Embodiment 1

[0028] Embodiment 1 produces total nutrient (N+P 2 o 5 +K 2 O) ≥ 20% vegetable paste fertilizer 1 ton.

[0029] Processing technology of water-soluble humic acid paste fertilizer:

[0030] Formula: weathered coal powder 343kg, potassium chloride 60kg, potassium sulfate 111.2kg, urea 147.8kg, monoammonium phosphate 61.3kg, medium and trace element compounds 10kg, sodium hydroxide 25kg, polyacrylamide 1kg, water 240.7kg. (Water has evaporation loss during the production process, the amount should be increased appropriately, and the increased amount should be adjusted by measuring the product)

Abstract

Disclosed is a grease-form water-soluble humic acid fertilizer, which comprises (by weight percent) 20-45% of weathered coal powder, 10-35% of urea, 5-15% of phosphoric ammonium, 3-25% of potassium chloride, 4-30% of potassium sulfate, 0-20% of raw material containing N, P, K, 0-5% of medium and trace element compounds, 1.0-3.55 of sodium hydroxide, 0.1-0.5% of polyacrylamide, and 15-35% of water.

Description

technical field [0001] The invention relates to a humic acid fertilizer, in particular to a water-soluble humic acid paste fertilizer and a processing method thereof. Background technique [0002] Compared with chemical fertilizers, humic acid fertilizers have obvious effects of increasing production, improving the quality of agricultural products, improving plant nutrient utilization, saving resources, reducing diseases, preventing environmental pollution caused by chemical fertilizers and pesticides from the source, improving soil, drought resistance, Excellent qualities such as cold resistance and salt-alkali resistance are gradually accepted by farmers and become an important member of the fertilizer family. [0003] When processing humic acid solid fertilizers, humic acid raw materials are often activated first to increase their water solubility. This process generally requires water as a medium to achieve. After activation, it must be dried to remove excess water, and ...
