Agricultural grade magnesium chloride fertilizer quality standard:
Magnesium Chloride Hexahydrate
Total alkali metal chloride (NaCl) %≦
Vegetable long-term application of magnesium fertilizer can improve crop yield and character. Magnesium is mainly present in chlorophyll, vegetative and pectin, and plays an important role in photosynthesis. Magnesium ion is a variety of enzyme activator, promote in vivo carbohydrate conversion and metabolism, promote fat and protein synthesis. Oil crops can increase the oil content of magnesium, magnesium can also promote crop absorption of silicon. Magnesium deficiency magnesium fertilizer, can improve its oil content, magnesium can also promote crop absorption of silicon. Magnesium fertilizer magnesium fertilizer, can improve the effect of phosphate fertilizer.
When the plant is magnesium, its outstanding performance is the chlorophyll content decreased, and the emergence of loss of green disease. As the mobility of magnesium in the phloem strong, magnesium symptoms are often first manifested in the old leaves, and gradually developed to the new leaves. In the case of magnesium deficiency, plants are short and slow to grow. Dicotyledonous plants lack of phosphorus when the leaves between the green, and gradually from light green to yellow or white, there will be different sizes of brown or purple spots or stripes; severe magnesium deficiency, the whole leaves necrosis. Gramineous plants lack of magnesium, the leaf base of chlorophyll accumulation of dark green spots, the rest was pale yellow; severe magnesium deficiency, the leaves fade and stripes, especially in the tip of the necrotic spots appear.
