| 摘 要： | 采用间歇淋洗好气培养法研究了东北黑土中氨基酸的矿化过程以及添加葡萄糖和葡萄糖与氮肥配施对其质量分数的影响。结果表明：土壤中氨基酸质量分数的变化受到外源物质添加的影响。与对照处理相比,葡萄糖以及葡萄糖与氮肥配施均能促进土壤氨基酸质量分数的积累,并且2种外源物质对氨基酸质量分数的影响相差不多。土壤不同种类的氨基酸具有不同的矿化特征,其中异亮氨酸的矿化速率最快,其次是赖氨酸、缬氨酸、组氨酸和亮氨酸,而精氨酸、甘氨酸和酪氨酸矿化速率较低。此外,土壤中每种氨基酸矿化对总氨基酸矿化的贡献与其在土壤中的质量分数有关,一般来说,氨基酸质量分数高则其矿化的贡献也大。

| Abstract: | By the method of intermittent leaching aerobic incubation,this paper studied the mineralization of amino acid in black soil of Northeast China,and the response to glucose addition and glucose plus nitrogen amendment.The results showed that,compared with the control treatment,both glucose addition and glucose plus nitrogen amendment improved the content of amino acid,and the effects of these two treatments were similar with each other.The mineralization characteristic of amino acid was compound-specific.For ... |
