In the main producing areas of Castanea henryi, the clones of Castanopsis fusiforme were selected and selected, and 16 clonal species were established. The clones were tested and analyzed by means of computer simulation. (C-09), yellow hazel (C-06), white Lu Aberdeen (C-07) and oil hazel (C-10) were screened out. The results were as follows: (1) system.

Ceci dit la piste des Corylus asiatiques comme porte-greffes pour les châtaigniers n'est pas idiote.

High-yielding techniques of wild Corylus mandshurica by grafting large-fruit Castanea henryi

Abstract: Wild Corylus mandshurica grafted with large-fruit Castanea henryi through asexual reproduction,the fruits became
large with high and stable yield,and thus significantly improved the economic benefits of Castanea henryi. In this paper,
high-yielding techniques of wild Corylus mandshurica by grafting large-fruit Castanea henryi was summarized, including varie-
ty selection,grafting methods,extermination of disease and pests.
Key words: Corylus mandshurica; large-fruit Castanea henryi; grafting techniques

Through the asexual reproduction of the hazel will be replaced by large fruit cone chestnut, is Castanea henrya
The development of the most direct way, but also the most effective breeding methods
Both to maintain the characteristics of the big fruit, but also to achieve high yield, high yield
Purpose. The author in March 1998 to March 1999 in the water
Source Township, Chuan Shi Township for a large area of wild hair hazel changed to big fruit cone chestnut
Technical test, and achieved good results, graft survival rate of 95%

2 Grafting with cutting method.

2.1 Wild hazel as rootstock, rootstock

High 100 cm. The rootstock cross section is flattened with a grafting knife and then on the rootstock Bark smooth side, vertical from top to bottom 1 knife, longitudinal length About 5 ~ 8 cm. Scion is also selected on the smooth side of the bark, cut 1 long 5 ~ 8 cm cut face, the knife when the oblique deep to the wooden department to the Under the cut, and then in the lower side of the reverse oblique cut a 0. 5 ~ 1. 0 cm short cut Face. To see the rootstock and scion both sides of the formation of the location, scion The formation layer must be aligned with the rootstock forming layer, and its contact surface should be tightly packed Seamless. The scion base is inserted into the bottom of the rootstock cutting surface Cut surface to slightly exposed 0. 5 ~ 0. 8 cm, in order to facilitate the heel spike full healing, Callus early covering the rootstock cross section, to ensure graft survival. Then Spike formation layer after the rootstock formation layer inserted, the binding process may not Touch the displacement, tied to be tight when appropriate, it is necessary to solid and not Damage to the organization, must be the ear piece of mouth together with the buds all wrapped dressing. tie Binding material selection thickness 0. 02 mm, width 4 cm, flexible
New agricultural plastic film, grafted before the cut into different width of the plastic With spare.

2. 2 scion collection and treatment


As the wild hair hazel tree size is not uniform, DBH are
8 ~ 12 cm, so the collection of spikes and access to wild hair hazel rootstock Should have a corresponding ratio, ie 2: 10 (scion diameter 2 cm, rootstock Diameter 10 cm). Too small or too scarce pieces will be due to the life of the stock Force is too strong, the growth of the spike is not suited to the failure caused by change. because This, the scion should be 2 cm in diameter, 20 cm long, collected scion Must be large fruit willow, should be the result of the tree branches, can not be used Buds, branches or vegetative branches.

2.3 Change the time
3 to 4 months each year is the best time to change, then hair hazel open Began to sprout, tree tree sap began to flow, change the survival rate is high.

2.4 Shaping pruning
As the growth of the spike to grow faster, change the second after the first Month began to bud, the first three months there is a new branch formation, and wild The germination of the hazel is very strong, to July nutrient branch to reach 10 Branches. At this time should be based on the state of the growth of the chestnut cultivation Branches, fixed nutrition branches, stable tree, should be in different directions (East, South, west, north) retain 3 to 4 stout branches and cut on Half section, the retention of branches is 30 ~ 40 cm long, all other branches Cut off. After 7 months of germination of the branches, should be in December into the winter Period, Chestnut began to fall after the leaves, the retention length of 60 to 80 cm. 2 to 3 years of pruning pruning in this way to promote
The tree forms a happy crown.
