Analysis of the National Litchi Production in 2024 and Management Suggestions
According to the survey conducted at the end of March in 2024,the litchi cultivation area in China was 7.8513 million mu.Based on the flowering situation,it was predicted that the total litchi production in China would be 1.781 million tons in 2024,a decrease of 45.94％compared to the previous year.Among them,the predicted litchi production in Guangdong would be 876,400 tons,416,100 tons in Guangxi,228,100 tons in Hainan,117,800 tons in Fujian,78,300 tons in Yunnan,and 64,300 tons in Sichuan.The production reduction in Guangdong and Guangxi was significant.If the timelines before May,May to July,and after July were used as early,mid,and late-ripening periods of litchi fruit,the early,mid,and late-ripening ratio would be 47.1∶41.9∶11.0 in the coverage area of this year's comprehensive experimental station.By variety,the predicted production was as follows:'Feizixiao'with 628,500 tons,'Heiye'with 183,000 tons,'Huaizhi'with 93,500 tons,'Baitangying'with 79,900 tons,'Guiwei'with 50,500 tons,'Shuangjianyuhebao'with 26,100 tons,'Dahongpao'with 17,900 tons,'Baila'with 15,200 tons,and'Nuomici'with 15,700 tons.The mid and late varieties such as'Heiye','Huaizhi','Guiwei','Nuomici'and'Jizuili'had a production reduction ranging from 60％to 80％.The analysis indicated that the delayed maturity of the last autumn flush and the warm winter might be the primary factors influencing litchi flowering of this season.Consequently,some relevant management technical suggestions were proposed.
