Abstract
The invention discloses a preparation method of a controlled-release fertilizer for peanut planting. The method comprises three steps including preparation of fertilizer cores, preparation of a coating and preparation of a finished product; the fertilizer cores are prepared through reasonable fertilizer matching according to growth demands of peanuts; the coating prepared from degradable plastics and a film modifier is selected, on one hand, the sources of the plastics are wide, and the cost is lower; on the other hand, controlled release of the fertilizer is realized through step-by-step decomposition; the added film modifier can regulate the speed of controlled release to accord with the peanut growth cycle; the fertilizer cores are coated with multiple coatings by the aid of an adhesive, and a good controlled release effect is realized.
Description
Technical field
The present invention relates to Controlled Release Fertilizer preparing technical field, be specifically related to the preparation method of a kind of peanut cultivation Controlled Release Fertilizer.
Background technology
Semen arachidis hypogaeae is legume, rich in fat and protein, of many uses, has higher status in national economy,
Current substantial amounts of Semen arachidis hypogaeae is used to oil expression, Oleum Arachidis hypogaeae semen, and color and luster is limpid, fragrant, and flavour is good to eat, is that one is easier digestion
Edible oil.Oleum Arachidis hypogaeae semen is containing unsaturated fatty acid more than 80% (wherein containing oleic acid 41.2%, linoleic acid 37.6%).The most also contain
There are palmitic acid, the satisfied fatty acid such as stearic acid and arachidic acid 19.9%.The Fatty acid compositions of Oleum Arachidis hypogaeae semen is reasonable, it is easy to people
Body is digested and assimilated.
Using suitable fertilizer will be the important channel improving peanut yield.But it is specifically designed to all kinds of compound of Semen arachidis hypogaeae at present
In (mixing) fertilizer, there is following problem: fertile the phase is short, utilization rate of fertilizer is low；Single inorganic fertilizer causes soil compaction；Single
Fertilizer nutrient is low, fertilizer efficiency is poor；In general fertilizers and do not contain raising crop yield and the middle trace element of quality or middle trace
The problems such as element is the most comprehensive.
Chinese invention patent application number: CN201310194337.6, invention entitled: one cultivate peanut long-acting special biology delay
Releasing fertilizer and preparation method thereof, disclose a kind of Long-term biological slow-release fertilizer special for peanut and preparation method thereof, it is with ureaformaldehyde peplos
Carbamide, urea coated nitragin compositions, potassium sulfate, calcium magnesium phosphate, MAP, humic acids, ferrous sulfate, zinc sulfate,
EDTA Chelated Manganese, Borax, molybdic acid are raw material, and blended stirring 6-8 minute fully mixes, and then measure, pack and i.e. obtain into
Product.But this invention preparation method is relatively complicated, and production cost is higher, industrialized production is difficult to popularization and application.Therefore, produce
Go out low cost, meet the Controlled Release Fertilizer of peanut growth demand, slow-release fertilizer be still today research and development emphasis.
Summary of the invention
For solving above-mentioned technical problem, the invention provides the preparation method of a kind of peanut cultivation Controlled Release Fertilizer.
The present invention is achieved by the following technical programs:
A kind of preparation method of peanut cultivation Controlled Release Fertilizer, the method comprises the following steps:
Prepared by a, fertilizer core: mixed after carbamide, potassium dihydrogen phosphate, calcium magnesium phosphate, multielement compound micro fertilizer, clay pulverizing respectively
Even, spray mineral oil after low temperature pelletize, dry screening, prepare after cooling；
Prepared by b, coating: after degradation plastic, membrane wrapping modified dose of difference pulverizing, mixing prepares coating；
Prepared by c, finished product: spray binding agent at fertilizer wicking surface, then spray the coating of fertiliser granulates weight 0.5-1%,
Spray binding agent again, then spray the coating of fertiliser granulates weight 0.8-1.2%, then spray binding agent, then spray fertiliser granulates weight
The coating of amount 1-2%, cooling prepares finished product.
In described step a, the weight portion of fertilizer core raw material is: carbamide 10-25 part, potassium dihydrogen phosphate 5-8 part, calcium magnesium phosphate
10-15 part, multielement compound micro fertilizer 1-3 part, clay 2-5 part, mineral oil 5-10 part.
In described step a, multielement compound micro fertilizer is made up of iron sulfate, zinc sulfate, Borax, ammonium molybdate, sulfurous acid selenium.
In described step a, after pulverizing, size is 60-100 mesh.
In described step b, degradation plastic, the weight ratio of membrane wrapping modified dose are 3:0.2-0.8.
In described step b, after pulverizing, size is 100-150 mesh.
In described step b membrane wrapping modified dose be starch, coconut husk, mineral powder one or more.
In described step c, binding agent is Modified-Starch Binder.
In described step c, finished product grain size is 3-8mm.
The beneficial effects of the present invention is: having the advantage that of the peanut cultivation Controlled Release Fertilizer using the present invention to prepare
Growth demand according to Semen arachidis hypogaeae fertilizer of reasonably arranging in pairs or groups prepares fertilizer core, meet its to nitrogenous fertilizer, potash fertilizer, phosphate fertilizer etc. while,
Micro-fertilizer therein can improve micronutrient levels in Semen arachidis hypogaeae, more has market value；After fertilizer core pelletize, oiling can make fertilizer core
Smooth outer surface, consolidation, densification, make nutrient release rate slow down, and improves the peplos controlled-release effect to nutrient；Select degradable
Plastics and the membrane wrapping modified dose of coating made, one is that degradation plastic source is wide, and price is relatively low, and two is by its decomposition progressively
Achieving the controlled release of fertilizer, membrane wrapping modified dose of addition can regulate the speed of controlled release, to meet the peanut growth cycle；And wrap
Film modifier can induce coating aging, degraded, will not remain for a long time in soil, environmental protection；Finally by binding agent at fertilizer
Cover, on material core, the controlled-release effect that multiple coatings has reached good.The present invention has good controlled-release effect, and use can make Semen arachidis hypogaeae
Yield increases, and improves quality, is conducive to increasing the income at plantation family, has application value.
