龙眼是我国南方名贵水果。随着生产的发展,新栽幼龄龙眼树越来越多。因此,加强对龙眼幼树的技术管理,使之在两三年内投产,对提高产量,促进龙眼栽培的发展,具有重要意义。一、选择优良的繁育母树利用具有早结果和丰产特征特性的植株作繁殖苗木的材料,其表现为:树形开张、植株较矮、枝梢壮而短、叶片密而实、花序短而宽、挂果较集中、投产较早、丰产性能好,大小年结果现象不明显。二、培育健壮、矮干、枝条开张的无性繁殖的苗木嫁接苗要求 Longan is a precious fruit in southern China. With the development of production, more and more young planted longan trees. Therefore, to strengthen the technical management of sapling tree so that it can be put into operation in two or three years is of great significance to the improvement of output and the development of longan cultivation. First, the selection of excellent breeding mother tree with early results and characteristics of the characteristics of high yielding seedlings for breeding materials, which showed: the tree opened, shorter plants, shoots strong and short, dense and dense leaves, short and wide inflorescence , Fruiting more concentrated, put into operation earlier, high yield performance, the size of the year result is not obvious. Second, to cultivate robust, short stems, branches of vegetative propagation of seedlings grafted seedlings requirements
