Korean pine same-stock and different-stock double-root grafting cultivation technology

Abstract

According to the novel red pine fruit forest grafting method, red pine scions are grafted through same and different rootstocks, the incompatible death phenomenon in the later stage of different-rootstock grafting of pinus sylvestris is overcome, and therefore the development area of a red pine fruit forest is expanded.

Description

Technical Field

[0001] The invention relates to promoting the affinity of a different rootstock grafted Korean pine fruit forest, grafting, containerizing and cultivating Korean pine grafted seedlings in the same year. Background Art

[0002] At present, there are two forms of grafting in Korean pine orchards. One is the same rootstock grafting, which has good affinity but limited cultivation area, and arid areas are not conducive to the growth of Korean pine. The other is different rootstock grafting, which uses Larix gmelinii as the rootstock to graft Korean pine. The deep roots of Larix gmelinii are used to expand the cultivation area, and it grows well in arid areas. However, the affinity of different rootstock grafting is poor in the later stage, and some trees have died. Summary of the invention

[0003] At present, the grafting cultivation of red pine nut forests generally adopts the same rootstock or different rootstock grafting. Both grafting methods have limitations and advantages and disadvantages in cultivating red pine nut forests. The preservation rate in arid areas is low. Through years of experiments, the double roots of red pine and Larix gmelinii are grafted onto one scion of red pine to form the same and different rootstock double roots, which not only solves the problem of affinity, but also uses the deep root characteristics of Larix gmelinii to solve the problem of poor growth and later death in arid areas, so that the later preservation rate reaches more than 80%. DETAILED DESCRIPTION

[0004] In winter, scions are collected and stored at low temperatures. In spring, from April 1 to early June, there are two modes of grafting:

[0005] 1. The scion is thick, and one scion is grafted symmetrically on two rootstocks. The grafting method is cambium grafting or cleft grafting.

[0006] 2. The scion is equivalent to the rootstock. Two different rootstocks are first grafted close together, and then the scion is grafted on the same rootstock. The grafting method is cambium grafting or cleft grafting.

[0007] After grafting, place in container and manage as container seedlings. You can also place two rootstocks in container before grafting.

[0008] The grafted Korean pine seedlings cultivated in this way not only grow well in arid areas, but also have a later preservation rate of over 80%.
