采用正交多项式和积分回归方法,利用大豆产量与光、温、水三要素的相关性,以及能够反映大豆各生育时段、各气象要素对产量影响程度的偏回归系数,从光、温、水三方面对东平县夏大豆作气候条件分析,为决策服务、产量预报等提供依据
Orthogonal polynomial and integral regression were used to study the correlation between soybean yield and light, temperature and water, as well as the partial regression coefficient that can reflect the effect of each meteorological factor on the yield during each growth period of soybean. Three aspects of Dongping County summer soybean for climatic conditions for decision-making services, production forecast provide the basis
