The study shows that heat,water and light coordinated closely in the abundant years;on the contrary,the comprehensive meteorological conditions were unfavorable for agricultural production in the lean years. A good yield showed up when there were a higher temperature and a larger amount of accumulated temperature above 10 ℃ with no sign of cold damage,an exactly favorable precipitation distribution with little drought or water-logging and a comparatively abundant light during the growing season(from May to September) . However,the crop yield was low when there were a lower temperature and a smaller amount of accumulated temperature,an abnormal precipitation distribution with drought or water logging and scant sunlight during the growing season(from May to September).展开更多
