Abstract:

Heat injury is the most important agrometeorological disaster affecting grape production in Guangxi. The authors analyzed the occurrence frequency and spatial distribution of grape heat injury in Guangxi, aiming to provide a scientific decision-making basis for optimizing the distribution of grape industry. Based on the meteorological data of 91 national meteorological observation stations from 1961 to 2016, the frequency of heat injury in flowering bearing period (April to May) and mature harvest period (July to August) was calculated according to the index of grape heat injury grade. The spatial distribution characteristic map of heat injury frequency of grape was obtained based on SURFER technology. The results showed that high temperature became the main meteorological factor restricting grape production in Guangxi. According to the spatial distribution map of grape heat injury in mature harvest period, the areas without heat injury, with mild heat injury, moderate heat injury, severe heat injury and serious heat injury were classified in Guangxi. Most of the grape production areas in Guangxi were concentrated in severe and serious heat injury region. Strengthening the measures against heat injury of grape could improve the quality of grape fruits.
