Analysis of Guangdong Litchi Production Situation in 2022

Abstract

【Objective】Litchi production in Guangdong Province in 2022 was analyzed, with a view to providing reliable data support for guiding the production of litchi in Guangdong.【Method】Based on the data of litchi cultivars, cultivated area, phenological period, flowering rate, fruit setting rate and expected yield provided by litchi industry alliances, experimental stations and large litchi growers, the yield of litchi in Guangdong in 2022 was predicted.【Result】At the end of May and beginning of June, some early maturing varieties in western Guangdong have begun to mature, and the mid-late maturing varieties have passed the third physiological fruit drop period, and the yield is basically stable. It is estimated that the yield of litchi in Guangdong is about 1.19 million tons in 2022, which is about 18.6% lower than that in last year. Among them, the yields of early maturing varieties Feizixiao and Baitangyin are reduced by 21.11% and 15.52%, respectively. The yields of late maturing varieties Guiwei and Nuomici are reduced by 39.72% and 34.57%, respectively. The yield of Huaizhi is increased by more than 9.61%. In recent years, due to the increase of production area, the yield of the main new varieties of Xianjinfeng, Jingganghongnuo, Fengshanhongdenglong, Lingfengnuo, Guanyinlv and Yujinqiu is increased by more than 10% compared with that in last year. Litchi yield of the early maturing area in western Guangdong is decreased significantly, about 30.25% lower than that in 2021. The yield of late maturing area in eastern Guangdong is stable, basically the same as that in 2021. The yield of mid-late maturing areas in central Guangdong is reduced by 8.35%.【Conclusion】In 2022, Guangdong litchi has good flowering and low fruit setting rate due to low temperature and rainy climate, resulting in lower yield, which is a medium low year in recent 5 years, only higher than the yield of 1.09 million tons in 2019. The flowering period of litchi is over 10 days later than that of the year round, and the listing period is expected to be 10-15 days later.
