| 摘 要： | 对甘肃省几种主要耕种农田土壤肥力连续5年的定位监测结果进行分析。结果表明:农田土壤耕层有机质、全氮、速效磷均比第二次土壤普查值增加,速效钾均比普查值下降;施肥结构不合理,土壤耕层养分盈亏量为氮盈余,磷富积,钾亏缺。

| Abstract: | Soil fertility of several main farming fields was detected successively for 5 years in Gansu, and it was carried out in oriental fields. It showed that the organic matter, total N and soluble P were higher than that of the second inspection. However, the soluble K was reverse. The structure of application was unreasonable. There were N sufficient and K deficient in tillage layer. |
