摘　　要：通过分期播种试验,确定了河套灌区主要经济作物向日葵适宜播种时期,并根据对应气候资料,采用相关分析和回归分析方法,确定了向日葵适宜播种农业气象指标。结果表明,食用和油用两类向日葵品种播种越早,出苗期和生育期越长,积温也越高。食用向日葵适宜播种农业气象指标为气温稳定通过5℃初日,其适宜播种范围在4月6日—4月30日,油用向日葵适宜播种农业气象指标为气温稳定通过10℃初日,其适宜播期范围在4月19日—5月16日。Adopting correlation analysis and quantitative analysis method with corresponding meteorological data, the optimal sowing dates and relevant index of meteorological conditions for edible and oilseed sunflower cultivars were identified through experiment of sowing by stages. The optimal sowing dates for edible cultivar of sunflower was between April 6th and April 30th. The optimal sowing dates for oilseed eultivar of sunflower was between April 19th and May 16th. The first day was regarded the primary forecasting index of sowing date when the air temperature was steadily above 5 ℃for edible sunflower planting. The first day was regarded the primary forecasting index of sowing date when the air temperature was steadily above 10 ℃ for oilseed sunflower planting in this areas.
