Abstract
The relationship between population quality after heading stage and yield formation under SRI cultivation pattern was studied systematically using the high yield rice Liangyoupeijiu and IIyou7954 as material.The results showed that SRI cultivation had no advantage over the conventional cultivation in the ears number per hm(2),however,SRI could improve population quality after heading stage and formed big spikelet.Adopting the proper plant density under SRI condition,there ase good gesture from inverse 1~(st) leaf to 3~(rd) leaf at heading stage and leaf area decrease rate was low from heading stage to 20 days after flowering.SRI had obviously advantage over the conventional cultivation in photosynthesis and the accumulation matter with the higher weight of the stem and sheath,availing to increase grains per panicle and seed setting rate,and to form big spikelet.
