How to fertilize citrus? When is the right time to fertilize citrus? What fertilizer is best for citrus

There are many varieties of citrus, and each variety has a relatively large market demand in our country. Citrus is now grown to a certain extent in various regions of our country, and as market demand expands, more and more people are growing it. When growing citrus, fertilization work is very important, and there are many points we need to pay attention to when fertilizing. Below, the editor brings you the precautions for fertilizing citrus. Let's take a look!

Fertilization periods for citrus

  1. For 1- to 2-year-old young trees, focus on cultivating each flush of branches and shoots, and follow the principle of applying light fertilizer frequently and applying more before and after shoot growth.

  2. For trees that have just begun bearing fruit (3-4 years old), apply heavy fertilizer in winter, before spring, and before autumn.

  3. For mature bearing trees, fertilize 4-5 times a year, mainly with three applications: before and after fruit harvest, before spring shoots, and before autumn shoots.

1. Types of fertilizer

When fertilizing, the choice of fertilizer is very important. Appropriately increasing the proportion of organic fertilizer applied can effectively improve the growth capacity and yield of citrus. Therefore, when fertilizing, we should increase the proportion of organic fertilizer applied to about 65%. Control the fertilization time according to the age of the fruit trees. For adult bearing trees, half is applied during the flowering and fruiting stage and the expansion stage, with about 4 applications per year. It should mainly be concentrated in spring and autumn. Pay attention to the timing of spring fertilization; in the south it is usually done around mid-February. The main purpose is to increase the number of flowers and promote the growth of spring shoots, with nitrogen fertilizer as the main type and phosphorus and potassium fertilizers as supplements.

2. Fertilizer dosage

The control of fertilizer dosage is relatively strict. For some new citrus orchards, many growers have not paid attention to the input of fertilizer. This leads to poor growth capacity of citrus, insufficient yield, and affects planting benefits. When fertilizing, we must pay attention to scientific fertilization. Control the amount of fertilizer well. Too little fertilizer will reduce citrus yield, while too much can easily cause excessive vegetative growth of citrus trees and lead to fertilizer burn and other adverse phenomena. We should control the dosage according to the age of the fruit trees. For adult trees, control the amount of compound fertilizer at about 3 kg, with a nitrogen fertilizer ratio of 2/3. For middle-aged and young trees, it depends on the specific situation.

3. Nutrient ratio

During the growth of citrus, attention should be paid to controlling the nutrient ratio well. Citrus has certain requirements for trace elements. Therefore, when fertilizing, we should pay attention to appropriately adding trace elements to supplement the nutritional needs required for citrus growth. Then pay attention to comprehensive and thorough fertilization, and control the ratio of nitrogen, phosphorus, and potassium fertilizers well. The amount of nitrogen fertilizer applied must never be too much, to avoid causing fertilizer burn, and it will also affect the absorption of other nutrient elements by citrus. This seriously reduces the growth capacity of citrus trees. Finally, according to the soil fertility and structure, appropriately supplement the lacking trace elements.

4. Chemical fertilizer application

Although appropriately applying chemical fertilizer can promote the growth of citrus, attention must also be paid to the dosage, otherwise it will harm the citrus trees. Moreover, for some young trees it may even cause death. In addition, when applying chemical fertilizer, it must not be applied dry; it should be applied in combination with water. When applying chemical fertilizer, it is best to dilute it in water and then apply it in furrows. This can not only reduce the harm of chemical fertilizer to citrus, but also reduce environmental pollution. It promotes soil absorption of fertilizer and ensures the healthy growth of citrus trees.

The above is a brief introduction to the precautions for fertilizing citrus. Although fertilizing citrus trees is very important, it cannot be done blindly, otherwise the harm to citrus will be very great. That is all for today's introduction.
