宿县地区小麦面积占耕地面积60—70%,小麦产量占全区粮食总产35—50%,居举足轻重的地位.根据我区小麦的生态条件,对小麦品种的演变情况进行认真回顾,深化对当前生产应用品种特点的认识,充分发挥良种的增产作用,同时努力培育和应用新品种,是发展我区小麦生产一个值得重视的问题. 一、宿县地区小麦生态条件和小麦生态型淮北地区属于半湿润冬麦气候区.地处黄淮海平原的东南部,位于东经114°55′～118°10′,北纬32°25′～34°35′,为海拔15—16米之间的广阔平原,只有东北部有少数低山残丘.年平均温度14—15℃,1月平均温度为0.7—-1.3℃,最冷极端气温平均在-13℃左右,极端最低温度-24.3℃,这样的低温只是十几年
The area of wheat in Suxian area accounts for 60-70% of the total area of cultivated land, and the output of wheat accounts for 35-50% of the total grain output in the whole area, which holds a decisive position.According to the ecological conditions of wheat in our district, the evolution of wheat varieties is carefully reviewed and deepened The current understanding of the characteristics of production and application of varieties, give full play to the role of yield-increasing varieties, while efforts to cultivate and apply new varieties is the development of wheat production in our region is a problem worth noting. One, Suzhou County ecological conditions and wheat ecological Huaibei area It is located in the southeast of the Huang-Huai-Hai Plain, between 114 ° 55 ’to 118 ° 10’ east longitude and 32 ° 25 ’to 34 ° 35’ north latitude, with a vast area of 15-16 meters above sea level Plain, only a small number of northeastern residual hills. The average annual temperature of 14 - 15 ℃, January average temperature of 0.7--1.3 ℃, the coldest average temperature of about -13 ℃, the extreme minimum temperature of -24.3 ℃, so The temperature is only ten years
