Abstract

Rice physiological characteristics and population development under SRI (system of rice intensification) condition were studied by using japonica cultivar Wuxiangjing 9. Results showed that SRI significantly enhanced root activity, increased soluble sugar, non protein nitrogen, proline and malondialdehyde (MDA) contents in leaf, dry matter translocation percentage from vegetative organs to grains, and improved population quality remarkably. Rice yield, however, was limited by lower tiller number and panicle number of plant population. Under SRI condition, planting two seedlings per hill could increase tiller number of plant population, dry matter translocation percentage from vegetative organs to grains and improve population quality, which was in favor of yield increase. With increasing nitrogen rate,tiller number of plant population increased,whereas dry matter translocation percentage from vegetative organs to grains decreased, suggesting yield increase under SRI should not rely on the excess nitrogen rate.
