What are the precautions for fertilizing citrus? A detailed explanation of the latest key points
There are many varieties of citrus, and all kinds of varieties have a relatively large market demand in our country. Citrus now has a certain planting area in all parts of our country, and with the expansion of market demand, more and more people are growing it. When growing citrus, fertilization work is very important, and there are still 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 together!
1. Types of fertilizer
When fertilizing, the choice of fertilizer is very important. Appropriately increasing the application ratio of organic fertilizer can effectively improve the growth capacity and yield of citrus. Therefore, when fertilizing, we should increase the application ratio of organic fertilizer 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 fertilization about 4 times a year. It should mainly be concentrated in spring and autumn. Pay attention to the fertilization time in spring, 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 amount
The control of fertilizer amount 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 the yield of citrus, while too much can easily cause excessive vegetative growth of citrus trees and lead to undesirable phenomena such as fertilizer damage. We should control the amount well according to the age of the fruit trees. For adult trees, control the amount of compound fertilizer at about 3 kg, with nitrogen fertilizer accounting for 2/3, while 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, and never apply too much nitrogen fertilizer, so as 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, according to the soil fertility situation and structure, appropriately supplement the lacking trace elements.
4. Application of chemical fertilizers
Although appropriately applying chemical fertilizers can promote the growth of citrus, attention should also be paid to the amount, otherwise it will cause harm to citrus trees. Moreover, for some young trees, it may even lead to death. In addition, when applying chemical fertilizers, they must not be applied dry; they should be applied in combination with water. When applying chemical fertilizers, it is best to dilute them in water and then apply them in furrows. In this way, it can not only reduce the harm of chemical fertilizers to citrus, but also reduce environmental pollution. Promote the soil's absorption of fertilizer and ensure 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.
