英文摘要 | 1. This experiment was carried out in 1957 through 1961 at Chia-yi Agricultural Experiment Station. Chia-yi, Taiwan. 2. In this experiment, primary causes of fruit shedding of lychee growing in Chia-yi were found as the same as those shown by Miss LIU (1953) in Florida. However, the fruit dropping occurred in Chia-yi in the latter period, especially at the maturity of the fruit was found due to the damage of the insect Acrocercops cramerella SNELLEN. About 99.16% of the dropped fruits were seen damaged by this pest at that time. 3. Perforated vinyl bags were used in this experiment to incase the lychee fruits as to protect the fuits from insect damage. Very good results were obtained. Time of incasing the fuit is important, In Chia-yi, early May might be right. Qualities of fruits matured in the vinyl bags were improved. |
