Abstract

The invention provides a humic acid-containing liquid fertilizer. The humic acid-containing liquid fertilizer is composed of the following components in parts by mass: water: 45-50 parts; potassium dihydrogen phosphate: 30-40 parts; potassium hydroxide: 8-9 parts; urea: 20-35 parts; zinc sulfate heptahydrate: 1-5 parts; boric acid decahydrate: 2-5 parts; ammonium molybdate tetrahydrate: 0.5-1 parts; potassium fulvic acid: 5-10 parts parts; growth regulator 0.1-0.5 parts; surfactant 0.1-0.5 parts. The content of nitrogen, phosphorus and potassium per liter of the liquid fertilizer produced by the method of the present invention is increased to 460 grams, and the content of humic acid reaches 45 grams. There is no precipitation, and it is not easy to block the pipeline, which greatly improves the content of active ingredients in the liquid fertilizer. , which is conducive to promoting crop growth.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a liquid fertilizer containing humic acid. Background technique [0002] Liquid fertilizer has the following advantages: ① easy to absorb, quick effect; ② dissolved and diluted without cooling, easy to evenly distribute in the soil after application, unlike solid fertilizers that form concentrated fertilization with high local salinity, and are not easy to frostbite roots and seedlings; ③ can be sprayed, dripped or Watering, easy to use, low cost, and quick results; ④It can be mixed with insecticides, fungicides, and herbicides and can be mixed evenly; ⑤It will not segregate like solid fertilizers during storage and transportation, resulting in uneven quality; ⑥The product does not absorb moisture and agglomeration problems; ⑦ There will be no dust, smoke and less pollution during production, application and transportation. Therefore, liquid fertilizer is one of the trends i...
