How to fertilize oranges? When is the right time to apply fertilizer for citrus? what's the best fertilizer for citrus?

There are many varieties of citrus, and all kinds of varieties have a 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 planting. Fertilization is very important when growing oranges, and there are a lot of things we need to pay attention to when applying fertilizer. The following editor brings you some points for attention on citrus fertilization. Let's take a look!

Fertilization period of citrus

   1-year-old and 1-year-old 2-year-old young trees should focus on the cultivation of branches and shoots, and fertilization should be based on the principle of applying thin fertilizer to Corydalis and applying more fertilizer in front and back of shoots.

   2. The first fruit trees (3-4 years old) were re-applied in winter, before spring and before autumn.

   3. The mature fruit trees are fertilized 4-5 times a year, mainly before and after fruit harvest, before spring shoot and before autumn shoot.

1. Types of fertilization

The choice of fertilizer is very important when applying fertilizer. Properly increasing the application proportion of organic fertilizer can effectively improve the growth ability and yield of citrus. So we should increase the proportion of organic fertilizer to about 65% when we are applying fertilizer. The fertilization time should be controlled according to the forest of the fruit tree. half of the adult fruit trees are carried out in the flowering and fruit stage and expansion period, applying fertilizer about 4 times a year. Mainly focus on spring and autumn, pay attention to the time of fertilization in spring, usually around the middle of February in the south. Mainly in order to increase the number of flowers and promote the growth of spring shoots, fertilizer is mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer.

2. Fertilizer consumption

Fertilizer consumption control is relatively strict, for some new citrus orchards, many farmers do not pay attention to the use of fertilizer. As a result, the growth ability of citrus is poor, the yield is insufficient, and the planting benefit is affected. We must pay attention to scientific fertilization when applying fertilizer. Control the amount of fertilizer, too little fertilizer will reduce the yield of citrus, too high and easy to lead to excessive growth of citrus trees, causing fertilizer damage and other bad phenomena. We should control the dosage according to the age of fruit trees, the amount of compound fertilizer should be controlled at about 3 kg for adult trees, and the proportion of nitrogen fertilizer should be 2% and 3% for adult trees. Middle-aged and young trees depend on the specific conditions.

3. Nutrition proportion

In the process of citrus growth, attention should be paid to controlling the proportion of nutrients. Citrus has certain requirements for trace elements. Therefore, we should pay attention to the appropriate addition of trace elements when applying fertilizer to supplement the nutritional needs of citrus growth. Then we should pay attention to comprehensive and thorough fertilization, control the proportion of nitrogen, phosphorus and potassium fertilizer, nitrogen fertilizer application should not be too much, avoid causing fertilizer damage, but also affect the citrus absorption of other nutrient elements. Seriously reduce the growth ability of citrus trees. Finally, the lack of trace elements should be properly supplemented according to the fertility and structure of the soil.

4. Application of chemical fertilizer

Although proper application of chemical fertilizer can promote the growth of citrus, we should also pay attention to the amount of chemical fertilizer, otherwise it will cause harm to citrus trees. And for some young trees, it may also lead to death. And in the application of chemical fertilizer must not be dry application, should be combined with water application. In the application of chemical fertilizer, it is best to dilute it in water, and then ditch application, which can not only reduce the harm of chemical fertilizer to citrus, but also reduce environmental pollution. Promote soil absorption of fertilizer to ensure the healthy growth of citrus trees.

The above is a brief introduction of citrus fertilization points for attention, although citrus fertilization is very important, but it can not be carried out blindly, otherwise the harm to citrus is very great. That's all for today's introduction. This article is for reference only. I hope it can help you all.
