摘要
根据“3414”试验结果，对水稻相对产量与土壤碱解氮、速效P、速效K含量进行方程拟合，以相对产量50％、50％-75％、75％～90％、90％～95％和大于95％为标准，得出了辽宁省不同地区水稻土壤有效养分丰缺指标。
The plentiful-lack index of paddy soil nutrient which was based on the ＂3414＂ test was built. Fitting equation was used by relative production of rice with alkali-hydrolyzable nitrogen, available P and K. The results showed that： when the relative production of rice is 50% ,50% -75% ,75% -90% ,90% -95% and more than 95%.
