Abstract
The invention belongs to the field of energy conservation and emission reduction as well as waste resource utilization, and in particular relates to an organic-inorganic compound fertilizer special for corn and an energy conservation and emission reduction application method of the fertilizer. The application method is combined with a fertilizer production technology. According to the growth characteristics and nutrient demand of the corn, biomass power generation waste ash residue taking corn straw as a raw material, cultivation waste cow dung and an inorganic fertilizer are prepared into the organic-inorganic compound fertilizer special for the corn in a certain proportion. The preparation method of the organic-inorganic compound fertilizer is carried out according to the conventional organic-inorganic compound mixing production process and the obtained organic-inorganic compound fertilizer is used for planting the corns. The organic-inorganic compound fertilizer special for the corn has the characteristics that agricultural waste corn straw is a power generation raw material in the biomass power plant, and the waste ash residue produced by power generation of the corn straw, composted cow dung and the inorganic fertilizer are combined to prepare the fertilizer, thereby saving energy and reducing emission, saving fertilizer cost and providing an effective way for resource utilization of the wastes.
Description
Technical field
The present invention relates to energy-conserving and emission-cutting technology and utilization of waste as resource field, and combine the Production of manure technology, be specially the application method of a kind of special organic/inorganic compound fertilizer for corn and energy-saving and emission-reduction thereof.
Background technology
Along with the development of society, the waste that agricultural and industry produce can not be ignored, and utilization of waste as resource is one of mode of advocating energy-saving and emission-reduction.Corn is as one of main food crop and important feed source, and the quantum of output of its stalk is large, but also the field cost is high, and comprehensive benefit is low, and the straw utilization rate is not high, yet there is the possibility that increases greenhouse gas emission in the improper processing of stalk.Problem for the stalk resource utilization, in conjunction with the biomass power generation industry that develops rapidly at present, with the generating raw material of maize straw as biological energy power plant, waste lime-ash after the generating can be with the preparation chemical products, as sorbent material, as fertilizer sources use etc., owing to containing phosphorus, potassium and a small amount of trace element in the lime-ash, with low cost used as fertilizer, and can reduce greenhouse gas emissions, realize the purpose of energy-saving and emission-reduction.
In addition, along with the fast development of cattle-raising, its fecal pollution has become a great problem.At present, the processing mode of cow dung mainly contains Fertilizer Transformed, energy etc.Cow dung is good organic fertilizer after becoming thoroughly decomposed, and not only can promote the growth of plant, the quality of raising crop, can also improve the physico-chemical property of soil.
So, the growth needs that waste lime-ash, breeding waste cow dung and inorganic fertilizer behind the biomass power generation are combined according to corn is mixed with compound organic and inorganic fertilizer, not only can improve the physico-chemical property of soil, promote the growth of corn, save fertilizer amount, reduce the generation of greenhouse gases, thereby realize energy-saving and emission-reduction, but also provide the recycling direction for the maize straw lime-ash of biomass electric power plant and the pollution prevention of breeding waste cow dung.
At present, having had patent to disclose utilizes waste to produce the invention of fertilizer.China Patent No. is that the patent of invention of ZL200810010443.3 discloses a kind of vegetable waste organic fertilizer and preparation method thereof, and the used waste of this patent is vegetable castoff, and other used raw materials are also different from the present invention.China Patent No. is that the patent of invention of ZL200710052976.3 discloses a kind of technique of utilizing trade waste to produce carbon-rich organic phosphorus fertilizer, P in the phosphate fertilizer that produces
