This study makes known that the new technique of raising seedlings of longan by micro-air-layering method which uses tender and short cutting without soil in the root-growing-matrix.①Two-Bud-Cutting can be employed, and the root-growing-days,the twig-tip-growing and the transplanting survival rate are neatly the same respectively as the traditional air-layering method that uses Iong cutting.②The cuttings,diameters are between 0.4cm and 0.7cm,grow roots well. And the smaller in diameter, the higher the root-growing rate.③The best root-growing-matrix is the mixture with half cotton and half degreasing cotton,and by using it the root-growing rate is 92.4%in 106 days.④The cutting,s circle wound should be treated with 400mg/kgIBA.The root-growing-rate is 92.2%in 104 days with twig tip growing at the same time.⑤After the second root growth, the seedlings of micro-air-layering can be cut from mother tree,then cultivat-ed in the nursery. Managed scientifically,the new roots can grow in 10 days and the survival rate reaches 85%and the height of seedlings can reach 80cm after one year.
