Abstract

The invention provides a liquid fertilizer containing a humic acid. The liquid fertilizer containing the humic acid comprises the following components in parts by mass: 45-50 parts of water, 30-40 parts of monopotassium phosphate, 8-9 parts of potassium hydroxide, 20-35 parts of urea, 1-5 parts of heptahydrate, 2-5 parts of borate decahydrate, 0.5-1 part of ammonium molybdate tetrahydrate, 5-10 parts of potassium fulvate, 0.1-0.5 part of growth modifier, and 0.1-0.5 part of surfactants. The nitrogen, phosphorus and potassium content in each liter of the liquid fertilizer obtained by using the method disclosed by the invention is increased to 460g, the content of the humic acid can be up to 45g, no sediment is generated, the pipe is not easily blocked, the content of effective ingredients of the liquid fertilizer is greatly increased, and crop growth is facilitated.

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...
