农作物的产量是土壤、气候、生物等生态因素和生产条件、栽培措施等人为因素综合影响的结果。这些影响作物产量的诸因素之间是相互联系、相互依赖而又相互制约的。任何一项因素的变化都会引起其它因素不同程度的变化,从商对农作物的产量产生直接或间接的影响。当现今农业生产还处于人为因素无力控制或改变气候条件的情况下,无疑气候因素对农业生产起着直接的重要作用。即便将来科学技术水平达到相当现代化的程度,也只能局部地对某一项或某几项气候因子在趋利避害或化害为利方面有所收效,但终难完全摆脱气候对农业生产的直接影响。 Crop yields are the result of the combined effects of human factors such as soil, climate, biological and other ecological factors and production conditions and cultivation measures. The factors that affect crop yields are interdependent, interdependent and mutually restrictive. Changes in any one factor will cause other factors varying degrees of change, from the business of the crop yield directly or indirectly. When agricultural production is still under the inability to control or change climatic conditions by human factors, it is no doubt that climatic factors play an important and direct role in agricultural production. Even if the level of science and technology reaches a fairly modern level in the future, it will only be able to locally benefit certain areas or certain climatic factors in their profit-taking or harm-taking. However, it will eventually get rid of the climate’s impact on agricultural production The direct impact.
