Abstract
The invention belongs to the slow-release fertilizer field, and specifically discloses an efficient slow-release fertilizer forguinea grass in dry desert. The fertilizer is characterized by including the following components by weight: soluble starch, polyethylene pyrrolidone, mesoporous silica nanoparticles, micron alum, potassium polyacrylate, white carbon black, plant ash, decay seaweed powder, calcined oyster shell powder, and organic decomposed material. Soluble starch, acrylic acid and polyvinyl pyrrolidone are used as a coating material; materials of different sizes are added in the coating material to enrich the pore size of the coating material, improve the water absorption and water retention performance of the coating material and dynamic slow-release performance of the fertilizer. The fertilizer ensures the use efficiency of nutrients, realizes the control of fertilizer efficiency, promotes the absorption and utilization of different nutrients by forguinea grass, and promotes the efficient cultivation. The double-channel sustained-release coating material with water absorption and water retention effect ensures the orderly release of nutrients, prolongs the degradation time of membrane material, and maintains fertility.
Description
Technical field
The invention belongs to slow release fertilizer field, be specifically related to desert, a kind of nonirrigated farmland sheep's hay high-efficiency sustained-release fertilizer and preparation method.
Background technology
Film-coated and slow release fertilizer has the effect significantly improving utilization rate of fertilizer.But, the most slow-release fertilizers sold in the market are faced with problems, such as: 1, coated fertilizer adopts the non-degradable high molecular polymer of chemosynthesis, and these refractory organics polymer coated fertilizers very easily remain in agricultural soil and cause Soil degradation and serious pollution; 2, coated fertilizer adopts natural polymer degradation material, but slow-release fertilizer selling at exorbitant prices on the one hand prepared by these natural high molecular degradable materials, controlled-release effect is bad on the other hand, along with the degraded of natural macromolecular material can rapid releasing nutrients composition, cause the slow-release fertilizer cycle short, range of application is narrow; 3, existing film-coated and slow release fertilizer can not realize the two-ways regulation of controlled release and slowly-releasing, can not realize the supply of chemical fertilizer Middle nutrition element and crop to the demand basic synchronization of nutrient by dog, can not realize running balance; 4, present slow-release fertilizer is too single to the consideration of external natural condition, for different edatopes, such as paddy field and dry land, acid soil and salt affected soil, high temperature soil and freezing soil etc. do not take into full account, do not consider the water tolerance of coating material, crushing resistance, photosensitivity, pH irritability etc.; 5, the function of existing coating material is more single, usually just sustained-release and controlled release, gives the functions such as coating material water-absorbing-retaining function, antibacterial, deinsectization, weeding, is significant to the development of coating material; 6, production efficiency, service efficiency, the low cost of dressing control release controlled fertilizer will be considered.For release-controlled coated fertilizer Problems existing, efficient, cheap, multi-functional and environmentally friendly coated fertilizer research and development become the prior development direction of domestic and international coated slow release fertilizer research and production application.
The fertilizer efficiency of slow release fertilizer depends on slow-release material, capsule form, market common are and adopt identical or different coated fertilizer realize layering coating and then realize slowly-releasing regulation and control, but can increase material cost and cost of manufacture like this.
Two channels coated fertilizer is built in nanochannel and microchannel, the structure of microchannel and nanochannel can be absorbed and used the space composition caused by means of the structure of material itself and micron/nano material, simply be easy to realize, give slow release fertilizer new function, for the development of slow release fertilizer opens new way simultaneously.
