Embodiment 1

[0020] The synergist, according to 100 parts of urea (N, 46%), 2-cyclopentenclod, according to 2% of the fertilizer nitrogen content, directly using the feeder to the urea production process, molten urea, mix Uniform, produced stabilizing urea containing 2-cyclopentenone.

Embodiment 2

[0022] The envelope was sprayed with a fluidized bed, 50 parts of acrylic resin RS100 and 50 parts of the membrane were dissolved in 1000 parts of the ethanol solvent in which the acrylic resin RS100 and ethylcellulose misculudes were total 10% of the core weight; addition of a synergent 2-cyclopentenone (addition of the fertilizer nitrogen content), 5 parts of the inorganic film conditioning zeolite, then add 4 plasticizers Ethylene glycol, mixed into the fluidized bed tank after mixing, sprayed on the surface of large particles (N, 46%). The operating parameters of the fluidized bed envelope machine are: the compressed air pressure is 0.3Pa, the spray spray pressure is 0.15 Pa, the air intake temperature is 75 degrees Celsius.

Embodiment 3

[0024] 28.6 of the pulverized urea (N, 46%), 28.6 parts of diamnesate (N, 18%) and 2-cyclopennone (addition of 5% of the fertilizer nitrogen content) were fully mixed, Dry, screening, cooling, so that the sustained release of the synergist 2-cyclopennone is made.

Abstract

The invention provides a synergist using a 2-cyclopentenone-containing compound as a nitrogen-containing fertilizer. The synergist comprises the components by weight: 5-25 parts of benzoic acid, 3-20 parts of 2-cyclopentenone, 1-30 parts of dihydrojasmonone, 10-60 parts of glycerol and 20-55 parts of yeast liquid powder. The novel synergist is applied to the nitrogen-containing fertilizer, and the nitrogen-containing fertilizer can be prepared. The addition amount of the synergist in the nitrogen-containing fertilizer is 0.1-1% of the nitrogen content in the fertilizer. The preparation method comprises the following steps: a first method comprising the steps of spraying and wrapping the synergist on the surface layer of the fertilizer; a second method comprising the steps of mixing with a grain-level powdery nitrogen fertilizer, and granulating the nitrogen fertilizer to form a stable fertilizer; a third method comprising the steps of adding into a urea production system to form urea; and a fourth method comprising the steps of spraying and granulating ammonium phosphate. The synergist has a bidirectional regulation function, can inhibit hydrolysis of urea to play a role in urease inhibition, can delay conversion from ammonium nitrogen to nitrate nitrogen to play a role in nitrification inhibition, and also has the advantages of good action effect, environmental protection and the like.

Description

Technical field [0001] The present invention relates to the field of chemical fertilizers, and in particular, a 2-cyclopenne complex is used as a synergist of nitrogen-containing fertilizers. Background technique [0002] Fertilizers are one of the decisive factors of food and quality. According to statistics, the role of fertilizers in the production of yields accounted for 40 to 60%. Due to the particularity of nitrogen and its characteristics of rapid conversion in the soil, the nutrient utilization is low, causing great waste and environmental issues. At present, the world's developmental national fertilizer utilization rate is 50 ~ 60%, while the nitrogen utilization rate of regional nitrogen fertilizer is only 30 ~ 35%, and the utilization rate is 15 ~ 20 percentage points lower than the developed country. There are a large amount of nitrogen every year. To the atmosphere and water. At present, most of the world are still using traditional low-nitrogen fertilizers, with hig...
