Description

A kind of slowly-releasing water-maintaining biological organic-inorganic compound fertilizer particle and working method thereof
Technical field
The invention belongs to the biological organic fertilizer production technical field, relate in particular to a kind of slowly-releasing water-maintaining biological organic-inorganic compound fertilizer grain pattern and working method thereof.
Background technology
Along with the continuous development of agriculture prodn, the traditional agriculture of highly energy-consuming, high pollution, low output will be substituted by the ecological agriculture of high yield, low consumption, high-quality and efficient Sustainable development.
Desire to reach this target, it is low at first will to solve the chemical fertilizer nutrient utilization ratio, and the mechanized application degree is poor, repeat fertiliser prodn present situations such as random fertilising, the pollution of slow-release fertilizer coating.The method that addresses this problem is except that the scientific level of balance formula fertilising, raising fertilising; With regard to fertilizer self; Must improve fertilizer structure and formulation, develop applied widely, support that a part utilization ratio height, environmental pollution are low, biodegradable, can improve the soil physics and biological situation, high-quality and efficient new-type fertilizer product.
Slow release fertilizer is that chemical fertilizer is effectively supported a part fertilizer that slowly discharges, from 20th century the seventies begin to occur, research and the category that uses are limited to the slowly-releasing aspect of nitrogen product basically, also are confined to conceptual phase for compound slow release fertilizer and working method thereof.
Aspect the compound slow-release nitrogen fertilizer, adopt two kinds of methods to solve the problem that the nitrogenous fertilizer dissolving is fast, utilization ratio is low usually.The one, reduce the solvability of fertilizer through the method for physics or chemistry; The 2nd, put on one deck coat to fertilizer, one deck waterproof layer is set artificially, prevent that it from directly contacting with soil and dissolving rapidly.Above-mentioned first method and difference of the present invention are bigger.Coating material usable polymers that second method adopted and sulphur dressing, inert material, polymkeric substance and sulphur dressing do not contain water-soluble material owing to poorly soluble, cause the exudative poor of fertilizer, and the rate of disengaging and the farm crop regulation of fertilizer requirement of supporting part are inconsistent; Mostly the carrier of inert material dressing is resin, mechanical wet goods non-degradable material, like improper use, also causes second environmental pollution easily; The degradable coating material is the direction of current development.
Bio-feritlizer, chemical fertilizer, organic fertilizer have constituted the source of plant nutrition together; Effect between the fertilizer of these three kinds of forms is to cooperatively interact but not substitute; This each other replenishing is not only that chemical fertilizer is quantitative to be replenished, and main be on the performance cooperation with replenish.That is to say that fertilizer will be along with science and technology development, progressively develop towards high-effect, compoundization and bioid direction.
