Embodiment 1

[0018] 1. Preparation of active weathered coal containing active humic acid

[0019] Weigh the following materials into the activation reaction tank:

[0020] (1) Water (tap water or underground well water) 35kg, water temperature 20°C;

[0021] (2)K 2 CO 3 (content 98.5%) 4.5kg;

[0022] (3) 50kg of weathered coal (from Huolinhe Coal Mine, HA content is 60.1%, particle size is above 60 mesh):

[0023] Under the condition that stirring speed is 50 rev / mins, after above-mentioned material is stirred for 15 minutes, add hydrogen peroxide 5kg (its weight percent composition is 29%) in activation reaction tank again, rise to stirring speed to be 200 rev / mins simultaneously Separate, react at 27°C for about 5 minutes, after the material forms a porous bulk, pour it on the drying field to dry naturally, pulverize, and sieve (20 mesh), that is, active weathering with uniform particle active humic acid content of 61.3%. coal.

[0024] 2. Preparation of humic acid solid fertilize...

Embodiment 2

[0037] Embodiment 2 Preparation of active weathered coal containing active humic acid

[0038] Put 50Kg of weathered coal with a particle size of 100 mesh and a humic acid content of 50% in an activation reaction tank, start stirring at a speed of 50 rpm, and add 40Kg of water and 4.5Kg of K 2 CO 3 , after stirring for 20 minutes, add 7Kg H 2 o 2 At the same time, increase the stirring speed to 300 rpm, and react at 35°C for 5 minutes, and the reaction product is naturally aired for 8 hours. After drying, it is slightly rolled and sieved (20 mesh), and the active weathered coal with uniform particles is formed. . The weight percentage of active humic acid is 80.60% after testing.

Embodiment 3

[0039] Embodiment 3 Preparation of active weathered coal containing active humic acid

[0040] Put 50Kg of weathered coal with a particle size of 100 mesh and a humic acid content of 50% in an activation reaction tank, start stirring at a speed of 50 rpm, and add 30Kg of water and 3.5Kg of Na 2 CO 3 , 2KgNH 4 HCO 3 , after stirring for 20 minutes, add 1Kg potassium percarbonate and 4Kg H 2 o 2 At the same time, the stirring speed was increased to 500 rev / min, and reacted for 5 minutes at 25°C to form a bulky body. The reactant was poured out and moved to the drying field. After natural drying for 5 hours, it was slightly rolled and sieved (20 mesh), that is, to form active weathered coal with uniform particles. The weight percentage of active humic acid is 74.0% after testing.

Abstract

The invention discloses a humic acid solid fertilizer, which comprises (by weight ratio based on 100 parts) nitrogen 4-40 parts, phosphor 3-35 parts, potassium 3-40 parts, secondary elements 0-6.5 parts, trace element 0-1.5 parts, reactive humic acid 15-30 parts, water-soluble chitosan 0-1.0 parts, wherein the reactive humic acid is provided by reactive weathered coal containing the reactive humic acid. The invention also discloses the preparation of reactive weathered coal.

Description

technical field [0001] The invention relates to a solid fertilizer, in particular to a humic acid solid fertilizer. Background technique [0002] Due to the long-term application of large amounts of chemical fertilizers in my country's farmland, it has caused hazards such as soil compaction, salinization, and pollution. Moreover, the quality and taste of crop products have become worse and worse. The nitrate content in vegetables has seriously exceeded the standard, threatening human health. Therefore, People vigorously advocate and implement measures such as returning orange stalks to the field in order to increase the application amount of organic fertilizers, but objectively, the raw materials for producing organic fertilizers are very limited and cannot meet the needs of large-scale farmland. [0003] The development and application of humic acid fertilizers have increased the sources of organic fertilizers, and at the same time ideally made up for the respective deficien...
