Abstract
The invention discloses an environment-friendly coated slow release fertilizer preventing pest and disease damage and a preparation method thereof. The environment-friendly coated slow release fertilizer is characterized by being prepared from the following raw materials in parts by weight: 0.5-1.5 parts of diallyl disulfide, 10-20 parts of acrylic acid, 30-50 parts of sodium alginate solution, 3-5 parts of donkey bone powder, 1-2 parts of ammonium persulfate, 3-6 parts of N,N-methylene bisacrylamide, 0.5-1 part of diallyl trisulfide, 15-25 parts of polyvinyl alcohol, 3-5 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. In the invention, by adding a water retaining agent into crosslinking liquid and spraying on the fertilizer core, the defect that a water retaining agent easily falls when the water retaining agent is directly adhered to the fertilizer core is overcome, and the water retaining effect of the fertilizer is remarkable; meanwhile, the crosslinking liquid also can realize an aim of enhancing the water resistance of the fertilizer and is easily biodegradable; and through the compounding of the raw materials, the pest and disease damage of crops can be effectively prevented, and the soil is purified.
Description
Technical field
The present invention relates to a kind of slow-release fertilizer, and in particular to a kind of system of the environmentally friendly film-coated and slow release fertilizer for preventing pest and disease damage
Preparation 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
Thinking based on more than, difficult for drop-off the invention provides a kind of water-loss reducer, coating good waterproof performance, slow release effect is excellent
