Embodiment 1

[0017] Embodiment one, preparation special-purpose seaweed fertilizer

[0018] Add water, ethyl acetate and fresh seaweed to the reaction kettle respectively, add sodium lauryl sulfate after beating together, soak at 35-36°C for 72 hours; then press filter, the filtrate is seaweed extract; finally put The seaweed extract, potassium chloride, magnesium sulfate heptahydrate and calcium powder are mixed, granulated by drum, dried, cooled and sieved to obtain seaweed fertilizer;

[0019] Wherein the mass ratio between fresh seaweed, water, ethyl acetate and sodium lauryl sulfate is 20:60:50:0.1;

[0020] Wherein the mass ratio between seaweed extract, potassium chloride, magnesium sulfate heptahydrate and calcium powder is 50:60:10:20;

[0021] The seaweed refers to one or more than two of kelp, seaweed, kelp, wakame and enteromorpha in any proportion.

Embodiment 2

[0022] Embodiment two, preparation special-purpose amino acid spray irrigation fertilizer

[0023] Mix monomer amino acid, sodium polyacrylate and bishydroxyethylglycine uniformly in a closed environment to obtain amino acid fertilizer; then dissolve the amino acid fertilizer in water 800 times the weight of amino acid fertilizer to obtain amino acid spray irrigation fertilizer;

[0024] Wherein the mass ratio between monomeric amino acid, sodium polyacrylate and bishydroxyethylglycine is 80:5:5.

Embodiment 3

[0025] Embodiment three, the embodiment of grafting and propagating cherry blossoms

[0026] (1) Selection and cultivation of rootstock: Select the current year's cherry root king as the root stock; harvest the ears before germination in spring, cut the annual branches of the annual cherry root king that are robust, full, and free of diseases and insect pests, and cut them into 12cm branches. Cutting was carried out on April 2, 2014, the row spacing of cuttings was 20cm×60cm, the cuttings were vertically inserted into the soil, a bud was left on the ground, pressed firmly, before cutting, the special seaweed fertilizer prepared in Example 1 was applied at 30kg per mu, and after cutting Utilize the special-purpose amino acid spray irrigation fertilizer prepared in embodiment two to irrigate the soil thoroughly.

[0027] (2) Grafting: Grafted on September 5, 2014, grafted cherry blossoms according to the method of one whip bud grafting, and grafted a bud every 15-20cm in a spira...

Abstract

The invention relates to a method for grafting and propagating oriental cherry by use of cherry rootstock. The method comprises the following steps: selecting the current-year cherry rootstock as a rootstock, grafting, cutting and managing, and applying dedicated fertilizers in rootstock cultivating and cutting stages respectively. The affinity of the rootstock is strong, the cutting seedling root system is flourishing, the budding survival rate is high, the grafting survival rate is more than or equal to 98%, the cutting survival rate is more than or equal to 99%, and the transplanting survival rate is more than or equal to 98%. The rootage is easy by cuttage and the root system is large and is increased by 40% or more compared with the root system of a common grafted seedling.

Description

technical field [0001] The invention belongs to the field of tree breeding, in particular to a grafting and breeding method for cherry blossoms. Background technique [0002] Cherry blossoms generally refer to ornamental plants of the genus Prunus in the Rosaceae Li subfamily, and are important flowering tree species in early spring. Because the flowers bloom layer by layer, piece by piece, like clouds and rosy clouds, the flowers are blooming and magnificent, and they have been used more and more in landscaping in recent years. The hard branch cuttings of Yingzhen Wang are very easy to propagate, the root system is developed after cutting, and the resistance is strong. The existing breeding method of cherry blossoms is based on rootstock grafting with cherry, and the existing breeding method has a long seedling cycle, low reproductive efficiency, and low seedling quality, which cannot meet the needs of landscaping projects. Contents of the invention [0003] The technic...
