Uses of boric acid in agriculture and knowledge provided by manufacturers

1. Product features 1. High efficiency: This product has stable boron effect and high fertilizer efficiency. After adding an appropriate amount of penetrant and adsorbent, the boron content is ≥15%, which is 1.5 times the content of borax. Applying 100 grams of this product per mu is equivalent to applying 0.5-1.0 kg of borax. 2. Instant dissolving: This product dissolves very quickly at low temperature, while borax dissolves very slowly. It needs to be completely dissolved in hot water at 60-90 °C, and a small amount of precipitation will be precipitated when the temperature is lowered. When preparing borax solution, it must be dissolved in hot water at 60-90°C, stirred until there is no precipitation, and then diluted with water to the desired solution, and the prepared solution must be used immediately, otherwise boron crystals will be precipitated, affecting Fertilizer spraying, the precipitated boron can even cause local toxicity to crops. In addition, this product has high solubility, its solubility in water temperature 30 ℃ is equivalent to the solubility of borax in 75 ℃ hot water. Therefore, compared with borax, this product has the outstanding advantages of rapid dissolution, high solubility, and convenient preparation and use. 3. Economy: This product is added with appropriate amount of adsorbent and penetrant, which saves the dosage. After application, it can be quickly absorbed by leaves, stems, flowers, fruits, and soil, and the utilization rate of boron is as high as 80%. This product is especially suitable for the operation of large-scale agricultural machinery, and can be used in conjunction with other measures to simplify the operation technology and save labor and cost. 4. Safety: This product is absorbed in the season when it is used, there is no residue in the soil, and no pollution is caused. It meets the requirements of environmental protection and the development direction of pollution-free agriculture, and has broad prospects for use. 5. Neutrality: The aqueous solution of this product is close to neutral (pH 7.6), and it will not degrade when mixed with various pesticides, and it is also a good insecticide, disease prevention, antiseptic disinfectant.

2. How to use this product 1. Foliar spraying: 50-100 grams per mu, or spraying concentration of 0.2-0.3%, spray 1- 2 times; 2. Base and top dressing: 100-200 grams per mu, mixed with other chemical fertilizers or organic fertilizers and applied to the soil. 3. Matters needing attention: 1. Boron is an essential trace element in the process of plant growth and development. Therefore, a reasonable amount should be paid attention to in the use process to achieve the purpose of increasing yield and improving quality. Otherwise, boron damage will also occur; 2. Different plants have different sensitivities to boron. Dicotyledonous plants need more boron than monocotyledonous plants, and gramineous crops need less boron. Therefore, when using this product, it should be considered to be applied to highly and moderately sensitive plants (A, highly sensitive plants). : Rape, alfalfa, cauliflower, celery, clover, beet, apple, grape, radish, cabbage, sunflower, lettuce, etc.; B. Moderately sensitive: cotton, tomato, potato, tobacco, carrot, peanut, peach, pear, chestnut, tea, etc.). 3. The flowering period is the critical period when plants need boron. It is more economical to use foliar spray when using this product. 4. Due to the difference in the abundance and deficiency of boron in the soil, the variety and type of various crops and the inconsistency of the selected fertilization methods and measures, it can lead to different effects of increasing yield in agricultural production.
