| 摘 要： | 采用田间试验及人工渗滤池试验方法,研究了土壤中硝态氮含量的影响因素。结果表明,影响大田土壤中硝态氮因素很多,程度不一,其中土壤类型决定着硝态氮基础含量,是内因,而施肥及施氮量是影响硝态氮含量最大的外界因素,其次是土壤湿度和氮肥品种,土壤温度对其影响不明显。

| Abstract: | An experiment in field and artificial penetration-filter pond test both were conducted to show factors affecting content of nitrate-nitrogen in soil in the present study. It has been discovered that there existed many factors affecting nitrate-nitrogen content in soil. Type of the soil studied played a determined role in influencing the nitrogen content, while fertilization and amount of the fertilizer applied were found to be a most external factor in affecting the content. In addition, humidity of soil and variety of fertilizers applied played a limited function, while temperature of soil had little effect on the content. |
