东辛农场是北方甜菜种子南繁的重要基地。抗寒保苗是本场如何进一步发展采种甜菜的关键之一。为此,我们通过三年露地越冬采种甜菜冻害的试验研究,初步探讨了甜菜要具有较强的抗寒性,冬前必须达到一定的苗龄、根径及适宜的叶色指标。以这些指标为依据,进而初步确定了较适的播期、施肥技术、深栽培土可作为采种甜菜安全越冬 East Xin farm is an important base of the North beet seed South Fan. Cold seedling is how to further develop this field is one of the keys to planting sugar beet. To this end, we have adopted three years of wintering winter planting sugar beet frost damage experiments to explore the beet to have a strong cold resistance, before winter must reach a certain age, root diameter and suitable leaf color indicators. Based on these indicators, and then determine the appropriate sowing date, fertilization techniques, deep planting soil can be used as a safe planting sugar beet
