一、空中取技，培育苗本首先一选择优良橘树（如兴津早生等）的2－3年生果技作为砧木。从其根部做环状剥皮，可制止枝干中营养液的回流。其次，在果枝枝头方向一侧枝干两处，用刀对称削剥数厘米树皮作为嫁接用的诸插口，如图1所示。嫁接用的穗木为积（或称构橘）树苗。为了防止 First, aerial abstraction, nurturing seed First choice of good orange (such as Xingjin early life, etc.) 2 - 3-year-old fruit as a rootstock. Ring peeled from its roots, can stop the nutrient solution in the branches back. Second, branches were dried at one side of the branches of the fruit branches, and a few centimeters of the bark were symmetrically cut by the knife as the jacks for grafting, as shown in FIG. 1. Grafting with spike wood for the plot (or structure orange) saplings. to prevent
