Problems solved by technology

These two methods of grafting melon buds will lead to partial liquid discharge from the incision of the rootstock, and the problem of interface rot will occur after the melon buds are grafted, which will affect the survival rate of grafting; therefore, technicians often choose sunny days for grafting to reduce the probability of seedling rot after grafting; When rotten melon buds are found, immediately remove the whole rootstock and discard it to prevent infection of other grafted seedlings
[0005] In the prior art, there are no good control measures for the grafted seedlings whose joints have rotted. Most of them choose to pull out the rotten seedlings to keep other grafted seedlings; If it is removed, the loss will be serious

Embodiment 1

[0030] Embodiment 1 A kind of watermelon grafting seedling raising method

[0031] Step 1. Rootstock selection

[0032] When grafting, it is necessary to choose special varieties of excellent disease-resistant rootstocks; a large number of experiments and production applications show that the effect of using Yeersan pumpkin is the best.

[0033] Step 2. Preparation before grafting

[0034] (1) Preparation of rootstock seedlings

[0035] Pumpkin rootstock seeds generally have thick seed coats and are difficult to absorb water. In order to improve the germination rate and germination potential of rootstock seeds and promote seed coat cracking, they must be treated with a seed treatment agent and soaked in warm water.

[0036] The seed treatment agent is formed by mixing the following raw material components in parts by weight:

[0037] 4 parts of choline chloride, 8.2 parts of ethalicin, 13.6 parts of sodium lignosulfonate, 1.6 parts of amylase, 1.0 parts of neutral cellulase...

Embodiment 2

[0084] Example 2 Single factor analysis experiment of rootstock

[0085] Adopt the method of grafting and raising seedlings of embodiment 1, only change the rootstock variety, carry out embodiment 2-4; The rootstock variety adopted in embodiment 2-4 is as shown in Table 1;

[0086] Table 1

[0087]

[0088] After the test, the grafted seedlings cultivated by the watermelon grafting and seedling raising method of embodiment 2-4, 10 days after the grafting, the statistical grafting survival rate and the stock cotyledon preservation rate are shown in Table 2;

[0089] Table 2

[0090]

[0091] As can be seen from the above table, Yeersan pumpkin has the highest survival rate for rootstock grafted watermelon, and the stock cotyledon preservation rate is the highest, it can be seen that the grafted rootstock is preferably Yeersan pumpkin.

Embodiment 5

[0092] Example 5 Grafting factor analysis experiment

[0093] Adopt the grafting seedling raising method of embodiment 1, only change the grafting time in step 3 grafting and inserting angle, carry out embodiment 5-7; The grafting time and inserting angle that embodiment 5-7 adopts are as shown in Table 3;

[0094]

[0095] After the test, the grafted seedlings cultivated by the watermelon grafting and seedling raising method of embodiment 5-7, 10 days after the grafting, the statistical grafting survival rate is shown in Table 4;

[0096] Table 4

[0097]

[0098] As can be seen from Table 4, the grafting time is preferably that the rootstock seedling grows 3 true leaves, and when the first true leaf grows to 4 centimeters long; the insertion angle is preferably 60 °.

Abstract

The invention provides a watermelon grafting seedling growing method. The watermelon grafting seedling growing method comprises the steps of stock selection, preparation before grafting, grafting, seedling growing and cultivation before grafting; grafting comprises selection of grafting time, stock treatment, inserting and grafting opening treatment; the grafting time is selected when scion cotyledons come out of soil, seed coats shed, and two cotyledons do not open; grafting is conducted when 3 main leaves come out of stock seedlings and the first main leaf grows to 4 cm in length; in the stock treatment, the growth point and the main leaves are cut; seedling growing comprises temperature management, humidity management, illumination management, ventilation and water-fertilizer management. The watermelon grafting seedling growing method effectively lowers the incidence of grafting rot of watermelon grafting seedlings and increases the survival rate of the grafting seedlings.

Description

technical field [0001] The invention relates to a watermelon grafting and seedling raising method, belonging to the technical field of plant planting. Background technique [0002] Grafting, one of the artificial vegetative propagation methods of plants. That is, the branches or buds of a plant are grafted onto the stems or roots of another plant, so that the two parts that are joined together grow into a complete plant. The methods of grafting are divided into branch grafting and budding. When grafting, the cambium of the scion and the rootstock should be closely combined to ensure the survival of the scion. The grafted branches or buds are called scions, and the grafted plants are called rootstocks or table trees. After grafting, it becomes the upper part or top of the plant body, and the rootstock becomes the root part of the plant body after grafting. [0003] Watermelon grafting is the purposeful grafting of watermelon buds or branches onto rootstocks such as gourds...
