What is the latest manifestation of iron deficiency in peach trees

Peach trees are cultivated all over our country, and peach is a kind of fruit that many people like to eat very much. When we plant peach trees and fertilize, we should pay attention to supplement adequate and comprehensive nutrition. Especially iron and other trace elements, if the peach tree iron deficiency, then there will be iron deficiency, affecting the growth of peach trees. So what is the manifestation of iron deficiency in peach trees? How to prevent and cure it? The following editor will give you a brief introduction, let's have a look!

1. Symptom manifestation

After the occurrence of iron deficiency in peach trees, the mesophyll will gradually fade and yellowing, but there is not much change on both sides of the veins, resulting in a strong green net on the leaf surface and loss of green. And with the aggravation of the disease, the chlorosis of the leaves will be aggravated, resulting in the whole leaf becoming white. The leaf edge will gradually wither and scorch, and there will be serious defoliation. If iron deficiency is serious, the top of the new tip of the peach tree will also die. The fruit color of diseased trees cannot be colored, and because iron is difficult to transfer in fruit trees. Therefore, the performance of iron deficiency usually starts from the young leaves at the top of the shoot.

2. Occurrence conditions

Under normal circumstances, the iron content of the soil in the orchard is relatively sufficient. However, if the soil orchard is saline-alkaline, then the soluble bivalent iron in the soil will gradually be converted into insoluble trivalent iron. Peach trees can not be absorbed and utilized at all, resulting in iron deficiency symptoms. Therefore, the factors leading to soil salinization may be the cause of iron deficiency in peach trees. In addition, when the soil is too dry, the above-ground water will be concentrated on the surface of the soil when it evaporates. In addition, heavy soil viscosity, poor drainage and irrigation are easy to cause iron deficiency in peach trees.

3. Prevention and control methods

Improving soil and increasing iron content in soil are the key measures to prevent and control iron deficiency in peach trees. We can add an appropriate amount of soluble iron to the soil, which can effectively treat iron deficiency peach trees. Then the content of organic matter in soil can be increased and the physical and chemical properties of soil can be improved by applying organic fertilizer and planting green manure. The phenomenon of peach yellow leaves can be effectively reduced by digging ditches to drain water, reducing the water level of groundwater and improving soil permeability to treat the problem of soil over-alkali. For iron-deficient diseased trees, we can supplement them with soluble iron in various ways.

It is mainly based on prevention. We should spray an appropriate amount of ferrous sulfate to the branches before peach trees germinate to control iron deficiency in a short time. It can also be applied in the soil with appropriate amount of chelated iron, which can obviously treat yellow leaf disease. Then before the fruit tree germinates, we can cut the side root of the peach tree and soak it with ferrous sulfate. Or inject ferrous sulfate or ferric citrate into the trunk. However, if the injection method is improper, it is so easy to cause drug damage, so we should pay more attention to it.

The above is a brief introduction to the manifestation of iron deficiency in peach trees. That's all for today's introduction. This article is for reference only. I hope it can help you all.
