Problems solved by technology

However, the existing red cone grafting efficiency is low, the cultivation cycle is long, and the grafting survival rate is low.
[0003] In summary, the problems in the prior art are: the existing red cone grafting efficiency is low, the cultivation period is long, and the grafting survival rate is low
[0004] The scion of existing report red cone grafting comes from sapling rather than the excellent tree (big tree) that grows into a forest and becomes useful. The present invention can retain the good material genetic gene, and the purpose is to cultivate the grafted seedlings by grafting to be used for setting up the scion picking nursery and breeding the good varieties. Seedlings, one is used to establish a clone seed garden, which solves the problem that the scion grafting of excellent trees from Chenglin Chengcai cannot survive; the current grafting time is reported to be March, when all the branches of the red cone in the south have germinated successively Or without bud eyes, grafting cannot survive at all

Embodiment 1

[0038] Experimental situation of red cone grafting

[0039] At the beginning of February 2015, at Manguang Flower and Tree Nursery Professional Cooperative in Xianyou County, Fujian Province, more than 100 plants were grafted with branches from the upper part of the canopy of an excellent tree (20 years old) collected from Jinshan Forest Farm, and 2-year-old red cone seedlings as rootstocks. , 40 days after grafting, the average spike germination rate reached 60% (some are fake), and the survey preservation rate of 4 months and 8 months after grafting was only 30%. In view of the low survival of grafting, from the end of December 2015 to the middle and late January of 2016, the grafting work continued on the principle that the branches had not yet germinated.

[0040] The purpose of grafting: to carry out grafting experiments and explore grafting techniques. Emphasis is on using excellent tree scion grafting in the nursery field, which will be used in the next step to build a...

[0057] 1. Experimental situation of red cone grafting

[0058] On January 22, 2016 and March 15, 2016, at the Manguang Flower and Tree Nursery Professional Cooperative in Xianyou County, Fujian Province, the upper half of the canopy of an excellent tree (20-25a old) collected from Jinshan Forest Farm was used to grow two-year-old The red cone seedlings were used as rootstocks for grafting experiments in 2 batches of 339 plants. 40 days after grafting, the average spike germination rate of grafted on January 22, 2016 reached more than 70% (some fake work), and grafted on March 15 Almost all of them died. 3 months investigation after grafting, the survival rate of scion thickness 0.2-0.5cm reaches 72%, and the survival rate of thickness greater than 0.5cm or less than 0.2cm has only 10-20%. Explain, scion thickness should be controlled at 0.2-0.5cm the branch that gives birth to in that year, and grafting time will be controlled before and after the great cold.

Abstract

The present invention belongs to the technical field of castanopsis hystrix grafting, and discloses a castanopsis hystrix grafting method and system. The method comprises the steps of grafting time selection, stock selection, cuttings selection, grafting operation and post-grafting management. Cuttings having at least one spore are adopted by the scion for grafting, the castanopsis hystrix grafting survival rate can be obviously increased, and grafting efficiency is high. The castanopsis hystrix grafting is carried out at the end of December to the middle and last ten-day of January, namely 2-5 days before and after the Great Cold, the principle that branches are not yet germinated and bud eyes are plump is adopted, and the survival rate is effectively increased. The method has the characteristics that good germplasm materials of castanopsis hystrix are cultivated and preserved in a short period, shaping can be rapid, fructification can be carried out ahead of time, operation is simple, and cost is low, the survival rate according to the method reaches more than 70%, and the method is suitable for grafting of castanopsis hystrix nursery seedlings. Grafted seedlings are cultivated for establishing an improved variety cutting orchard and a clonal seed orchard. The method is an effective approach for exsitu-conservation and utilization of the good germplasm materials of castanopsis hystrix, and is an agroforestry genetic inheritance and improvement technology with extremely high practicability.

Description

technical field [0001] The invention belongs to the grafting technology in the field of forestry biotechnology, and in particular relates to a red cone grafting method. Background technique [0002] Red cone, tree, up to 25 meters, diameter at breast height 1.5 meters, current year branches purple-brown, slender, same as petiole and inflorescence rachis. Leaves papery or thin leathery, lanceolate, sometimes obovate-elliptic, base very short and pointed to nearly round, one side slightly shorter and slightly oblique, entire or with a few lobed teeth, midrib at the leaf Face sunken, young leaves abaxially at least along midrib with deciduous pubescence and loose and thick, or relatively compact and thin reddish-brown or brown-yellow flaky wax scales; petiole rarely up to 1 cm long. Male inflorescences are panicles or spikes; female spikes are located in the upper leaf axils of male inflorescences, with 3 or 2 styles, spreading obliquely. Infructescence up to 15 cm; shell wit...
