The invention discloses a non-tissue-cultured walnut micro-
cutting grafting seedling raising method. A walnut grafted
seedling which is cultured by using soil is used as a female parent tree for producing micro-cuttings, the
nutrition of the tree is increased by flexibly adopting a
rhizosphere fertilization mode and a leaf spray fertilization mode according to the growth vigor of a nursery stock, the
germination speed is high, and the production period of the micro-cuttings is short; the female parent tree is planted in a plastic
greenhouse and an
open field respectively, so that
complementation in time can be realized, the production time of the micro-cuttings is prolonged, and the cost is reduced; the walnut grafted
seedling which is cultured by using soil is used as the female parent tree for producing the micro-cuttings, the produced micro-cuttings has the base
diameter of greater than 0.4 cm, is well matched with seedlings in the roughness, and is robust in the growth, and thus the problems of leaf yellowing, withering, slimness and
weakness and the like of the tissue-cultured micro-cuttings which occur frequently are solved; the method is easy to operate without specialized training, and the
grafting survival rate of normal personnel reaches 79 percent; the requirements on environment conditions are loose, i.e., the environment conditions can be spring, summer and autumn, the micro-cuttings can be produced in the outdoor fields under natural conditions, and the propagation coefficient is large; and by applying
ethephon, the
growth speed of the micro-cuttings is flexibly controlled, and adjustment and control are performed to enable that the production of the micro-cuttings is consistent with that of the seedlings.
