荔枝是我国南方名贵佳果，亦是我市传统名果之一。全市栽培面积900多公顷，大部分是60年代和70年代初种植，都已进入结果年龄。但长期存在单产低、大小年、隔年、甚至数年不结果。为此，我们在洪濑西林果场和康美安排几种药剂进行试验，观察对荔枝控梢、控穗、壮花保果的效果。 Lychee is the precious southern fruit of our country, is also one of the city’s famous fruit. The city’s cultivated area of ​​900 hectares, most of them were planted in the 1960s and early 1970s, have entered the results of age. However, long-term low yield, size year, year after year, or even years without results. To this end, we set up two kinds of medicaments in Hongse Xilin Fruit Farm and Kangmei to test the effect on litchi stalks, spike and flower.
