Abstract: | Pot experiment of paddy rice was conducted to study the nitrogen availability of organo-inorganic complex fertilizers and its affecting factors. The results indicate that the nitrogen availability of organo-inorganic complex fertilizers varies with the composition of organic materials (cassava residue, feces, peat and peanut bran cake), the organic materials can reduce the release of nitrogen during the early period and increase the supply of nitrogen during the medium and later period.Effects of organic materials on nitrogen supply are different. The composition of organic materials is one of the main factors to affect the nitrogen availability of organo-inorganic complex fertilizers. |
