小麦是社旗县的主要种植作物,其产量受诸多因素制约,一方面受品种、土壤肥力和农业技术措施等基本农业生产条件影响;另外,气象条件作为一个重要因子,尤其是小麦生育期间温度、日照、降水等因素,影响着小麦的最终产量。本文用数理统计学和模糊数学方法分析降水变化对社旗县冬小麦的影响,建立相关数据库,在Excel软件的支持下,利用二阶多项式将农作物产量和气象因子分离成社会量和物理量进行研究。并根据降水量变化,对全县小麦产量的大小,进行了利弊分析。对提高农业生产能力、适应气候变化等都有很大的指导作用。
Wheat is the main planting crop in Sheqi County. Its yield is restricted by many factors, which are influenced by basic agricultural production conditions such as variety, soil fertility and agricultural technical measures. In addition, meteorological conditions are an important factor, especially during the growth of wheat , Sunshine, precipitation and other factors, affecting the final output of wheat. In this paper, we analyzed the effect of precipitation on winter wheat in Sheqi county by means of mathematical statistics and fuzzy mathematics, and established the related database. With the support of Excel software, we used the second order polynomial to separate crop yield and meteorological factor into social quantity and physical quantity. According to the change of precipitation, the pros and cons of wheat production in this county were analyzed. It has a great guiding role in improving agricultural production capacity and adapting to climate change.
