摘要:

 【Objective】A comprehensive survey was carried out to investigate the adverse effects of severe frost and prolonged winter chill on litchi and longan production in Guangxi from 15, December 2010 to January 2011. 【Method】The survey included northern litchi and longan growing areas in Tengxian, Guiping, Pingnan,Wuxuan and Xiangzhou counties (Cities) of Guangxi. 【Result】The statistical data showed that about 13.30 thousand hectares (kha) of litchi and longan fruit trees were injured or damaged accounting for 30% of the total growing area (45.73 kha). In Xiangzhou, Wuxuan and Tengxian counties, the total damaged area was the highest for 670, 1667 and 2887 ha, accounting for 100, 100 and 67% of total area, respectively. The injured shoots ranged from 79.07-100.00%. The severity of damages was followed by Pingnan and Guiping, where damaged area was 3467 and 4667 ha and accounted for 22 and 20% of total area, respectively, and the injured shoots ranged from 76.45-99.62%. Litchi was more seriously injured than longan, and low-lying orchards were more seriously injured than hillside orchards. 【Conclusion】Some suggestions have been given in order to manage and control the frost induced damages on litchi and longan fruit tress which includes timely irrigation and spraying water-fertilizers; timely loosening and covering soil over the roots, applying fertilizer as topdressing, making grading nurse of tree according to different frost damage degree, strengthening protection of tree and control of disease and insect pests.
