摘　　要：2021年冬季至2022年春季,国家荔枝龙眼产业技术体系密切关注天气变化、荔枝树成花和开花坐果动态,密切关注技术应用状况,对全国荔枝生产持续进行跟踪调查,形成2022年度全国荔枝生产形势报告。至3月中旬海南各产区荔枝均已进入幼果发育期;粤西、粤中、粤东和桂南、桂东南、滇东南大部分早熟品种已坐果,中晚熟品种进入雌花开放期;长江上游和云南高海拔晚熟产区荔枝尚处于花穗发育期。根据成花和开花情况,预计今年全国荔枝产量253.10万t,比去年减少约一成,接近2020年的255.00万t。From the winter of 2021 to the spring of 2022, the National Litchi and Longan Industry Technology System paid close attention to weather changes, and kept track of national litchi production to form a report on national litchi production situation in 2022. At the middle of March, litchis in all production areas in Hainan have entered the stage of young fruit development;most early maturing varieties in western Guangdong, central Guangdong, eastern Guangdong, southern Guangxi, southeastern Guangxi and southeastern Yunnan have already set fruit, while middle and late-maturing varieties have entered the flowering period of female flowers;litchis in the upper reaches of the Yangtze River and high-altitude late-maturing areas in Yunnan were still in the stage of flower and ear development. According to the situation of flower formation and flowering, the national litchi production is expected to reach 2.531 million tons in 2022, down about 10 percent from last year and close to 2.55 million tons in 2020.
