Foliar fertilizer special for tomatoes

Abstract

The invention relates to a foliar fertilizer special for tomatoes. The foliar fertilizer special for tomatoes contains not less than 80% of humic acid (by HA dry basis), not less than 10% of K2O, and not more than 15% of H2O in percentage by weight, wherein the pH value is 8-11. The foliar fertilizer special for tomatoes is in the shape of a black sheet or a powder; the diluted foliar fertilizer can be brown sauce-shaped liquid, and the effective concentration is reduced with the increment of diluting factor. The foliar fertilizer for tomatoes has the advantages of saving the production cost, increasing the yield and realizing simple and convenient use method.

Description

technical field [0001] The invention relates to a foliar fertilizer, in particular to a special foliar fertilizer for tomato. Background technique [0002] In recent years, foliar fertilizers have developed rapidly in the agricultural material market, especially potassium dihydrogen phosphate foliar fertilizers have been favored by farmers, but the real potassium dihydrogen phosphate fertilizers have high sales prices and high input costs. And after being put into use, there is no significant luxuriant effect and cannot be widely used. New potassium dihydrogen phosphate, improved potassium dihydrogen phosphate, high-efficiency potassium hydrogen phosphate and other fertilizers mostly borrow the reputation of potassium dihydrogen phosphate. Foliar fertilizers with magnesium sulfate as the main raw material are popular because of their low sales price, luxuriant foliage after use, and quick results. resulting in a decrease in the number of crops. [0003] Humic acid and humi...

Problems solved by technology

However, these fertilizers have a common feature, most of them add a certain amount of ammonium nitrogen, potassium chloride, magnesium sulfate, ferrous sulfate and phosphorus, boron, calcium, zinc, molybdenum, copper and other elements to humic acid. The salt content forms the so-called Dabu pills, which increases the content of nutrients and the cost of fertilizer processing, but the more the better, the purpose of prescribing the right medicine and balancing fertilization cannot be achieved

[0004] Using simple fulvic acid or potassium humate as fertilizer can not only improve the soil, fertilize the soil, but also stimulate the physiological metabolism of crops and promote the growth and development of crops. However, using fulvic acid or potassium humate, although the cost is not too high High, easy for farmers to accept, but because the concentration is not easy to control during the application process, it is easy to cause the leaves to scorch or turn over due to excessive concentration of humic acid, it is difficult to achieve the ideal application effect, use a lower concentration of fulvic acid or humic acid Potassium has a certain effect, but because too much water is added and the content of active ingredients is too low, farmers always feel unreliable, unreliable, and untrustworthy, and different concentration ranges also have different production-increasing effects. In what concentration range should it be applied? The effect is the best, which can save production costs to the greatest extent, increase output and benefit, and these are the problems that need to be solved by existing technologies
