在本田生产条件下，选用辽宁省选育的10个水稻品种为材料，研究4个不同播期、移栽期对水稻产量和品质的影响。结果表明，随着播期和移栽期的延后，不同品种产量呈下降趋势；随着移栽期的延后，各个品种的蛋白质含量显著提高。

Using 10 japonica rice varieties of Liaoning Province as materials, an experiment of sowing and transplanting by four stages was conducted in 2014 and 2015. The influences of 4 different sowing and transplanting stages on rice yield and quality were studied. The results showed that the grain yield decreased and the protein content increased significantly with the delay of sowing date and transplanting date.
