Detailed Explanation of Key Technical Points for Navel Orange Field Management
Navel orange is a relatively popular orange variety in China, and many people grow navel oranges. The market for navel oranges is also relatively large, and the market price is relatively high among similar varieties. So now the planting area of navel oranges 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 cultivation of navel oranges, the number of weeds in the orchard should be observed regularly, and malignant weeds such as bamboo-leaf grass and beggar's ticks should be pulled out in time. Because some weeds have a very strong ability to absorb nutrients, if they are not pulled out in time, it will not only increase planting costs, but also affect the growth and development of navel oranges. And when weeding, care should be taken to remove the roots completely, because weeds grow very tenaciously and will sprout and grow again as long as there is any opportunity. 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 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 work of shaping and pruning the fruit trees must be done well. Improve the ventilation and light penetration of the orchard to prevent it from being too closed, which would affect fruiting in the inner canopy and middle-lower parts of the fruit trees and reduce yield. The specific pruning method should be determined according to tree age. For example, in the young tree stage, pruning should be light, using methods such as pinching and bud removal to promote branch growth. For fruiting trees, excessively long and dense branches should be cut off to increase the flowering and pollination rate of the fruit trees, increase yield, and expand the economic benefits of planting.
3. Reasonable fruit retention
Every summer, navel oranges experience a large amount of physiological fruit drop. Normally, navel oranges will have two periods of physiological fruit drop throughout their growth period. The first is after the flowers fall, and the second is around mid-June. The main reason for fruit drop is that the fruit trees have relatively strong nutritional competition and lack 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 should do a good job in fruit retention for the fruit trees, appropriately spray foliar fertilizer according to the specific condition of the fruit trees, and promptly remove summer shoots to prevent summer shoots from competing for the fruit's nutrients.
4. Timely harvesting
The harvesting time of navel oranges also has certain requirements, mainly determined according to the harvesting purpose. For example, if the fruit is to be stored after harvesting, then it is most suitable to pick when the navel orange fruit coloring is not yet complete, at about 90% progress, and when the fruit has not softened. Harvesting too early is not conducive to fruit ripening, and harvesting too late means it must be marketed immediately, because it is not conducive to storage. Two weeks before harvesting, the application of fertilizer and water 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 certain picking techniques, because the picking method will affect later fruit storage.
The above is a brief introduction to navel orange field management techniques. Field management of navel oranges is directly linked to yield and fruit quality, so everyone must strengthen management when planting. And one more important point is pest and disease control. The harm of pests and diseases is very great, so prevention and control work must be done well.
