摘　　要：冻害是冬作马铃薯常遇的气候灾害,通过2016年3月上旬,鄱阳湖棉区马铃薯遭受霜冻灾害和采用适当的补救栽培措施的实践,结果表明:马铃薯产量仍达16830 kg/hm^2,平均收益60588元/hm^2,纯收入43302元/hm^2。因而提出了选用优良马铃薯品种、及时剪除死枯枝叶、排积水、中耕、注意防病控病、加强肥水管理等栽培措施来提高马铃薯抗灾能力,做好保护地马铃薯管理等抗灾措施,以减少霜冻灾害对冬作马铃薯造成的损失。Winter cropping potato oftern encounter freezing injury climate disaster.In early March 2016,the winter cropping potato in Poyang Lake cotton area suffered the freezing injury and local farmers took appropriate remedial cultivation measures.Through this remedy,the potato yield was still up to 16830 kg/hm,average income was 60588 yuan/hm,net income was 43302 yuan/hm.According this practice,this paper put forward some cultivation measures to improve the potato resistance against natural disasters,such as choose good potato varieties,timely cut off the dead leaf litter,drainage water,intertillage,diseases prevention and control,strengthen the fertilizer management etc.Meanwhile,it must do well the management measures to protect the potato to reduce the disaster loss.
