The latest course of field management techniques and methods of navel orange

Navel orange is a kind of popular orange variety in our country, there are many people planting navel orange, the market of navel orange is relatively large, and the market is relatively high among similar varieties. So now the planting area of navel orange is getting wider and wider, and more and more people are planting it, but the management of planting navel orange is very important. So how to manage navel orange planting in the field? Today, the editor brought the field management technology of navel orange. Let's have a look!

1. Weeding in time

In the process of planting navel orange, the number of weeds in the orchard should be observed regularly, and the malignant weeds such as bamboo leaf grass and Bidens bipinnata should be removed in time. Because the nutrient absorption capacity of some weeds is very strong, if it is not pulled out in time, it will not only increase the planting cost, but also affect the growth and development of navel orange. And when weeding, we should pay attention to clean the roots, because the growth of weeds is very tenacious, as long as there is a certain opportunity, it will sprout and grow again. The method of weeding can use chemical weeding or artificial weeding. Pay attention to the concentration of herbicides during chemical weeding to prevent the inhibition of navel oranges.

2. Shaping and pruning

Navel orange trees belong to the category of big trees, which have strong growth ability and luxuriant branches and leaves, so it is necessary to do a good job in shaping and pruning fruit trees. Improve the permeability of the orchard, prevent it from being too closed, affect the fruit of the inner chamber and the middle and lower parts of the fruit tree, and reduce the yield. The specific pruning method should be determined according to the age of the tree, for example, when the young tree is young, it should be trimmed lightly, and the method of coring and sprouting should be used to promote the growth of branches. The fruit trees should cut off the overlong and dense branches to improve the flowering and pollination rate of fruit trees, increase the yield and expand the economic benefits of planting.

3. Reasonable fruit protection

There are a large number of physiological fruit drops in navel oranges every summer. Normally, navel oranges have two physiological fruit drops in the whole growth period. The first time after the flowers withered, the second time around mid-June. The main reason for fruit drop is due to the high nutritional competitiveness of fruit trees and the lack of nutrition. Moderate fruit drop is beneficial to the growth of fruit trees, but if too much will affect the yield of fruit trees. Therefore, in order to avoid falling too much fruit, we should do a good job in fruit protection, properly spray foliar fertilizer according to the specific conditions of fruit trees, wipe off summer shoots in time, and prevent summer shoots from grabbing fruit nutrition.

4. Timely harvest

The harvest time of navel orange also has certain requirements, mainly according to the direction of harvest. For example, if you want to store the navel orange fruit after harvest, the progress should be about 90% before the coloring of the navel orange fruit is completed, and it is most suitable to pick the fruit when the fruit is not softened. Early harvest is not conducive to fruit ripening, harvest should be listed immediately after late harvest, because it is not conducive to storage. Two weeks before harvest, the application of fertilizer and water should be controlled, chemical fertilizer should be stopped, and watering should be changed to small water drip irrigation. Harvesting should not be carried out in rainy days, and there should be certain picking techniques, and the picking methods will affect the later fruit storage.

The above is a brief introduction to the field management technology of navel orange. the field management of navel orange is directly linked to yield and fruit quality, so we must strengthen management when planting. And there is also a more important point is the prevention and control of diseases and insect pests, the harm of diseases and insect pests is very great, we must do a good job in prevention and control work, want to know navel orange specific what are more common diseases and insect pests, you can visit our website to view previous articles!
