摘　　要：用田间小区试验的方法，对抛秧栽培条件下的施肥技术进行了研究。结果表明在其它条件相同情况下，与常规插秧栽培相比抛秧水田减少基肥氮肥用量２０％和分蘖肥３２％可获得更高产量，即抛秧栽培应控制前期氮肥用量。in this kind of cultivation, higher yield was obtained in plots when the basic nitrogen decreased to 20%than that used in normal transplant, and decreed to 30% during tillering stage. This showed that nitrogen ratesshould be controlled during the early stage of rice growth.
