Poor management of navel orange during planting can cause many problems, of which fallen leaves are one kind. Although the leaves are not as serious as the fruit, the leaves will affect the photosynthesis of the navel orange, reduce the nutrient accumulation of the fruit, and cause the sugar content of the fruit to decrease and the quality to decrease. There are even times when it affects the rate of flowering of navel oranges, the fruit is reduced, and the yield is insufficient. So what should I do with the navel orange leaves? Let’s take a look at it with Xiaobian!
1. Protect the roots
The root is the most important part of the growth of the navel orange tree, and the root of the navel orange tree is very sensitive to environmental changes. Root growth is affected, nutrient absorption and transportation are blocked, leading to defoliation. Therefore, we must do a good job of protecting the roots. For example, when fertilizing, we cannot let the roots touch the roots directly. It is also not possible to use unfertilized farmyard manure, and pay attention to the depth when ploughing the soil to prevent damage to the roots.
2, foliar fertilizer
Appropriate topdressing should be based on the growth of navel orange during the planting process, and attention should be paid to the application of foliar fertilizer. Many friends just don't pay attention to foliar fertilizer, which leads to too little nutrients in the leaves and defoliation. And the leaves are also the place where the tree body is manufactured and stored for nutrition. Appropriate spraying of the foliar fertilizer can also improve the flowering result rate and carry out the work of preserving flowers and fruits. Foliar fertilizer spraying should not be less than three times during the entire growth period of navel orange.
3, reasonable watering
When the navel orange tree sprouts in spring, the demand for water is not very large. We must control the amount of watering, the soil water content should not be too much, and should not exceed 65%, so that the soil can be kept slightly dry. Such a water content not only promotes the flower bud differentiation of the navel orange tree, but also prevents the leaves from falling due to less water. However, when encountering high temperature and drought, it is necessary to water it in time. In the rainy season, it is also necessary to do drainage work.
4, proper pruning
Navel orange has a large tree shape and many branches and leaves. If it is not trimmed in time, it will easily affect the light absorption of the inner and lower middle leaves. Insufficient illumination will also cause leaves. Therefore, we must promptly cut off branches of old branches, long branches and other branches, and retain strong branches. It is also necessary to cut off the branches that are not flowering, and leave strong branches before the bud period, and the mother branches with the guilt. Increase production while reducing leaf loss.
5, timely topdressing
Above are measures to prevent defoliation. Topdressing is a remedy after defoliation, because the vitality of the roots after umbilical orange leaves is degraded, affecting the absorption capacity. At this time, we should promptly topdress the fertilizer, restore the growth of the navel orange tree, and promote nutrient absorption. Follow the principle of a small amount of multiple application when topdressing, usually in the navel orange bud period and two physiological fruiting period. Fertilizer can use decomposed farmyard manure, and control the amount of topdressing fertilizer according to the age of the navel orange and the number of fruit.
The above is a brief introduction to how to do the navel orange leaves. The navel orange leaves are more common, but too many leaves represent abnormal. Therefore, if you find a large number of umbilical orange leaves, you must check the cause of the fallen leaves in time, and then prescribe the right medicine, you can not blindly deal with it, otherwise it will only be self-defeating.
