Which is better, seedling or grafted seedling? What are the differences? Is it better to have sweet-scented osmanthus original or grafted?

There is a saying: good seedlings come out of good land, and good seedlings bear good fruit. The advantages and disadvantages of seedlings and grafted seedlings have always been the key issues considered by garden seedling purchasers. Which is better between seedlings and grafted seedlings, and what is the difference between them? Is it better to have sweet-scented osmanthus original or grafted?

Generally speaking, the disease resistance of seedlings is better, whether on forestry Camellia oleifera seedlings or agricultural fruit seedlings, the fruit performance and fruit winning rate will be better, so seedlings and grafted seedlings have their own advantages. In practical production, if the seedlings are grafted, the original advantages of seedlings will be retained.

Seedlings and grafted seedlings are the same in melons, for example, when watermelons, cucumbers and tomatoes are planted, soil diseases are more serious. In order to improve disease resistance, we use felt wood from pumpkin and other melons, and then grafted watermelon seedlings. This will improve its disease resistance.

1. Methods of reproduction

The seedling includes the sowing seedling, the wild seedling and the transplant seedling transplanted with the above two kinds of seedlings. The seedlings obtained by seed propagation are different from the cutting seedlings and grafted seedlings obtained by asexual reproduction.

Grafted seedling, a seedling in which the branches or buds of one variety are attached to the branches or roots of another plant and grow after the joint heals.

2. Quality is good or bad

The seedling has the characteristics of exuberant growth, developed root system, long life and so on. When used as propagation material, the source is abundant, the method is simple and the cost is low. The disadvantage is that the purity of the variety is not high, it is easy to appear variety, the design and color is not pure and so on.

Grafted seedlings can maintain the excellent characters of mother trees, have strong adaptability and early fruiting age, so they are widely used in fruit tree cultivation. The disadvantage is that the cost is high, compared with seed reproduction, reproduction speed and reproduction quantity are not good.

3. The survival rate is high or low

Among the seedlings sold, the survival rate of all grafted seedlings is better than that of real seedlings, including all kinds of fruit trees, valuable ornamental flowers, bonsai and so on.

4. The price is high or low

In seedlings, most of the price factors are determined by the quality of seedlings and the scarcity of stock, and there are exceptions. For example, some people think that seedlings are better than grafted seedlings, so he is willing to pay a high price. Even if the comprehensive quality of grafted seedlings is very high and the price is cheap, he still stubbornly believes that seedlings are good.

Therefore, seedlings and grafted seedlings each have their own advantages, specifically according to their own actual situation to choose.

Is it better to have sweet-scented osmanthus original or grafted?

Native ones can grow taller and grow up, suitable for planting in the courtyard, and do not blossom until three or four years. Grafting has good shape and fast growth, strong disease resistance and cold resistance, can basically achieve flowering in the same year, and the plant is low, so it is suitable for potted plants in the north house.

Grafting propagation

Grafting propagation is the best in spring, sweet-scented osmanthus seedlings, privet or water wax can be used as rootstocks, and the survival rate of abdominal grafting is high. It is appropriate to transplant in spring and autumn, big seedlings need to bring soil balls, apply sufficient base fertilizer, choose areas with plenty of sunshine, and avoid transplanting in winter. The types of grafting are distinguished by scions, which can be divided into branch grafting and bud grafting, and branch grafting can be divided into hard branch grafting and tender branch grafting. For example, according to the cutting and combination methods of rootstock and scion, the cutting technology of rose can be divided into cutting, splitting, leaning, budding, ventral grafting and so on. According to the period of grafting, it can be divided into growing period and dormant period. Generally, branch grafting can be carried out 2-3 weeks before bud germination in spring, that is, in the first and middle of March. It can also be carried out from mid-October to early December. After grafting, the scion and rootstock first heal, and then the scion sprouts and shoots in the following year. For leaning grafting and tender branch grafting, it is appropriate to choose May-June. Budding is usually carried out from July to August. Practice has proved that the survival rate of ventral grafting is the highest, and ventral grafting is also called rhizosphere grafting, which is a branch grafting method without cutting the crown of rootstock. Its specific operation is to cut the scion into small segments, then cut 1 knife (about 2 cm long), and the reverse side is cut into a small slope, the cutting method is the same as cutting. After digging and pruning, the rootstock is cut 1 knife in the smooth and straight part of the rhizome, which is as deep as xylem, so that it is suitable for scion insertion. Insert the scion into the rootstock, aim at the cambium, quickly fasten the binding site with a plastic belt, bag and replant.
