Abstract
The present invention is slow released tobacco fertilizer and its production process, and features that special tobacco fertilizer as capsule core is coated with the filming material compounded with inorganic filming material and organic filming material to form fertilizer microcapsules in the size of 3-1000 microns, and the fertilizer microcapsules constitute powdered fertilizer. The filming material accounts for 1-20 wt% of the fertilizer, and consists of inorganic filming material in 20-55 wt% and organic filming material in 45-80 wt%. The slow released tobacco fertilizer is prepared through first mixing special tobacco fertilizer, inorganic filming material and organic filming material in a hot mixer and subsequent dispersing in a cold mixer. The present invention has the beneficial effect of releasing the special tobacco fertilizer slowly to raise the bioavailability.
Description
Technical field
The present invention relates to a kind of fertilizer special for tobacco material, fertilizer special for tobacco that especially a kind of cost is low, slow-releasing good, bioavailability is high and preparation method thereof.
Background technology
Fertilizer utilization ratio is generally on the low side in China's tobacco planting at present, nitrogen about 30～35%, phosphorus is 10～20%, potassium about 35～50%, the tobacco that a large amount of fertilizer that drop into are not grown by this season utilizes or runs off in a large number, has caused the serious wasting of resources and environmental pollution on the one hand, on the other hand because body eutrophication is serious, can cause soil compaction, physico-chemical property descends.Improve the side effect of utilization rate of fertilizer, reduction fertilizer,, improve quality of tobacco, promote China's tobacco production and Economic development to be extremely important stablizing leaf tobacco production.And become the key of leaf tobacco production.
Slowly/controlled releasing fertilizer research starts from the U.S. in mid-term nineteen sixties.Slow release fertilizer is meant a kind of fertilizer that its fertilizer nutrient slowly discharges behind the incorporation of fertilizerin the soil.Controlled release fertilizer is meant a class fertilizer that fertilizer nutrient need be discharged gradually with certain regulatory mechanism with plant growth, have nutrient and discharge the function that absorbs (demand) synchronised with crop, applied once can satisfy the different requirement of crop whole growth phase, can significantly improve utilization rate of fertilizer.At present, the U.S., Japan occupy forward position, the world in the research of slowly/controlled releasing fertilizer, and the U.S. is mainly used in aspects such as golf course, high-quality ornamental plant, gardens, and Japan is mainly used on paddy rice, vegetables, the seeding corn and other crops.But both at home and abroad aspect the research of tobacco slowly/controlled releasing fertilizer seldom, to the research experience of slowly/controlled releasing fertilizer, the microencapsulation technology is effective way and the means of preparation cigarette with slowly/controlled releasing fertilizer according to both at home and abroad.
Although obtained bigger progress in domestic and international at present research, the development and application at other agricultural slow/controlled release fertilizer, but the price of slow/controlled release fertilizer is generally higher, be 3～8 times (Bulk Blending Fertilizer of part controlled release is about 2～5 times) of conventional fertilizer, limited its promotion and application; It is still inconsistent that the rate of release of slow/controlled release fertilizer and pattern and crop absorb the nutrient pattern, and influence factor is not illustrated fully yet; The present domestic slowly/controlled releasing fertilizer that does not still have suitable tobacco special use.
Summary of the invention:
In order to overcome above defective and the deficiency that slowly/controlled releasing fertilizer exists, the invention provides one and grow tobacco slow-release fertilizer dedicatedly, this slow release fertilizer cost increases few, and effect is better.
This special slow release fertilizer that grows tobacco is characterized in that, is the capsule heart with the fertilizer special for tobacco, composite with inorganic film forming material and organic film-forming material is that the film material is wrapped to form fertile micro-capsule, fertile microcapsule diameter is 3～1000 microns, forms powdery product by fertile micro-capsule, and product cut size is in 1000 microns.
Film material weight accounts for 1%～20% of fertilizer gross weight, and wherein inorganic film forming material accounts for and is re-dubbed 20%～55% of mould material, and organic film-forming material accounts for and is re-dubbed 45%～80% of mould material weight.
Inorganic film forming material is zinc oxide, calcium oxide and borax, and their weight accounts for 40%～70%, 5%～15%, 25%～45% of inorganic film forming material weight respectively.
Organic film-forming material is stearic acid, compound ceresine, Microcrystalline Wax, paraffin, its ratio is: stearic acid occupies 25%～60% of machine film forming material, compound ceresine occupies 10%～25% of machine film forming material, Microcrystalline Wax occupies 7%～35% of machine film forming material, and paraffin occupies 5%～23% of machine film forming material.
Fertilizer special for tobacco is a kind of in the following fertilizer or several: ammonium chloride, ammonium sulfate, ammonium phosphate, calcium superphosphate, trimagnesium phosphate, vitriolate of tartar, Repone K.
The production method of this special slow release fertilizer that grows tobacco is characterized in that production stage is as follows:
One, is that 1～200 micron mineral membrane material and organic membrane material mix and place the heating-type mixing tank with particle diameter, under 60～80 ℃ of conditions, mixed 10～20 minutes;
Two, adding particle diameter in the heating-type mixing tank is 1～600 micron fertilizer special for tobacco, mixes 10～20 minutes under 60～80 ℃ of conditions, makes fertile micro-capsule;
Three, change over to again in the cold type mixing tank, under the room temperature condition, disperseed 10～20 minutes, can obtain product.
The invention has the beneficial effects as follows no matter the microencapsulation fertilizer special for tobacco all discharges with the slowly-releasing form, has improved the bioavailability of fertilizer special for tobacco in water or in the different soil of moisture content.
