大量经验事实说明,气象条件对冬小麦产量有着不可忽视的影响。大面积的小麦产量是在自然环境中形成的,产量本身必然包含这种影响的某些信息。直接分析产量资料,从中提取有关信息,是研究上述影响的途径之一。过去曾有人对降水和小麦产量的关系作过一些分析。随着农业生产的飞跃发展,农业排灌条件的不断改善,栽培技术的
A large number of empirical facts show that meteorological conditions have a significant impact on winter wheat production. The production of large areas of wheat is formed in the natural environment, and the yield itself necessarily contains some information about this effect. Analyzing directly the yield data and extracting relevant information therefrom is one of the ways to study the above impact. There have been some analyzes of the relationship between precipitation and wheat production in the past. With the rapid development of agricultural production, agricultural irrigation and drainage conditions continue to improve, cultivation techniques
