Problems solved by technology

[0003] In recent decades, a large number of chemical fertilizers mainly composed of nitrogen, phosphorus and potassium have been used in my country's agriculture. It has greatly changed the situation of low yields of farmyard manures in the past, and has doubled crop yields. However, long-term use of chemical fertilizers will cause It leads to soil compaction and the decline of crop quality. With the use of the same amount of chemical fertilizer, the yield also tends to decline year by year; there is an urgent need for a new type of fertilizer that avoids the above-mentioned disadvantages in agriculture.

Embodiment 1

[0034] The weathered coal with a humic acid content of 50% (dry basis) and a water content of about 30% is evenly sprayed into 100 kg of 3% NaOH solution per ton of weathered coal before stacking, and is naturally ventilated and dried for more than half a month. After removing impurities such as gangue Pulverize and pass through a 60-mesh sieve to obtain weathered coal powder. Add 1 ton of weathered coal powder to a solution prepared by adding 120 kg of ammonium bicarbonate, 112.5 kg of potassium chloride and 700 kg of tap water, stir evenly in a mixer, heat up to 80-90°C for 1 hour, and then dry it in a spin flash dryer. Dried to obtain black weathered coal powder with a water content lower than 24%, according to active weathered coal: urea: diammonium phosphate: potassium chloride=53.9: 17.2: 12.1: 16.8, after weighing respectively, add in the mixer and mix evenly Pulverize through a 60-mesh sieve to obtain N:P 2 o 5 : K 2 O=1:0.5:1.2, N+P 2 o 5 +K 2 O≥30% of powdered ...

Embodiment 2

[0036] The weathered coal with a humic acid content of 50% (dry basis) and a water content of about 30% is evenly sprayed into 100 kg of 3% NaOH solution per ton of weathered coal before stacking, and is naturally ventilated and dried for more than half a month. After removing impurities such as gangue Pulverize and pass through a 60-mesh sieve to obtain weathered coal powder. Add 120 kg of ammonium bicarbonate and 150 kg of potassium nitrate to 1 ton of weathered coal powder and add 600 kg of tap water to make a solution. Stir evenly in a mixer and heat up to 80-90°C for 1 hour. , and then dry in a rotary flash dryer to obtain black active weathered coal powder with a water content lower than 24%, weighing respectively by active weathered coal: urea: diammonium phosphate: potassium sulfate=52.5: 15.2: 12.1: 20.2 Then add it to the mixer and mix it evenly, and then grind it to 60 mesh by a pulverizer to get N:P2 o 5 :K2O=1:0.5:1.2, N+P 2 o 5 +K 2 O≥30% of powdered products....

Abstract

A mixed active humate fertilizer is prepared from active weathered coal powder, urea, ammonium phosphate, potassium chloride, potassium sulfate and ordinary and trace elements through spraying said weathered coal powder in NaOH solution, natural drying, sieving, mixing with the solutions of ammonium hydrogen carbonate and potassium chloride (or nitrate), heating, reacting, drying, mixing with others, pulverizing and granulating. Its advantages are complete nutrients and low cost.

Description

technical field [0001] The invention relates to an organic compound fertilizer, in particular to an active humic acid compound fertilizer and a processing method thereof. Background technique [0002] Due to the complex organic structure of humic acid itself, when it is made into fertilizer, it has a good effect of improving soil. On the one hand, it can promote the formation of soil aggregate structure, making the soil a fertile soil suitable for the growth of crops with ventilation, water storage and fertilizer retention; it can enhance the buffering property of the soil and improve low-yield soil; it can form a relatively stable complex with urea, Form double salts with phosphate and calcium ions, and form chelates with metal ions needed by many crops in the soil, which can store and replenish crop nutrients, thereby providing balanced nutrition to crops and avoiding the loss of nutrients , so that its utilization rate is greatly improved. On the other hand, it can also...
