荔枝不同时期末次梢开花座果与气象条件的关系

The Relation of the Weather Condition and Fruit-setting of Lichee in Next Year

经调查,荔枝不同时期抽生的末次梢次年开花座果率不同;不同年份同一时期抽生的末次梢其次年开花盛果率也不同;荔枝早秋梢经冬梢处理后,成花率比晚秋梢高,但晚梢晚穗座果率较高,应视末次梢抽生情况及气候条件来决定培养早秋梢还是晚秋梢。花期气候反常时更要加强促花、控梢控穗,适时喷施增加光合作用的药剂,以保证荔枝丰产、稳产。

It was investigated that the percent of flower and setting fruit on end shoot at different phase .The result shows that the percents are different at different phase and at the same phase in different year.The flower percentage is higher on early autumn shoot than that on late autumn shoot by treatment, but the set fruit percentage is higher on the later .The early or late autumn shoot is trained according to the climate condition and the circs. To Strengthen promoting flower ,control the shoot and spike ,spray the photosynthetic chemicals when the climate is deregulation at flower stage.
