摘　　要：研究3种移栽密度对水稻新品种乌兰1号产量的影响,结果表明:30 cm×17 cm的移栽密度产量居首位,平均产量威9799.5 kg/hm^(2);30 cm×16 cm的移栽密度产量为第二位,平均产量9502.5 kg/hm^(2);30 cm×18 cm的移栽密度平均产量9199.5 kg/hm^(2),居第三位。处理1平均产量高,源于单位面积有效分蘖率高、有效穗数增多、平均实粒数多、结实率高。The effect of three transplanting densities on the yield of new rice variety Wulan-1 was studied.The results showed that the yield of 30 cm×17 cm transplanting density was the first,and the average yield was 9799.5 kg/hm^(2).The yield of 30 cm×16 cm transplanting density was the second,with an average yield of 9502.5 kg/hm^(2).The average yield of 30cm×18cm was 9199.5kg/hm^(2),ranking the third place.In treatment 1,higher average yield was due to higher effective tiller rate per unit area,more effective panicle number,more average solid grain number and higher seed setting rate.
