为了筛选出适宜嘉峪关市中轻度盐碱地种植的食用向日葵新品种，以SH363为对照，对引进的8个食葵新品种进行了田间比较试验，对比分析不同品种的生育期、抗性、农艺性状、主要经济性状和产量。结果表明，三瑞11号生育期为102 d，属早熟品种，其余品种属中熟品种，在当地均能正常成熟。参试品种中，三瑞373、三瑞9号菌核病抗性好，且产量位居前2位，分别达5 257.26、5 191.67 kg/hm2，分别较对照品种SH363增产10.45%、9.11%(P ＜ 0.01)；三瑞10产量排第3，为5 005.56 kg/hm2，较对照品种SH363增产5.20%(P ＜ 0.05)。三瑞373和三瑞9号综合性状较好，建议在试验区示范种植。

Preliminary Report on Comparative Experiment of New Varieties of Edible Sunflower in Saline-alkali Land

In order to select new varieties of sunflower suitable for planting in medium and light saline-alkali land in Jiayuguan, using 8 new varieties of sunflower that were introduced and taking SH363 as the control, the comparative experiment was carried out by field test method. The growth period, resistance, agronomic and economic characters and yield of different varieties were compared and analyzed. The results showed that the growth period of Sanrui 11 was 102 d, which was considered as early maturing variety. The growth period of other varieties was considered as medium maturing variety and could mature normally in the local area. Sanrui 373 and Sanrui 9 had good resistance to Sclerotinia sclerotiorum, and their yields ranked as the top two.
