What are the appearance characteristics of robust flower seedlings, cuttings and grafted seedlings?
Grafting seedlings are a technical means to use wild seedlings belonging to the same family as rootstocks, collect branches of high-yield and high-quality varieties to be planted and graft them on rootstocks, and use the developed roots of wild rootstocks to absorb enough nutrients for grafted varieties, so as to achieve the goal of high yield and high quality.
Grafting methods are divided into branch grafting and bud grafting.
superiority
Grafted seedlings can enhance the disease resistance and low temperature tolerance of plants, help overcome the harm of continuous cropping, increase yield and maintain the excellent characters of parent trees as much as possible. Grafted seedlings consist of rootstocks and scions. Rootstocks are generally seedlings with good adaptability, and scions are generally varieties with high ornamental or economic value. This kind of grafting not only has good resistance, but also can produce high economic benefits. It is mostly used for some woody flowers with high ornamental value, such as Japanese late cherry, peony, plum blossom and peach blossom.
disadvantaged
Grafted seedlings will inevitably produce rejection because of the fusion of two genes, which shows two extremes: overgrowth and withering and yellowing. Therefore, it needs superb cultivation techniques to control and it is possible to obtain high yield.
The healing place is easy to be blown off by the wind, and its life span will be shorter than that of seedlings.
Seedling plant
Seedling raising is a cultivation method, which collects high-yield and high-quality fruit and vegetable seeds, takes them out in the shade, sows them in seedbeds or fields after corresponding growth cycles, germinates and grows to a certain size, and then transplants them to the fields for planting.
The stand formed by seedlings can cultivate large-diameter timber. Seedling cultivation conforms to the natural growth and development law of trees, and the root system is complete. Under the scientific seedling raising technical measures, the seedlings grow neatly and healthily.
Seedling raising can obtain more plants in a small area in a short time, with simple method and low cost, which is suitable for large-scale specialized production.
It is the most important seedling raising method in plant cultivation, and in hybrid breeding, it is also necessary to use the characteristics of offspring separation of hybrid seedlings to select new varieties, which is an important means of hybrid breeding.
superiority
General seedlings have the characteristics of developed root system, strong vitality, great plasticity and long life. Because its root system is developed, as long as the land has enough nutrients, the seedlings can stretch freely, that is, how deep the roots are, how high the tree is. No technical content is needed. The seedling propagation method is simple and easy, the production cost is low, the fruit seedlings take root, the growth potential is strong and the adaptability is strong.
disadvantaged
The life span of seedling fruit trees is long, but the initial fruit period is too long, and the fruit tree characters are quite different. It takes more than ten years for seedlings to enter the high-yield period, and the high-yield period is more than thirty years or even hundreds of years (depending on the genes of seedlings). Now this method is basically not used to cultivate fruit seedlings in production, unless it is used as fruit rootstock.
Cutting seedling
Cutting seedling is a new plant which is a part of stem, root or leaf cut from a plant and inserted into a suitable substrate for propagation.
superiority
Cutting seedlings can retain the excellent characteristics of the mother plant, generally do not mutate, and the seedlings are neat and consistent. The seedling raising method is relatively simple, low in cost, quick in seedling formation and early in flowering and fruiting; Sufficient propagation materials and high seedling yield; Reproduction is easy, and this method is often used for flowers that are not easy to bear seeds and are easy to take root by cutting. Many flowering shrubs and ground cover plants are propagated by cutting. Such as crape myrtle, hibiscus, hydrangea, heather, Ligustrum lucidum, rose, pentagram and so on.
disadvantaged
Cutting seedlings have no main roots, their life span is shorter than that of seedlings and grafted seedlings, their growth potential is unreal, and they are prone to degradation and crown deviation.
As far as the propagation mode is concerned, there is not much difference between these seedlings. All need to be done manually. Generally speaking, the two are comparable. Therefore, if you want to breed, you can choose according to your past experience.
