SIMULATION OF THRESHOLD OF DEEP IRRIGATION IN DIFFERENT GROWTH STAGES OF RICE

摘要：

To model the distance between the paddy surface and every pulvinus as growth days increasing, this research is based in deep per cent to total functional leaves to simulation of threshold of deep irrigation in different growth stage for rice, which would sustain the measure of paddy field saving water. The result showed that tested sum of squares about regression with 8 models,i.e.Y=a+bX,Y=a+log(X),Y=aex,Y=aXb,Y=1/(a-bX),Y=X/(a+bX),Y=a/(1+be(cx),Y=a+bX- cX2, there was excellent application for the equation Y=a+bX-cX2 which could be applicable to almost all the objects.Comparing the application, the second best was equation Y=X/(a+bX),the rest were not suitable for use.
