摘　　要： 针对‘大红袍’荔枝幼青树开展短截花穗的效果分析,在荔枝主产区合江、江阳区进行不同短截时间和短截程度的对比试验。结果显示:在相同的气候和地理条件下,2次短截花穗并留7 cm左右穗长有利于改善花穗结构,提高坐果率,丰产稳产效果明显。 ‘Dahongpao’ is the main cultivar of litchi in Luzhou district of Sichuan Province.This paper reports the experimental results about the effects of floral cluster short-cutting on fruit-setting in recent two years.Treatments of young ‘Dahongpao’ trees by short-cutting floral cluster in different time and different cutting degrees in Hejiang and Jiangyang districts,the main litchi production areas in Sichuan showed preliminarily that the structure of floral cluster was improved by two times short-cutting and about 7 centimeter long floral cluster left in the same climate and geographic conditions.The fruit-setting ratio increased obviously.The effects of high-yielding and regular-bearing were obvious.
