Problems solved by technology

How to get out of the predicament, the general organic fertilizer is applied to the compacted soil, due to the "deficiency disease" and "bacteria deficiency disease", the organic fertilizer cannot be fully decomposed and transformed into low fertilizer efficiency
It is an indisputable fact that crops grown on compacted soil rely on the escort of chemical pesticides. Microbial active bacterial fertilizers will become powerless in the face of chemical pesticides

Abstract

The invention provides a preparation method of a high-activity humic acid containing water-soluble liquid fertilizer. The high-activity humic acid containing water-soluble liquid fertilizer is mainlycharacterized by comprising 10-60% of a high-activity humic acid organic fertilizer, 10-20% of urea, 10-30% of diammonium phosphate, 10-30% of potassium sulfate, 1-5% of magnesium sulfate, 1-5% of zinc sulfate, 1-5% of calcium oxide, 1-5% of ferrous sulfate, 0.1-0.5% of boric acid, 0.1-0.5% of ammonium molybdate, 0.1-0.5% of manganese sulfate and 0.1-4% of a complexing agent. The high-activity humic acid containing water-soluble liquid fertilizer is prepared according to the technological steps, and large, medium and trace elements and trace elements which are necessary during plant growth arechelated; the high-activity humic acid containing water-soluble liquid fertilizer is rich in activated functional humic acid, various amino acids, multivitamins, mineral elements such as calcium, magnesium, sulfur, iron, zinc, copper, boron, molybdenum, manganese and rare earth, and marine algal organic nutrients.

Description

technical field [0001] The invention is a liquid fertilizer containing high-active humic acid water-soluble fertilizer, especially a preparation method of a liquid fertilizer containing high-active humic acid water-soluble fertilizer suitable for drip irrigation, spray irrigation, soilless cultivation, soil irrigation and foliage spraying . Background technique [0002] In the past two decades, agrochemicals have played a dominant role in agricultural production in my country. In terms of planting, people have used a large amount of chemical fertilizers, pesticides, hormones and other agrochemicals regardless of the bearing capacity of the cultivated land. Coupled with the random discharge of factory waste gas and urban sewage, rural non-point source pollution has entered a vicious circle. The quantitative change of pollutants stresses the soil and loses its fragile self-purification ability, and the soil compaction declines and the vitality is no longer. According to rele...
