Problems solved by technology

If this part of the increasing nitrogen fertilizer input cannot be rationally utilized, and if the loss of nitrogen fertilizer is not controlled as it is at the present stage, it will have a catastrophic impact on the human living environment
[0006] The above facts and data show that in my country's agricultural production, the nitrogen fertilizer utilization rate is low, the loss is large, the fertilizer efficiency is declining, the quality of agricultural products is degraded, the cost of agriculture is increasing, the income of farmers is declining, and the ecological environment is deteriorating. These problems cannot be ignored.

Embodiment 1

[0027] Crush urea and humic acid to 80-120 mesh, bentonite and fluorspar powder to 120 mesh respectively, weigh 350 kg of urea, 250 kg of humic acid, 80 kg of bentonite, and 100 kg of fluorspar powder, and mix and stir the above four ingredients A uniform mixture is obtained.

[0028] Chelating granulation: use equipment such as steam pressure boiler, belt conveyor and transfer granulation drum; use the belt conveyor to mix the materials into the transfer granulation drum, and the steam pipe outlet of the steam pressure boiler is set at the entrance of the transfer granulation drum. Before the mixed material enters the transfer granulation drum, the steam produced by the steam pressure boiler is sprayed into the mixed material through the outlet of the steam pipe, so that the water content in the mixed material reaches 22-25%, and the urine in the mixed material is affected by the high temperature of the steam Melt down and enter the attapulgite crystal structure to obtain a c...

Embodiment 2

[0033] Crush urea and humic acid to 80-120 mesh respectively, crush bentonite and fluorspar powder to 120 mesh respectively, weigh 400 kg of urea, 300 kg of humic acid, 90 kg of bentonite, and 220 kg of fluorspar powder, and mix and stir the above four ingredients A uniform mixture is obtained.

[0034] Chelating granulation: before the mixed material enters the transfer granulation drum, the steam produced by the steam pressure boiler is sprayed into the mixed material through the outlet of the steam pipe, so that the water content in the mixed material reaches 24%, and the others are the same as in Example 1;

[0035] Drying: Use the equipment drying cylinder, input the chelated particles into the drying cylinder, and dry the dried particles with a moisture content of 8.5%;

[0036] Cooling: with embodiment 1;

[0037] Screening: with embodiment 1.

Embodiment 3

[0039] Crush urea and humic acid to 80-120 mesh, bentonite and fluorspar powder to 120 mesh respectively, weigh 450 kg of urea, 350 kg of humic acid, 100 kg of bentonite, and 320 kg of fluorspar powder, and mix and stir the above four ingredients A uniform mixture is obtained.

[0040] Chelating granulation: before the mixed material enters the transfer granulation drum, the steam produced by the steam pressure boiler is sprayed into the mixed material through the outlet of the steam pipe, so that the water content in the mixed material reaches 23%, and the others are the same as in Example 1;

[0041] Drying: use the equipment drying cylinder, input the chelated particles into the drying cylinder, and dry the dried particles with a moisture content of 9%;

[0042] Cooling: with embodiment 1;

[0043] Screening: with embodiment 1.

Abstract

The invention relates to agricultural fertilizers, and especially relates to humic acid urea. The humic acid urea is characterized by being composed of the following raw materials in percent by weight: 35-45% of urea, 25-35% of humic acid, 8-10% of bentonite, and 10-32% of fluorspar powder. Urea has the nitrogen fertilizer content of 46% or more, humic acid is weathered coal which possesses the organics content of 60% or more and humic acid content of 45% or more and is sieved by an 80-120 mesh sieve. Humic acid is capable of inhibiting action of urease, alleviating decomposition of urea and prolonging urea fertilizer efficiency. The humic acid urea has slow-release and long-term release effects in farmland, helps to improve urea utilization rate, gives play to effects of improving product quality, improving soil physical and chemical properties, adjusting soil acid-base value, promoting action of soil microbes, increasing activity of soil enzyme, loosening soil, adjusting water, fertilizer, gas and thermal statuses of soil, promoting plant root growth, enhancing conversion speed of organic inorganic fertilizers in soil, increasing plant chlorophyll, improving plant photosynthesis, improving plant resistance, and preventing soil hardening and desertification and environment pollution caused by excessive application of inorganic fertilizers to soil, and also has the advantages of preventing plant physiological diseases and the like.

Description

[0001] technical field [0002] The invention relates to agricultural chemical fertilizers, in particular to humic acid urea. Background technique [0003] At present, the utilization rate of nitrogen fertilizer or urea in my country is only about 30%, and 20 million tons of nitrogen fertilizer will be lost a year, which is equivalent to the annual output of 100 medium and small nitrogen fertilizer plants, and the economic loss will reach 40 billion yuan. Due to the extensive use of nitrogen fertilizers in modern agriculture, not only groundwater is polluted to varying degrees, but also rivers, rivers, and lakes are polluted to varying degrees. The proportion of polluted waters accounts for 42.5%, and the heavily polluted ones account for 25.6%. [0004] In recent years, the amount of nitrogen fertilizer in my country has skyrocketed. It was 39 kg / ha in the 1970s, 130 kg / ha in the 1980s, 200 kg / ha in the 1990s, and 211 kg / ha at present. The world's average nitrogen fertiliz...
