preparation example Construction

[0025] A kind of preparation method of ecological organic compound fertilizer of the present invention is:

[0026] Step 1, prepare ammonium humate:

[0027] Pulverizing the lignite into lignite powder with a fineness of 120-350 meshes;

[0028] Fully mixing 65-75% by weight of the lignite powder, 8-12% urea, 15-25% ammonium bicarbonate, and 1-15% clear water;

[0029] heating the above mixture at 60-70°C for 3-5 hours;

[0030] Let the above mixture dry for 5-15 hours.

[0031] Seal the air-dried mixture for 5-10 days.

[0032] The sealed mixture is then dried at 60-75° C. for 3-4 hours to make the water content less than 10 percent to obtain ammonium humate.

[0033] Step 2, the weight percent of ammonium humate prepared above is 80-90% ammonium humate, add 10-15% xylose powder, 4-7% heavy superphosphate and mix well; grind the above mixture to 90% -110 mesh fineness.

[0034] The ammonium humate produced after sealing is not easy to decompose and lose, and can undergo...

Embodiment 1

[0038] An ecological organic compound fertilizer is made according to the following preparation method: first, the lignite is pulverized into lignite powder that can pass through a fineness of 140 mesh sieves, and then the lignite powder is 70%, urea 10%, and ammonium bicarbonate 15%. Stir and mix evenly with 8% water, mix thoroughly and heat at 65°C for 4 hours, dry the heated mixture for 7 hours, and then seal it for 8 days to form ammonium humate; then put ammonium humate at 65°C Dry for 3 hours to make the water content 10%, and then obtain ammonium humate.

[0039] The above-mentioned gained ammonium humate weight percentage is 92% and weight percentage is 5% xylose powder, 3% superphosphate stirring and mixing evenly, the mixture is pulverized to the fineness that can pass through 110 mesh sieves through pulverizer, Packing into bags is the finished product of ecological organic compound fertilizer.

Embodiment 2

[0041] An ecological organic compound fertilizer is made according to the following preparation method: firstly, the lignite is pulverized into a lignite powder that can pass through a 320 mesh sieve, and then the lignite powder is 60% by weight, urea is 15%, and ammonium bicarbonate is 23%. % and 23% water, stir and mix evenly, after fully mixing, heat at 50°C for 3.5 hours, dry the heated mixture for 12 hours, and then seal it for 12 days to form ammonium humate; then bake ammonium humate at 80°C Dry for 3 hours so that the water content is 8% to obtain ammonium humate.

[0042] The above-mentioned gained ammonium humate weight percentage is that 85% and weight percentage are 10% xylose powder, 5% superphosphate stirring and mixing evenly, the mixture is pulverized to the fineness that can pass through 90 mesh sieves through pulverizer, Packing into bags is the finished product of ecological organic compound fertilizer.

Abstract

The invention discloses an organic composite fertilizer and a preparation method thereof. The organic composite fertilize comprises 80 to 90% of ammonium humate, 10 to 15% of xylose powder and 1 to 3% of concentrated superphosphate, wherein the ammonium humate is a mixture obtained by fully mixing raw materials consisting of 65 to 75% of brown coal powder, 8 to 12% of urea, 15 to 25% of ammonium bicarbonate and 1 to 15% of clear water. The ecological organic composite fertilizer can improve physical and chemical properties of soil and survival capability of ecological vegetation crops; and the preparation method is simple, is convenient for popularization and popularization and has low production cost and good economic benefits.

Description

technical field [0001] The invention belongs to the technical field of organic chemical industry, and in particular relates to an organic compound fertilizer and a preparation process thereof. Background technique [0002] The control of desertification is a major issue in my country's ecological environment and governance. my country's existing desert area is 1.74 million square kilometers, accounting for 18% of the total land area, and it is increasing at a rate of 3460 square kilometers every year. If the Gobi Desert and desertification area are added, the total area accounts for about 30% of the total land area of ​​the country. The current situation of desertification in our country has threatened our living space, and controlling deserts and desertification is a century-old plan that we need to continue to work hard for a long time. [0003] my country suffers from long-term drought and water shortage, expanding land desertification area, poor fertility, low producti...
