Screening of Suitable Sowing Date for Yumi 2 in Arid Area of Western Heilongjiang Province

In order to determine the best sowing date of the main cultivar Yumi 2 in Shaanxi Province, taking Yumi 2 as experimental materials, five sowing periods were set: May 8 (B1), May 18 (B2), May 28 (B3), June 7 (B4), and June 17 (B5), and field experiment was carried out in Heping Pasture of Suihua Administration Bureau in Heilongjiang Province. The plant height, main panicle length, main stem node number, grain number per panicle, 1000-grain weight, and yield of Yumi 2 were compared under different treatments. The results showed that the treatments of B1, B2 and B3 were higher than those of B4 and B5 in the plant height, main panicle length, main stem node number, grain number per panicle and 1000-grain weight. The yield of B1 was the highest in five treatments, and the yield was higher than that of B2, B3, B4 and B5 for 7.41%, 8.33%, 28.70%, and 19.44% respectively. Based on the above traits, it is concluded that the appropriate sowing date of Yumi 2 is May 8 in the arid area of western Heilongjiang Province so as to get higher yield.
