Influence of Paddy Drying at Different Leaf Stages on the Stem-Tiller Dynamics and Yield of Rice
HUANG Chun-li
Abstract：For identifying the optimal paddy field drying time,a field trial was performed using the hybrid late-maturing rice variety Gangyou 827.The trial comprised a control (the paddy field was not treated by drying)and three treatments in which the paddy fields were dried at 10,11,and 12-leafstages.As a result,the highest rice yield of887.1kg/667m2 was attained in the field dried at 11 -leaf stage,followed by the fields dried at 10-and 12-leafstages with yields of831.5kg/667m2 and 804.8kg/667m2,respectively;the yields in these treatments all exceeded that of the control (753.7kg/667m2).The results indicate that the yield of rice can be signifi-cantly increased by drying the paddy field at effective tillering stage or slightly earlier;hence,this technique is worthy of promotion for rice cultivation.
