| 摘 要： | 大豆生育期内,土壤铵态氮含量与硝态氮含量变化相似,均为逐渐下降趋势。土壤基础肥力对土壤铵态氮含量具有决定性作用,种肥和追肥处理可以增加大豆生育期土壤铵态氮含量,对土壤硝态氮含量无明显影响。在大豆整个生育时期,土壤铵态氮与硝态氮含量呈极显著正相关(r=0.7988**),而土壤铵态氮、硝态氮与碱解氮间无明显相关性。

| Abstract: | The content of NH_4~+-N and NO_3~--N in the soil decreased during the growth period of soybean. Soil fertility determined the content of NH_4~+-N in the soil,the pop-up and dressing increased the content of NH_4~+-N during prophase,but had no significant effect on the content of NO_3~--N.The content of NH_4~+-N in the soil during the growth period of soybean were so positively correlated with NO_3~--N content in soil (r=0.7988~(**)) during the growth period of soybean,but there were no relativity among NH_4~+-N,NO_3~--N and available N. |
