摘要
泸州市是我国龙眼生产的特晚熟产区之一,栽培面积达 2 万hm2,常年产量7万～8万t.近年来泸州地区持续出现高温、少雨、强日照天气,对龙眼生产造成了较大的影响.本文对泸州市区域内龙眼果实发育开展了跟踪观察和实地调研,发现高温干旱灾害对龙眼产业影响较大,导致果实发育迟缓、品质下降、产量降低、成熟期推迟、树体衰弱、营养梢抽梢难等不良影响.针对高温少雨天气对龙眼产业的影响,提出了抗灾减灾应对和灾后恢复技术措施,为龙眼果实发育期的管理工作提供参考.
Abstract
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.
