Magnesium sulphate heptahydrate is a kind of double nutrient high-quality fertilizer
Agricultural magnesium sulfate heptahydrate is a component of chlorophyll and pigment and a metal element in chlorophyll molecules. Magnesium can promote photosynthesis and promote the formation of carbohydrates, proteins and fats. Magnesium is the activator of hundreds of enzymes. It also participates in the composition of some enzymes and promotes the metabolism in crops. Agricultural magnesium sulfate heptahydrate can improve the disease resistance of crops and prevent the invasion of bacteria. Agricultural magnesium sulfate heptahydrate can also promote the formation of vitamin A and vitamin C in crops, so as to improve the quality of fruits, vegetables and other crops. Sulfur is the synthesis of amino acids, proteins, cellulose and enzymes in crops. At the same time, the application of agricultural magnesium sulfate heptahydrate can also promote the absorption of silicon and phosphorus by crops. In agriculture, magnesium sulfate heptahydrate is a double nutrient high-quality fertilizer (containing Mg and s). Sulfur and magnesium are medium elements of crops and the fifth and sixth nutrient elements of crops. It can not only increase the yield of crops, but also improve the taste of fruits; Magnesium sulfate heptahydrate is used as a supplement, additive and activator of magnesium in animal feed processing in agriculture. It plays an important role in material metabolism and nerve function of livestock and poultry, so as to make livestock and poultry healthy and strong. The role of magnesium sulfate heptahydrate in aquaculture in the field of agriculture is conducive to the growth of positive bacteria and make aquaculture more fruitful. Magnesium sulfate heptahydrate, as a fertilizer in agriculture, can be directly used as base fertilizer, topdressing and foliar fertilizer. It can be applied alone or mixed as a component, which can be applied in the fields of agriculture, high value-added precision agriculture, flowers and soilless cultivation. The dosage and usage are as follows:
1. Dosage and usage of magnesium sulfate heptahydrate as base fertilizer:
Before cultivated land, magnesium sulfate heptahydrate can be mixed with other fertilizers or organic fertilizers and applied to the soil. Generally, about 10 kg of agricultural magnesium sulfate is used per mu.
2. Dosage and usage of magnesium sulfate heptahydrate as topdressing
The top dressing with magnesium sulfate heptahydrate needs to be applied in advance, which can be applied in ditch or mixed with water. Generally, 10-13kg magnesium sulfate is suitable for each mu of land, and 250-500g magnesium sulfate can be applied for each fruit tree; After applying enough magnesium fertilizer, it can be applied every few crops, and it is not necessary to apply it every season.
3.Dosage and usage of magnesium sulfate heptahydrate as foliar spray:
In order to correct the symptoms of crop magnesium deficiency, magnesium sulfate heptahydrate can be used for extra root topdressing, but the fertilizer effect of foliar spraying is not lasting. In order to achieve the effect, it should be sprayed several times continuously. Foliar spraying of magnesium sulfate can be carried out in the early and middle stages of crop growth; The spraying concentration of magnesium sulfate varies with the growth period of different crops. Generally, the spraying concentration of magnesium sulfate on the leaves is: 0.5% – 1.0% for fruit trees, 0.2% – 0.5% for vegetables, 0.3% – 0.8% for rice, cotton and corn. Generally, the application amount of magnesium fertilizer solution per mu is about 50-150 kg.
4.Agricultural magnesium sulfate heptahydrate should not be used too much:
Magnesium sulfate heptahydrate fertilizer belongs to trace element fertilizer, which should not be used too much in agriculture. If it is mixed with liquid fertilizer, the concentration generally does not exceed 0.5 g/:L; If solid fertilizer is used, 1500 kg magnesium sulfate mixed in farm fertilizer is also about 50kg per mu. If the amount of magnesium sulfate heptahydrate is too large, it will affect the normal growth of plants and fruit quality.
