| 摘 要： | 2008年通过对浙江省青紫泥田、黄斑田、黄泥砂田、洪积泥砂田四大水稻土土属的农田地力调查，结合第二次土壤普查时期土壤养分资料，探讨了浙江省农田土壤养分的变化规律。结果表明，土壤pH明显下降，急需调节改善。土壤有机质整体水平较高，变化不明显。有效磷含量大幅上升，且不同土属之问差异较大。速效钾含量显著提高，但农田土壤缺钾现象仍十分普遍。

| Abstract: | The changes of soil nutrition status in Zhejiang province were studied through the investigation of field capacity of four diferent type soils(blue clayey paddy soil，silt-clayey yellow mottled paddy soil on fluvimarine deposit，paddy field onredeposit of red soil and diluvial gitty loamy paddy soil)in 2008，combined with the soil nutrition census data acquired from the Second National Soil Survey．The results showed that soil pH decreased obviously，which was in need of adjustment．The level of soil organic matter was higher without significant changes．The content of available-P markedly increased，and there were great diferences among diferent soil types．The content of available-K increased significantly as well，but the K-deficiency Was still very common in farmlands． |
