摘要
分析土壤全氮及其各种形态氮的含量是评价土壤肥力和合理使用氮肥的主要依据.本试验对辽东地区土壤全氮含量的分析结果表明,全氮含量从高到低的顺序依次为:草河口,牦牛坞,五龙背,合隆,刘家河.对全氮含量较低的地区应适当提高氮肥的使用来改善土壤的肥力.
The analysis of total and the other forms of nitrogen has become the major basis of fertility evaluating and rational utilization. By analyzing the total nitrogen in soil in the east Liaoning Province. For the regions with lower nitrogen, the dosage of nitrogenous fertilizer should be increased in order to improve the soil fertility.
