Potassium chloride is a kind of quick acting potassium fertilizer with high solubility
Potassium chloride is a chemically neutral and physiologically acidic quick acting potassium fertilizer. Potassium chloride is suitable for field crops such as rice, wheat, cotton, corn and sorghum; It is also suitable for neutral calcareous soil. Potassium chloride can mainly supplement the potassium element of plants. Among the three elements of nitrogen, phosphorus and potassium, potassium can not only promote the stiffness and strength of plant flowering and fruiting and branch and leaf growth, but also improve the disease resistance of plants.
Effect of potassium chloride on plant growth
1.The application of potassium fertilizer can promote the photosynthesis of crops, promote crop fruit and improve the cold resistance and disease resistance of crops, so as to improve agricultural yield. Potassium exists in the form of free potassium ion in plants, which can promote the metabolism of carbohydrate and nitrogen; Control and regulate the activity of various mineral nutrient elements; Activation of various enzymes; Control the transport of nutrients and water; Maintain the internal pressure of cells to prevent plant wilting.
2.Potassium chloride promotes the activation of enzymes. The activation of enzymes is one of the most important functions of potassium in the process of plant growth. It has been found that potassium is an activator of more than 60 enzymes. Therefore. Potassium is closely related to many metabolic processes in plants, such as photosynthesis, respiration and the synthesis of carbohydrates, fats and proteins
3.Potassium chloride promotes photosynthesis and the transport of photosynthetic products ① improves photosynthetic efficiency; ② Adjust the opening and closing of air holes and control the inlet and outlet of CO2 and water; ③ Promote the synthesis of carbohydrates and accelerate the flow of photosynthetic products.
4. Potassium chloride promotes protein synthesis ① promotes the uptake and operation of NO₃, a key component of protein synthesis; ② It is closely related to the process of protein synthesis.
5.Potassium chlorideenhances plant stress resistance
Potassium could reduce soluble amino acids and monosaccharides, increase cellulose and thicken cell wall; Potassium accumulation in crop roots produces osmotic pressure gradient, which can enhance water absorption; Potassium can close the stomata of crop leaves to prevent water loss. Therefore, potassium can enhance the disease resistance, cold resistance, drought resistance, lodging resistance and salt resistance of crops.
6.Potassium chloride improves the quality of crop products, increases the protein content of grain crops, the crude fat and palmitic acid content of oil crops, and the starch and sugar content of potato and sugar crops; Increase the fiber length, strength and fineness of fiber crops and cotton; Adjust the sugar acid ratio of fruit and increase its vitaminC content; Improve the shape, size, color and flavor of fruits and vegetables and enhance their storage resistance.
