Influences of High Temperature and Drought Stress on the Longan Industry of Luzhou Area
Luzhou city is a special late maturing production area for longan in China,with a cultivation area of 20 000 hm2 and a perennial yield of 70 000-80 000 t.In recent years,the Luzhou region has experienced sustained high temperatures,low rainfall,and strong sunlight,which has had a significant impact on longan production.This article conducted tracking observation and field research on the development of longan fruits in the region of Luzhou city.It was found that high temperature and drought disasters had a significant impact on the longan industry,leading to delayed fruit development,decreased quality,reduced yield,delayed maturity,weakened tree bodies,and difficulty in extracting nutrient shoots.In response to the impact of high temperature and low rain weather on the longan industry,disaster prevention and mitigation measures and post disaster recovery techniques had been proposed,providing reference for the management of longan fruit development period.
