摘要
为贺州市冬季马铃薯合理安排播种期、科学调整面积布局,避免或减轻低温冻害影响提供气候依据,通过近年冬种马铃薯灾害天气调查,结合贺州市各县区低温冻害出现时段及低温程度等方面的气候分析。结果表明:冬季低温冻害是影响贺州市冬种马铃薯的主要气象灾害。建议在1月中旬后出苗,可有效降低受低温冻害的影响风险。适宜播种期为12月下旬。
According the investigation and analysis, the winter low-temperature damage is a major meteorological disaster impact of winter potato in Hezhou. Based on the winter low-temperature damage and frost occurrence periods, the damage degree and other aspects of climate in Hezhou were analyzed. For the scientific organization of winter potato sowing and production in Hezhou, we found that the emergence of seedlings after January could avoid or reduce the impact of low-temperature damage, and so late December was the proper seeding time for potato in Hezhou.
