A kind of slow-release compound fertilizer and its production technology rich in several mineral materialsTechnical field
The present invention relates to fertilizer field, and in particular to a kind of slow-release compound fertilizer and one kind rich in several mineral materials are rich inThe production technology of the slow-release compound fertilizer of several mineral materials.
Background technology
Compound fertilizer refers to the chemical fertilizer containing two or more nutrient, and composite fertilizer has nutrient content high, secondaryComposition is few and the advantages of good physical behavior, for balance fertilizing, improves utilization rate of fertilizer, promoting the stable high yield of crop has tenDivide important effect.But it also has some shortcomings, such as its nutrients ratio is always fixed, and different soils, Different CropRequired nutrient species, quantity and ratio is various.Therefore, preferably carry out surveying soil using preceding, understand field soilQuality and nutrition condition, further note also that with straight fertilizer compounding application, can just obtain more preferable effect.
In order to improve the utilization rate of composite fertilizer, slow-release compound fertilizer has been derived, wherein, " sustained release " refers to chemical substance nutrientRate of release is changed into the rate of release of plant effective state nutrient after being manured into soil much smaller than Quick-dissolving fertilizer.But it is of today slowThe content of mineral substances that facilitation is played to crop growth contained in composite fertilizer is released less, largely using certain several chemistry memberElement, over time, destroys the ecological balance of soil, causes plant growth slower, easily grow germ.
Chinese Patent Application No. is that CN201210074040.1 discloses a kind of preparation method of slow-release compound fertilizer, this methodIt is useless to livestock culture using adsorbents such as blast furnace slag, natural zeolite, coke, NACFs using livestock culture waste water as raw materialThe plant nutrient ingredients such as N, P, K in water are adsorbed, through drying after adsorbent adsorption saturation, are crushed, dispensing, are made after coatingSlow-release compound fertilizer.The preparation technology of this kind of composite fertilizer is simple, be easily achieved, cost is relatively low, and can mitigate fowl and livestock farm and supportThe pressure of waste water subsequent treatment is grown, with significant environment, economic and social benefit, but is comprised only in this kind of composite fertilizer inorganicThe elements such as mineral matter, not organic material, the one side feature of environmental protection is poor, and cost is higher, on the other hand, to the rush of crop growthEnter effect also weaker.
The content of the invention
Problem to be solved by this invention is to provide the delaying rich in several mineral materials that a kind of scrappage is low, difficulty of processing is lowRelease the production technology of composite fertilizer.
To achieve these goals, the technical scheme taken of the present invention is：What is provided is a kind of rich in several mineral materialsSlow-release compound fertilizer, includes the raw material of following parts by weight：Attapulgite clay 55-70, agricultural crop straw 10-15, feces of livestock and poultry 10-15th, edible fungi residue 5-10, soil conditioner 4-8, the ratio of the agricultural crop straw and feces of livestock and poultry is 1:1.
It is preferred that, the composite fertilizer includes the raw material of following parts by weight：Attapulgite clay 60, agricultural crop straw 15, livestock and poultryExcrement 15, edible fungi residue 5, soil conditioner 5.
It is preferred that, the agricultural crop straw and feces of livestock and poultry are handled by fermentation.
A kind of production technology of the slow-release compound fertilizer rich in several mineral materials, comprises the following steps：
(1) agricultural crop straw, feces of livestock and poultry and edible fungi residue are put into fermentation tank by proportioning first and sent outFerment becomes thoroughly decomposed 6-10 days, then by the raw material after fermentation by crushing, sieving, and adds a certain proportion of biological function bacterium, passes throughMixer mix fully；
(2) after after the raw material mixing fully in step (1), it is sent in comminutor and is granulated, it is past while granulationSodium alginate powder is added in comminutor, certain density calcium chloride water is sprayed after the completion of granulation to it, to sodium alginateIt is crosslinked, the raw material after crosslinking is finally placed in low temperature drying in moist closet, cooling,；
(3) to the compound fertilizer granules sprayed biological microbial inoculum after cooling, coating, the qualified rear metering packing of final inspection, productStorage.
It is preferred that, total amount and agricultural crop straw, feces of livestock and poultry and the edible fungi residue total amount of the biological function bacteriumMass ratio is 1:200, the biological function bacterium bag includes bacillus licheniformis, bacillusmusilaginosiengineering and Streptomyces jingyangensis.
It is preferred that, the mass ratio of the bacillus licheniformis, bacillusmusilaginosiengineering and Streptomyces jingyangensis is 1:1:1.
It is preferred that, the concentration of calcium chloride water is 8% in the step (2).
Beneficial effects of the present invention：
(1) the preferred attapulgite clay of composite fertilizer of the invention is as main component, its rich in silicon, potassium, calcium, sulphur, iron, magnesium,The various trace elements of manganese, iodine, selenium etc. 20, it is especially rare using iodine, selenium very, to can be rated as the world, meanwhile, its adsorptivity is very strong, suctionAttached various elements sustained-release and controlled release, reaches the effects such as fertilizer conservation section is fertile.
(2) be also added into a certain amount of organic material in composite fertilizer of the invention, it is fermented become thoroughly decomposed after agricultural crop straw,Feces of livestock and poultry and edible fungi residue can provide the nutrient of abundance for production estimation, while soil can be nursed one's health, help to changeKind, optimization soil constituent, keeps a good soil ecosystem, the pollution to environment is few, and environmental protection and energy saving are with low cost；
(3) sodium alginate after being crosslinked in the present invention is as fertilizer internal layer coating, the peplos for coordinating bacteria agent to make,Two layers of capsule structure is formed, slow release effect is more preferable.
(4) the preferred bacillus licheniformis of biological function bacterium, bacillusmusilaginosiengineering and the Streptomyces jingyangensis in the present invention,Wherein bacillus licheniformis has effect that is disease-resistant, killing harmful bacteria；Bacillusmusilaginosiengineering has potassium decomposing, discharges Leaching Properties of Soluble PhosphorusThe effect of potassium element, Streptomyces jingyangensis has enhancing soil fertility, stimulates the ability of plant growth.
(5) method technique of the invention is simple, simple operation, efficiency high.
