以湖南桃源为试验观测点,对江汉—洞庭平原早稻和晚稻的主要当家品种与栽培环境中最重要的因子,即气象条件的关系作了多年的观测研究。结果表明,气象因素中的温度、光照和降雨等因素对水稻的生长发育影响最大。並通过影响水稻生育期、株高、分蘖动态、出叶速度、叶面积系数,幼穗分化,干物质积累而最终影响产量的高低。 Taking Taoyuan of Hunan Province as the experimental observation point, many years of observational studies have been made on the relationship between the main dominant species of early and late rice in Jianghan-Dongting Plain and the most important factor in the cultivation environment, namely the meteorological conditions. The results showed that the factors of temperature, light and rainfall in the meteorological factors had the greatest impact on the growth and development of rice. And ultimately affected the yield by influencing the rice growth period, plant height, tillering dynamics, leaf speed, leaf area coefficient, spike differentiation and dry matter accumulation.
