Abstract
With the hybrid rice Gangyou 527 as the material,physiological indices,grain filling features and grain yield were studied among different cultivation methods,including planting method of triangle of system of rice intensification(TSRI),system of rice intensification(SRI),broadcasting rice seedling and traditional cultivation.The results showed that TSRI with suitable planting density had the unique superiority in population quality with bigger leaf area index in the key growth stages,delayed aging of flag leaf after heading,and higher photosynthetic rate.TSRI could also give full play to the growth of every individual plant and more photosynthetic assimilates were produced,accumulated and transported into panicles,which not only ensured the grain filling of superior grains but also improved greatly the grain filling of inferior grains on a panicle.Consequently, a higher grain yield was achieved through the optimization of structure of yield components.
