我们榆次县夏播小麦研究,经过6年的试验示范,在海拔1,000米以上的丘陵山区种植,普遍比当地冬小麦产量高而稳,为这类地区开拓了一条小麦生产的新途径,对发展农业生产具有深远的意义。一是在比重很大的丘陵山区,解决了小麦产量不高不稳的问题。冬小麦在这类地区由于缺水干旱造成越冬受冻死苗,春季返青不好,夏季干热风秕粒。这三个不可克服的自然因素,造成这类地区小麦产量不高不稳,三十年来我县小麦平均亩产仅129斤,主要 After six years of experiment and demonstration, we planted summer sowing wheat in Yuci County and planted it at a hilly mountain area above 1,000 meters above sea level, which is generally higher and more stable than that of the local winter wheat. This has opened up a new way for wheat production in such areas. Agricultural production has far-reaching significance. First, in a large proportion of hilly areas, to solve the problem of not high and unstable wheat yield. Winter wheat in such areas due to lack of water and cold winter frigid dead seedlings, spring back green is not good, summer dry hot wind pellets. These three insurmountable natural factors have caused the unstable output of wheat in these areas. In the past 30 years, the average yield per mu of wheat in our county has reached only 129 pounds,
