为了研究单本密植机插和常规机插对杂交稻分蘖动态、干物质积累、辐射利用率和产量及产量构成的影响,在湖南省浏阳市以杂交稻泰优390、五优308为材料和在广东省肇庆市以五优308为材料,进行印刷播种和常规播种的秧苗素质比较以及单本密植机插和常规机插的大田栽培试验。结果表明,两试验点印刷播种的叶龄、白根数、总根数、茎基宽、地上部干重和地下部干重均明显高于常规播种。单本密植机插的最高分蘖数和有效分蘖数显著低于常规机插,但单本密植机插的每穗粒数、总颖花数、结实率和千粒重高于常规机插,增产10.28%~13.96%,达到显著水平。从穗部性状来看,单本密植机插的一次枝梗数、二次枝梗数、穗长...

The high sowing rate and poor transplanting performance hinder a large-scale mechanized transplanting of hybrid rice in China. In order to study the effects of mechanized transplanting with high hill density and single seedling per hill (MTHS) and conventional mechanized transplanting (CMT) on tillering, dry matter accumulation, radiation use efficiency, grain yield and its components, comparisons of seedling quality between printing sowing and conventional sowing, and field experiments between MTHS and CMT were conducted using hybrid rice cultivars Taiyou 390 and Wuyou 308 at Liuyang, Hunan p...
