Embodiment Construction

[0012] A method for grafting and surviving walnut test-tube seedlings outside the test tube, comprising the following steps:

[0013] (1) Cultivation of stock seedlings:

[0014] Choose large walnut seeds with plump kernels, no disease, and clean outer testa as anvil seeds, soak them in warm water for 3 days, and change the water 1-2 times a day. Put the fully water-absorbed seeds into the sterilized wet sand in the greenhouse for germination. The humidity of the sand should not be too high, if you hold it in a ball, it will disperse when you loosen it, and it should be moisturized. After 6-8 days, the radicle grows out, and after 9-12 days, the embryo emerges. When the height of the seedling is 9-11cm, the true leaves have not yet unfolded, and the young stem is still in light red, it can be used as a stock seedling. When taking it out, be careful not to knock off any part of the germ, radicle or walnut, and do not leave it outside for too long to prevent the newly germinat...

Abstract

The invention relates to a walnut seedling cultivating method, in particular to a grafting survival method of walnut test tube seedlings outside a test tube, solving the problems of low propagation coefficient, long seedling growing time, unstable survival rate, and the like of the traditional walnut propagation method. The grafting survival method of the walnut test tube seedlings outside the test tube comprises the following steps of: (1) cultivation of the rootstock seedlings; (2) cultivation of cions, which comprises the obtaining of rootless test tube seedlings and the acclimatization of the rootless test tube seedlings; (3) selection of cortex salicis and preparation and treatment of a growth regulator solution; and (4) grafting comprising the treatment of the cions and the rootstock seedlings: inserting the wedge-shaped parts of the cions into the vertical incisions of the rootstock seedlings during the grafting, then taking out the cortex salicis soaked in the growth regulator solution to wrap the split parts of the rootstock seedlings, and binding from bottom to top by using strip-shaped parafilms. The grafting survival method of the walnut test tube seedlings outside the test tube has fast propagation, can grow the seedlings for one year and enhance the grafting survival rate from 45 percent to more than 85 percent and has the advantages of fast and firm healing of wounds, high operability, simplicity, practicability, low cost, fast propagation, extensive application prospect and obvious economic benefit.

Description

technical field [0001] The invention relates to a method for cultivating walnut seedlings, in particular to a method for grafting and surviving walnut test-tube seedlings outside the test tube. Background technique [0002] Walnut (Juglans regia L) belongs to Juglandaceae Juglandaceae. It is a wide-area economic forest tree species with the highest economic, ecological and social benefits, and it is among the four largest dried fruits in the world. With the widely recognition of the nutritional value of walnuts, the sharp increase in the demand space of the walnut market, and the development and popularization of fruit tree production and management technologies, walnut production is moving from the past extensive and semi-extensive management to scientific management and intensive management. The change is followed by a large demand for fine walnut varieties and their seedlings, but imperfect propagation techniques have always been a huge obstacle restricting the promotion ...
