A grafting method for chestnut trees

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. Background technique [0002] Chestnut is a kind of skin care product for nourishing and treating diseases. Traditional Chinese medicine believes that chestnuts are sweet and warm in nature, and have the effects of nourishing the stomach and spleen, nourishing the kidney and strengthening the waist, strengthening muscles and blood, stopping bleeding and reducing swelling. As market demand continues to increase, more and more farmers are planting chestnut trees. [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 piece may often be embedded on one side of the vascular bundle o...

[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
