The method of applying fertilizer solution to the plant to obtain nutrient elements through the leaves is called foliar fertilization. For the purpose of absorbing the foliage, the nutrient required by the crop is directly applied to the foliar fertilizer, which is called foliar fertilizer. Foliar fertilization allows nutrients to enter the body directly from the leaves, participate in the metabolism of the crop and the synthesis of organic matter, and is therefore more rapid and effective than soil fertilization. Compared with root soil fertilization, there are many advantages of foliar fertilization Nutrient absorption, good fertilizer effect Can timely correct crop deficiency syndrome Increase crop yields and improve crop quality Easy to fertilize, not affected by crop growth period Strengthen crop resistance, prevent and treat pests and diseases Reducing the pollution of soil and water resources The foliar fertilizer is good, but only the correct application of foliar fertilization technology can give full play to the role of foliar fertilizer in increasing production and income. Foliar fertilization precautions The concentration should be suitable The foliar fertilization concentration is directly related to the spraying effect. If the solution concentration is too high, the crop leaves may burn after spraying. If the solution concentration is too low, the workload will increase, and the nutritional requirements of the supplementary crop will not be met. Therefore, due to fertilizer, because of different crops in the application, according to local conditions and symptomatic preparation. The effect of foliar fertilization is directly related to temperature, humidity, wind force, etc. It is best to choose foliar spraying to be done before 9 o'clock in the morning without wind, cloudy or high humidity and low evaporation. After 4:00 pm, if it rains after 3-4 hours after spraying, additional spraying is required. Master the spraying period Foliar fertilization, according to the different growth and development stages of various crops on the demand for nutrient elements, select the crop nutrient needs the most and most urgent spraying, in order to achieve the best results. The roots have a larger and more complete absorption system than the leaves, and there is a large demand for nutrient elements such as nitrogen, phosphorus, and potassium. Therefore, more than 10 times of foliar fertilizers are required to achieve the total amount of nutrients absorbed by the roots. Foliar fertilization cannot completely replace the roots of crops and must be combined with root fertilization. Spraying suitable parts The upper, middle, and lower leaves and stems of the plant are different in their ability to absorb external nutrients due to their different metabolic activities. Therefore, appropriate spray sites should be selected.
