荔枝果实套袋技术研究进展

Research Progress on Bagging of Litchi Fruit

针对荔枝(Litchi chinensis Sonn.)生产过程中,常出现的座果率低、成熟期落果裂果严重、果皮着色不均匀严重影响果实品质等现象和多种病虫害危害,果农在荔枝果实生长期频频喷药保果,这样既增加生产成本,又不符合绿色果品的要求的问题。以华南农业大学为主的科研机构开展了荔枝果实套袋及其配套技术的研究,探索出一套切实可行的荔枝果实套袋技术,并加以示范与应用推广。本文对目前荔枝果实套袋技术的相关研究进展进行了总结分析,并提出以后的发展方向。

There are many factors influencing of litchi production and qualities, such as cultivar, management level, and climatic conditions,which lead to low fruit set, serious fruit abscission during fruit ripeness, and uneven coloring of pericarp. Many kinds of diseases and insects are increasing year by year,especially litchi stinkbug, Conopomorpha sinensis Bradley, Pernophythora litchi. Many growth hormone and spraying pesticides prevent fruit dropping during fruit growth, increase production costs and inconformity of the safety green fruit. To solve these problems, South China Agricultural University and other research institutions carry out some researches of bagging on fruit of litchi. They get some success. Some literatures of bagging on litchi fruit are reviewed, and development direction is put forward.
