利用积温预报早籼、早中籼稻生育期模式的研究
STUDY ON A NEW MODEL FOR THE FORECAST OF HEADING DATE OF EARLY AND MEDIUM EARLY INDICA RICE BY ACCUMULATED TEMPERATURE
【摘要】 根据各温度级有效积温(>10℃)与生育期的相关系数可以把10℃至33℃之间的日平均温度的作用效应分成不等的五段,就五段温度对生育期影响的不同作用值进行模拟,并用以进行抽穗期预报。
【Abstract】 On the basis of the correlation cofficient between the accumulated temperature(>10℃)of the different temperature scales and the growth duration from sowing to.heading,the effective function of the average daily temperature from 10℃ to 33℃ could be divided into 5 sections.Computer simulation was conducted for the different functional values of the effect of the temperature of the 5 sections on the growth duration and a new model for forecasting the da.te,of heading in rice was suggested.
