Technical field
The present invention relates to the improvement of organic fertilizer, especially the preparation method of the synergy of sustained release fertilizer, particularly a kind of organic sustained release fertilizer synergist.
Background technology
Learn from searching document, have about the research of sustained release fertilizer report: the 1. patent No.: the patent of 03145577.8 " fertilizer synergist and production method thereof " is that water maintaining synergist outside surface dressing is become compound fertilizer, the characteristics that not only possessed water maintaining synergist, and can also adsorb nitrogen, phosphorus, potassium in the compound fertilizer better, can improve the fertile utilization ratio of compound better, thereby improve crop yield.2. " experimental study of humic acids water-holding slow-release fertilizer " paper of delivering of the Mi Guifang of Agricultural University Of Shanxi, Wang Yuexin, Liu Sensen colleague has disclosed, the fertile maize planting of humic acids water-holding slow-release, can strengthen the maize root system vigor, increase chlorophyll content, improve corn yield.3. " the high-nitrogen slow released agglomeration resistant compound fertilizer technology " that " phosphate fertilizer and multiple fertilizer " September in 2006, the 21st volume 5 phase Shandong Yuan Ze delivered disclosed slow released agglomeration resistant compound fertilizer production.4. to disclose with the humic acids be that the sustained release dosage compound microorganism of urea is made fertile technology etc. to " production technology of organism slow release fertilizer " that " phosphate fertilizer and multiple fertilizer " September in 2007, the 21st volume 5 phase Shandong Wang Huai occasion etc. were delivered, more than all do not relate to the research preparation of sustained release fertilizer synergist.Most in the market slow release fertilizer is based on chemical fertilizer of simple substance, has compound slow release fertilizer synergic not appear in the newspapers, even similar product also not all is to be main organic raw material with animal excrement, the product that has roughly the same, the price virtual height, the Huinong serves undesirable.
Summary of the invention
The objective of the invention is to: the preparation method that a kind of organic sustained release fertilizer synergist is provided, be exactly at the simplification of fertility synergic, by preferred, compound, make the synergistic effect that makes new advances, this synergistic agent on average increases production 18-22% than single fertilising after measured, the plantation of suitable field crop and fruit-bearing forest class.
The object of the present invention is achieved like this: a kind of preparation method of organic sustained release fertilizer synergist, and the organic component of preparing with ratio of weight and number is 25-60 part; The synergy composition is 3-15 part; The amount of solid of slowly-releasing composition is 10-13 part, and amount of liquid is 3.5-9 part; Trace element is 0.5-5 part; Inorganic nutrient is 18-30 part; Additive is the component of 2-7 part, and the method for process weighing, mix, mist projection granulating, oven drying at low temperature makes:
Wherein: (with ratio of weight and number)
Organic component: humic acids 2-5 part; The rubbish that becomes thoroughly decomposed or animal excrement 25-45 part; Residue 2-5 part of monosodium glutamate and sugar;
Synergy composition: zeolite 1-3 part; Flyash 1-5 part; Synergistic agent 2-5 part;
Slowly-releasing composition: wilkinite (solid) 10-13 part; Nitrification inhibitor 0.02-0.1 part (solid); Urease inhibitors 4-8 part (liquid);
Trace element: zinc sulfate 0.1-1 part; Manganous sulfate 0.1-1 part; Borax 0.1-1 part; Copper sulfate 0.1-1 part; Ferrous sulfate 0.1-1 part;
Inorganic nutrient: urea 6-9 part, ammonium phosphate 7-9 part, vitriolate of tartar 5-7 part;
Additive constitutes: gypsum 2-7 part.
The preparation method of above-mentioned fertilizer synergist, the urease inhibitors of slowly-releasing composition is N substituted amide acids, 3-chloro-phenyl-oxaminic acid; Nitrification inhibitor is a thiourea derivative.
The preparation method of above-mentioned fertilizer synergist, mist projection granulating needs to carry out under the spraying of the 4-7% urease inhibitors aqueous solution.
The preparation method of described fertilizer synergist, the temperature of oven drying at low temperature is controlled at below 80 ℃.
The preparation method of described fertilizer synergist, this synergistic agent on average increases production 18-22% than single fertilising after measured, the plantation of suitable field crop and woods fruit.
The reasonableness of technique effect checking inventive concept of the present invention is with scientific:
1, this fertilizer synergist can provide the equilibrated nutritive element to plant.
2, contain beneficial microorganism bacterium and organic matter in this fertilizer synergist, promoted microbial activities in the soil, increased the cementing material that forms Soil structure, improve the calorific value and the temperature of soil.
3, this fertilizer synergist can improve the cationic exchange capacity of soil, strengthens the surge capability of soil, can absorb more potassium, calcium, magnesium, zinc, etc. nutritive element, prevent leaching loss, stablize fertilizer efficiency, the raising soil buffer action.
4, this fertilizer synergist can decompose, transform each seed amino acid, carbohydrate etc. in the soil, promote the synthetic transportation and the accumulation of intravital enzymic activity of plant and material, thereby the raising crop quality, protein, VITAMIN equal size increase crop yield and improve quality of agricultural product.
5, use the anti-adversity ability that this fertilizer synergist can strengthen crop year after year.
6, the raw material of this fertilizer synergist is the rubbish that the mankind or animal produce more than 60%, turns waste into wealth, and alleviates environmental pollution, save energy.
7, this fertilizer synergist has been selected the composition of nitrification inhibitor, urease inhibitors for use, has all effectively controlled volatilization, the release of nitrogenous fertilizer such as urea, has played the effect of indirect guarantor's nitrogen, thereby has improved utilization rate of nitrogen fertilizer.Wilkinite not only can adsorb a large amount of fertilizer, mineral substance, slowly-releasing composition, and improve fertilizer utilization ratio as the vesicular material, also can carry out certain adsorption to nitrogen, nitrogenous fertilizer has also been played the effect of slowly-releasing.
The present invention measures the synergism performance of fertilizer according to GB18877-2002 national standard, HG/T3276-1999, NY525-2002 industry, and the result is as follows:
--the content 2%-8% of-nitrogen 3%-9%, phosphorus 1%-7%, potassium;
---organic amount 10%-20%, humic acid 5%-10%;
--the intensity detection value of-product is on average at 6-15N
---its pH value is 5-7.
The preparation method of the organic sustained release fertilizer synergist that the present invention conceived, scientific formulation is reasonable, has solved the simplification of fertility synergic, by selected compound, has released the synergistic agent of novel slow release fertilizer.But materials such as this each seed amino acid of fertilizer synergist decomposition and inversion, carbohydrate, promote the synthetic transportation and the accumulation of intravital enzymic activity of plant and material, improve crop quality and protein, VITAMIN equal size, effect than single fertilising is on average increased production 18-22%, the plantation of suitable field crop and fruit-bearing forest class shows technical progress.
