Abstract
The invention discloses an environment-friendly coated slow release fertilizer containing biological bacteria and a preparation method thereof. The fertilizer is prepared from, by weight, 1-2 parts of yellow humic acid potassium, 10-20 parts of acrylic acid, 30-50 parts of sodium alginate solution, 0.5-1 part of biological fertilizer powder, 1-2 parts of ammonium peroxydisulfate, 3-6 parts of N,N'-methylenebis, 3-5 parts of active straw ash, 15-25 parts of poval, 4-7 parts of starch, 25-35 parts of urea, 8-15 parts of potassium hydrogen phosphate , 40-50 parts of calcium chloride solution and 50-100 parts of distilled water. The preparation method comprises the steps of adding a water retention agent into crosslinked fluid, and spraying the solution on a fertilizer inner core. The shortcoming that the water retention agent is prone to falling when directly adhering to the fertilizer inner core is overcome. The water retention effect of the fertilizer is obvious. At the same time, the crosslinked fluid can exert the function of increasing the water resistance of the fertilizer, at the same time, the environment-friendly coated slow release fertilizer is biologically degradable and environment-friendly, the introduction of biological bacteria can degenerate pesticide and fertilizer damage, and degrade heavy metal.
Description
Technical field
The present invention relates to a kind of slow-release fertilizer, and in particular to a kind of preparation of the environmentally friendly film-coated and slow release fertilizer containing biological bacteria
Method.
Technical background
It with granular chemical fertilizer is heart core that coating slowly/controlled releasing fertilizer is, surface coats one layer of inorganic matter or organic of slightly water-soluble
High molecular polymer, the material can change the release characteristics of chemical fertilizer nutrient, extension or control fertilizer nutrient release, make its nutrient
The new-type fertilizer that release is mutually coordinated with the regulation of fertilizer requirement of crop.The development of this kind of fertilizer is raising utilization rate of fertilizer, mitigates environment
The modern agriculture that pollution, development save labor proposes new thinking.Therefore, fertilizer science, agrology, environmental science, chemistry etc.
The researcher of subject sets foot in the field one after another, and achieves large quantities of valuable achievements in research.At present, oneself applies and just grinds
The slow/controlled release material studied carefully can be divided into inorganic (ore deposit) thing powder, organic high molecular polymer, environmentally friendly material (organic-inorganic
Compound) three major types.
Ni Bo stands in its Master dissertation《The preparation of environmental friend type multifunction sustained-controll-release fertiliser and performance study》
In, a kind of the fertilizer of retaining water and releasing nutrients slowly is prepared for using sodium alginate and polyacrylic acid, but it is easy to fall off also to there is water-loss reducer, and coating is prevented
It is aqueous to have much room for improvement, and slow release it is not good enough the problems such as.
The content of the invention
