摘 要 ：床土培肥是培育水稻机插秧苗的首要措施。在不同类型床土条件下对培肥水平与床土速效氮磷钾增加的关系及育秧过程中的肥力消耗进行了分析。结果表明，通过添加速效肥料进行床土培肥，可使床土速效NPK含量迅速增加，速效氮的增加呈指数关系，高培肥处理的增幅大于低培肥处理，丘陵土的增加快于冲积土；速效磷含量随培肥水平的

Abstract:Seedbed soil fertilizing is one of the key measures for rising mechanical transplanting rice seeding. The relationship of fertilizing levels to the increase of available N, P, K in seedbed soil and their uptake during seedling growth were analyzed, using alluvial soil and hill-paddy field soil as se
