Abstract
The invention provides a controllable slow-releasing urea fertilizer. It contains slow-releasing compound. The proportion between said fertilizer and slow-releasing compound is 10: 0.5. The slow-releasing compound comprises nitrogen fertilizer synergist, nitrogen fertilizer stabilizer, organic acid, coating membrane agent, surface active agent and conditioner; and the proportioning of said compound is 7:1 : 2: 0.5: 0.1: 3.
Description
Technical field
What the present invention relates to is urea.What be particularly related to is controlled slow release urea fertilizer.
Background technology
Urea is the solid nitrogenous fertilizer of present consumption maximum, has a spot ofly by crop absorption after being manured into soil, and under microbial process, a large amount of is vapored away by leaching loss.Therefore, above-mentioned situation and cause waste impacts water source and air.There are human oils, paraffin dope layer to adhere in the prior art and are wrapped in the granular urea outside, make slow released urea.But, only be applicable to high price crops such as lawn, flowers with the product cost height that aforesaid method is made.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, provide a kind of nitrogenous fertilizer in the urea is discharged in soil slowly, make the absorbent controlled slow release urea fertilizer of farm crop in a long time.
Solving the problems of the technologies described above the technical scheme that is adopted is:
A kind of controlled slow release urea fertilizer, this fertilizer contains slow releasing composition, and the ratio of described this fertilizer and slow releasing composition is 10: 0.5; Slow releasing composition is made up of nitrogen fertilizer potentiating agent, nitrogen stabilizer, organic acid, fruit glaze agent, tensio-active agent, amendment, and the proportioning of forming the slow releasing composition mentioned component is: 7: 1: 2: 0.5: 0.1: 3.
Described nitrogen fertilizer potentiating agent is urease inhibitor and nitrification inhibitor, and wherein urease inhibitor is selected boric acid or Sodium Tetraborate, ferrous sulfate, zinc sulfate, manganous sulfate, sal epsom, copper sulfate, ammonium molybdate, rare earth pin hydrochlorate for use; Described nitrification inhibitor is selected thiocarbamide, two cyanogen ammonium, Sulphathiazole, 2-amino-4-chloro-6-methylpyrimidine for use, is narrowed basic thiocarbamide.
Described nitrogen stabilizer is selected yellow humic acid, hydrolysis amino acid, Lalgine and water capacity salt thereof for use.
Described organic acid is selected xitix, the acid of citric acid bigcatkin willow for use.
Described fruit glaze agent is selected the acid of water capacity polypropylene, polyvinyl alcohol, Mierocrystalline cellulose macromolecular compound for use.
Described tensio-active agent is selected fatty alkyl quaternary amine, halogenation pyridine for use.
Described amendment is selected urea, methyl alcohol for use.
The invention has the beneficial effects as follows:
1. nitrogen utilization efficiency of the present invention improves 5-10 percentage point than common urea.Identical crop yield can save fertile 20%.
Fertilizer efficiency its extend to 60-120 days, repeatedly fertilising is saved the labour for single-dose application again.
3. balanced nutrients, the water conservation drought resisting promotes the healthy and strong growth of farm crop.
Embodiment
Below embodiments of the invention are described in further detail:
The invention provides a kind of controlled slow release urea fertilizer, this fertilizer contains slow releasing composition, and the ratio of described this fertilizer and slow releasing composition is 10: 0.5.
Described slow releasing composition is made up of nitrogen fertilizer potentiating agent, nitrogen stabilizer, organic acid, fruit glaze agent, tensio-active agent, amendment, and the proportioning of forming the slow releasing composition mentioned component is: 7: 1: 2: 0.5: 0.1: 3.
Described nitrogen fertilizer potentiating agent is urease inhibitor and nitrification inhibitor, and wherein urease inhibitor is selected boric acid or Sodium Tetraborate, ferrous sulfate, zinc sulfate, manganous sulfate, sal epsom, copper sulfate, ammonium molybdate, rare earth pin hydrochlorate for use; Described nitrification inhibitor is selected thiocarbamide, two cyanogen ammonium, Sulphathiazole, 2-amino-4-chloro-6-methylpyrimidine for use, is narrowed basic thiocarbamide.
Described nitrogen stabilizer is selected yellow humic acid, hydrolysis amino acid, Lalgine and water capacity salt thereof for use.
Described organic acid is selected xitix, the acid of citric acid bigcatkin willow for use.
Described fruit glaze agent is selected the acid of water capacity polypropylene, polyvinyl alcohol, Mierocrystalline cellulose macromolecular compound for use.
Described tensio-active agent is selected fatty alkyl quaternary amine, halogenation pyridine for use.
Described amendment is selected urea, methyl alcohol for use.
Embodiment:
After getting 10 kilograms in homemade urea, 0.5 kilogram of mixing of slow releasing composition, sending in the conventional tablets press, is granulation 4.5 minutes under the conditions of 40 degree in temperature, then with the oven dry 3.5 minutes under 63 degree of the drying plant of routine.After the work in-process of the above processing of process enter the sub-sieve process, send into wrapping machine and pack.
