Description
Technical field
The present invention relates to a kind of microcapsule organic chemical fertilizer, particularly relate to a kind of preparation method of microcapsule organic chemical fertilizer.
Background technology
Organic fertilizer is meant and contains organic substance, and multiple inorganic nutrients of farm crop and organic nutrient can be provided, one type of fertilizer can fostering and apply fertilizer again and improve the soil.Wherein the overwhelming majority is gathered materials on the spot for farmers', long-pending voluntarily the system.The application of organic fertilizers material be thousands of year over the essential measure of Chinese traditional agriculture development, although nearly one period fertilizer amount constantly increase, under the situation of current pay attention to day by day environment for human survival, organic fertilizer receives people's attention once again.Organic fertilizer relies on the less soil hydro-thermal cycle dynamics property variation of daily amplitude; Create a good environment to microbial activities; Make it form the high soil ulmin of preserve moisture and fertility power, thereby improve fertility and the crop yield and the quality of soil smoothly through the humify stage.
Organic fertilizer is the recycling of nutrient in the agricultural and utilizes part again that therefore, along with the increase of applying quantity of chemical fertilizer and increasing of crop harvesting thing, the quantity of organic fertilizer also increases to some extent.Though in recent years because the rolling up of chemical fertilizer input; The shared ratio of the nutrient of organic fertilizer input significantly reduces; But still account for 36.7% of the total input amount of total nutrient; Organic fertilizer also can provide organotrophy compositions such as a considerable amount of middle amounts, trace element and amino acid, nucleic acid, sugar, VITAMINs except that containing nitrogen, phosphorus, potassium and organic carbon nutrient.Organic fertilizer is because wide material sources, so kind is a lot, and below generally can dividing several types: the one, fecaluria is fertile, comprises human excrement, livestock waste, brid guano etc.The 2nd, fertile type of stack retting comprises compost, makes compost, straw-returning and biogas ferment fertilizer etc. that the compost that various raw materials are processed all contains nitrogen, phosphorus, potassium and the trace element of crop needs, helps fertilizing soil child; Stalk accounts for about 50% of crop biomass, is the organic manure resource that one type of quantity is extremely abundant, can directly utilize.The 3rd, the cake fertilizer class comprises soybean cake, peanut cake, dish cake and tea seed cake etc.The 4th, the peat class is claimed the peat composed of rotten mosses again.Contain more humic acids, can be used for making humic acid fertilizers such as ammonium humate, nitro-humic acid ammonium, Sodium salts humic acids.The 5th, the earth class comprises pond sludge, lake mud, river silt, wall soil, hole soil etc.The 6th, cities and towns waste class comprises sewage, worker's sewage, slaughterhouse waste, rubbish and various organic wastes etc.The 7th, the miscellaneous fertilizers class comprises scurf, hoof tips, fertile, the silkworm faeces in sea.
Microcapsule can be protected the material protected from environmental influences; Shielding taste, color, smell change substance weight, volume, state or surface property, isolate activeconstituents; Reduce volatility and toxicity; Control multiple effects such as sustainable release, from nineteen thirties so far, microcapsule have been widely used in a plurality of fields such as medical science, food, agricultural chemicals, makeup, metal cutting, coating, printing ink, additive.The preparation of microcapsule at first is that liquid, solid or gas core material (core) are divided carefully, is core with these droplets (grain) then, and polymer film-forming material (wall material) is deposited above that, and coating forms thin film, and capsule heart droplet (grain) is coated.This process is called micro encapsulation.Microencapsulation Method is a lot; But the method that does not also have a kind of standard can be used in the production of all microcapsule; Though, be to describe some concrete micro encapsulation processes or introduce the application of microcapsulary mostly in a certain field so the document of relevant microcapsule aspect is a lot.
Microcapsule is the highest a kind of of technology content in the current pesticides new formulation; Though the share that it occupies is also very little, far do not arrange the status of the main formulation of agricultural chemicals in pesticide preparation market; But in view of it has many advantage and functions that has glamour; Cause people's extensive concern day by day, people particularly on the horizon constantly strengthen for the consciousness of safety, environmental ecology and Sustainable development, and many advantages of microcapsule certainly will will become the important development direction of pesticide preparation.
