Effects of Different Water Supply on Water Demand and Yield of Rice

Shuqin Xu

Abstract

In order to research water requirement pattern、physiological characteristic and yield formation of rice,this text has taken different extent water deficit in each period of rice.The results shol,The different soil's moisture is extremely close to water demand and rice yield.The maximum influence of drought stage upon rice yield is the jointing-booting stage;the second influence stage is earing stage and the suitable water deficiency in tillering and filling stage can't bring tremendous effects on yield of rice.
