摘要
本文以辽宁省台安县26年水稻产量为例,采用正交多项式、积分回归方法,分析了水稻产量与温度、降水、日照的利弊关系,组建了水稻产量预测模式,并指出了提高水稻单位面积产量的途径。
The rice yield data of 26 years in Taian County were analysed to reveal the advantageous and disadvantageous relationship between the yield and the factors of temperature, precipitation and sunlight. A model of rice yield forecasting wils established and the way to elevate rice yield per unit area was suggested.
