Citrus Freezing Damage in Shiyan in 2018: Meteorological Condition Analysis and Preventive Recovery Measures

To rationally and scientifically utilize climate resources, aiming to response to periodic freezing injury, and sustainably develop the citrus industry in Shiyan, we conducted a detailed investigation on the freezing injury in main citrus production villages and towns in Shiyan, on the basis, studied the meteorological characteristics of the freezing injury by using the observational data from the agricultural meteorological station, and according to the grading standards of citrus freezing injury in field and the freezing injury indexes, quantitatively evaluated the performance of 11 main citrus varieties. The results showed that: the meteorological conditions of the freezing injury were low limit minimum temperature, long low temperature duration, large temperature change range, low temperature and high humidity, etc. After discussing the anti- freezing ability of the main citrus varieties, we put forward technical measures for preventing periodic freezing injury and post- disaster recovery from the aspects of citrus varieties, garden planning and field management according to the meteorological factors.
