用正交多项式模型Fisher提出的单、偏相关假设检验及逐步回归等统计学方法,定量地探讨富顺逐年早、中稻产量与光、热、水的基本关系和规律。表明富顺早、中稻产量波动的主要气候原因,是六月极端最高气温和六月上旬的平均气温、其丰、欠产量的预报可利用下列回归方程。 Y=371.48-1.668T_(Max)6月-9.002T上/6月本研究旨在为了解水稻气候生态、发挥川东南水稻优势作参考、讨论。
Using the statistical method of single and partial correlation hypothesis testing and stepwise regression proposed by orthogonal polynomial model Fisher to quantitatively explore the basic relations and regularities of yield, light, heat and water of Fushun year by year. The main climatic reasons for the Fushun and mid-season rice output fluctuations are the extreme maximum temperature in June and the average temperature in early June. The following regression equations can be used for forecasting abundance and under-production. Y = 371.48-1.668T_ (Max) June -9.002T on / June The purpose of this study is to understand the climatic ecology of rice and give full play to the advantages of paddy in southeastern Sichuan as a reference and discussion.
