The method of spraying a fertilizer solution to make plants obtain nutrients through leaves is called foliar fertilization. A fertilizer that directly applies the nutrients required by a crop to the leaves is called foliar fertilizer. Foliar fertilization can make nutrients from the leaves directly into the body, participate in the metabolism of crops and the synthesis of organic matter, so it is faster and more effective than soil fertilization. Compared with root soil fertilization, foliar fertilization has many advantages Fast nutrient absorption, good fertilizer effect Can promptly and effectively correct crop deficiency Increase crop yield and improve crop quality Convenient fertilization, not affected by crop growth period Enhance crop resistance and prevent plant diseases and insect pests Although it is good to reduce the pollution of soil and water resources, foliar fertilizer can only give full play to the role of foliar fertilizer in increasing yield and income only by applying foliar fertilizer technology properly. Notes on foliar fertilization The concentration should be appropriate The concentration of foliar fertilization is directly related to the effect of spraying. If the concentration of the solution is too high, it is easy to burn the leaves of the crop after spraying. The concentration of the solution is too low, which increases the workload and fails to meet the requirements of supplementing crop nutrition. Therefore, in the application, due to different fertilizers and crops, it should be formulated according to local conditions. The effect of foliar fertilization is directly related to temperature, humidity, and wind. For foliar spraying, it is best to choose no wind, cloudy or humid, and less evaporation before 9 am. The most suitable is After 4 pm, if it rains 3 to 4 hours after spraying, make up spray. Master the spraying period When foliar fertilization, according to the requirements of different growth and development stages of various crops for nutrient elements, the crops should be sprayed when the nutrient elements require the most and are most urgent to achieve the best results. The root has a larger and more complete absorption system than the leaves, and it has a large demand for nutrients such as nitrogen, phosphorus, and potassium. Therefore, more than 10 foliar fertilizers are required to reach the total amount of nutrients absorbed by the roots. Foliar fertilization cannot completely replace crop root fertilization, and must be combined with root fertilization. Spray the right area The leaves and stems of the upper, middle, and lower parts of the plant have different metabolic abilities, and their ability to absorb external nutrients varies greatly. Therefore, it is necessary to choose an appropriate spraying site. Disclaimer: Some articles on this website are transferred from the Internet.
