广西栽培龙眼沿用实生苗,投产迟。改用嫁接苗可提早丰产。作者近几年来在产区调查结果表明,龙眼嫁接树具有早结、早丰产的生物学基础。我区三个主要龙眼品种树冠年生长量均达70厘米。广眼品种嫁接树四年生开始投产,树冠2米以上,健壮末次梢60—100条,成穗率达80％以上,单株产量8—15公斤,单果重9—10克,可溶性固形物23％,品质优良,已达到早结、丰产、优质的生产要求。
Guangxi cultivation of longan use of seedlings, put into operation later. Switch to grafted seedlings can be early yield. The author in recent years in the producing areas survey results show that the longan grafted tree with early knot, early bumper biological basis. My area three main longan canopy annual growth reached 70 cm. Wide-eyed species of grafted tree four-year-old began to put into production, crown more than 2 meters, robust end of the next 60-100, spike rate of 80% or more, yield of 8-15 kg per plant, fruit weight 9-10 grams, soluble solids 23 %, Good quality, has reached early knot, high yield, high-quality production requirements.
