The Latest Tutorial on Field Management Techniques for Navel Oranges
The navel orange is a relatively popular orange variety in China, and many people grow navel oranges. The market for navel oranges is also fairly large, and the market price is relatively high among similar varieties. So now the navel orange planting area is becoming wider and wider, and more and more people are growing them, but management is very important when growing navel oranges. So how should field management be carried out when growing navel oranges? Today the editor brings you the field management techniques for navel oranges. Let's take a look!
1. Timely weeding
During the navel orange growing process, the amount of weeds in the orchard should be observed regularly, and noxious weeds such as bamboo-leaf grass and beggarticks should be pulled out in time. This is because some weeds have a very strong ability to absorb nutrients. If they are not pulled out in time, they will not only raise planting costs but also affect the growth and development of navel oranges. When weeding, be careful to remove the roots completely, because weeds grow very tenaciously and will sprout and grow again as long as they have the slightest chance. Weeding methods can use chemical weeding or manual weeding. When using chemical weeding, pay attention to the concentration of the herbicide to prevent it from also inhibiting the navel oranges.
2. Shaping and pruning
Navel orange trees belong to the large-tree category, with strong tree growth and luxuriant branches and leaves. Precisely because of this, the shaping and pruning work on the fruit trees must be done well. Improve the orchard's air and light permeability and prevent it from being too closed off, which would affect fruiting in the inner and middle-lower parts of the fruit trees and reduce yield. The specific pruning method depends on tree age. For example, during the young tree stage, prune lightly, using methods such as pinching and bud removal to promote branch growth. For fruiting trees, cut off overly long and overly dense branches to increase the flowering and pollination rate of the fruit trees, increase yield, and expand planting economic benefits.
3. Reasonable fruit preservation
Every summer, navel oranges show a large amount of physiological fruit drop. Normally, navel oranges have two periods of physiological fruit drop throughout their entire growth period. The first is after the flowers fall, and the second is around mid-June. The main reason for fruit drop is the relatively strong nutrient competition among the fruit trees and a lack of nutrients. A moderate amount of fruit drop is beneficial to the growth of the fruit trees, but if there is too much, it will affect the yield of the fruit trees. Therefore, in order to avoid excessive fruit drop, we must do a good job in preserving the fruit of the trees. According to the specific condition of the fruit trees, appropriately spray foliar fertilizer and promptly remove summer shoots to prevent the summer shoots from robbing the fruit of nutrients.
4. Timely harvesting
The harvesting time of navel oranges also has certain requirements, mainly depending on the harvesting purpose. For example, if the fruit is to be stored after harvest, then it is most suitable to pick when the navel orange fruit coloring has not yet been completed, at about 90% progress, and when the fruit has not softened. If harvested too early, it is not conducive to fruit ripening; if harvested too late, it must be brought to market immediately, because it is not conducive to storage. Two weeks before harvest, fertilizer and water application should be controlled, chemical fertilizer application should be stopped, and watering should also be changed to small-drip irrigation. Harvesting should not be carried out on rainy days, and there must be a certain harvesting technique, because the harvesting method will affect later fruit storage.
The above is a brief introduction to the field management techniques for navel oranges. Field management of navel oranges is directly linked to yield and fruit quality, so everyone must strengthen management when growing them. There is also one more important point, which is pest and disease control. The harm from pests and diseases is very great, so control work must be done well.
