Why are citrus prone to trace element deficiencies? Citrus root system is developed, deep and widely distributed, once colonized, that is, fixed in a position for a long time, the root system continues to selectively absorb certain nutrients from the root domain, which requires the strength and capacity of soil supply nutrients, once the supply is unbalanced, it is easy to cause the deficit of certain nutrients. Citrus is more sensitive to deficiencies and overdose of many elements, so the emergence of vegetarian deficiency is more common, especially newly developed orchards are planted on thin soil. Therefore, it is necessary to apply fertilizer rich in various nutrients according to the nutritional characteristics of the orchard soil. To ensure the physiological balance of fruit tree nutrition. Or deep soil turning combined with soil modification measures to make the soil layer deep, loose texture, suitable pH, good ventilation.
How do you feel that grapefruit, gong citrus, and orange are more serious than Magnesium Oxide price magnesium deficiency in sugar oranges? Indeed, one is that they have large fruits, consume more, and the results are more, such as 1 orange tree can easily reach more than 100 pounds, and sugar oranges are afraid that it is somewhat difficult. In addition, there is also a point that varieties with multi-core fruits are more likely to be deficient in magnesium than varieties with few or no seeds. Because magnesium is required for seed formation, multi-nucleated varieties require more magnesium than non-nucleated/less-nucleated varieties. For example, the leaves of Sha tin grapefruit, grapefruit, gong citrus, and orange are often prone to magnesium deficiency symptoms. In addition to the more magnesium demand than the seedless, even phosphate fertilizer will be more.

Why is magnesium deficiency so severe in autumn and winter? Magnesium deficiency, from June fruit into Magnesium Nitrate Fertilizer the expansion period after the decline of the largest amplitude, and there is no effective supplement in the middle, or the amount is not enough, the entire expansion period (June-October) needs a huge amount of magnesium, after the expansion period, almost consume all the magnesium of the old leaves, naturally now will be very serious. The larger the fruit, the greater the demand for magnesium, due to the large demand, so we generally supplement magnesium in advance to prevent magnesium deficiency, and once citrus has symptoms of magnesium deficiency, if you want to recover, it is not a fertilizer application that can be made up immediately. Now entering September, calcium and magnesium can be supplemented. Magnesium is an essential element for citrus photosynthesis. Magnesium is one of the essential nutrients for plant growth and development, is the only metal element of the chlorophyll molecule, involved in the composition of chlorophyll, pigment, involved in the synthesis of proteins, nucleic acids and fats, when magnesium is sufficient, the fruit surface of citrus, the leaf surface wax is thick, the fruit oil cell is full, and the color is good. The demand for magnesium during the expansion of the fruit is very high. During the expansion period and branch growth period Magnesium Oxide powder of the fruit, the physiological activity is very active and requires a large amount of magnesium.
