Problems solved by technology

For the grafting of citrus buds, since the citrus buds are new shoots that have germinated recently from citrus plants, the new shoots are not yet mature at this time, and the degree of lignification is very low, so the grafting of citrus buds cannot be well realized.

Embodiment 1

[0028] A method for grafting and propagating citrus fruit seedlings, comprising the steps of rootstock selection, scion preparation, seedling grafting, and post-grafting management. The specific steps are as follows:

[0029] S1: Rootstock selection: select the young and tender stem section on the top of the mother plant of the fruit-carrying citrus mandarin orange as an explant, and after the stem section is sterilized, cultivate it according to the conventional tissue culture seedling cultivation method for 3 months, and the tissue culture seedling of the Dewo tangerine Then the tissue culture seedlings are transplanted to the seedling cups that the seedling-raising substrate is housed, and the seedling-raising substrate is made up of peat soil, bagasse, biogas bagasse and slow-controlled release fertilizer with a weight ratio of 100:35:12:6, and in the slow-controlled release fertilizer, N-P 2 o 5 -K 2 The ratio of O is 22-10-10, is managed with conventional nursery stock ...

Embodiment 2

[0035] A method for grafting and propagating citrus fruit seedlings, comprising the steps of rootstock selection, scion preparation, seedling grafting, and post-grafting management. The specific steps are as follows:

[0036] S1: Rootstock selection: select the young and knotted stem section on the top of the mother plant of the citrus tangerine with fruit as the explant, and after the stem section is sterilized, cultivate it according to the conventional tissue culture seedling cultivation method for 2 months, and the tissue culture seedling of the Dewo tangerine, Then the tissue culture seedlings are transplanted to the seedling cups that the seedling-raising substrate is housed, and the seedling-raising substrate is made up of peat soil, bagasse, biogas bagasse and slow-controlled release fertilizer in the weight ratio of 100:30:15:6, and in the slow-controlled release fertilizer, N-P 2 o 5 -K 2 The ratio of O is 22-10-10, manages with conventional nursery stock cultivatio...

Embodiment 3

[0042] A method for grafting and propagating citrus fruit seedlings, comprising the steps of rootstock selection, scion preparation, seedling grafting, and post-grafting management. The specific steps are as follows:

[0043] S1: Rootstock selection: Select the young and jointed stem section on the top of the mother plant of the fruit-carrying Citrus tangerine as the explant, and after the stem section is sterilized, cultivate it according to the conventional tissue culture seedling cultivation method for 2 and a half months. The tissue culture seedling of the Dewo mandarin orange, The tissue culture seedlings are transplanted to the seedling cups that the seedling-raising substrate is housed again, and the seedling-raising substrate is made up of peat soil, bagasse, biogas bagasse and slow-controlled release fertilizer in the weight ratio of 100:35:12:5, and in the slow-controlled release fertilizer, N-P 2 o 5 -K 2 The ratio of O is 22-10-10, is managed with conventional nur...

Abstract

The invention discloses a grafting propagation method of citrus fruit seedlings. The method comprises the steps that orah tissue culture seedlings are selected, cultured and are used as stocks when young sprouts grow up, bud shoots which grow up newly at the top of the orah of which apical dominance is removed are used as scions, the scions are tightly combined with the stocks by adopting a grafting method, then grafted fruit seedlings are cultured, and the grafted seedlings of the orah are obtained. According to the grafting propagation method, the orah tissue culture seedlings are used as the stocks, the root system quality of the tissue culture seedlings is good, the grafted seedlings restore quickly and grows up quickly, the seedling formation time is effectively shortened, the input cost is lowered, and the economic benefit is remarkable; meanwhile, the grafting propagation method further has the advantages that the method is easy to operate, low in cost and high in survival rate,the culture time of the stocks in a common grafting method can be effectively shortened, the characteristics of good varieties of the orah are guaranteed, the survival rate of the grafted seedlings is 92% or above, and quick development of the orah industry is accelerated.

Description

technical field [0001] The invention relates to the technical field of fruit seedling propagation, in particular to a method for grafting and propagating citrus fruit seedlings. Background technique [0002] Citrus (Citrus reticulata Blanco) belongs to the Rutaceae plant, also known as citrus. my country is one of the important origins of citrus, with rich citrus resources and a wide variety of fine varieties, with a cultivation history of more than 4,000 years. After long-term cultivation and selection, citrus has become a precious fruit for human beings. More than 30 kinds of human health substances contained in citrus have been isolated, mainly including: flavonoids, monoterpenes, coumarins, carotenoids, propanols, acridones, glycerol glycolipids, etc. The citrus fruit is edible, and the citrus peel, citrus leaves, and citrus roots can be used as medicine, which has different functions such as reducing phlegm, relieving cough, soothing the liver, strengthening the splee...
