Problems solved by technology

Among them, grafting is the main method. Grafting can produce early fruit and maintain the high-quality characteristics of the variety. However, the survival rate of citrus seedlings obtained by grafting is relatively low.

Embodiment 1

[0020] A method for rapid propagation of citrus fruit seedlings, comprising the steps of rootstock selection, scion preparation, seedling grafting, and post-grafting management. The specific operation steps are as follows:

[0021] (1) Rootstock selection: select growth vigorously, grow in a good way, and have no damage by diseases and insect pests. Cultivate citrus tissue cultured seedlings for 3 months, transplant them into seedling cups equipped with seedling substrates, manage them with conventional seedling cultivation methods, and cultivate seedlings after 25 days. When it grows new, it can be used as a rootstock for subsequent use; the seedling-raising substrate is composed of citrus forest topsoil, coconut bran, silkworm excrement and slow-controlled release fertilizer with a weight ratio of 100:30:20:5; the slow-controlled release fertilizer N-P 2 o 5 -K 2 O has a ratio of 22-10-10;

[0022] (2) scion preparation: select for use fruit bearing 2 years, grow vigorous...

Embodiment 2

[0027] A method for rapid propagation of citrus fruit seedlings, comprising the steps of rootstock selection, scion preparation, seedling grafting, and post-grafting management. The specific operation steps are as follows:

[0028] (1) Rootstock selection: select the granulated sugar orange tissue culture seedlings with strong growth, good growth and no pests and diseases, and cultivate them for 2 months, transplant them into the seedling cups equipped with the seedling substrate, manage them with conventional seedling cultivation methods, and cultivate the seedlings after 20 days When new shoots grow out, they can be used as rootstocks for subsequent use; the seedling-raising substrate is composed of citrus grove topsoil, coconut bran, silkworm excrement and slow-controlled release fertilizer with a weight ratio of 100:40:15:4; the slow-controlled release fertilizer N-P 2 o 5 -K 2 O has a ratio of 22-10-10;

Embodiment 3

[0034] A method for rapid propagation of citrus fruit seedlings, comprising the steps of rootstock selection, scion preparation, seedling grafting, and post-grafting management. The specific operation steps are as follows:

[0035] (1) rootstock selection: select the navel orange tissue culture seedlings that grow robustly, grow well, and have no damage by diseases and insect pests, and cultivate them for 3 months, transplant them in the seedling cups that the seedling raising substrate is housed, manage with conventional seedling cultivation methods, and cultivate the seedlings after 30 days. When it is new, it can be used as a rootstock for subsequent use; the seedling-raising substrate is composed of citrus forest topsoil, coconut bran, silkworm excrement and slow-controlled release fertilizer with a weight ratio of 100:20:15:6; in the slow-controlled release fertilizer, N-P 2 o 5 -K 2 O has a ratio of 22-10-10;

Abstract

The invention discloses a method for rapid propagation of citrus seedlings. According to the method, citrus tissue culture seedlings are selected and transplanted in a seedling cultivation cup for cultivation, and when growing new shoots, seedlings serve as stocks for standby application; branches on citrus fruit trees serve as scions; the cleft graft method is adopted for grafting the scions withthe stocks; after grafting, grafted citrus seedlings are cultivated under appropriate illumination and humidity conditions; after buds on the scions grow out, tin foil on the grafted seedlings is removed, and water and fertilizer management and pest and disease control are conducted according to the conventional method. The grafting stocks selected in the method refer to the citrus tissue cultureseedlings, the root system is developed, branches and leaves are lush, stems are thick and strong, the nutritious and vigorous growth is achieved, the requirement of the height and thickness of the stocks in the grafting process can be met in relatively short seedling culture time, the survival rate of grafting is large improved, after the seedlings survive, the quality of the root system of thestocks is good, the grafting seedlings recover and grow rapidly , the time of seedling formation is effectively shortened, the investment cost is reduced, the economic benefits are significant, and strong technical support is provided for accelerating the rapid development of the citrus industry.

Description

technical field [0001] The invention belongs to the technical field of fruit tree propagation, in particular to a method for rapid propagation of 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 spleen, nouri...
