Abstract

The invention discloses a process for grafting ponkan branches onto pear trees. The process comprises the following steps: preparing stocks, namely taking strong green branches which are longer than 20cm and bear no fruit continuously for 2-3 years of the pear trees as the stocks; cultivating and inoculating scions, namely cutting off the ponkan branches, naturally dewatering the ponkan branches in the dry environment with the temperature of 20-28 DEG C, soaking the dewatered branches in a sterilizing agent with a concentration of 4-8% for 8-15 minutes, then washing the branches by clear water, and drying the washed branches; grafting, namely sawing holes in the top ends of the stocks from the beginning of March to the beginning of April, cutting the sides of the scion branches against buds into large oblique planes, soaking the scion branches in a nutrient solution for 1-2 minutes, inserting the oblique planes of the scion branches into the skin layer of the stocks, and then tightly binding the scion branches by agricultural plastic mulching films. According to the process for grafting the ponkan branches onto the pear trees, the success rate of grafting ponkan is improved by reducing influence factors of the natural environment; the ponkan breeding period is shortened; the breeding efficiency is improved; ponkan fruits produced by the pear trees are rich in juice, and rich, sweet, crisp, tender, soft, tasty and refreshing in taste.

Description

The technique of pear tree grafting Pon mandarin orange branch

Technical field

The invention belongs to the technical field of grafting, specifically relate to the technique of a kind of pear tree grafting Pon mandarin orange branch.

Background technology

Pon mandarin orange has another name called ponkan, the thin easy stripping of skin, color and luster is delicious, pulp is orange red, juice is many, tissue tight, dense sweet tender and crisp, change slag tasty and refreshing, seed is few, and have medicinal efficacy, be applicable to the growth of southern each province, and one of fruit-tree grafting vegetative method that is fruit tree, namely take branch on improved seeds plant or bud grafting to the suitable position of another plant, both are made to combine and generate new plant, the branch connected or bud are called scion or budder, stock is with scion or the plant connected of buddering, adopt the new plant of propagation by grafiting, the merit of its maternal plant can be kept to utilize again the advantageous feature of stock, temporarily be busy with the process of pear tree grafting Pon mandarin orange at present.

Summary of the invention

In view of this, a kind of pear is the object of the present invention is to provide to set the technique of grafting Pon mandarin orange branch, the technique of this pear tree grafting Pon mandarin orange branch reduces the influence factor of natural environment, improve the success rate of Pon mandarin orange grafting, shorten Pon mandarin orange breeding cycle, improve breeding efficiency, make the Pon mandarin orange juice of the fruit of the product on pear many, dense sweet tender and crisp, change slag tasty and refreshing.

In order to achieve the above object, the technique of a kind of pear tree of the present invention grafting Pon mandarin orange branch, its step is as follows:

1) preparation of stock: select pear to set length for giving birth to branches as stock for more than 20 centimetres continuous 2 ~ 3 years fruitless stalwartnesses;

2) cultivate scion: Pon mandarin orange branch is cut natural-dehydration under temperature is the dry environment of 20 DEG C ~ 28 DEG C, with concentration be 4% ~ 8% bactericide will dewater branch immersion 8 ~ 15 minutes, then with clear water flushing, again branch is dried after cleaning, waits to be grafted;

3) grafting step: grafting time is the first tenday period of a month in the first tenday period of a month in March to April of pear tree leaf renewal, in stock top saw kerf, scionwood back of the body bud side is whittled into a large inclined-plane, scionwood soaks 1-2 minute in nutrient solution, solution temperature remains on 35 ~ 40 DEG C, then scionwood inclined-plane is inserted stock pork skin layer from top to down, then use agricultural mulching bondage tight.

Further, in step 2) in, scion branch is set to the branch biennial female branch having two annual branches, and cuts apart from annual bifurcation 2 ~ 3cm at biennial female branch.

Further, in step 2) in, the concentration of bactericide is set to 5%, and dehydration branch soak time is 10 minutes.

Further, in step 2) in, scion branch late Febuary ~ the first tenday period of a month in March carry out when scion-seed tree is in resting state hand shears or averruncator preparation, then dewater in greenhouse.

Beneficial effect of the present invention is:

The technique of pear tree grafting Pon mandarin orange branch of the present invention reduces the influence factor of natural environment, improves the success rate of Pon mandarin orange grafting, shortens Pon mandarin orange breeding cycle, improve breeding efficiency, make the Pon mandarin orange juice of the fruit of the product on pear many, dense sweet tender and crisp, change slag tasty and refreshing.

Embodiment

The technique of a kind of pear tree of the present invention grafting Pon mandarin orange branch, its step is as follows:

1) preparation of stock: select pear to set upper length for for more than 20 centimetres continuous 2 ~ 3 years raw branches of fruitless stalwartness are as stock, when not affecting the output of pear, enriching the fruit of fruit tree, improving the product of fruit tree;

2) scion is cultivated: scion branch is set to the branch biennial female branch having two annual branches, and cut apart from annual bifurcation 2 ~ 3cm at biennial female branch, scion branch late Febuary ~ the first tenday period of a month in March carry out when scion-seed tree is in resting state hand shears or averruncator preparation, then dewater in greenhouse, Pon mandarin orange branch is cut natural-dehydration under temperature is the dry environment of 20 DEG C ~ 28 DEG C, be that dehydration branch is soaked 10 minutes by 5% bactericide by concentration, then rinse with clear water, again branch is dried after cleaning, wait to be grafted;

The technique of pear tree grafting Pon mandarin orange branch of the present invention reduces the influence factor of natural environment, improves the success rate of Pon mandarin orange grafting, shortens Pon mandarin orange breeding cycle, improve breeding efficiency, make the Pon mandarin orange juice of the fruit of the product on pear many, dense sweet tender and crisp, change slag tasty and refreshing, the fruit on pear tree enriches, and improves output.

What finally illustrate is, above preferred embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although by above preferred embodiment to invention has been detailed description, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from claims of the present invention limited range.
