摘要
应用1996—2006年水稻生长发育资料和同期的地面气象观测资料，借助一元非线性回归统计方法，建立了水稻播种至三叶期、移栽至分蘖期、分蘖至抽穗期的生长速度、有效分蘖及孕穗至抽穗所需日数与日平均气温关系的数学模型。并根据模型对水稻有关发育期生长所需的空气温度作了定量的分析。
According to the datum of rice agrometeorological and surface meteorological observation of 1996 - 2006, the mathematical models of one - variable nonlinear regression about effect of air temperature on growth of rice from sowing to third leaf seedling stage, transplanting stage to tillering stage, tiUering stage to heading stage, number of effective tillers and the days of spike formation to heading stage were established. The air temperature for rice growth was quantitatively analyzed based on the models.
