忻州地区高寒山区由于气温低,无霜期短(110—120天),习惯种植小日期作物。为了政变高寒山区的低产面貌,以地区科协带头,在高寒山区开发高产作物,取得了明显效果。1988年,种植高产作物玉米、高梁、马铃薯10.7万亩,平均亩产283.6公斤,比前4年平均产增加47.5％。 1.应用地膜覆盖技术开发玉米。海拔1300米以上的高寒区,过去不能种植玉米,采用地膜覆
Xinzhou cold mountainous areas due to low temperatures, frost-free period is short (110-120 days), the habit of planting small-time crops. In order to change the low-yielding appearance of the alpine mountainous areas, the CASTU took the lead in developing high-yield crops in the alpine mountainous areas and achieved remarkable results. In 1988, 107,000 mu of high yield crop corn, sorghum and potato were planted, with an average yield of 283.6 kilograms, an increase of 47.5% over the previous 4 years. 1. Application of plastic mulching technology to develop corn. Alpine region above 1300 meters above sea level, the past can not be planted with corn, the use of plastic cover
