[目的]研究不同播期和移栽密度对皖稻68生育期,产量及其构成因素的影响.[方法]设播期和移栽密度2个因素.其中,播期设5个水平(5月5、15、25日,6月4、14日),移栽密度设3个水平(22.20万、27.75万、33.30万穴/hm2),共15个处理.[结果] 播期越早全生育期越长,播期越迟全生育期越短;相同播期不同移栽密度生育期及全生育期天数基本一致.皖稻68的产量以播期5月15日,移栽密度27.75万、33.30万穴/hm2时最高.播期和移栽密度对皖稻68产量构成因素影响较大.[结论]为皖稻68的在安徽的大面积推广种植提供了科学依据.

[Objective] The research aimed to study the effects of sowing time and transplanting density on the growth period, yield and component factors o Wandao 68.[Method] Sowing time(05-05, 05-15, 05-25, 06-04, 06-14) and transplanting density(22.20×104, 27.75×104, 33.30×104 plants per hectare) were chose as factors to do the experiment.[Result] The earlier the sowing time, the longer the whole growth period.The every growth period and the whole growth period under same sowing time and different transplanting density were basically identical.The yield of Wandao 68 was the highest when the sowing time was 05-15 and the transplanting density was 27.75×104, 33.30×104 plants per hectare.Sowing time and transplanting density had great influence on the yield component factors of Wamdao 68.[Conclusion] The study can provide scientific basis for planting Wnadao 68 in large scale in Anhui Province.
