摘要
通过温热因子和小麦产量的相关分析及最优回归模型的建立,结果表明在降水较少的地区,温热增产作用未能正常发挥;在降水较多的地区,温热增产作用则得到一定程度的发挥;并针对不同地区分别提出了相应的小麦增产措施。
Through correlation analysis of temperature, heat and wheat yield in Shaanxi province, an optimum regression model of them is established. It's indicated that in less precipitation areas of this province, the yield-increasing effect of temperature and heat is not normally brought into play, but in more precipitation areas, this effect brings into paly to a certain extent. Corresponding yield-increasing measures for wheat in various areas of this province are put forward in this paper.
