在我国向日葵是一种经济价值很高的新兴油料作物,大面积生产近年来发展很快,吉林省白城地区目前每年播种面积在200万亩以上。为了给向日葵生产的发展提供一定的气象、气候科学依据,白城地区农业气象试验站从1982年起开始了“向日葵栽培生态与气象”的研究.探索向日葵一生各阶段的生育动态及产量形成与气象条件的关系以及生育关键时期气象指标的鉴定,为制定向日葵栽培措施、产量予报和向日葵农业气候区划提供依据。为此我们对1978至1982年的吉林省向日葵杂交种区域试验的气象资料,和1982年至1984年进行的分期播种试验的气象资料,进行分析整理。
Sunflower in our country is a kind of emerging oilseed crop with high economic value. Large-scale production has developed rapidly in recent years. At present, the annual planting area of Baicheng in Jilin Province is more than 2 million mu. In order to provide a certain meteorological and climatic scientific basis for the development of sunflower production, Baicheng Regional Meteorological Experiment Station started to study the “sunflower cultivation of ecology and meteorology” from 1982. To explore the growth and development of sunflower in all stages of life and the formation of meteorology Conditions and the identification of meteorological indicators during the critical period of fertility provide the basis for the formulation of sunflower cultivation measures, yield and sunflowers and agricultural climate zoning. To this end, we analyzed the meteorological data of the regional trials of sunflower hybrids in Jilin Province from 1978 to 1982 and the meteorological data of the sowing trials conducted in phases from 1982 to 1984.
