伏令夏橙成熟期在翌年夏季,正值水果淡季,加之果实品质优良、产量高,深受人们欢迎,目前,已成为世界上栽培面积最大的甜橙品种。但是,在我国,伏令夏橙冬季落果极为严重,通常在30％以上,是生产中急需解决的问题。1986年,我场在中国柑桔研究所的指导下,用2、4—D防止伏令夏橙冬季落果,取得较理想的效果。 In summer, the summer orange season, when the summer orange season, coincided with the low season of fruit, coupled with the fruit of good quality and high yield, was well received by the people. At present, it has become the world’s cultivated sweet orange variety with the largest cultivated area. However, in our country, the decay of orange summer is very serious, usually above 30%, which is an urgent problem to be solved in production. In 1986, under the guidance of China Citrus Research Institute, I used 2,4-D to prevent summer orange deciduous summer decoction, and achieved satisfactory results.
