Abstract
The invention discloses a special peanut film-coating slow-release fertilizer and a preparation process thereof. The special peanut film-coating slow-release fertilizer utilizes the effects of exchange, adsorption, combination and chelation of humic acid, and a reactant, a cross-linking agent and a film-forming agent are added to the humic acid to prepare a special peanut slow-release film-coating agent; then special peanut slow-release film-coating agent is mixed with a proportioned special peanut fertilizer; and an obtained mixture is subjected to granulating, film coating, dehumidifying, cooling and screening to prepare the special peanut film-coating slow-release fertilizer. The humic acid contained in the special peanut film-coating slow-release fertilizer is a high-quality organic fertilizer, and not only can be decomposed to provide nutrients, but also can stimulate the activity of root nodules, enhance the nitrogen fixing capacity and improve the disease resistance and the continuous cropping resistance. The special peanut film-coating slow-release fertilizer and the preparation process not only are a break of a slow-release technology of the fertilizer industry, but also are the perfection and the improvement of a peanut fertilizing technology, and achieve the purposes of increasing the yield, reducing the cost and realizing high efficiency on peanut production.
Description
Technical field
The present invention relates to a kind of slow release fertilizer and manufacturing process thereof, especially cultivate peanut special-purpose a slow release fertilizer and a manufacturing process thereof.
Background technology
Lower and the heavy dressing of fertilizer utilization ratio is to the influence of ecotope, both at home and abroad fertilizer industry and related scientific research department always the slow controlled-release technology of fertilizer as emerging subject study.
What China carried out the slow-release fertilizer research work the earliest is since 72 years, and 85 years is the success of coating agent coated urea with ammonium phosphate sylvite.Progressively develop with the slow controlled-release technology of materials such as plastics, resin, paraffin, polyethylene, elementary sulfur as the coating agent.China has developed into the country of sustained-controll-release fertiliser most species in the world.
According to statistics, in the demonstration area of using sustained-controll-release fertiliser, chemical fertilizer this season utilization ratio is up to more than 60%, and more common chemical fertilizer utilization ratio is doubled; Reduce 10～15 kilograms/mu of fertilizer amounts, can be 75～127 yuan/mu of peasant's cost-saving synergistics.Simultaneously, use a large amount of nitrogen that sustained-controll-release fertiliser avoided excessive fertilization to cause, the loss of phosphoric, reduced widespread pollution from the overuse of fertilizers and pesticides in rural area, its economy, society, environmental benefit are fairly obvious.
In recent years, be that the recent studies on achievement of representative is come out one after another with a collection of research institutions such as Shandong Agricultural University, China Agricultural University, make the slow controlled-release technology of China that new development and submission arranged again.Work out chitosan coated dose.Polyolefin polymer, silica gel and degraded starch are mould material.The technology of processing and carrier have also continued on the slow release method of sulfuration bed coating technology and single fertilizer urea.Fertilizer carrier is single.Fail to make the slow controlled-release technology that matches at the fertile existing rule of the suction of Different Crop, control is not and special, and the fertile rule rate of the release of fertilizer and the suction of crop misfits, and this also is that slow release fertilizer is big
The field does not show one of problem of huge vitality on producing.
Peanut is owing to be leguminous crop, and the habit of its fixed nitrogen and geocarpy has formed the fertile rule of the distinctive suction of peanut.Peanut needs fertile less middle and later periods fertilizer requirement big and owing to take the planting patterns of omnidistance membrane covering, fertilising brings difficulty to peanut in earlier stage, and the only reliable disposable base fertilizer of the fertilising of peanut solves the fertile problem of omnidistance need in other words.Therefore, slow release method is even more important in the production of peanut.
Humic acids is the macromole aromatic hydroxy-carboxylic, basic structure is aromatic ring and alicyclic ring, be connected with hydroxyl, carboxyl, carbonyl, quinonyl, methoxy group material on the ring, can utilize its exchange absorption in conjunction with sequestering action, add neutralization and cross-linked material and make it produce high molecular polymerization, form the macromolecule filming material.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of special peanut film-coating slow-release fertilizer and manufacturing process thereof, the special peanut film-coating slow-release fertilizer that is made by method of the present invention is not only the breakthrough of fertilizer trade slow release method, the improving and improve of peanut fertilizer practice especially played volume increase, subtracted, purpose efficiently in peanut production.
The present invention for the technical scheme that solves its technical problem and adopt is:
