Embodiment 1

[0023] A kind of humic acid polylose fertilizer, it is prepared according to the following method:

[0024] 1) Weighing of raw materials: Weigh 300 kg of urea, 400 kg of ammonium chloride, 100 kg of potassium chloride, 80 kg of sodium hydroxide, 300 kg of humic acid, and set aside;

[0025] 2) Paste material liquid preparation: Add sodium hydroxide and humic acid into the stirring tank and stir and mix for 15 minutes. When the reaction temperature reaches 50-60°C, send the materials in the stirring tank into the reactor. Add urea and ammonium chloride to the mixture and feed water vapor, keep the heat for 15 minutes to get a pasty feed liquid;

[0026] 3) Fertilizer A preparation: send the pasty feed liquid obtained in step 2) into a high-tower granulator, and simultaneously add potassium chloride for granulation, drying and screening to obtain fertilizer A;

[0027] 4) Preparation of bacterial agent: the active ingredients of the bacterial agent include the following raw mat...

Abstract

The invention discloses a humic acid nutrient-gathering fertilizer, comprising urea, ammonium chloride, potassium chloride, sodium hydroxide and humic acid. The humic acid nutrient-gathering fertilizer also comprises a microbial agent. With the addition of the humic acid and microbial agent, compared with a conventional composite fertilizer, the nutrient-gathering fertilizer can greatly improve soil structure, controls the loss of nutrient during usage process, has the functions of making crops high and stable yield, uniform emergence of strong seedlings, and has relatively good market application value.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a humic acid polylosing fertilizer and a production method thereof, also known as humic acid low-carbon fertilizer. Background technique [0002] After entering the 21st century, with the development of modern agricultural production, people are looking forward to the emergence of fertilizers with long-lasting fertilizer effects and less loss in the field of fertilizers, which can improve the soil, increase the yield and quality of crops, increase production efficiency, reduce production or improve labor. conditions and protect the natural environment. Due to the excessive use of soil, most of the soil currently has many problems, such as poor nutrient absorption capacity of crops, inactive soil, poor water and fertilizer retention capacity, serious soil salinization caused by successive years of sedimentation, serious soil-borne diseases, and trace ...
