鉴于我省气候条件差异较大,小麦生产上存在苗期积温不足,缺水干旱,越冬死苗等制约因子。因此,以采用发挥综合效益的冬覆盖为宜。覆盖重点应放在低产晚播麦田和高寒山区越冬死苗的麦田。 1.选择土地不论覆盖水地还是旱地,一定要选择地形平坦,土层深厚,土质较绵,肥力较好的中等地力水平的耕地。高寒山区要求在调查作物布局基础上,做到麦田 In view of the large differences in climatic conditions in our province, the wheat production has restrictive factors such as lack of accumulated temperature at the seedling stage, drought and water shortage, and winter overwintering. Therefore, it is advisable to adopt a winter coverage that has a comprehensive benefit. Coverage should focus on low-yielding late-sowing wheat fields and alpine mountain winter dead seedlings of wheat fields. 1. Choice of land Regardless of covering the water or dry land, be sure to choose a flat terrain, deep soil, cotton soil more fertile, moderate fertility level of arable land. Alpine mountains require investigation of the crop layout, based on wheat fields
