水稻产量高低 ,直接受制于源库建立及相互关系的影响 ,实践中建立适宜的密度和合理的群体有利于改善水稻的生长特性 ,在空间上创造良好的产量结构。本研究旨在通过杂交粳稻稀植化群体质量栽培途径调控群体质量 ,既有利于发挥大穗“强库”的优势 ,又有利于提高植株抽穗前的干物
The level of rice yield is directly controlled by the establishment of source stocks and its relationship with each other. Establishing proper density and reasonable population in practice is beneficial to improving the growth characteristics of rice and creating a good yield structure in space. The purpose of this study is to control the population quality through the quality cultivation of hybridized Japonica seedlings. It is not only beneficial to play the advantages of big spike “strong base”, but also to improve the dry matter before heading
