摘要
[目的]摸索庐江县庐城镇双季早稻主栽品种全程机械化最佳栽插密度。[方法 ]设置了3个栽培密度水平,比较不同栽培密度水稻茎蘖动态及产量构成。[结果]栽培密度越大茎蘖苗峰值越高。栽插密度25 cm×12 cm水稻产量最高,达8 358.0 kg/hm2。[结论]在高肥力田块双季早稻主栽品种全程机械化最佳栽插密度为25 cm×12 cm,而肥力水平较低的田块栽插密度以25 cm×10 cm为好。
[Objective]The aim of this study was to explore the best planting density of machinetransplanted double cropping early rice in Lucheng Town of Lujiang County.[Method]Three cultivation density levels were set to compare the tiller dynamics and yield composition of rice.[Result]The higher the density was,the higher the tiller peak value was.When planting density was 25 cm×12 cm,rice yield was the highest,reaching to 8 358.0 kg/hm^2.[Conclusion]The optimal planting density of double cropping early rice in highfertility field was 25 cm×12 cm,while the planting density of double cropping early rice in lowfertility field was 25 cm×10 cm.
