棉花是喜温、喜光、需水量较大的作物。在棉花生育和产量形成过程中,光、温、水是不可替代的生态因子,棉花产量的高低及丰欠,在很大程度上取决于当地农业气候条件的适宜程度和变化情况。本文运用常规和近代的统计方法,通过对山东省重点产棉县——临清县产量变动的单点分析,寻找大面积生产水平和高产水平下,影响棉花产量变动的主导气象因子,及其影响的时间信息和程度,讨论各生育时段的供求矛盾。为趋利避害,提高农业气候相似
Cotton is a warmth, hi light, water needs larger crops. In the process of cotton growth and yield formation, light, temperature and water are irreplaceable ecological factors. The cotton yield and abundance depend largely on the suitability and changes of local agro-climatic conditions. In this paper, by using the conventional and modern statistical methods, through the single point analysis of the output changes of key cotton producing counties-Linqing County in Shandong Province, we find the dominant meteorological factors that affect the cotton yield changes under large-scale production and high-yielding levels, The impact of time information and degree, to discuss the contradiction between supply and demand of each growth period. For the sake of avoiding disadvantages and improving the agricultural climate,
