Background technology
Comprise in the production of food crop, each planting fruit-trees, vegetables in agricultural, need to use chemical fertilizer and chemical pesticide, can cause soil compaction, contaminate environment behind the chemical fertilizer life-time service.And soil property degeneration, the phenomenon that hardens also can take place in general fertilizer after using the certain period continuously, make negative effects such as effect of fertilizer decay.
In the patent No. is that ZL011004746, patent name are to propose a kind of method of getting potash fertilizer from potassium rich rock-lime hydro-thermal legal system, after potassium rich rock and Wingdale pulverizing, ball milling, mixing, in autoclave steam, carry out hydro-thermal reaction, get KOH, make potash fertilizer in order to produce sylvite.
The patent No. the inventor is that ZL021167745, patent name are in the multifunctional natural mineral preparation, a kind of multifunctional natural mineral preparation is provided, it is made up of yellow son, calcite, lazurite in medical stone, float stone, the stone, through selecting materials, pulverize, being mixed and made into.It can be applicable in the agriculture production, and as fertilizer sources uses, and can increase production and can keep the soil not harden, and is pollution-free; And manufacture craft is simple, and is cheap.Now this patent is widely used popularization at home, obtains very big benefit.
Summary of the invention
The purpose of this invention is to provide a kind of multielement natural mineral fertilizer, is that the patent No. that continues is the improvement invention of ZL021167745.It is a kind of fertilizer that has remarkable volume increase, improves soil, environmental-protection function; And its manufacture craft, using method are simple and convenient, and cost of material is lower, are easy to obtain, and its making, use cost are lower.
The objective of the invention is to realize by following technical scheme.A kind of multielement natural mineral fertilizer of the present invention, the feature of its first scheme are that it mainly is made up of following component: the medical stone 30-60 of ratio by weight, float stone 10-40, potassium felspar sand 10-25.
Alternative plan is in first scheme, and described potassium felspar sand 10-25 is replaced with calcite 5-15.Promptly comprise medical stone 30-60, float stone 10-40, calcite 5-15.
Third party's case is in first scheme, also comprises the quartzite 5-15 of ratio by weight.Promptly comprise medical stone 30-60, float stone 10-40, calcite 5-15, quartzite 5-15.
Cubic case is in first scheme, and described potassium felspar sand 10-25 replaces with quartzite 5-15.Promptly comprise medical stone 30-60, float stone 10-40, quartzite 5-15.
The 5th scheme is in first scheme, also comprises the calcite 5-15 of ratio by weight.Promptly comprise medical stone 30-60, float stone 10-40, potassium felspar sand 10-25, calcite 5-15.
The 6th scheme is in the 5th scheme, also comprises the quartzite 5-15 of ratio by weight.Promptly comprise medical stone 30-60, float stone 10-40, potassium felspar sand 10-25, calcite 5-15, quartzite 5-15.
The 7th scheme is in first scheme, also comprises the quartzite 5-15 of ratio by weight.Promptly comprise medical stone 30-60, float stone 10-40, potassium felspar sand 10-25, quartzite 5-15.
In above-mentioned each scheme, described float stone can replace with zeolite.
Its making method may further comprise the steps:
1) select materials, the ore of each component selected impurity elimination respectively,
2) pulverize, the ore separated pulverizing powdering with each component forms each component raw material,
3) batching is got each component raw material ready by formula rate,
4) mix, each component raw material of getting ready mixed,
5) granulation, with each component raw material granulation on tablets press that mixes,
6) packing, each the component raw material packing with after the granulation forms fertilizer of the present invention.
It is raw material that the present invention adopts medical stone, float stone, potassium felspar sand, quartzite, calcite in the natural crystal, and it is pulverized, and forms by different proportion ingredients, mixing manufacture, and technology is simple, and is with low cost, effective.Each above-mentioned natural crystal such as medical stone, float stone, calcite, quartzite once used for Chinese medicinal materials traditionally.The medical stone smell is sweet, warm, nontoxic.Float stone has another name called spray, pore is arranged as the moth nest, and body is empty and light, and smell is salty, flat, nontoxic.Calcite smell hardship, suffering, Great Cold, nontoxic.The quartzite smell is sweet, warm, nontoxic.Potassium felspar sand is the rock that contains potassium element.The available zeolite of above-mentioned float stone (pumice) (zeolite) substitutes, and float stone and zeolite are the porousness rock that the slag ejection produces.Each above-mentioned component raw material, domestic widely distributed, be easy to get.Help crop yield, soil improvement after the use.Because soil property degeneration, the phenomenon that hardens after using the certain period continuously, can take place in general chemical fertilizer, can make the effect of fertilizer decay.Contain various trace elements in the mineral fertilizer of the present invention the growths of farm crop is had promoter action, both can be used as fertilizer, increase the output of crop, and can improve soil, avoid degenerating, and help environmental improvement; Particularly be used with common fertilizer, its effect of fertilizer that significantly gains, and improve soil property.Its making, easy to use.The contriver once detected mineral fertilizer of the present invention, wherein contained 3.1 milligrams/kilogram of available phosphoruss, 153 milligrams/kilogram of available potassium, pH value 8.4, exchangeable calcium 4.88 * 10
3375 milligrams/kilogram in exchangeability magnesium, effectively boron is 234 milligrams/kilogram, effectively sulphur is 302 milligrams/kilogram, effectively iron is 16.1 milligrams/kilogram, 514 milligrams/kilogram in full manganese, effectively copper is 0.31 milligram/kilogram, effectively zinc is 0.41 milligram/kilogram, complete plumbous 44.8 milligrams/kilogram, 0.288 milligram/kilogram of full cadmium, 7.41 milligrams/kilogram of full chromium, 2.770 milligrams/kilogram of arsenic, wherein elements such as available phosphorus, available potassium, pH value, exchangeable calcium, exchangeability magnesium, effective boron, effective sulphur, effective iron, full manganese, effective copper, effective zinc all have good effect to soil and farm crop.Through using proof, these elements can make soil not harden, and become loose, and activation is significantly increased production crop.
In sum, the present invention is the mineral fertilizer of being made up of natural crystal, is a kind ofly to have multiple element and can increase production and improve the soil the fertilizer of environmental protection and public nuisance free; Its making, use simply, cost is low.Be applied in the agriculture production, be used as mineral manure or with common fertilizer, significantly volume increase improves quality of agricultural product and nutritive ingredient, improves the soil, and is pollution-free.
