本文通过在自然状态下的大面积田间试验与平行气象观测相结合的方法,研究了松嫩平原北部地区的气象条件(包括太阳辐射、气温、降水)与当地主栽作物玉米、大豆、小麦、甜菜的生长发育及群体生产力之间的关系,并得出结论:1.当地光能资源潜力较大,热量条件是主要限制因子,自然降水量是影响因子。2.玉米对当地光、热、水资源的综合利用程度最高,大豆和甜菜次之,小麦略差。3.但就气候生态适应性而言,以大豆表现最佳,甜菜次之,小麦和玉米略差。
In this paper, the combination of meteorological conditions (including solar radiation, air temperature and precipitation) in the northern Songnen Plain with those of the main crop maize, soybean, wheat, Beet growth and development and population productivity, and concluded: 1. The potential of local light energy resources, heat conditions are the main limiting factor, the natural precipitation is the impact factor. 2. Corn on the local light, heat, water and comprehensive utilization of the highest degree of second soybean and beet, wheat slightly worse. 3. In terms of climatic and ecological adaptability, however, soybeans perform the best, followed by beets, with slightly worse wheat and corn.
