Abstract: In this study,rice was subjected to 16% and 21% of soil water content from 15 DBH(days be-fore harvest)to 13 DAH(days after harvest).The results show that:(1)the dormant buds were more sensitive to soil water content at 15 DBH than at 13 DAH. Rice yield of ratcon crop de-creased with decreasing soil water content;(2)survival rate of dormant buds and regenerated tillers and rice yield decreased with decreasing soil water content and days of water treatment;(3)yield reduction of main crop was caused by lower ripen grains and 1000-grain wt.;However,depression in grain yield of ratoon crop may be attributed to insufficient panicles in rice ratconing;(4)survival rate of dormant bud, regenerated tillers and yield of ratoon crop decreased sharply when the soil water content was lower than 21%,which may be regarded as critlcal soil water content to judge the effects of drought on rice ratooning from 15 DNH to l3 DAH.
Key words: environmental sustainability, urban sustainable development, decision-making and trial evaluation , laboratory (DEMATEL) method.
