摘要
本文提出了生育期模糊集的概念,并根据假设、三分法原理和经验,建立了各生育期的隶属度函数,从而进行水稻生育期的模糊识别。同时还根据实验数据,确定参数与光、温等气象因素的统计关系。
The rice growth speeds is indicated by rice growth duration.For the bounds between adjacent growth stages are indistinct,the fuzzy set concept of rice growth stages was described in the paper.And further,according to some accumptions,mathematical principle and experience,the membership function of every growth stage is constructed.Moreover,on the basis of experimental data,the statistical relations between parameters and temperature,seeding date etc.are developed.
