The efficacy of magnesium in plant and the symptoms of magnesium deficiency

release time:2021-05-27


Magnesium is one of the main components of chlorophyll in plants and  related to the photosynthesis of plants. Magnesium is also the activator of ribulose diphosphate carboxylase, which can promote the assimilation of carbon dioxide by plants. Magnesium ions can stimulate the activities of glucokinase, fructokinase and phosphogluconutase related to carbohydrate metabolism; it is also an activator of DNA polymerase and can promote DNA synthesis.

Magnesium is also related to fat metabolism and can promote the conversion of acetic acid into acetyl-CoA, thereby accelerating the synthesis of fatty acids. Magnesium deficiency in plants hinders metabolism in the body, which has a particularly great impact on the development of young tissues and the maturation of seeds.

Our company regularly organizes special lectures to promote company culture and popularize product knowledge in order to provide customers with better services.

On April 22, 2021, the topic will explain the role of magnesium in plants and the symptoms of magnesium deficiency and the role of magnesium fertilizer.


Symptoms of magnesium deficiency

Magnesium is easy to move in plants, and plant magnesium deficiency is first manifested on old leaves in the middle and lower parts. In dicot plants, it shows chlorosis between veins, and gradually changes from light green to yellow or white, and brown or purple-red spots of different sizes will appear, but the veins remain green, and premature senescence and shedding of leaves appear in severe cases.

Gramineae plants appear as dark green spots at the base of the leaves, and light yellow in the rest. When severe magnesium deficiency, the leaves fade and streak, and necrotic spots appear on the tip of the leaf. The symptoms of magnesium deficiency in crops tend to occur when the fruits or storage organs are enlarged. Magnesium will transfer to the fruit during the fruit ripening process, the old leaves and the leaves near the fruit will turn yellow first, and the symptoms will be obvious.


The effect of using magnesium fertilizer

Improve crop agronomic traits

Increase crop yield

For example, the application of magnesium fertilizer can increase the dry matter accumulation of corn to a certain extent, promote the growth and development of day lily, increase the single-grain weight and vertical diameter of Kyoho grape winter fruit, promote the growth of cabbage, and promote the increase of rice tillers, thereby increasing crop yields. .

Improve crop quality

Reasonable application of magnesium fertilizer can help improve the quality of fruits and vegetables, including common apples, peaches, grapes, etc., as well as various vegetables.


How to use magnesium fertilizer

Base fertilizer: Magnesium fertilizer should be applied as a base fertilizer, mixed with compound fertilizer, organic fertilizer or applied separately.

Spray: Water-soluble magnesium fertilizers are generally applied on the surface. Foliar spraying of magnesium fertilizer is a commonly used effective measure to remedy crop magnesium deficiency.
