Abstract
The invention relates to a stable controlled-release fertilizer and a production technology thereof. Inhibitor (nitrification inhibitors and urease inhibitors) for stable fertilizers and controlled-release agents (attapulgite, polyacrylamide and aluminum ferric chloride) for controlled-release fertilizers are scientifically compatible and organically combined, so that the inhibitors and the controlled-release agents play a synergistic effect. Hydrolysis and conversion of fertilizer nutrients are inhibited in the early period, and the nutrient loss is reduced through net capturing adsorption in the later period, so that a controlled-release effect in the whole process is achieved. The stable controlled-release fertilizer has the advantages of simple and convenient technology and low cost, and is suitable for national conditions and agricultural conditions, so that comprehensive benefits of yield increase, fertilizer saving and labor saving are achieved agriculturally. Moreover, the environmental pollution can be reduced, the resources are saved, and the environment-friendly and resource-saving basic state policy of zero fertilizer yield increase is met.
Description
Affiliated field
The invention belongs to slowly-releasing sustained-release fertilizer material technical field, be specially a kind of stability lost control fertilizer and production technique thereof.
Technical background
Fertilizer occupies critical role in agriculture production.China is fertiliser production and uses big country, and its output and consumption are first place, the world.But amount of application is higher, utilization ratio is on the low side, not only wastes resource but also pollute environment, and the resource-conserving advocated with China and environmentally friendly industry require to differ greatly.Relevant department of current China also been proposed the plan of chemical fertilizer zero growth rate, and namely before the year two thousand twenty, fertilizer production no longer increases, and utilization ratio improves one percentage point every year.40% is brought up to, for this reason except will improving to some extent and break through in fertilizer practice from current 35%.Development of new, efficiently slowly-releasing sustained-release fertilizer material are the problems of important, the arduous and task of top priority of in face of we fertilizer worker one of pendulum.
The sustained-controll-release fertiliser kind of the production of current China and use is a lot, mainly contains coating, dressing, coating class fertilizer; Urea aldehydes fertilizer; Add the stable fertilizer of inhibitor and add the sustained-release fertilizer material etc. of controlled release agent.Wherein coating class fertilizer and urea aldehydes fertilizer complex process, cost is higher, applies and acquires a certain degree of difficulty; Stable fertilizer can only suppress the hydrolysis of the nitrogenous fertilizer such as urea, conversion rate and process; Sustained-release fertilizer material can only be controlled mistake (net is caught, adsorb) and discharge the fertilizer nutrient be dissolved in soil, and controlled release agent large usage quantity (generally accounting for about 10% of fertilizer), be difficult to the composite fertilizer producing high-content.
Summary of the invention
For the shortcoming and defect part of the various sustained-controll-release fertiliser of appeal, the present invention proposes a kind of stability lost control fertilizer and production technique thereof, is the controlled release agent scientific compatibility by the stablizer of stable fertilizer and sustained-release fertilizer material, organically combines, makes it act synergistically.First inhibitor works, the hydrolysis of the nitrogenous fertilizer such as urease inhibiting effective and conversion process, adds controlled release agent and catches applying the nutritive element major part net of fertilizer through dissolving and discharge and be adsorbed in crop rhizosphere soils.Like this by suppressing and control to lose to organically combine, can double raising utilization rate of fertilizer and extend fertilizer efficiency period, make agricultural reach volume increase, save comprehensive benefit that is fertile and saving of labor, there is the great social benefit and good environmental ecological benefit that reduce environmental pollution and saving resource simultaneously.
Stability lost control fertilizer, is characterized in that: this fertilizer is by following component, forms by weight percentage:
Inhibitor: 0.1 ~ 0.5%,
Controlled release agent: 3 ~ 15%,
Fertilizer: 84.5 ~ 96.9%.
A production technique for stability lost control fertilizer described above, is characterized in that: wherein inhibitor is nitrification inhibitor and urease inhibitor; Nitrification inhibitor is Dyhard RU 100 or nitrogen-pyridine; Urease inhibitor is thiophosphoryl triamide or Resorcinol; Controlled release agent is: one or more in attapulgite, polyacrylamide and aluminium chloride ferrum; Fertilizer is the composite fertilizer of nitrogen, phosphorus, potassium composition; Then be prepared according to above-mentioned proportion of composing.
The production technique of described stability lost control fertilizer, is characterized in that: for being joined respectively in mixing machine by above-mentioned raw material, fully mix, then through granulation, oven dry, screening, metering, packaging, make stability lost control compound fertilizer.
Advantage and effect
Innovative point of the present invention and substantial advance are, by inhibitor and controlled release agent scientific compatibility, synergy, reaches the effect of 1+1 > 2.First hydrolysis and the conversion of fertilizer nutrient is suppressed, then the loss of absorption nutrients loss caught by net, reach omnidistance slowly-releasing, control mistake effect, improve fertile utilization ratio to greatest extent and extend fertilizer efficiency period, the comprehensive benefit of the fertile and saving of labor of the volume increase making agriculture production reach larger, joint.Reduce environmental pollution simultaneously more obviously and economize on resources, reaching environmentally friendly, the state basic policy requirement of resource-conserving and chemical fertilizer zero growth rate.
