Embodiment 1

[0018] The grafting method of present embodiment walnut comprises the following steps:

[0019] A, the processing of scion: the scion of gathering is put into cellar, according to the mode of spreading one deck of wet sand one deck scion, bury scion with wet sand, the humidity of described wet sand is with 50%~60%, and the depth of burying is One-half the length of the scion;

[0020] B, the pretreatment of stock: choose the common walnut tree that growth period is 5 months to be stock, retain 3 growth buds on the stock, 2 days before grafting, spray naphthalene acetic acid slightly on stock top, use polytetrafluoroethylene microporous film rootstock wrap;

[0021] C, Grafting: Carry out grafting in February, cut off the dry part of the scion, and then soak in the nutrient solution; the nutrient solution contains sucrose, potassium nitrate, potassium dihydrogen phosphate, calcium nitrate and water; every 1L of the nutrient solution Contains 150 grams of sucrose, 50 grams of ...

Embodiment 2

[0024] The grafting method of present embodiment walnut comprises the following steps:

[0025] A, the processing of scion: the scion of gathering is put into cellar, according to the mode of spreading one deck of wet sand one deck scion, bury scion with wet sand, the humidity of described wet sand is with 50%~60%, and the depth of burying is Two-thirds of the scion length;

[0026] B, the pretreatment of stock: choose the common walnut tree that growth period is 6 months to be stock, keep 3 growth buds on the stock, 3 days before grafting, spray naphthalene acetic acid slightly on stock top, use polytetrafluoroethylene microporous film rootstock wrap;

[0027] C. Grafting: Carry out grafting in March, cut off the dry part of the scion, and then soak in the nutrient solution; the nutrient solution contains sucrose, potassium nitrate, potassium dihydrogen phosphate, calcium nitrate and water; the nutrient solution per 1L Contains 170 grams of sucrose, 55 grams of potassium ni...

Embodiment 3

[0030] The grafting method of present embodiment walnut comprises the following steps:

[0031] A, the processing of scion: the scion of gathering is put into cellar, according to the mode of spreading one deck of wet sand one deck scion, bury scion with wet sand, the humidity of described wet sand is with 50%~60%, and the depth of burying is One-half the length of the scion;

[0032] B, the pretreatment of rootstock: choose the common walnut tree that growth period is 8 months to be rootstock, keep 2 growth buds on the stock, 2 days before grafting, spray naphthalene acetic acid slightly on the top of the rootstock, use polytetrafluoroethylene microporous film rootstock wrap;

[0033] C. Grafting: Grafting: Carry out grafting in February, cut off the dry part of the scion, and then soak in the nutrient solution; the nutrient solution contains sucrose, potassium nitrate, potassium dihydrogen phosphate, calcium nitrate and water; The nutrient solution contains 200 grams of su...

Abstract

The invention discloses a walnut grafting method, and relates to the technical field of plant cultivation. According to the method, naphthylacetic acid is sprayed at the top of rootstocks, scions are soaked in nutrient solution with sucrose, potassium nitrate, monopotassium phosphate, calcium nitrate and water, so that the rootstocks and the scions absorb sufficient nutrition, survival rate is increased, the rootstocks are wrapped by the aid of polytetrafluoroethylene microporous films, permeability and water resistance of the polytetrafluoroethylene microporous films are good as compared with traditional plastic bags, and the problem of low survival rate of the scions caused by high temperature in the plastic bags is solved.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a method for grafting walnuts. Background technique [0002] The cultivation of walnut seedlings is a key step in cultivating walnuts. However, the quality of walnut fruit produced by walnut trees cultivated from walnut seeds is poor. In order to obtain higher quality walnuts, it is necessary to breed them by grafting. [0003] A kind of existing walnut grafting method, this method puts the picked scion into airtight plastic bag immediately, treats the scion to carry out grafting again in the first ten days of a month to the last ten days of a month in May, and covers a plastic bag above the scion to form an airtight space, the place to be grafted When the tender stems begin to thicken, untie the plastic bag. The scion of this kind of grafting method is easy to obtain, but cover a plastic bag above the scion to form a closed space, the temperature in the plastic bag will be hig...
