论龙眼、荔枝生产的若干农业气象问题及对策

Discussion On Some Agricultural Meteorological Problems And The Countermeasures In The Production Of Longan And Litchi

通过对龙眼、荔枝长期观察结果的分析 ,认为树体和花序受寒 (冻 )害、冬季连阴雨寡照致使成花率低 ,花期低温阴雨或高温干旱天气 ,使果树不能正常开花座果或果实败育等 ,是广西龙眼、荔枝生产上的主要农业气象问题。

The analysis of the long-term observation results of longan and litchi shows that the main agricultural meteorological problems in the production of longan and litchi in Guangxi are that the tree bodies and inflorescence suffer from cold, the flowering rate is low due to the run of wet weather and lack of sunlight in winter, and that the wet weather with low temperature or draught weather with high temperature are unfavorable for the trees to bloom and set fruits normally. This article also probes into the arising mechanism and the countermeasures of these problems.
