Magnesium is a component of the chlorophyll molecule. Indispensable The metallic element is related to the composition of chlorophyll pigment; magnesium deficiency can cause citrus leaves to exhibit... Lost Green. In Of plants Magnesium requirements during the young fruit stage Even more Urgent Required If you don't pay attention to supplementing magnesium, Very It can easily cause yellowing of functional leaves, affecting fruit enlargement and the development of later-stage quality. So, Magnesium nitrate, used as a highly effective magnesium-supplementing fertilizer in agriculture, is widely applied in various agricultural production practices.

Magnesium deficiency in fruit trees the symptoms Mainly old leaves. 、 V-shaped yellowing of the leaves—when severe, only the base of the leaf remains green; sometimes, as the leaf veins thicken, the leaves turn yellow. This is a combined deficiency of magnesium and boron. Symptom The probability is very high. Many fruit growers increase potassium fertilizer after fruit enlargement, but they overlook... Use Magnesium nitrate for agricultural use, and the like. Supplementation of trace and minor elements can exacerbate deficiencies in magnesium and boron due to antagonistic interactions among the elements.

Calcium and magnesium are the two most heavily demanded mineral elements in fruit trees, following nitrogen, phosphorus, and potassium. As a chemical element belonging to the same group as calcium, magnesium shares many similar chemical properties with calcium; consequently, there is inevitably competition between the two for absorption.
The young fruit stage is the golden period for calcium uptake in fruit trees. Calcium can effectively promote fruit enlargement and reduce the occurrence of various physiological disorders such as fruit cracking and sunburn. Therefore, many fruit farmers... Most people won't overlook it. Supplement. But If you simply supplement with calcium fertilizer, magnesium absorption will be affected. will do Suppressed, By application Magnesium nitrate fertilizer for agricultural use Only by keeping the calcium-to-magnesium ratio within an effective range can both be taken into account.

In addition, Magnesium deficiency also affects fruit quality. Unused Magnesium nitrate for agricultural use leads to After magnesium deficiency ， Chlorophyll levels decrease, leaves turn yellow, photosynthesis weakens, protein synthesis is inhibited, starch production declines, and the transport of organic products to the growing points is impaired, leading to smaller fruits, lower sweetness, and uneven coloration. The activity of magnesium can activate many enzymes involved in elemental activation and signal transduction. ， It has an affinity for the abundant macroelements remaining in the soil and can be reabsorbed and utilized by plants, thereby helping to balance calcium—a relatively inert element. 。

Magnesium and potassium have both antagonistic and synergistic effects. of the Effect ， Relationship Compare Complex. When the potassium ion concentration in the soil is too high, the cation competition effect can impair magnesium’s availability. At low potassium levels, even small amounts of magnesium can enhance the plant’s uptake of potassium. But Magnesium deficiency in actual production Crop damage caused by The situation is than Potassium deficiency Also be strict. Heavy ， Therefore, when applying potassium fertilizer to fruit trees during the fruit-expansion stage, it is essential to do so in conjunction with... Magnesium nitrate for agricultural use Fatty, to prevent magnesium deficiency Lead to Worsening.
