Requirements and precautions of soil planting in citrus orchard

At present, many citrus varieties have been listed one after another. It is estimated that in a short time, a large number of citrus varieties will be listed, and there are many varieties, large and small. But today, let's talk about the planting requirements of citrus orchard soil and see if your citrus orchard meets the requirements.

1. Soil pH value

At present, citrus cultivation in China is mainly distributed in red soil, and the PH value of red soil is generally acidic.

The pH of soil is closely related to the decomposition of organic matter in soil, the transformation of fertilizer and the availability of trace elements.

However, the PH value should not be too low. If the PH value of soil is lower than 4, it will inhibit the growth of root system and even lead to the death of trees. The optimum PH value for citrus growth is about 5.

2. Soil fertility

Soil fertility is the key to the normal growth of citrus, and the content of nitrogen, phosphorus and potassium fertilizer in the soil will directly affect the yield and fruit quality of citrus.

In order to achieve high yield of citrus, we should not only ensure that there are enough nitrogen, phosphorus and potassium elements.

The ratio of nitrogen to potassium should be properly increased, so the content of nitrogen, phosphorus and potassium in soil can be used as a reference for the application amount of nitrogen, phosphorus and potassium fertilizer.

3. Thickness of soil layer

The depth of soil layer has great influence on the root distribution of citrus.

If the soil layer is deep enough, the root system of citrus is strong, developed and widely distributed.

It can improve the absorption area of nutrients and water by citrus trees and promote the healthy growth of citrus trees.

Enhance the cold resistance and drought resistance of trees. Too shallow soil layer will inhibit the extension of roots, with shallow distribution and small area.

It is easily influenced by external environmental factors such as temperature.

The potential yield of trees will be seriously affected, so the depth of soil layer should be controlled at about one meter.

4. Soil permeability

Citrus is a fruit tree with fungal roots. Only by ensuring good air permeability can citrus trees grow normally.

Soil with good air permeability is very beneficial to the growth of seedling roots and the activity of soil microorganisms.

If the soil is too sticky, it will inhibit the growth of mycorrhiza and the reproduction of microorganisms.

But also lead to soil hypoxia, produce all kinds of toxic substances, inhibit root respiration, lead to root development blocked, root rot.

In a word, it is some planting requirements for citrus orchard soil. Of course, if the soil is good, citrus fruit trees are more likely to yield high, so there are many details that can not be ignored in the planting process.

These are the requirements for citrus soil cultivation. Welcome to read other agricultural contents of Qinggua.com.
