| Abstract: | In recent years,with the global warming and the increase of extreme temperature fluctuation in spring,the occurrence of late frost damage to wheat is more and more frequent,which has caused some losses to the production of winter wheat in Zhoukou City,and has become the main disaster factor affecting the high yield of wheat.Based on the comprehensive analysis of the data of wheat growth period and low temperature process,the year and degree of late frost damage of wheat in Zhoukou City from 2010 to 2019,the characteristics and causes of late frost damage of wheat were explored,and the corresponding defense measures were put forward,in order to provide some scientific basis for the local winter wheat production. |
