Embodiment 1

[0021] Embodiment 1, the grafting time is selected June 10-25, the grafting ground is selected in Yantai, Shandong, and stock and scion are selected as follows:

[0022] 1. Rootstock selection: use 2-year-old black pine container seedlings, or 1-year-old light matrix non-woven container seedlings as rootstocks for grafting of coniferous bundles; rootstocks are planted in 2 rows per row, with a plant spacing of 10cm, a row spacing of 30cm, and a row spacing of 70cm; Treat the rootstock; leave the main shoot for grafting on each rootstock, remove and truncate the whorled side branches, and keep 3 to 5 side branches, and the maximum length of the side branches is 20cm; To reach more than 0.5cm;

[0023] 2. Scion selection: select the current year’s leaf bunches on the black pine and red pine trees that are 3-25 years old, and collect when the needle leaf bunches grow more than 1.0 cm in length; the scion picking site is the middle and upper part of the crown, and the fully develo...

Abstract

The invention claims a single brachyblast grafting method for Japanese black pine and Japanese red pine, which is characterized by comprising the steps of cutting tree stocks, taking fringes, splicing and managing after being spliced; a single brachyblast method for cutting buds and taking fringes with a few of xylem is adopted, so that the fringes are easy to take, the grafting speed is fast, and the survival rate reaches up to above 85%; in addition, when the maximum growth is 10.4cm in the first year, the average growth is 6.4cm; and meanwhile, when the maximum growth is 49.4cm in the second year, the average growth is 31cm. The method is simple and the work efficiency is high.

Description

Technical field: [0001] The invention relates to the technical field of forestry, in particular to a method for grafting black pine and red pine single needle bundles. Background technique: [0002] Red pine is an important afforestation pioneer tree species, which is naturally distributed in China, Korea, Japan and Russia. [0003] Ross Far East is one of the main constructing species of temperate coniferous forests in warm temperate coastal areas. [0004] Black pine has been introduced for nearly a hundred years.
