摘　　要：研究了播期和栽培密度对晚稻品种鄂粳403产量构成因素的影响。结果表明,鄂粳403在湖北省作双季晚稻种植最适播期为6月18-25日,中上等肥力水平下的适宜栽培密度为37.5万~45.0万穴/hm^2。The effects of sowing date and planting density on the yield characters of late japonica rice variety E-Jing 403 were studied.The results showed that the reasonable sowing date of E-Jing 403 in Hubei province was between June 18 and June 25.And the reasonable planting density was between 37.5×104 hill/hm^2 and 45.0×104 hill/hm^2.
