Description
Technical field
The invention belongs to slow release fertilizer field, be specifically related to high-efficiency sustained-release fertilizer and the preparation method of a kind of coastal saline soil ground Herba Astragali Melilotoidis (Herba Astragali Sinici).
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.
Coastal beach soil belongs to marine solonchak type, due to the impact for a long time by oceanic tide, salinification effect causes that soil salt content is higher, the soil body grow not obvious, physicochemical character is poor, fertility level is low, and beach area is also with certain speed increment, simultaneously arable area successively decrease year by year and the something lost day by day of Freshwater resources weary, the exploitation of coastal saline soil more and more receive the concern of people.
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.
How the High-efficient Production of herbage and green manure plant is the problem always received much concern, and it is good problem to study that the High-efficient Production realizing coastal saline soil herbage and green manure plant on the ground by slow release fertilizer realizes that beach Efficient Development saline land utilizes.
