摘　　要：为了完善滨海稻区直播稻高产栽培技术体系,2017、2018年连续两年以不同品种为材料,采用随机区组试验,通过不同年份不同品种设置不同播期进行水稻湿润直播,测定其对直播稻生长发育及产量的影响,探索滨海稻区水稻湿润直播最佳播期。结果表明,播期为5月10日、5月12日处理A_(2)、B_(2)实际产量最高,分别为8.25、8.34 t/hm^(2),分别比机插秧减产14.86%、15.42%,但效益分别增加801、553元/hm^(2)。In order to improve the technique system of high-yield cultivation in coastal region,different varieties were used to determine the effects on the growth and yield of wet direct-seeding rice and explore the best sowing date in coastal region by setting different sowing date in 2017 and 2018 under random regional tests.The results showed that the actual yield of A_(2)and B_(2)were higher in May 10th and 12th,which were 8.25,8.34 t/ha,respectively.And these yield were 14.86%,15.42%lower than that of mechanized transplanting,but the benefits increased by 801 and 553 yuan/ha,respectively.
