| 摘 要： | 根据20年定位试验的资料，研究了稻田土壤施和不同肥料，N、P、K养分在剖面中的分布特征。结果表明：有机肥和化肥配施土壤全N和碱解N在整个剖面比单施化肥均有增加，但增加量主要集中在耕层；而有效磷只在耕层比单施化肥有明显的增加；有机肥和化肥对钾移动的影响基本一致。

| Abstract: | Based on twenty years′ experiments, the study analyses the profile characters of the N、P、K nutrient in rice fields after application of different fertilizers. Comparing with which from aplication of only inorganic fertilizers, the quantity of total－nitrogen and available nitrogen of the soil profile from mixed application of organic and inorganic fertilizers increased. The increasing quantity was mainly on the cultivated horizon. Only the increasing quantity of the available phosphorus on the cultivated horizon was marked. The influence of organic fertilizers on potassium shifting was the same as that of chemical fertilizers. |
