Abstract
The present invention relates to a kind of method for preparing particle magnesium fertilizer.This method is that light-burning magnesium powder and silica are made granular fertiliser containing magnesium through chemistry and physical reaction.Technology of the present invention is simple and easy to realize, the fertiliser containing magnesium Mg content height of preparation, and magnesian content height, and percent hydrolysis height, easily by plant absorbing, intensity is good, is convenient to make the fertile and transportation of BB.
Description
Technical field
The present invention relates to a kind of method for preparing particle magnesium fertilizer.
Background technology
Magnesium is the essential nutritive element of crop, is chlorophyllous integral part, can promote photosynthesis; It is the activator of many enzymes, can promote the absorption of crop, strengthen the Nutrition and Metabolism of phosphorus, to promoting plant disease-resistant, cold-resistantly having a good effect phosphorus, element silicon, magnesium is again modifying agent acid, weakly alkaline soil simultaneously, and raising crop yield, quality are had vital role.
The many forms with magnesiumcarbonate of the form that magnesium exists on earth exist, its burst size is very slow, be difficult to satisfy the needs of plant, have only the magnesium in the soil solution could be by plant absorbing, magnesium oxide be to transform easily and by plant absorbing, the magnesium oxide granulated fertilizer, has enough hardness, can prevent efflorescence in transportation and use, and the diffusion that can in water and soil earth, distribute soon, be beneficial to plant absorbing.
Summary of the invention
The objective of the invention is to propose a kind of easily by preparation method plant absorbing, Mg content height, particle magnesium fertilizer that intensity is good.
Technical solution of the present invention is: light-burning magnesium powder and silica are made granular fertiliser containing magnesium through chemistry and physical reaction, and the composition of each raw material and weight percent are:
Light-burning magnesium powder 53-63%
Silica 10%
Water 25-35%
Citric acid 2%
Concrete preparation process is as follows:
(1) light-burning magnesium powder, silica are mixed by above-mentioned weight percent with water, stir;
(2) 2% citric acid is put into water and stir, make its dissolving, churning time 30 minutes places then that to make soup in 24 hours standby;
(3) in tablets press, the mixture of step (1) is carried out granulation with the soup of step (2) preparation with the form of spraying, the granulation time is 25～40 minutes;
(4) composite grain that will make sieves in roto-sifter, and sieve aperture is 2.0mm～4.0mm, and the diameter that sieves out comes back to granulating working procedure less than the particle of 2.0mm, and diameter is to come into operation as raw material after the above particle of 4.0mm is pulverized;
(5) particle with the 2.0mm～4.0mm interval of sieving out carries out drying in the vibrations dryer, and drying temperature is 180～220 ℃;
(6) detect according to HG/T 3607-2007;
(7) with the qualified product packing, the plastic lining film guarantees airtight airtight.
The invention has the beneficial effects as follows: technology is simple and easy to realize, the fertiliser containing magnesium Mg content height of preparation, and magnesian content height, and percent hydrolysis height, easily by plant absorbing, intensity is good, is convenient to make the fertile and transportation of BB.
