Embodiment 1

[0041] The special fertilizer for desert and desertification control is composed of the following raw materials in weight percentage: 69% of weathered lignite, 23% of ammonium bicarbonate, 5% of monoammonium phosphate, and 3% of potassium sulfate.

[0042] Embodiment 1 The special fertilizer for desert and desertification control is made according to the following preparation method: first, the weathered lignite is pulverized to the weathered lignite powder that can pass through a 120 mesh sieve fineness, and then the weathered lignite powder: ammonium bicarbonate=69: 23% by weight and water, stir and mix evenly, heat at 60°C for 2 hours after fully mixing, and then seal for 7 days to form ammonium humate; then dry ammonium humate at 65°C for 2 hours to make it contain The water content is less than 10%, and finally mixed with 5% monoammonium phosphate and 3% potassium sulfate by weight, and the mixture is crushed by a pulverizer to a fineness that can pass through an 80-mesh s...

Embodiment 2

[0044] The special fertilizer for desert and desertification control is composed of the following raw materials in weight percentage: 50% of weathered lignite, 30% of ammonium bicarbonate, 10% of diammonium phosphate, and 10% of potassium sulfate.

[0045] Embodiment 2 The special fertilizer for desert and desertification control is made according to the following preparation method: first, the weathered lignite is pulverized to the weathered lignite powder that can pass through a 300 mesh sieve fineness with a pulverizer, and then the weathered lignite powder: ammonium bicarbonate=50: 30% by weight and water, stir and mix evenly, mix thoroughly, heat at 50°C for 3 hours, and then seal for 10 days to form ammonium humate; then dry ammonium humate at 80°C for 1 hour to make it contain The amount of water is less than 10%, and finally mixed with 10% by weight of diammonium phosphate and 10% of potassium sulfate, and the mixture is crushed by a pulverizer to a fineness that can pa...

Embodiment 3

[0047] The special fertilizer for desert and desertification control is composed of the following raw materials in weight percentage: 70% of weathered lignite, 15% of ammonium bicarbonate, 8% of monoammonium phosphate, and 7% of potassium chloride.

[0048] Embodiment 3 The special fertilizer for desert and desertification control is made according to the following preparation method: first, the weathered lignite is pulverized to the weathered lignite powder that can pass through the fineness of 80 mesh sieves with a pulverizer, and then the weathered lignite powder: ammonium bicarbonate=70: 15% by weight and stir to mix evenly, mix thoroughly and heat at 70°C for 1 hour, then seal for 5 days to form ammonium humate; then dry ammonium humate at 50°C for 3 hours to make the water content It is less than 15%, and finally mixed with 8% monoammonium phosphate and 7% potassium chloride by weight, and the mixture is crushed by a pulverizer to a fineness that can pass through a 70-mes...

Abstract

The invention relates to a special fertilizer for the desert and desertification control and the preparation method. The special fertilizer comprises the following materials in weight percentage: humic acidic ammonium of 80 percent to 95 percent; monoammonium phosphate, diammonium phosphate or double superphosphate of 3 percent to 10 percent, potassium sulfate or potassium chlorate of 2 percent to 10 percent; or the special fertilizer comprises the following materials in weight percentage: humic acid ammonium of 80 percent to 97 percent and monopotassium phosphate of 3 percent to 20 percent. The preparation method of the special fertilizer comprises: the humic acid ammonium is prepared; the humic acid ammonium of 80 percent to 95 percent, the monoammonium phosphate, diammonium phosphate or double superphosphate of 3 percent to 10 percent and the potassium sulfate or potassium chlorate of 2 percent to 10 percent are mixed fully and uniformly; or the humic acid ammonium of 80 percent to 97 percent and the monopotassium phosphate of 3 percent to 20 percent are mixed fully and uniformly; the admixture is grinded into 70 to 90 mesh. The invention has the advantages that the special fertilizer of the invention can improve the soil physicochemical properties and has a coacervation on sand, simultaneously the special fertilizer can stimulate the growth of the root of the green crop for sand control and strengthen the sand stabilization and drought-resistant capacity.

Description

technical field [0001] The invention relates to a special organic fertilizer and a preparation method thereof, in particular to a special fertilizer for desert and desertification control and a preparation method thereof. Background technique [0002] The control of desert and desertification is a major topic of ecological environment protection and control in our country. my country's existing desert area is 1.7 million square kilometers, accounting for 18% of the total land area, and it is increasing at a rate of 2,460 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. At present, the status quo of deserts and 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] Over the years, my country has done a lot of research and co...
