Abstract
The invention discloses a preparation method of an environmental-friendly fertilizer. In the fertilizer production process, either or both of DCD (dicyandiamide) and DMPP (dimethyl-phenyl-piperazinium) is/are added with the amount of 0.25-10 percent of the material total mass, and if the two are required to be added, the amount can be 1:1; and meanwhile, either or both of PASP (Sodium of Polyaspartic Acid) and a soluble water-retaining admixture is/are added, and the adding amounts are respectively 0.3-0.5 percent and 0.2-0.6 percent of the compound material total mass. The preparation method conforms to the environment-friendly requirement, as well as requirements of the national standard or enterprise standard; either or both of DCD and DMPP, as well as PASP and the soluble water-retaining admixture, is/are added in the fertilizer production process, and palletized after being mixed or directly used, and the prepared environmental-friendly fertilizer can be used as either a base fertilizer or additional fertilizer and can be effectively and slowly released for more than 3 months; the utilization ratio increase of the fertilizer is facilitated and the fertilizer consumption is lowered; and the process is simple, emission of three wastes is not increased and the energy-saving and emission-reducing requirement is satisfied.
Description
Technical field
The invention belongs to fertilizer field, relate in particular to a kind of minimizing soil pollution and chemical fertilizer usage quantity, improve crop yield, increase the preparation method of the environmental friendly fertilizer of crop quality.
Background technology
China's agricultural is occupied main status at present, and wherein in the agriculture production, the use of fertilizer occupies very big ratio in whole agricultural production process.Annual domestic chemical fertilizer usage quantity quantity is big, and on the basis that the chemical fertilizer usage quantity increases, agriculture production environment brings very big problem thereupon.For example: soil compaction, soil acidification, soil foundation structure changes etc. and to be unfavorable for that the factor of plant-growth is following.In order to solve the problem that above-mentioned agricultural is brought, improve utilization rate of fertilizer, reduce fertilizer loss, reduce fertilizer simultaneously and bring harm to edatope, the problem that we need solve mainly is to reduce the chemical fertilizer usage quantity, increases the utilization ratio of chemical fertilizer, improves Soil structure simultaneously.Only improve fertilizer utilization ratio at present, from reducing loss of chemical fertilizer, do not reduce soil compaction and consider.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of preparation method of environmental friendly fertilizer, is intended to solve existing fertilizer preparation technology and can not reduces loss of chemical fertilizer, reduces the problem of soil compaction.
The embodiment of the invention is to realize like this, a kind of preparation method of environmental friendly fertilizer adds one kind or two kinds of DCD and DMPP in the fertiliser production process, addition is the 0.25%-10% of material total mass, when adding two kinds if desired, proportionally be that 1: 1 amount is added; Add PASP and solubility water-holding agent simultaneously and add wherein a kind of or two kinds, addition is respectively 0.3%-0.5% and the 0.2-0.6% of compound material total mass.
Further, this preparation method will adjust fertilizer ratio according to soil and weather condition, for sand soil, at first calculate plant desired nutritional content according to the crop needs, then effective constituent be carried out weighing, be ready to; Weigh DCD and PASP then, nutritive ingredient be put into stirrer stir, slowly add DCD in the restir process, treat DCD add finish after, stirred 20-30 minute, and then slowly add PASP; In adding DCD and PASP process, stirrer can not stop, adding the back that finishes continues to stir 30 minutes, after stirring, the material for the treatment of stirrer stops to stir, emit material, can pack then, or carry out granulation again, material is put into carries out granulation on the tablets press, temperature surpasses 180 degree in granulation process; Brown type soil production stage is sand soil roughly the same, DCD is replaced with DMPP gets final product.
Further, this preparation method's concrete steps are:
According to soil regime and local amblent air temperature environment, select a kind of or two kinds of auxiliary agents among DCD and the DMPP, screen;
With the screening of PASP and solubility water-holding agent, weighing, the amount of taking by weighing is respectively that 0.3%-0.5% and the 0.2-0.6% of compound material quality summation takes by weighing;
The fertilizer material of 1000kg is put into stirrer, stir, slowly add the interpolation according to the 0.25%-10% of by weight of fertilizer then, slowly add or use quantitatively slowly feeding machine that a kind of of DCD or DMPP or two kinds are added in the middle of the fertilizer material;
A kind of in PASP or the water-soluble water-holding agent or two kinds are blended in the middle of the fertilizer;
After treating that fertilizer material and additive mix fully behind the mixing certain hour, through discharge port, raw material is poured out; Finished product is sent into tablets press carry out granulation, or the finished bag direct marketing of packing into.
Further, described prilling temperature can not be above 180 ℃.
The present invention can reduce soil pollution, and the chemical fertilizer usage quantity, improves crop yield, increases crop quality, and in addition, the present invention can also reduce soil acidification, harden.
