What is the best way to grow navel orange seedlings in southern Jiangxi?

Gannan navel orange is world-famous for its large and regular fruit, strong orange fragrance, sweet and juicy taste. It is rich in vitamins and carotene and is very nutritious. Every spring and autumn is the season for planting Gannan navel orange. So what is the best way to plant Gannan navel orange seedlings ? Let’s take a look below.

1. High-quality seedlings

Navel orange seedlings in nurseries on the market are generally divided into one-year seedlings and two-year seedlings, and the two-year seedlings are stronger. When selecting seedlings, we should pay attention to choosing seedlings that grow well and are strong. Such seedlings have stronger disease resistance and higher survival rate, and can ensure yield and quality.

2. Land preparation and tillage

The soil in the orchard should be plowed and leveled. If the soil is compacted, the tillage depth can be appropriately increased. Then mix the base fertilizer with the soil thoroughly to allow the soil to absorb enough nutrients. After the orchard has been plowed for half a month, cuttings can be carried out. When transplanting, pay attention to the spacing between plants and rows, and control the planting density. Generally speaking, 4 meters × 5 meters or 3 meters × 5 meters are appropriate for flat land, and 3 meters × 3.5 meters or 3 meters × 3 meters are appropriate for mountainous land. Be careful not to damage the roots of the seedlings when cutting, otherwise it will make it difficult for the seedlings to absorb nutrients and affect the survival rate. Cover the soil immediately after the cuttings are completed and water them to help them take root.

3. Clearing seedlings and weeding

3-4 weeks after the navel orange seedlings are planted, the weak and diseased seedlings should be removed in time according to the growth of the seedlings, and good seedlings should be replaced. This work should be carried out throughout the entire growth period of the navel orange seedlings, and the seedlings should be checked and cleared in a timely manner. Since the seedlings' ability to absorb nutrients is relatively weak, the weeds in the orchard must be cleared in a timely manner to prevent the weeds from robbing nutrients, which will not only affect the growth and development of the seedlings, but also waste fertilizer .

4. Fertilizer and water management

During the growth process of Gannan navel orange, the demand for fertilizer, nutrients and water is very large, especially fertilizer. In addition to applying sufficient base fertilizer when plowing the orchard in the second step, it is also necessary to apply fertilizer and topdressing in time according to the growth of the navel orange trees to ensure that the navel orange has sufficient and comprehensive nutrients for its growth during the growth process. As for watering, it depends on the moisture of the orchard soil. Maintain the moisture of the soil. It is important to note that during the peak growing season of navel oranges, more watering is required to promote flowering and fruiting and increase yield.

5. Tree management

For Gannan navel orange trees with larger crowns, timely pruning is required to prevent the crown from being too dense and affecting the quality of the fruit. When pruning, remove weak branches, overlapping branches and useless branches to maintain the shape and ventilation of the tree. At the same time, the main trunk should be ring-cut in winter to promote flowering and increase fruit yield in the next year.

6. Pest and disease control

The disease and pest control of navel oranges in southern Jiangxi needs to follow the principles of prevention first and integrated control. During the planting process, the trees should be kept strong and their resistance should be improved. At the same time, a combination of biological and chemical control methods should be adopted, and pesticides should be sprayed in time to prevent the occurrence of diseases and pests.
