The content of the total nutrients of a special inorganic compound fertilizer for the wheat, which is provided by the invention, is 35.18%-45.03%, wherein the content of nitrogen is 16.58%-22.09%; the content of phosphorus pentoxide is 7.63%-11.13%; and the content of potassium oxide is 10.44%-12.82%. The mixing ratio of the nutrients is reasonable; the special inorganic compound fertilizer for the wheat is mainly applicable to the cultivation of the wheat in purple soil and yellow soil in the Sichuan basin, and has beneficial effects on the growth and the yield of the wheat to some extent; and synchronously, an effective approach is provided for the reasonable utilization of the combustion ash in the electric power generation by utilizing biomasses.
Description
Technical field
The present invention relates to a kind of wheat special inorganic compound fertilizer that utilizes the production of forest branch ash content and preparation method thereof, belong to the agricultural fertilizer technical field.
Background technology
Along with developing rapidly of biomass power generation industry, the quantity discharged of its forest branch burning back ash content increases year by year, as can not in time carrying out recycling, then pollutes the environment, and makes biomass fermentation power plant can't realize ordinary production.Contain phosphorus and potassium and the required trace element of some plant growths in the forest branch ash content, be prone to cause nutrient loss but use separately, using separately for a long time can the change soil physico-chemical property.Therefore be main raw material with forest branch ash content,, be equipped with the special-purpose fertilizer of a certain proportion of nitrogen phosphorus potassium inorganic fertilizer production crop and can realize reasonable utilization, reduce environmental pollution forest branch ash content according to nutrient demand and the growth mechanism of each crop.
Wheat is one of the staple food crop in Chuanzhong Qiuling district, and it contains the nutritive substance such as starch, fat, protein, VITAMINs, calcium, iron of needed by human body.So far, breeding improvement becomes the key that improves the wheat yield level, simultaneously, also can receive the remarkably influenced of soil, climatic factor and cultivation step.The Chuanzhong Qiuling district is Chinese most typical mesa hills area, with the hills blazon, the small stream ditch is in length and breadth for its remarkable geographic entity, mostly soil parent material is the red-purple sandstone and the mud stone of soft and hard alternation.Under its unique ecological environment condition, the suitable application quantity of nitrogen phosphorus potassium and the proportioning of improving yield of wheat cultivation it be not immediately clear.
The patent of invention of Chinese patent publication number CN101134691A and CN1403420A all discloses the compound method of a fertilizer special for wheat, and proportioning is N: P
2O
5: K
2O: Zn: Mn: Mo: B: Fe: rare earth nitrate: medical stone is 1:1.1-1.2: 0.5-0.6: 0.01-0.02: 0.02-0.03: 0.01-0.02: 0.01-0.02: 0.01-0.02: 0.01-0.02: 0.01-0.02; Though these two inventions all belong to fertilizer specially for wheat; But its concrete prescription comparatively complicated (needing ten kinds of starting material); And rare earth resources is rare, and cost is higher.The Chinese patent publication number is that the patent of invention of CN101492319A discloses a kind of fertilizer specially for wheat that on the corresponding fertilization method, can realize nitrogen, sulphur nutritive equilibrium; But should be applicable to the winter wheat that plant in area, the Plain of Huanghua Area by special use fertilizer; Particularly suitable strong gluten wheat; And need impose nitrogenous fertilizer twice, strengthen labour cost.Chinese patent publication number CN1793074A discloses the method for utilizing plant straw ash to produce multi-element fertilizer, but adds the quality that too many waste may reduce fertilizer, jeopardizes agricultural product security.Chinese patent publication number CN1907920A discloses a kind of method of utilizing stalk ash to produce nitrogen-phosphorus-potassium compound fertilizer, but the plant ash of this method neutral and alkali and monoammonium phosphate directly mix with urea, is prone to cause the loss of phosphorus fixation and urea.Chinese patent publication number CN101020612A discloses a kind of plant organic potassic fertilizer, but on the low side because of acidity in the preparation process, can increase the weight of soil acidification, and nitrogen, phosphorus nutrient content are low, uses in a large number and can strengthen labour cost.
Summary of the invention
It is raw material with forest branch ash content that the present invention provides a kind of, fertilizer specially for wheat that assembly is produced with a certain proportion of inorganic fertilizer and preparation method thereof.The present invention is equipped with a certain proportion of inorganic fertilizer according to the Sichuan wheat growth characteristics, has both satisfied the demand to nutritive element in wheat each vegetative period, can carry out reasonable use to forest branch ash content again simultaneously, reduces environmental pollution.
The technical scheme that the present invention solves the problems of the technologies described above is:
One fertilizer special for wheat is made up of forest branch ash content and inorganic fertilizer, and said forest branch ash content and inorganic fertilizer are by weight; Total nutrient is 35.18%-45.03%; Wherein nitrogen content is 16.58%-22.09%, and phosphorus pentoxide content is 7.63%-11.13%, and potassium oxide content is 10.44%-12.82%.。
The preparation method of this fertilizer specially for wheat comprises the steps:
A, acidity adjustment: forest branch ash content is put into reaction tank, add acidity regulator, regulate its pH between 6.5-7.5, wherein forest branch ash content nutrient content is P
2O
5Be 3%-6%, K
2O is 7.45%-12.8%.
B, mixing, granulation: the forest branch ash content after will handling is put into tablets press, adds the urea of preset proportion simultaneously, monoammonium phosphate, and Repone K and tamanori thorough mixing, wherein the specification of quality of urea is that N contains 46.3%, the specification of quality of monoammonium phosphate is to contain P
2O
5Be 44%, N is 11%, and the specification of quality of Repone K is to contain K
2O is 60%; Granulation when the fertilizer granularity reaches requirement, stops granulation.
C, oven dry: control dram temperature, letting the fertiliser granulates water cut be lower than 2% can cool off.
D, screening, packing: sieve into the fertiliser granulates that particle diameter is 2-4mm, the packing of weighing.
Beneficial effect of the present invention is:
The pollution to environment has been avoided in A, the handling problem that has solved forest branch ash content.
The loss of nutrient in the forest branch ash content has been avoided in the combination of B, forest branch ash content and mineral manure, possesses the quick-acting fertilizer efficiency of mineral manure simultaneously, can satisfy the nutritional needs of each growth phase of wheat.
C, special-purpose fertile disposable the applying of adopting are not done and topdressed, and be easy to use, reduced labour cost.
D, raw material of the present invention obtain easily, and cost is low, and the preparation process is simple, and be low to the machinery and equipment requirement of preparation, practices thrift cost, is beneficial to large-scale promotion application.
Embodiment
Below in conjunction with embodiment the present invention is made further detailed description.But should this be interpreted as that the scope of the above-mentioned theme of the present invention only limits to following embodiment.
