Problems solved by technology

[0003] But, the problem that runs into in the process of cultivating chestnut tree grafting is: because the xylem of chestnut stem (branch) is gear-shaped, with general budding method, the inboard bud base depression of bud piece is too deep and the xylem outside cambium of stock is difficult Fitting, the bud pieces may often be embedded on one side of the vascular bundle of the stem of the rootstock, and the cambium is concave, which makes the grafting fail

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with specific examples, and the following examples are only descriptive, not limiting, and cannot limit the protection scope of the present invention with this.

[0025] A kind of grafting method of chestnut tree, the steps are as follows:

[0026] Step 1, preparation before grafting

[0027] (1) rootstock selects annual chestnut saplings, the thickness is about 1.5-1.8 centimeters, cuts off at 20 centimeters from the ground, and makes stock;

[0028] (2) Management of rootstocks. In autumn, apply potassium sulfate type slow-release compound fertilizer to the rootstocks, apply 200 grams per plant, 50 cm away from the trunk, dig three 20 cm deep pits and apply them. After the beginning of winter, pour enough water to freeze and inhibit germination. ;

[0029] (3) For the scion, choose chestnuts with no more than 0.5 cm in length and one section of chestnut as the scion, and store it at low t...

Abstract

The invention provides a grafting method for chestnut trees. The method comprises: a first step of making preparations for grafting, the first steps comprising the substeps of rootstock selection of selecting a chestnut sapling with a thickness of 1.5-1.8 centimeters, which is cut at the position 20 centimeters away from the ground, as a root stock, root stock management of applying compound fertilizer to the rootstock in autumn, and scion selection of selecting a knot-to-knot chestnut scion with the length not greater than 0.5 centimeter as the scion; a second step of performing grafting when a bud of the prepared rootstock is 0.5 centimeter long; a third step of applying varnish to a bare part and a union of the scion; a fourth step of performing post-grafting management; a fifth step of performing management after survival. The step of applying varnish to the bare portion and the union of the scion is used as a water retention method for the grafting and the method can better reduce the evaporation of water of grafting branches, can effectively prevent plant diseases and insect pests in the grafting process and thus can increase the rate of survival of grafting. The effects are especially remarkable in grafting in high temperature seasons of summer and autumn.

Description

technical field [0001] The invention belongs to the technical field of chestnut planting, in particular to a method for grafting chestnut trees.
