Citrus Fertilization Precautions and Correct Methods
There are many varieties of citrus, and all kinds have a relatively large market demand in China. Citrus is now grown to some extent in various parts of China, 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 to pay attention to when fertilizing. Below, the editor brings you the precautions for citrus fertilization. Let's take a look!
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, fertilization is generally carried out during the flowering and fruiting stage and the expansion stage, about 4 times a year. It should mainly be concentrated in spring and autumn. Pay attention to the timing of spring fertilization, which in the south is usually carried out around mid-February. The main purpose is to increase the number of flowers and promote the growth of spring shoots. The fertilizer should be mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer.
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 and insufficient yield of citrus, affecting planting benefits. When fertilizing, we must pay attention to scientific fertilization. Control the fertilizer dosage well. Too little fertilizer will reduce the yield of citrus, while too much can easily cause excessive vegetative growth of citrus trees, triggering fertilizer damage 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 trees 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, control the ratio of nitrogen, phosphorus, and potassium fertilizers well. The amount of nitrogen fertilizer applied must never be too much, to avoid fertilizer damage, and it will also affect the absorption of other nutrient elements by citrus. This seriously reduces the growth capacity of citrus trees. Finally, appropriately supplement the lacking trace elements according to the soil fertility situation and structure.
4. Chemical Fertilizer Application
Although appropriate application of chemical fertilizer can promote the growth of citrus, attention should also be paid to the dosage, otherwise it will cause harm to citrus trees. And for some young trees, it may even lead to death. Moreover, 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. Promote soil absorption of fertilizer and ensure the healthy growth of citrus trees.
The above is a brief introduction to the precautions for citrus fertilization. Although fertilization of citrus trees is very important, it must not be done blindly, otherwise the harm to citrus will be very great. That's all for today's introduction.
