摘要
甜菜在出苗期及出苗后（包括子叶期）能耐－5℃的低温，适时提早播种，甜菜前期叶面积增大15．6％－26．6％，可提高块根产量10．8％－16．0％。
Sugar beet at seedling stage and post -seedling stage (including the cotyledon stage) could resist low temperature at-5℃. Early sowing could incarese the leaf area at prophase of sugar beet growth by 15.6% ~ 26.6%, and finaly could increase its root tuber yield by 10.8% ~ 16.0%.
