摘　　要：2021年1月20日凌晨4:00—6:00,马山县古零镇马铃薯种植基地出现-4℃的低温霜冻天气。调查发现,桂农薯1号马铃薯的平均受害株率为19%,极显著低于广西主栽品种费乌瑞它(p<0.01);桂农薯1号受害植株的受害程度亦比费乌瑞它轻;桂农薯1号收获期产量为1959.07 kg/667 m2,比费乌瑞它增产31.00%,说明桂农薯1号马铃薯具有较强的抗低温霜冻能力,受害后仍能获得较高的产量,适宜在我国马铃薯秋冬作地区种植。针对低温霜冻发生前期和后期的危害特点,提出相应的防控技术,为有效防控马铃薯低温霜冻提供参考。On 20 January 2021,from 4:00 am-6:00 am,a low-temperature frost of‒4℃occurred at the potato planting base in Guzhe Town,Masan County.The survey found that the average damage rate of Guinongshu No.1 potato was 19%,which was significantly lower than that of Favorita,the prime cultivar in Guangxi(p<0.01);the damage level of Gui Nongye No.1 plants was also less than that of Favorita;the output of Guinongshu No.1 at harvest was 1,959.07 kg×667 m^(‒2),which was 31.00%higher than that of Favorita,indicating that Guinongshu No.1 has strong resistance to low-temperature frost and can still obtain high yield after being damaged,and is suitable for the autumn and winter potato planting areas in China.Given the damage characteristics in the early and late stages of low-temperature frost,corresponding prevention and control techniques were proposed to provide a reference for effective prevention and control of low-temperature hurts on potatoes.
