Spraying potassium formate foliar fertilizer can improve grape quality
Spraying potassium fertilizer outside grape roots, according to plant growth and soil potassium fertilizer situation, advocate low concentration, multiple spraying, both positive and negative leaves should be sprayed evenly. Potassium is closely related to many metabolic processes in plants, such as photosynthesis, respiration and synthesis of carbohydrates, fats and proteins. Potassium formate foliar fertilizer can promote the activation of enzymes. It has the advantages of high potassium content, high solubility, easy absorption, safety and harmlessness. It can spray potassium formate foliar fertilizer to improve the quality of grape fruit. Potassium was absorbed and utilized by plants in ionic form. The root system of grape began to absorb potassium three weeks after germination, and the absorption rate increased gradually. The absorption peak was from flowering to turning-color period, which accounted for 50% of the total annual absorption fruit, and then the absorption rate d
