[Objective]To study the suitability of two spring wheat planted in Shapotou Area. [Method]Taking Ningchun 4 as tested wheat varieties, sowing in July 17th and July 13th, 2015, effect of different sowing stage on the growth period, seedling growth, yield and economic characters were studied. Compared with the parameters in the past year, the suitability of two spring wheat was evaluated. [Result]Total growth period of Ningchun 4 was 73 to 77 d, the basic seedling number was more than 2 million plant/hm2, 1 000 grain weight was 22.10~23.15 g, theoretical yield was 2 625~2 730 kg/hm2, but most of the indexes was reduced over the years. [Conclusion]Combined with economic cost and field management, it was concluded that two crops of wheat were not suitable for popularizing in Shapotou Area.关键词
