Embodiment 1

[0036] In 2013, Chifeng Forest Farm in Inner Mongolia used 15-year-old camphor seeds as rootstocks to graft Korean pine trees.

[0037] details as follows:

[0038] 1. Rootstock selection

[0039] 1) Rootstock selection: Pinus sylvestris, 15 years old.

[0040]2) Rootstock treatment: cut off the first round of horizontal branches at 45 cm, leave 2 rounds of branches, grow for one year, and prepare for grafting from mid-May to early June in the second year.

[0041] 2. Scion selection

[0042] 1) Selection of excellent trees: Aiming at improving the yield and quality of nuts, according to tree height, diameter at breast height, height under branches, location of grafting points, fruiting marks, and fruiting amount, select healthy and pest-free excellent mother trees.

[0043] 2) Scion collection and preservation:

[0044] Scion collection time: collection of scion is carried out after the trees stop growing in the first and middle of December.

[0045] Scion collection sta...

Embodiment 2

[0053] In 2016, the Qiqihar Forest Farm in Heilongjiang Province used 20-year-old sylvestris sylvestris as the rootstock to graft Korean pine excellent ears. details as follows:

[0054] 1. Rootstock selection

[0055] 1) Rootstock selection: Pinus sylvestris, 20 years old.

[0056] 2) Rootstock treatment: truncate the first round of horizontal branches at 35 cm, leave 3 rounds of branches, grow for one year, and prepare for grafting from mid-May to early June in the second year.

[0057] 2. Scion selection

[0058] 1) Excellent tree selection: with the goal of improving nut yield and nut quality, select healthy and pest-free excellent mother trees according to tree height, diameter at breast height, height under branches, fruiting marks, and fruiting amount;

[0059] 2) Scion collection and preservation:

[0060] Scion collection time: collection of scion is carried out after the trees stop growing in the first and middle of December.

[0061] Scion collection standard: ...

Abstract

The invention relates to the technical field of Korean pine grafting, and discloses a method for early fruiting of Korean pine. According to the method, Korean pine scions are grafted to pinus sylvestris rootstocks with an age of 10-30 years, fruiting of Korean pine in the same year or the second year is achieved; and compared with same Korean pine rootstock grafting or young different Korean pine-pinus sylvestris rootstock grafting, the fruiting time in the invention is greatly shortened. The Korean pine is subjected to high-branch, multi-head and high-age different-rootstock grafting in theinvention, so a grafting survival rate is high, cost is low, effect-taking speed is high, economic benefits are good, and the phenomenon of good and lean years does not exist.

Description

technical field [0001] The invention relates to the technical field of Korean pine grafting, in particular to a method for making Korean pine harden in advance. Background technique [0002] Korean pine is the most promising economic fruit forest tree species in alpine regions. Its wood material is excellent, and it is a high-grade material for construction, decoration, and furniture. The seeds are both edible and processed for export, with high economic value. At present, the number of natural Korean pine forests is limited, and only a small part of the Korean pine plantation has just entered the fruiting period, and a small amount of fruiting has begun, and the Korean pine seed production is declining year by year. However, the demand for Korean pine seeds in domestic and foreign markets is increasing day by day, and the price continues to rise. The annual demand for Korean pine is huge, but the output of Korean pine nuts can only meet about 40% of the market demand. The ...
