Evolutionary Characteristics and Countermeasures of Meteorological Disasters for Litchi in Qinzhou of Guangxi Under the Background of Climate Change
Based on the statistics of the date on the meteorological elements in the main litchi producing areas in Qinzhou of Guangxi from 1960 to 2021,combined with the biological characteristics of litchi and the agricultural meteorological disaster indicators,this paper analyzed the evolutionary characteristics and effects of the major agricultural meteorological disasters in Qinzhou.The results showed that the freezing damage in winter and cold damage in spring(flowering stage)in Qinzhou from 1960 to 2021 tended to decline;strong wind damage and the hot damage due to high temperature at the flowering stage was aggravating;the drought during fruit expansion period showed a trend from decline to rise;the frequency of more rainfall in the late period of fruit expansion was high.Therefore,the countermeasures were put forward to provide a scientific reference for the production of litchi and its quality and efficiency.
