Magnesium fertilizers generally refer to fertilizers containing magnesium, which can provide magnesium to the soil. The more common magnesium fertilizers include magnesium sulfate, magnesium chloride, magnesium carbonate, magnesium nitrate, magnesium oxide, and magnesium oxyphosphate fertilizers.
Magnesium is a component of plant chlorophyll and phytophyll, and the only metal element in chlorophyll molecules. Magnesium plays an important role in photosynthesis. Magnesium ion is an activator of various enzymes, which promotes the transformation and metabolism of sugar in crops, and promotes the synthesis of fat and protein.
Magnesium can also promote the absorption of silicon and phosphorus by crops, thereby improving crop disease resistance. Magnesium can also promote the formation of vitamin A and vitamin C in crops, thereby improving the quality of fruits, vegetables and other crops.
Magnesium fertilizer can be directly used as base fertilizer, top dressing and foliar fertilizer. For example, calcium magnesium phosphate fertilizer and magnesium ammonium magnesium phosphate slightly soluble in water can be used as base fertilizer, and the application amount can be calculated according to the magnesium content. Generally, the magnesium content per mu is 1-1.5 kg.
For example, magnesium oxide and magnesium sulfate can be used as topdressing fertilizers for crops. Topdressing fertilizers using magnesium fertilizers must be applied early, and can be applied in furrows or mixed with water. Generally, 10-13 kg of magnesium sulfate is suitable for each mu of land, and 250-500 grams of magnesium sulfate can be applied for each fruit tree. After enough magnesium fertilizer is applied, it can be applied every few crops, and it is not necessary to apply it every season.
For example, magnesium nitrate can be used for foliar spraying of crops, mainly for the magnesium deficiency symptoms caused by root disorders in fruit trees, solanaceous fruits, vegetables and legume vegetables. The commonly used magnesium nitrate content is 1%, because foliar spraying The fertilizer effect is not long-lasting. In order to achieve the effect, it should be sprayed several times in a row.
