摘　　要：为了探求优质稻华浙优261的种植模式,2023年在浙江省金华市汤溪镇寺平村开展连作晚稻华浙优261施肥量及其不同栽插密度的栽培试验。试验设置4个肥料梯度,即0(F0)、120(F1)、165(F2)、210 kg/hm^(2)(F3);3个栽插密度处理,即19.5(M1)、22.5(M2)、25.5万穴/hm^(2)(M3),共计12个处理。结果表明:随着施肥量的增加,华浙优261最高苗数、有效穗数、株高、干物质重和产量均增加;在一定肥料水平下,随着移栽密度增加,最高苗数、有效穗数增加,但产量及其他性状在处理间差异不大;12个处理间以F3M2的产量最高,达8.60 t/hm^(2)。In order to explore the cultivation pattern of the good quality rice variety Huazheyou 261,a cultivation experiment on the fertilization amount and different transplanting densities of late rice Huazheyou 261 was carried out in Shiping Village,Tangxi Town,Jinhua City,Zhejiang Province in 2023.The experiment set up 4 fertilizer gradients,namely 0(F0),120 kg/hm^(2)(F1),165 kg/hm^(2)(F2),and 210 kg/hm^(2)(F3),and 3 density treatments,namely 195,000 holes/hm^(2)(M1),225,000 holes/hm^(2)(M2),and 255,000 holes/hm^(2)(M3),totaling 12 treatments.The results showed that with the increase of nitrogen application rate,the maximum tiller number,effective panicle number,plant height,dry matter weight,and yield of Huazheyou 261 all increased.At a certain fertilizer level,with the increase of transplanting density,the maximum tiller number and effective panicle number increased,but there were no significant differences in yield and other traits among the treatments.Among the 12 treatments,the yield of F3M2 was the highest,reaching 8.60 t/hm^(2).
