Problems solved by technology

[0004] Straw accounts for about 50% of the biological yield of crops. It is a kind of extremely rich renewable organic resources. According to the research and analysis of the relevant research group of the Regional Planning Institute of the Chinese Academy of Agricultural Sciences, there are about 620 million tons of straw in my country every year. Most of these straws are burned in vain. A large amount of resources are wasted, the agricultural ecological balance is destroyed, and the environment is polluted

Embodiment 1

[0028] The preparation of embodiment 1 compound fertilizer

[0029] Put the wheat stalks into a closed furnace at 450°C for carbonization to obtain organic colloids with very small particles in batches, and mix them evenly into chemical fertilizers at a weight ratio of 1:1 (N:P:K=12:9:8 )middle. The molasses fermentation liquid (purchased from Taiwan Vedan Group, with an amino acid content of about 35%) was mixed with the compound amino acid contained in it, boric acid, borax, ammonium molybdate, copper sulfate, ferrous sulfate, manganese sulfate, zinc sulfate, and calcium nitrate in moles. Mix at a ratio of 1:0.8:0.2:1.2:0.7:0.8:0.6:0.4:0.3, adjust the pH value to 7.5 with calcium hydroxide, stir evenly, react at 25°C for 1 hour, and spray the chelating liquid evenly on the mixed organic The surface of the colloidal chemical fertilizer makes the total content of chelated trace elements reach 2% (dry weight), and the primary mixed fertilizer is obtained. Then mix the weather...

Embodiment 2

[0030] The preparation of embodiment 2 compound fertilizer

[0031]Put wheat stalks into a closed furnace at 400°C for carbonization treatment to obtain organic colloids with very small particles in batches, and mix them evenly into chemical fertilizers at a weight ratio of 1:2 (N:P:K=7:8: 7). The molasses fermentation liquid (purchased from Taiwan Vedan Group, with an amino acid content of about 35%) was mixed with the compound amino acid contained in it, boric acid, borax, ammonium molybdate, copper sulfate, ferrous sulfate, manganese sulfate, zinc sulfate, and calcium nitrate in moles. Mix at a ratio of 1:0.8:0.2:1.2:0.7:0.8:0.6:0.4:0.3, adjust the pH value to 7.0 with calcium hydroxide, stir evenly, react at 28°C for 1 hour, and evenly spray the chelating liquid on the mixed organic The surface of the colloidal chemical fertilizer makes the total content of chelated trace elements reach 2% (dry weight), and the primary mixed fertilizer is obtained. Then weathered coal is...

Embodiment 3

[0032] The preparation of embodiment 3 compound fertilizer

[0033] Put the corn stalks into a closed furnace for carbonization at 500°C to obtain organic colloids with very small particles in batches, and mix them evenly into chemical fertilizers (urea) at a weight ratio of 2:1. The molasses fermentation broth (purchased from Taiwan Weidan Group) was mixed with the compound amino acid contained in boric acid, borax, ammonium molybdate, copper sulfate, ferrous sulfate, manganese sulfate, and zinc sulfate in a molar ratio of 1:0.8:0.2:1.2:0.7 : 0.8: 0.6: 0.4, mixed with calcium hydroxide to adjust the pH value to 8.0, stirred evenly, reacted at 23°C for 1 hour, and sprayed the chelating liquid evenly on the surface of the fertilizer mixed with organic colloid to make the total amount of chelated trace elements When the content reaches 3% (dry weight), the primary mixed fertilizer is obtained. Then mix the weathered coal with ammonium bicarbonate, borax, copper sulfate, ferrous...

Abstract

The invention provides an organic-inorganic compound fertilizer. The fertilizer contains organic colloid, inorganic nutrients and chelated medium-trace elements. The fertilizer can reduce fertilizer loss, improve the utilization rate of the fertilizer, reduce energy consumption, protect environment and improve the utilization rate of the medium-trace elements, and is a novel compound fertilizer with high application value.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to an organic-inorganic compound fertilizer rich in organic colloids and a production method thereof. The fertilizer is rich in organic colloids, inorganic nutrients and chelated medium and trace elements, and is specially used to reduce the loss of chemical fertilizers, supplement crop deficiency symptoms, and repair soil problems. Background technique [0002] my country is famous all over the world for raising 22% of the world's population with 7% of the world's arable land, and the use of chemical fertilizers is indispensable. But decades later, the disadvantages caused by the loss of up to 70% of the chemical fertilizers in the soil have become serious. In order to make up for the 70% lost nutrients, farmers have to increase the amount of fertilizer. The more you give, the more you lose. A large amount of chemical fertilizers are carried away by running water during heavy rain or f...
