上海地区三麦产量高而不稳,其原因是多方面的。我们从农业气象角度,着重研究了三麦产量丰歉与气候条件之间的定量关系,并据此建立作物产量的预报模式。现将三麦产量预报及分析方法作一简述,供参考。 (一)预报模式作物产量的形成是一个非常复杂的过 Three high-yield wheat in Shanghai and instability, its many reasons. From the perspective of agricultural meteorology, we focus on the quantitative relationship between the apricot yield and climatic conditions and establish a forecast model of crop yield. Now three wheat production forecasting and analysis methods for a brief, for reference. (A) forecast model The formation of crop yield is a very complicated
