Description
Technical Field
The invention relates to the technical field of plant cultivation, in particular to a grafting method of a congeneric fruit tree variety.
Background
The taxonomic classification of plants is: phylum, subgenus, class, order, family, subfamily, line, family, subfamily, genus and species. The plants can be divided into angiosperms, gymnosperms, bryophytes, ferns and algae plants, wherein the angiosperms can bloom and breed fruits, the gymnosperms originate from ancient times, the ferns comprise Stenoloma chusanum, Stenoloma chusanum and the like, the algae plants have simple structures, the number of the bryophytes is large, and the variety of the bryophytes is more than ten thousand and eighty thousand, so the life is tenacious.
Grafting is one of the artificial propagation methods of plants, that is, the branch or bud of one plant is grafted to the stem or root of the other plant, so that the two parts which are connected together grow into a complete plant. The grafting method is divided into a branch grafting method and a bud grafting method. The grafting is carried out by utilizing the function of wound healing of the plant after being wounded. The grafting is to take the scion from good and good mother, graft the scion to the stock chosen with different grafting methods, can breed the seedling fast, keep the good property of the mother, and improve the resistance of the scion, it is one of the main ways to solve the nursery stock production in the nursery stock trade at present.
During grafting, the scion is tightly combined with the cambium of the stock, and the grafted branch or bud is called as a scion; the grafted plant is called stock or table wood.

Two comparative examples are provided to compare with examples 1-4 of the present invention, namely comparative example 1 and comparative example 2, respectively, the scions of comparative example 1 and comparative example 2 are treated in a different manner from those of examples 1-4 before grafting, the rest of the grafting steps are the same, and the grafting survival rates of examples 1-4 and comparative examples 1-2 are shown in Table 1.
Table 1: survival rate of grafting of examples 1 to 4 and comparative examples 1 to 2
From table 1 it can be seen that: the survival rate of the plants grafted in the embodiments 1 to 4 is high and is not lower than 95%, the survival rate of the plants grafted in the comparative example 2 is 70% after the scions are soaked by clear water, and the survival rate of the plants grafted in the comparative example 1 is 66.7% after the scions are soaked by 40mg/L of naphthylacetic acid and 12mg/L of indoleacetic acid. Therefore, the survival rate of plant grafting can be obviously improved by soaking the auxin before scion, but the survival rate of plant grafting is reduced when the concentration of the auxin is too high.
The grafting method can produce various fruits of the same fruit tree on the same fruit tree, thus fundamentally solving the problem of single fruit variety on one fruit tree; meanwhile, the grafting method can be applied to all plants, so that the same plant flowers can be grown with the same species, the flowering phase of the plants is further prolonged, and the economic value of the plants is greatly improved.
