Problems solved by technology

But so far, there are few synergists that can be widely used in production. Existing urease inhibitors and nitrification inhibitors include dicyandiamide, n-butylthiophosphoric triamide, 3,4 Dimethylpyrazole phosphate, 2-chloro-6-trichloromethylpyridine, etc., but the time of action is short, and the inhibitory effect is easily affected by temperature. Residue in the body; repeated application of accelerated degradation rate, shortened half-life and other issues, the present invention found that 2-cyclopentenone can simultaneously have dual functions of nitrification inhibition and urease inhibition, the material has the advantages of environmental friendliness, good inhibition effect, low cost, etc.

Embodiment 1

[0024] By synergist, by 100 parts of urea (N, 46%), after 2-cyclopentenone is measured according to the ratio of 2% of fertilizer nitrogen content, directly join in the molten urea of ​​urea production process with feeder, mix Uniform, granulated to obtain stable urea containing 2-cyclopentenone.

Embodiment 2

[0026] Using fluidized bed technology to spray coating, 50 parts of acrylic resin RS100 and 50 parts of ethyl cellulose used for coating are dissolved in 1000 parts of ethanol solvent, wherein the total miscible amount of acrylic resin RS100 and ethyl cellulose is fertilizer 10% of core weight; Add synergist 2-cyclopentenone (according to 3% of fertilizer nitrogen content to add) in this solution again, 5 parts of inorganic membrane conditioner zeolite powders, then add 4 parts of plasticizer poly Ethylene glycol, mixed and poured into the fluidized bed liquid tank, sprayed on the surface of large-grained urea (N, 46%). Among them, the operating parameters of the fluidized bed coating machine are: the compressed air pressure is 0.3Pa, the nozzle fog pressure is 0.15Pa, and the inlet air temperature is 75 degrees Celsius.

Embodiment 3

[0028] After fully mixing 28.6 parts of pulverized urea (N, 46%), 28.6 parts of diammonium phosphate (N, 18%) and 2-cyclopentenone (added according to 5% of the nitrogen content of the fertilizer), after granulation, drying Dried, sieved, and cooled to make a slow-release long-acting compound fertilizer containing the synergist 2-cyclopentenone.

Abstract

The invention relates to the field of chemical fertilizers, in particular to an application of 2-cyclopentenone as a synergist in a nitrogen-containing fertilizer, and the additive amount of the synergist 2-cyclopentenone in the nitrogen-containing fertilizer is 1-10% of the nitrogen content in the fertilizer. 2-cyclopentenone has a bidirectional regulation and control function, can inhibit hydrolysis of urea to achieve a urease inhibition effect, can delay conversion from ammonium nitrogen to nitrate nitrogen to achieve a nitrification inhibition effect, and has the advantages of being good in action effect, green, environmentally friendly and the like.

Description

technical field [0001] The invention relates to the field of chemical fertilizers, in particular to the application of 2-cyclopentenone as a synergist in nitrogen-containing fertilizers. Background technique [0002] Fertilizer is one of the decisive factors for high grain yield and high quality. According to statistics, chemical fertilizers account for 40-60% of the increase in yield. Due to the limitation of fertilizer technology in our country, the nutrient utilization rate is low, which has caused great waste and environmental problems. At present, the average utilization rate of chemical fertilizers in developed countries in the world is 50-60%, of which nitrogen fertilizer is 50-70%. However, the utilization rate of nitrogen fertilizer in my country is only 30-35%, and that of phosphorus fertilizer is 10-25%, which is 15-20 percentage points lower than that of developed countries. About 13 million tons of nitrogen enter the atmosphere and water bodies every year, and ...
