The latest soil requirements for citrus planting
Citrus is a kind of fruit in autumn in China, and its market demand is very large. Now there are a lot of people who grow citrus. Before we plant citrus, the choice of soil is very important, which directly affects the normal growth and development of citrus. It has a lot to do with the yield and quality of citrus. So how to choose the soil to grow oranges? The following editor brings you the soil requirements for citrus planting. Let's have a look!
1. Soil pH
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, the transformation of fertilizer and the availability of trace elements in soil. However, the PH value should not be too low, if the soil PH value is less than 4, it will inhibit root growth, and in serious cases, it will lead to tree death, and the most suitable PH value for citrus growth is about 5.
2. Soil fertility
Soil fertility is the key to the normal growth of citrus. The content of nitrogen, phosphorus and potassium in soil will directly affect the yield and fruit quality of citrus. If you want a high yield of citrus, you should not only ensure that there is sufficient nitrogen, phosphorus and potassium. Among them, the proportion of nitrogen, phosphorus and potassium should be increased appropriately, so the content of nitrogen, phosphorus and potassium in soil can be used as a reference for the application of nitrogen, phosphorus and potassium fertilizer.
3. Thickness of soil layer
The depth of soil layer has a great influence on the distribution of citrus roots. If the soil layer is deep enough, the citrus root system has strong growth ability, developed and widely distributed. It can increase the absorption area of nutrients and water and promote the robust growth of citrus trees. Enhance the cold and drought resistance of the tree, and if the soil layer is too shallow, it will inhibit the extension of the root system, shallow distribution and small area. It is easily affected by external environmental factors, such as temperature, etc. The yield of trees will be seriously affected, so the depth of the soil should be controlled at about one meter.
4. Soil permeability
Citrus is a kind of fruit tree with fungal root system, and it is necessary to ensure good permeability in order to make citrus trees grow normally. The soil with good permeability is very beneficial to the growth of seedling roots and the activity of soil microorganisms. If the soil is too sticky, on the contrary, it will inhibit the growth of mycorrhiza and the reproduction of microorganisms. Moreover, it will also lead to anoxia in the soil, produce a variety of toxic substances, inhibit root respiration, hinder root development, root rot and other phenomena.
The above is a brief introduction to the soil requirements for citrus cultivation. In addition to the above, we should also pay attention to the soil texture to ensure that all aspects of the soil can ensure the normal growth of citrus. This is the end of today's introduction, this article is for reference only, I hope it can be helpful to everyone!
