Problems solved by technology

[0003] When cultivating hemp walnuts, saplings are often planted or grafted. Among them, saplings need to purchase suitable varieties of saplings in advance, but the price of good varieties of saplings is thousands of dollars, so more growers use grafting to cultivate hemp walnuts, mainly The best method is twig budding, but the survival rate of grafting is average, and the saplings are susceptible to freezing damage and air drying, which seriously restricts the mass cultivation of walnut

[0022] Below in conjunction with the examples, the present invention is further described, the following examples are illustrative, not limiting, and the protection scope of the present invention cannot be limited by the following examples.

[0023] A method for grafting and breeding of walnut with high survival rate, the innovation of the present invention is: comprising the following steps:

[0024] ⑴Choose 1 to 2 years old walnut catalpa, plant it in the field from February to March, and water it once;

[0025] (2) Select the branches that germinated after pruning in the previous year as scions, and cut off the wax seals for storage in February to March;

[0026] (3) From March to April, cut the walnut tree at a distance of 30 cm from the ground, cut obliquely at the upper end of the walnut tree at a position of 27 to 29 cm from the backlight side, and cut a crescent-shaped depression on the backlight side of the upper end of the walnut tree. The bark is cut from top to bo...

Abstract

The invention relates to a high-survival-rate breeding method for grafting juglans hopeiensis. The high-survival-rate breeding method comprises following steps: selecting branches cut and sprouted by the last year as scions, storing by a wax seal after cutting and planting juglans mandshurica maxim into large land; cutting off juglans mandshurica maxim from March to April and cutting out of gaps at upper ends; rapidly inserting processed scions into gaps; dipping growth liquid and utilizing plastic strips to wrap up all scions and stocks; and regularly examining the survival rate; timely removing sprout tillers and supplementing water for fertilization and finishing grating after two months. Juglans mandshurica maxim is utilized as stocks. Juglans hopeiensis branches growing robustly are selected as scions. After grating juglans mandshurica maxim and juglans hopeiensis branches, recovery is prompted by growth liquid. Growth is prompted by supplementing water and applying fertilizers. Through a test, the survival rate can be up to 97%.

Description

technical field [0001] The invention belongs to the technical field of walnut planting, in particular to a method for grafting and breeding of walnut with high survival rate. Background technique [0002] Hemp walnut belongs to Juglandaceae, a deciduous tree with single pinnate leaves, the height of the tree is generally 30-35 meters, the bark is silver-gray, 7-11 leaflets, entire or shallow serrated, short hairs on the back of the leaves, and the flowering period is 4 to 5 months, unisexual, hermaphroditic, the fruiting period is October, the fruit is nearly spherical, 3 to 5 cm in diameter, the inner fruit has clear lines, and can be made into handicrafts. According to historical records, there were records of playing with walnuts in the Han and Tang dynasties, and it reached its peak in the Ming and Qing dynasties. Various animals, patterns, etc. are carved on it, entrusting beautiful meanings. [0003] When cultivating hemp walnuts, saplings are often planted or grafte...
