Description
Technical field
The present invention relates to a kind of moderate-element composite fertilizer and manufacture method thereof, belong to agrochemical technical field.
Background technology
China is vast in territory, forming process and the chemical composition thereof of soil in all parts of the country vary, along with the change of farming time, cropping system and temperature thereof, humidity, kind, there is significantly change in the chemical composition of its soil, effective constituent, although agricultural sector of China had carried out in recent years survey soil formula etc.-serial technological means, but large owing to putting few face, still can not entirely accurate ground reflect soil truth, thus cause having occurred " macroelement (N, P, K) is loss (cross and execute); Trace element is spraying; Moderate-element is out in the cold " phenomenon; Should be understood that, the existing large quantities of scholar of China is being engaged in the research of moderate-element, particularly the researcher of Henan Province's the earth physics Institute---the father Cai Delong of siliceous fertilizer just introduced siliceous fertilizer manufacturing technology from Japanese system before 20 right years, but China particularly the southern paddy rice liking silicon apply and not yet reach gratifying result.At present, the multiple institution of scientific research in the whole nation and a collection of science researcher, just how to obtain can balance nitrogen, phosphorus, potassium absorption, reduce the loss of potassium in soil, phosphorus of living is for phosphorus and reduce heavy metal in soil to the moderate-element composite fertilizer of pollution of agricultural products as great brainstorm subject.
Summary of the invention
The object of the invention is to: overcome the defect in above-mentioned existing chemical fertilizer application, provide
oneplant moderate-element composite fertilizer and the manufacture method thereof of energy increasing yield and improving quality, in order to the phosphorus in activating soil, silicon, the absorption of the nitrogen simultaneously in balanced soil, phosphorus, potassium, supplement moderate-element calcium, magnesium, silicon, particularly suitably promote the pH value of soil, thus alleviate the pollution of heavy metal in soil to agricultural-food.
For solving its technical problem, the present inventor is through concentrating on studies for many years, carry out repeatedly balancing each element proportioning and solvability in composite fertilizer, the experiment of the katalysis of reinforced micro-element, combine the experimental data in Guangdong, Guangxi, Yunnan, Fujian, Hunan, Hubei, Jiangxi simultaneously, and implement more than 100 mu pilot scales in flakes in July, 2014, achieve gratifying pilot-scale experiment through contrast test; Experimentally the data obtained, in conjunction with the reality of the few phosphorus of China's soil potassium deficiency, particularly recent two decades disorderly digs super row causes great heavy metal contamination situation to soil, develop a kind of technical scheme of moderate-element composite fertilizer of energy increasing yield and improving quality, the weight percent of this each raw material of moderate-element composite fertilizer is as follows:
1、 SiO
2 32%~42%;
2、 CaO 30%~40%;
3、 MgO 20%~30%;
4、 SO
32%~4%。
Preferably, described SiO
2content be 34% ~ 40%;
Preferably, the content of described CaO is 32% ~ 38%;
Preferably, the content of described MgO is 22% ~ 28%;
Preferably, described SO
3content be 2.5% ~ 3.5%.
The moderate-element composite fertilizer of this energy increasing yield and improving quality, the source of its material is natural mineral or pure-oxide:
1, SiO
2: be silica or wollastonite;
2, CaO: be Wingdale or rhombspar;
3, MgO: be rhombspar, serpentine, sepiolite or talcum;
4, SO
3: be anhydrite, desulfurated plaster, phosphogypsum or fluorgypsum.
In a word, starting material are selected first to require, as far as possible not containing harmful heavy metal, secondly closely may gather materials on the spot, finally calculate its comprehensive cost.
The moderate-element composite fertilizer of this energy increasing yield and improving quality, its manufacture method comprises the steps:
Step one: batching, by SiO
2: 32% ~ 42%; CaO: 30% ~ 40%; MgO:20% ~ 30% and SO
3: 2.5% ~ 3.5% accurately takes raw mineral materials, and it is joined heat and determines according to kiln type: general by 750Kcal/kg grog ~ 950kcal/kg grog, shaft kiln capping, and rotary kiln removes the limit;
Step 2: prepared by raw material, by step one proportioned material grinding to crossing 4900 hole sizers, its screen over-size is no more than 5%;
Step 3: raw material homogenizing, by step 2 gained raw material pneumatic blending storehouse or many storehouses collocation, machinery fall storehouse make it homogenizing, SiO
2,the Aggregate Feeding Error of CaO, MgO is no more than 1%, SO
3aggregate Feeding Error be no more than 0.5%, join Thermal Error and be no more than 1%;
Step 4: clinker burning, above-mentioned material is calcined 1-8 hour in the stove of 1250 DEG C ~ 1350 DEG C, rotary kiln capping, boiler-turbine CCS removes the limit, and after gained clinker cooling, homogenizing is stand-by;
Step 5: make, is milled to 4900 hole square hole sieve screen over-sizes and is no more than 5% by step 4 gained chamotte powder, pack warehouse-in after the assay was approved through cooling, homogenizing.
In the present invention, the principle of material each composition by weight percent proportioning is as follows:
1, SiO
2content 32% ~ 42%, be preferably 34% ~ 40%; Work as SiO
2content more than 40% time, generate CaSiO
3, cause the solvability of fertilizer to reduce; Work as SiO
2content when being less than 34%, generate C
3s, lumps after causing fertilizer to apply field and solidifies, thus reduces activity and fertilizer efficiency significantly;
2, the content 30% ~ 40% of CaO, is preferably 32% ~ 38%, generates insoluble CaSiO when CaO content is less than 32%
3, cause the solvability of fertilizer to reduce; When CaO content more than 38% time one be possible generate C
3s, and cause luming, solidifying, reduce fertilizer efficiency; One is do not have the aluminum oxide in the f-CaO activating soil of complete reaction, thus the absorption Al causing crop too much
2o
3make agricultural-food seriously defective;
3, the content 20% ~ 30% of MgO, is preferably 22% ~ 28%, when the content of MgO is less than 22% because generating MgSiO
3and have a strong impact on the solvability of fertilizer; When MgO content more than 28% time, likely make batching time CaO, SiO
2ratio reduce, thus make sintering reaction insufficient, thus affect fertilizer efficiency;
4, SO
3content 2% ~ 4%, be preferably 2.5% ~ 3.5%, work as SO
3content when being less than 2.5%, its mineralization reduces, unfavorable good quality and high output low consumption; Work as SO
3content more than 3.5% time, easy to form bulk during sintering, seriously affects the operation factor of equipment, have impact on quality on the contrary and adds cost.
In a word, compared with prior art, the present invention not only starting material can suit measures to local conditions to gather materials on the spot, and to the silicon in supplementary soil, calcium, magnesium elements, phosphorus in activating soil and element silicon, the harmful heavy metals such as the cadmium in passivation soil, arsenic, chromium, mercury, lead have significant effect, and the farmland that particularly heavy metal is polluted possesses good repairing effect.
Embodiment
Below by embodiment, the present invention is further described
Embodiment one:
Will containing SiO
2caO MgO SO
3mineral press 34:36.5:27:2.5 percentage batching, join hot 800kcal/kg grog, cross 4900 hole square hole sieve screen over-sizes through raw mill grinding and be not more than 5%, when sintering 1 after homogenizing is qualified in the rotary kiln of 1300 DEG C, then cool grinding to 4900 hole square hole sieve surplus and be no more than 5% warehouse-in, homogenizing is up to the standards packaging warehouse-in.
