阿勒泰地区食用型向日葵品种筛选试验

Screening Test of Confectionery Sunflower Varieties in Altay Prefecture

针对阿勒泰地区富蕴县引进种植的7个食用型向日葵品种的全生育期、农艺性状和产量等进行比对分析,结果表明:新食葵7号折合单产3 815.55 kg/hm2,该品种籽粒大小适中;新食葵7号和RH318植株高度适中,结实率高,比较适宜在阿勒泰地区种植,如能加强花期水肥管理,进行防蜂辅助授粉,单产应在3 750 kg/hm2以上。

A comparison analysis was made on the total growth periods, agronomic characters and yields of 7 confectionery sunflower varieties introduced in Fuyun County in Altay Prefecture. The results showed that the yield of Xinshikui No.7 was3 815.55 kg/hm2 and the variety’s seed size was moderate and the plant heights of Xinshikui No.7 and RH318 were moderate and their seed setting rates were high and they are suitable for growing in Altay Prefecture. If the water and fertilizer management during the flowering period could be strengthened and the anti bee pollination could be carried out, their yields should be over 3 750 kg/hm2.
