Problems solved by technology

In order to further improve the effect of humic acid-containing water-soluble fertilizers, manufacturers often add a variety of plant growth regulators to them. As a low-toxic pesticide, plant hormones are still controversial in the academic circles about the harm to humans and the environment caused by their abuse.

Abstract

The invention provides a water-soluble fertilizer rich in boron element, containing humic acid and special for strawberries. The water-soluble fertilizer is prepared from the following raw materials in parts by weight: humic acid substances, calcium superphosphate, double superphosphate, potassium sulfate, urea, ammonium sulfate, boric acid, indole potassium butyrate, sodium naphthalene acetate, trace elements, a penetrating solvent, esterified vegetable oil and an accelerated solvent. A specific preparation method comprises the following steps of mixing the raw materials, and then mixing by a high-speed shearing mixer to obtain pulp; filtering particle impurities by a vibration filter and then enabling a mixture to overflow to a granulating spray nozzle; uniformly spraying the mixture into spherical droplets under the action of a rotary shearing centrifugal force of the spray nozzle, wherein the droplets slowly fall in a tower, are subjected to heat exchange with ascending air current in the tower and then are cooled to 45 to 65DEG C, thus obtaining water-soluble fertilizer particles. The water-soluble fertilizer provided by the invention has the advantages of excellently-remarkable production-income increasing effect, good water solubility and high utilization rate; soil is improved, and the yield and the quality of crops are improved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special water-soluble fertilizer containing humic acid for strawberries and a production method thereof. Background technique [0002] Compared with traditional compound fertilizers, water-soluble fertilizers have obvious advantages. They are easier to be absorbed by crops, and their absorption and utilization rate is relatively high. More importantly, they can be applied to agricultural facilities such as sprinkler irrigation and drip irrigation to realize the simultaneous application of water and fertilizer. Water belt fertilizer, water and fertilizer integration, to achieve the efficiency of saving water, fertilizer and labor. Its effective absorption rate is more than double that of ordinary chemical fertilizers, reaching 80% to 90%. It can improve fertilizer utilization rate, save agricultural water, and reduce ecological environment. Pollution, improvement of crop quality and r...
