Abstract
A kind of used for aquiculture solid suspension-applicating fertilizer is to be capsule-core with general chemical fertilizer, and high polymer is the capsule clothing, and banana oil is that solvent and magnesium silicate, expanded perlite are the encapsulate of auxiliary material.Earlier capsule dress material and auxiliary material molten (mixing) are gone in the solvent, add the capsule-core material then and carry out packing, reenter the mould drying and moulding.It is suspended near the aquaculture thing, can be in the long duration slow release fertilizer, help that material culture absorbs, growth, can improve fertilizer efficiency, save fertilizer, also favourable protection environment.
Description
The invention belongs to the aquaculture special-purpose fertilizer material, particularly slowly-releasing suspension-applicating fertilizer and manufacture method thereof.
Along with the development of society, water plants (comprising fresh water and mariculture) provides the increasing food and the raw material of industry to the mankind.Yet the fertilizer that contains in the water is less, brings tangible difficulty for the development of propagating artificially, so artificially applying fertilizer is important measures of expanding culturing area, promoting to produce, improve the quality and increase output.Because particular environment; water surface fertilising has very big difference with land fertilising; the method fertilising of spray, broadcast application material particle or the aqueous solution is generally adopted in aquaculture (as sea-tangle, opotism etc.) at present; also useful in recent years suspension strap aperture fills the method for the plastic sack of chemical fertilizer and gives marine crop fertilization; yet there is big defective in this method: (1) chemical fertilizer is all instant in water; it is instant to apply in the water moment; flowed by stormy waves and water layer then spreads rapidly; arrive and culture the crop place seldom; the most of loss caused a large amount of wastes.As laminaria culture is 1.2 ten thousand strain/mus, and year need be executed sulphur ammonium 55.8kg, and actual fertilizing amount reaches 150kg; (2) since chemical fertilizer run off rapidly, crop is provided with fertilizer in the vicinity and in time supplies its absorption, this for plant growing unfavorable-promptly can not be long-acting; (3) pollution, particularly nitrogen oxide that excess is applied fertilizer and loss causes waters and atmosphere in a large number enters stratosphere and can damage the ozone layer its harm seriously.
The purpose of this invention is to provide a kind of solid fertilizer novel form of making by chemical fertilizer and macromolecular material, it can be hung on and culture near the crop in the water, in the long duration, discharge chemical fertilizer lentamente and closely absorb, not only help plant growth but also improve utilization rate of fertilizer for plant.
The present invention is from the microcapsule technology of contemporary extensive use, according to the needs of the specific environment for use of aquaculture, uses macromolecular material and fertilizer and makes block encapsulate.This encapsulate hangingly in the water after, the continuous infiltration of water with the dissolving of the fertilizer in the capsule, under its concentration gradient and osmotic pressure effect, is successively oozed and is worn cyst wall gradually, and the fertilizer molecule is diffused in the outer water of capsule gradually.Because the continuous infiltration of hydrone, constantly dissolving, dissolved fertilizer molecule is counter to be worn heavy cyst wall and just is diffused in the outer water of capsule piece, has delayed dissolving, has also delayed release, has reached the slowly-releasing purpose, has also had long-acting function.
The capsule clothing material that the present invention uses is macromolecular materials such as polystyrene, poly-urine aldehyde, polyolefin and polyurethane; Solvent is general banana oil; Fertilizer is water-soluble general chemical fertilizer, as ammonium nitrate, sulphur ammonium, carbon ammonium, urea etc.; Powder such as magnesium silicate, expanded perlite is used as auxiliary material.The present invention uses composition of raw materials (weight) to be:
Fertilizer 45.0～61.0%
High molecular polymer 5.0～15.0%
Banana oil 15.0～25.0%
Magnesium silicate powder 13.0～16.0%
Swelling perlite powder 0.0～2.0%
Its preparation method is:
(1) glue preparation: under agitation chippy high molecular polymer, magnesium silicate powder, swelling perlite powder are added in the banana oil by prescription, make its dissolving, mix.
(2) glue packing: under agitation fertilizer (powdery) is added in the glue that had been prepared into already by prescription, fully mix, form uniformly covering continuously to reach the fertiliser granulates surface by continuous stirring.
(3) form: the uniform packing glue of above-mentioned preparation is fed into preprepared has in the saturating body plastic sheath of mesh formula (mould), place the moulding of drying box (device) dry solidification.
The block packing fertilizer of this moulding can be suspended in the water in culturing near the crop group, does to make it maintain certain density fertilizer in a long time near the object owing to the dissolving gradually of water constantly discharges fertilizer to be diffused in, and is beneficial to plant growth.The rate of release of this spacetabs type fertilizer can the high polymer amount achieves the goal in the prescription with adjusting.Thisly outstanding execute mode and also be suitable for breed such as shellfish in the water, algae, fish, shrimp, also can be used for culturing dispenser, medicine oxygenation etc.Packing is finished using, and the empty pocket shell is recyclable, uses as the capsule material once more after crushed.
Characteristics of the present invention are: (1) can effectively apply fertilizer to aquaculture.Can near breed ground, cause the subenvironment of certain fertilizer concentration, material culture can be grown fast.(2) save fertilizer in a large number.(3) help environmental protection.
Example 1
The fertile composition of raw materials of LERF-I type is:
Urea 60.3%
Polystyrene 5.2%
Banana oil 20.7%
Magnesium silicate powder 13.8%
Polystyrene powder, magnesium silicate powder are added in the banana oil under stirring, constantly stir and make its dissolving, mixing, urea (granular) is added wherein, after stirring, be fed into (garden shape) in the mould of plastics that plastic gauze is housed, place natural seasoning curing under the ventilated environment, every contains fertile amount is 250g, and fertilizer efficiency period is 7～9 days.
Example 2
LERF-II type fertilizer formula is:
Urea 58.3%
Polystyrene 8.3%
Banana oil 20.0%
Magnesium silicate powder 13.4%
Preparation method such as example I, fertilizer efficiency are 16～18 days.
Example 3
Ammonium nitrate 50.0%
Polystyrene 11.5%
Banana oil 23.1%
Magnesium silicate powder 15.0%
Swelling perlite powder 0.4%
Method for making such as example 1, fertilizer efficiency are 8～10 days.
Claims (4)
1, a kind of used for aquiculture suspension-applicating fertilizer, it is fertile in the solid encapsulate to it is characterized by this type, is to be made of fertilizer, high molecular polymer, banana oil, magnesium silicate, expanded perlite.
