How is the leaf of the rich tree white to return a responsibility? What are the ways to save it?

The rich tree is a perennial evergreen tree, erect, palmately compound leaves open like umbrellas, round crown, green branches and green leaves, which is very suitable for landscaping. As an ornamental bonsai, its novel shape caters to the modern mentality of beautifying the home environment in homes, hotels, shopping malls, hotels and office buildings, and is deeply loved by consumers. But in the process of breeding, the leaves may turn white, so how is the leaf whitening of the rich tree? What are the ways to save it?

First, what is the whitening of the leaves of the rich tree?

The most likely leaf whitening of a rich tree is "lack of manganese" or "excessive manganese". Let's take a specific look at it below.

1. The importance of "manganese" to the wealth tree.

Manganese is one of the micronutrient elements necessary to maintain the normal growth of plants. Deficiency and excess will affect the normal growth of crops. Manganese is the catalyst of many enzymes in plants, which can promote the reduction of nitric acid, improve the utilization of nitrogen, is conducive to protein synthesis, and is related to chloroplast synthesis, can improve crop photosynthesis, play the effect of disease resistance and yield increase.

2. The relationship between the content of manganese and the whitening of the leaves of rich trees.

Serious lack of manganese or excessive manganese will inhibit root elongation, affect the absorption of nutrient elements, hinder the synthesis of chloroplast protein, reduce the content of chlorophyll, and disrupt the supply of hormones in the plant. thus affecting the normal growth of the plant, resulting in the whitening of the leaves of the rich tree, and death in serious cases.

It is worth noting that this is a process from quantitative change to qualitative change, that is to say, the leaves of the rich tree will not suddenly turn white, but will go through a process of yellowing. Therefore, when there are symptoms, it is easy to mistakenly think that it is caused by the disease for prevention and treatment, the treatment effect is very little, and sometimes there will be the phenomenon of spread and aggravation.

Second, what are the salvage measures for the white leaves of the rich tree?

So when the leaves of the rich tree turn white, how to save it?

1. Determine the cause

When the rich tree has the symptom of leaf whitening, it is necessary to carefully determine whether the cause is lack of manganese or excessive manganese. The rhizome of the plant can be examined. If there are no symptoms of disease, it can be suspected to be the problem of manganese content. The cause of leaf whitening and the degree of poisoning should be determined by testing the manganese content in the plant and soil.

2. Improve the soil

The plant can only absorb available manganese from the soil, and its content is related to the types and conditions of the soil. Therefore, the content of exchangeable manganese should be reduced or increased. In addition, alkaline substances such as lime or fertilizer can be applied to the highly acidic soil to increase the pH value of the soil to more than 5. at the same time, the drainage system should be deeply dug in low-lying waterlogged land to improve soil permeability.

3. Drug treatment

For plants that have shown symptoms of leaf whitening, about 0.3% ferrous sulfate solution can be sprayed 1-2 times, or 0.2% calcium nitrate solution can be sprayed to reduce the symptoms of leaf whitening of poisoned rich trees.
