我省忻州地区北部、朔州市、大同市是春小麦的主要产区,由于生态条件和小麦本身生长发育规律,具有“一早二短”的生育特点,即:穗分化起步早,穗分化时间短,生育期短。春小麦在春季三叶期已开始穗分化,由于气候影响,穗分化过程仅30多天,生育期95～110天.针对以上特点,从“早”字出发,早备耕、早播种、早管理、即可达到高产优质高效,如天镇县东沙河村600亩小麦,亩产350公斤,张存林3.6亩春小麦,平均亩产405公斤,李密2亩晋春9号,亩产达456公斤。
The main producing areas of spring wheat in the northern part of Xinzhou, Shuozhou and Datong in our province are the reproductive characteristics of “one morning and two short” due to the ecological conditions and the growth and development of wheat itself, ie, the ear differentiation is started early and the ear differentiation time is short , Short growth period. Due to the influence of climate, the process of spike differentiation is only more than 30 days and the growth period is 95 ~ 110 days.According to the above characteristics, starting from “Zao”, spring wheat is ready for early planting, early sowing and early management, To achieve high yield high quality and efficiency, such as Tianzhenhe County Tianzhen 600 acres of wheat, 350 kg per mu, Zhang Cunlin 3.6 acres of spring wheat, an average of 405 kg per mu, Li Mi 2 acres of Jinchun 9, 456 kg per mu.
