Description
Technical field
The invention belongs to technical field of fertilizers, refer to a kind of composite fertilizer especially.
Background technology
In modern agriculture production, in order to improve the product of crop, chemical fertilizer is by the use of maximum.When starting most, the use of chemical fertilizer adopts single kind, the kinds such as such as urea, bicarbonate of ammonia, ammonium nitrate, diammonium phosphate, along with the progress of technology, research finds, the element of crop required in growth cycle is multifarious, and different species or the element required for different soils are also not quite similar, and the validity period of the chemical fertilizer of single variety is short, therefore in use, except using as base manure, also need the growth needs meeting farming by topdressing, the cost which results in agriculture production increases.
In order to adapt to the needs in different plant species or different soil, and reduce the cost of agriculture production, composite fertilizer's technology is developed, the fertilizer of present agriculture production be essentially composite fertilizer substitute, this is mainly because include multiple element in composite fertilizer, can be maximum may be provided in element required in vegetative period for different species.
But the validity period of present used composite fertilizer has had sizable raising compared with the validity period of the fertilizer of single-element, but still can not match with the growth cycle of crop.And after fertilizer decomposes at short notice, farm crop cannot all effectively utilize, unnecessary part can under the effect of various enzymes in soil, and form gas after being decomposed under the effect of rainwater or with rain water runoff, result in a large amount of wastes, and great pollution is caused to air and water source simultaneously.
In order to improve the utilising efficiency of fertilizer, prior art proposes the utilization ratio improving fertilizer by adding carbon nanomaterial in fertilizer, favourable to the production of farm crop.Such as application number is: the patent documentation of CN200710142932.X, proposes the technical scheme by adding the carbon nanomaterial of granularity within the scope of 5-200nm in the bicarbonate of ammonia in carbon containing chemical fertilizer, urea or its combination.

Embodiment
The invention provides a kind of composite fertilizer, described composite fertilizer includes the combination of at least two kinds of elements in nitrogen element, phosphoric or potassium element, and described composite fertilizer also includes carbon nanopowder; Described carbon nanopowder be nano-graphite colloidal sol or, obtained after super-dry by nano-graphite colloidal sol.
A kind of composite fertilizer, described composite fertilizer includes a kind of element in nitrogen element, phosphoric or potassium element, and described composite fertilizer also includes carbon nanopowder; Described carbon nanopowder be nano-graphite colloidal sol or, obtained after super-dry by nano-graphite colloidal sol.
In this application, composite fertilizer includes compound manure and mixed fertilizer.In this application, the proportion of each element in the composition of composite fertilizer shared by composite fertilizer can be determined about the standard of composite fertilizer according to existing country, on the other hand, the proportion of each element in the composition of composite fertilizer in composite fertilizer also can be determined not in accordance with national standard, this mainly because, by the technical scheme of the application, after interpolation carbon nanopowder, farm crop increase the utilising efficiency of each element in fertilizer, if still according to the ratio that national standard requires, can waste be caused.In this application, the consumption of nitrogen element, phosphoric or potassium element in composite fertilizer, can adjust the ratio of nitrogen element, phosphoric or potassium element according to different farm crop, different soils.
