作物产量的高低,在农业技术措施相对稳定的情况下,主要决定于当地的气候条件。因此,摸清作物生长发育与气候条件之间的关系,乃是充分利用有利的气候资源,预防和避免气象灾害,争取农业稳产高产的重要手段。本文通过对荷泽地区大豆产量的气候条件分析,初步找出影响大豆产量的气候条件的利弊所在,为大豆的稳产高产提供理论上的依据。一、大豆产量与降水量的关系:根据大豆生长的特性和菏泽的气候条件来分析,大豆产量与八月的降水量呈显著的正相关,与六月的降水量有一定程度的正相关,而与七月份的降水量则有一定程度的负相关(各月相关系数见下表)。即大豆的产量随六、八月(特别是八月)的降水量的增加而增加,随七月份降水量的增加而减少。
The level of crop yield, with relatively stable agricultural technological measures, depends mainly on the local climatic conditions. Therefore, finding out the relationship between crop growth and development and climatic conditions is an important means to make full use of favorable climatic resources, prevent and avoid meteorological disasters and strive for stable and high-yield agriculture. Based on the analysis of climatic conditions in Heze region, this paper initially identifies the pros and cons of climatic conditions affecting soybean yield and provides a theoretical basis for the stable and high yield of soybean. First, the relationship between soybean yield and precipitation: According to the characteristics of soybean growth and climate conditions in Heze to analyze, soybean yield and precipitation in August was a significant positive correlation with precipitation in June have a certain degree of positive correlation, While there is a certain degree of negative correlation with precipitation in July (the correlation coefficient of each month is shown in the following table). That is, the yield of soybean increased with the increase of precipitation in June and August (especially in August), and decreased with the increase of precipitation in July.
