摘要

采用田间试验和化学分析方法．研究了3种缓释复合肥对覆膜早作水稻生长、产量、叶片氮素形态、氮肥利用率和稻米品质的影响。结果表明．施用高氮型无机型缓释复合肥（SRF1）条件下，覆膜早作（DF）水稻植株生长、产量、氮素营养和稻米品质优于常规淹水栽培（CF），DF和CF的氮肥表观利用率分别为64．90％和37．15％。同为覆膜早作时．施用高氮型有机无机缓释复合肥（SRF1）的水稻农艺性状、产量及分蘖期和孕穗期植株叶片氨基酸、NO2^- -N含量较高，而植株叶片蛋白氮和全氮含量以高氮型无机缓释复合肥处理（SRF1）较高，氮肥表观利用率和农业利用率均以SRF2〉SRF1〉SRF3，氮肥生理利用率差异不大。覆膜早作和施用缓释复合肥能提高稻米营养品质，稻米氨基酸和蛋白质含量与水稻分蘖期叶片的蛋白氮和全氮含量皆呈显著正相关。
