我区地处塞外,海拔550—740米,年平均气温7—8℃,无霜期135天左右,年降雨量300毫米左右。全年风多雨少,秋季凉爽短促,日温差较大。由于气候因素的影响,历史上大白菜种植少、产量低,一般亩产四、五千斤,远远不能满足人民生活的需要。为了改变这种局面,我们从1974年开始,进行了十一年塞外大白菜高产稳产技术的探索,并积累了一些经验。
My area is located outside the plug, elevation 550-740 meters, the annual average temperature of 7-8 ℃, frost-free period of 135 days or so, the annual rainfall of about 300 mm. Year less rainy, cool and short autumn, daily temperature difference. Due to the influence of climatic factors, the history of cabbage cultivation is low, the yield is low, generally yielding four or five kilograms, far from meeting the needs of people’s lives. In order to change this situation, we started from 1974, carried out 11 years of extra-high yield and stability of cabbage exploration technology, and accumulated some experience.
