Abstract
The effect of different moisture management modes on root growth and rice grain yield under no tillage was studied.The results showed that dry-wet alternate irrigation had an obvious influence on rice grain yield,rice root growth,root length and physiology.The rice shoot dry weight and biomass per plant,root radius,root area,root number,root activity and supperoxide dismutase(SOD) activity under dry-wet alternate irrigation were significantly higher than those under flooded irrigation.Dry-wet alternate irrigation significantly increased rice grain yield,which resulted from increased effective panicle number,spikelet number per panicle and seed setting rate,compared with flooded irrigation.The biomass per plant,root radins,root area,root number and SOD activity under dry-wet alternate irrigation were significantly higher than those under wetting irrigation.There were no significant difference in rice grain yield between the two treatments.
