2006～2007年在广西桂林对迟熟蕉柑生理落花落果进行观察研究,探讨其落花落果规律。结果表明:2006年迟熟蕉柑的落花从4月中旬开始,4月下旬结束,4月11～15日和4月18～25日各有1次落花高峰期;2007年的落花从3月中旬开始,至4月中旬结束,落花高峰期在3月29日～4月2日。2006年迟熟蕉柑第1次生理落果从4月中旬开始持续到6月上旬,4月19～25日及5月7～14日为落果高峰期;第2次生理落果从5月上旬开始持续到7月上旬,5月17～23日为落果高峰期。2007年第1次生理落果从3月上旬开始持续到6月上旬,4月1～2日、4月15～17日、5月3～9日为落果高峰期;第2次生理落果从5月1日开始持续到6月上旬,5月4～11日和5月16～24日为落果高峰期。不同年份迟熟蕉柑的生理落果因气温变化剧烈程度不同而不同,两年的坐果率为2.42%～2.46%。
From 2006 to 2007, we observed and studied the physiological drop-blossom fruit of late-ripe banana in Guilin, Guangxi, and discussed its law of falling and falling. The results showed that in 2006, the falling of late ripe banana leaves started in mid April and ended in late April, with one falling peak each from April 11 to April 15 and April 25 to April 25; Beginning in mid-to the end of April, the peak of falling flowers on March 29 to April 2. The first physiological drop of late ripe banana in 2006 continued from mid-April to early June, April 19-25 and May 7-14 as the peak of fruit drop; the second physiological drop started in early May Continued until early July, May 17 to 23 for the peak rush. The first physiological drop in 2007 continued from early March to early June, April 1-2, April 15-17, May 3-9 for the peak of fruit drop; the second physiological drop from 5 From the first day of the month, it lasts until early June, May 4th to May 11th and May 16th to the 24th of April. In different years, the physiological declension of late-ripe banana varies with the severity of temperature change. The fruit-setting rate in two years is 2.42% -2.46%.
