How to Choose Jackfruit Saplings? A Detailed Guide to the Latest Selection Methods
Jackfruit is a tropical fruit that is very similar to durian, but the differences between them are also significant, and it is also the heaviest fruit in the world. Jackfruit has extremely high nutritional value. At present, the main producing areas of jackfruit in China are Guangdong, Hainan, Guangxi, Fujian, Yunnan and other places, but the yield is not very high, so the market price is still quite attractive. So when planting jackfruit, how should we choose jackfruit saplings? Let's take a look at today's sharing from the editor.
1. Seedling grown from seed
A seedling grown from seed is a type of jackfruit sapling cultivated directly from jackfruit seeds. Its variety is very pure and also very high quality, all of which has been screened and confirmed by relevant professional institutions. Even so, it cannot be ruled out that some of them are unsuitable for planting, and among naturally fine varieties there will also be more excellent saplings. We generally select seedlings with intact nutrient bags, complete nutrient soil, a soil ball diameter greater than twelve cm, a height greater than twenty cm, that are robust, vigorous in growth, well developed in root system, and free of pests, diseases, and external damage. The most suitable seedling age for planting seedlings grown from seed is about three to six months; too short or too long will affect the survival rate of planting.
2. Grafted seedlings
Another type of jackfruit sapling is the grafted seedling. At present, grafted seedlings are widely used in planting, and most planting seedlings are cultivated through grafting. When choosing grafted seedlings, the first thing we observe is whether the nutrient bag of the grafted seedling is intact and whether the nutrients are complete. Next, choose saplings with a nutrient soil ball diameter greater than twelve cm and a height greater than twenty cm. In fact, this is similar to the selection method for seedlings grown from seed. But we should note that the height of the grafted seedling should preferably be more than thirty cm, and the thickness of the rootstock section should also be considered, generally greater than one cm, and the seedling age of the planting stock should preferably be about six to nine months.
3. Layered seedlings
In fact, many plants can be grown by layering, such as osmanthus trees and citrus trees. Layered seedlings are also called air-layered seedlings, and this is a propagation method using asexual reproduction. The first thing we should note is whether the latex of the layered seedling has been removed; if it has not, then the success rate of planting is very low. Moreover, layered seedlings are relatively short in plant height, but at the same time their yield is not high and their resistance is weak. In fact, layered seedlings are rarely used at present. But if you really want to choose them, try to choose one-year-old seedlings that are free of pests and diseases, relatively robust, and have a relatively developed root system.
The main methods for cultivating jackfruit saplings are seed propagation, grafting propagation, and layering propagation. However, among these three propagation methods, the most commonly used at present is grafting propagation. In this way, the planting cost is lower and the growth speed is faster, and to a large extent its purity is not much different from seed propagation. That is all for today's sharing from the editor, but the editor still recommends that when choosing planting stock, you should also take into account the local climate and planting environment.
