在影响棉花产量的多变量综合因素中,气候因素与棉花产量关系的定量化、模式化研究,是揭示棉花产量年际间变化原因及产量动态趋势的主要手段。它所提供的棉花产量形成的气候信息也是棉花生产趋利避害,改进栽培技术,产量预测以及制定棉花生产发展战略决策的参考依据。为此,本文选择安徽淮北阜阳地区的代表县对棉花气候生产力及产量模式进行了研究。
Among the multivariable factors influencing cotton yield, the quantitative and schemata studies on the relationship between climatic factors and cotton yield are the main means to reveal the interannual variation of cotton yield and the dynamic trend of yield. The climatic information provided by the cotton production is also the reference basis for making profits and avoiding disadvantages of cotton production, improving cultivation techniques, yield forecasting and making strategic decisions on the development of cotton production. Therefore, this paper selects the representative counties in Fuyang, Huaibei, Anhui, to study the cotton climatic productivity and yield patterns.
