Fertilization Techniques for Navel Orange

Navel orange is what we call sweet orange, it is a kind of orange, the planting time in our country is not very long compared with many other common fruits. The most famous navel orange in China is Gannan navel orange, which is mainly because Gannan navel orange is suitable for planting navel orange. Gannan navel orange has the characteristics of large fruit, sweet, beautiful, juicy quality and so on. Well, what we are going to learn today is a very important point in the planting process of navel oranges. Let's take a look at its fertilization techniques.

Fertilization for young trees

Navel oranges usually bear fruit in five years, so we usually call navel oranges in the first four years young trees. These four years are the period of growth and development of navel orange trees, what we need to do is to promote the growth of young trees. We fertilize the annual navel orange trees about a month after planting, and we need to apply fertilizer once a month, mainly urea. When the treetops sprout and mature, we need to cooperate with the use of compound fertilizer, the dosage is controlled at about 50 grams, and the application is carried out in the extra-root trench. It is also important to note that young trees during the growing period are topdressing about eight to nine times a year, which means they can stop topdressing at the beginning of October. On the other hand, the fertilization method of navel orange trees from two to four years old is basically the same as that of one year old, but the amount of fertilization can be increased appropriately, but no more than two hundred grams at most.

II. Fertilization for fruiting trees

1. Spring fertilizer

The spring fertilizing of navel oranges should be carried out as soon as possible, usually between February and March every year. When applying fertilizer, we mainly use the way of external furrow application, so as to avoid nutrient damage to the root system of navel orange. The main purpose of spring fertilizer is to promote the growth of spring buds, which has a lot to do with the fruiting branches, and has a great influence on the subsequent results. We mainly use ternary compound fertilizer for fertilization, in which the content of nitrogen is relatively high, and the dosage of each fruit tree is about one jin to two jin.

2. Flower and fruit fertilizer

The flower and fruit fertilizer of navel orange can be divided into pre-anthesis fertilizer, fruit protection fertilizer and strong fruit fertilizer. Generally speaking, pre-flowering fertilizer is applied at the beginning of April, which is to supplement the nutrition of the tree and ensure the quality of flowering, mainly quick-acting fertilizer. Navel orange is a stable fruit fertilizer, which is usually carried out at the end of April or with compound fertilizer, the amount of each plant is controlled at about half a jin, and it can be carried out in combination with fruit protectant when topdressing, which can improve the fruit setting rate of navel orange and reduce fruit drop. Finally, there is strong fruit fertilizer, which is generally carried out during the period from the end of June to early July, and the amount of fertilizer is controlled at about two jin, mainly potash fertilizer, and should be combined with the use of boron fertilizer and zinc fertilizer.

3. Fertilizer after fruit harvest

After the navel orange is harvested, in order to restore the tree potential and ensure the production in the coming year, then we need to fertilize the fruit scientifically. Under certain conditions, it is best to use the combination of organic fertilizer and inorganic fertilizer, which can not only supplement the nutrition of the tree, but also improve the differentiation of flower buds, make navel orange trees survive the winter safely and ensure the yield in the coming year.

This is probably the general fertilization situation in navel orange planting. If you want to know more about the amount of fertilization or the details of fertilization, please leave a message for consultation with the editor. Because the editor manager is limited, I won't give you details here.
