Abstract

The invention provides a technology for producing saline-alkali soil improving fertilizer by utilization livestock and poultry manure of culturing farms. The technology is composed of four steps: addition and mixing of raw materials, addition of composite fungal agents, aerobic and anaerobic combined fermentation and the production of saline-alkali soil improving fertilizer. The method is characterized in that livestock and poultry manure (pig manure and cow manure) generated from culturing farms and conditioning agents are mixed in a certain ratio; then optimized composite fungal agents selected through tests are added in the mixed materials; organic fertilizer raw materials are prepared through aerobic and anaerobic combined fermentation; finally the organic fertilizer raw materials and desulfurized gypsum are mixed in a weight ratio of 9:1. The added conditioning agents are edible fungi residues. The pig manure, the cow manure and the edible fungi residues are mixed and stirred in a volume ratio of 5:3:2. The devices used for the aerobic fermentation comprise a stirring overturning machine (patent number: ZL 00234458.0). The anaerobic fermentation employs a natural stocking and storing way. The desulfurized gypsum is waste generated from flue desulphurization of thermal power plants. Harmless and resource utilization of livestock and poultry manure of culturing farms is ensured, secondary pollution is prevented, and organic matters which are easy to corrupt and stink are stabilized, which turns harm into good.

Description

A kind of method of utilizing plant's feces of livestock and poultry to make reclamation of salinep-alkali soil fertilizer

Technical field

The present invention relates to the technology that the rural area organic solid castoff is processed, particularly a kind of technology of utilizing plant's feces of livestock and poultry to make reclamation of salinep-alkali soil fertilizer.

Background technology

Environmental improvement in the new rural area of Building Tianjin is major issue urgently to be resolved hurrily at present, and the organic waste in rural area (emphasis is livestock and poultry feces) are again important source of pollution of rural environmental pollution.According to investigations, organic waste can account for the 60-70% in rural environmental pollution source.If utilize the science treatment process that the rural area recycling organic waste is innoxious and be processed into reclamation of salinep-alkali soil fertilizer, this has just found reliable effective way for the organic waste pollution problem solved in new countryside construction.This approach had both alleviated rural environmental pollution, for countryside and peasantry brings economic benefit and environmental ecological benefit, can provide quality matetrial for developing China's coastal saline-alkali soil greening and plantation cause again, this will become an Important Action that improves Countryside Environment Rectification and promotion agricultural sustainable development.

The rural area organic waste output of China is very high, the severe contamination rural environment.Statistics in 2010, only the rural area feces of livestock and poultry just reaches more than 2,000,000,000 tons, by its Nitrogen-and Phosphorus-containing potassium conversion, is equivalent to 0.22 hundred million ton of urea, 0.11 hundred million ton of calcium superphosphate and 0.17 hundred million ton of vitriolate of tartar.Only feces of livestock and poultry contained nutrient in rural area just can reach 40.7% of the total input amount of city's farmland nutrient (being mainly chemical fertilizer).The commercialization processing that develops into the rural area feces of livestock and poultry of nearly ，Wo city large-scale cultivation industry during the last ten years provides favourable condition.

Summary of the invention

The invention provides a kind of technology of utilizing the plant feces of livestock and poultry to make reclamation of salinep-alkali soil fertilizer, by adding raw material, be mixed, add composite fungus agent, aerobic-anaerobic combined ferment, make fertile four steps of the reclamation of salinep-alkali soil and form.It is characterized in that feces of livestock and poultry (pig manure and cow dung) that plant is produced and amendment are according to must the ratio mixing, add through overtesting and optimize next composite fungus agent in mixture again, make the organic fertilizer raw material through the aerobic-anaerobic combined ferment, finally fertilizer raw material and desulfurated plaster are mixed according to the weight ratio of 9: 1.The amendment added is edible fungi residues.Pig manure, cow dung and edible fungi residues volume according to the ratio of 5: 3: 2, puddled.The equipment that aerobic fermentation is used has: stir overturning machine (certificate of patent number: ZL 00234458.0), anaerobically fermenting adopts the mode of nature stocking and storing.The present invention is pig manure and the cow dung (water ratio 80% left and right) that plant is produced, edible fungi residues discarded after interpolation production edible mushrooms is as the fermentation amendment, pig manure, cow dung and edible fungi residues mix according to the volume ratio ratio of 5: 3: 2, make mixture, the moisture control of mixture is at 50%-60%; Add the aerobic fermentation composite fungus agent in the material mixed, adding proportion accounts for mixture mass percent 0.4%; By the aerobic fermentation overturning machine, mixture is carried out to aerobic fermentation in the aerobic fermentation groove, fermentation time is 7-12 days; After aerobic fermentation finishes, material is transported to fermenter, adopt the mode of nature stocking and storing to enter anaerobically fermenting, the number of days of anaerobically fermenting is about 20 days, and whole fermenting process finishes; By fertilizer raw material pulverizing, sub-sieve, make the fertilizer raw material subsequently; Finally fertilizer raw material and desulfurated plaster are mixed and made into to reclamation of salinep-alkali soil fertilizer according to the weight ratio of 9: 1.We are by mixing according to a certain percentage, add the aerobic fermentation microbial inoculum by feces of livestock and poultry and edible fungi residues, by aerobic, anaerobism combined ferment, make the complexity in feces of livestock and poultry organic matter degradation, kill pathogenic bacteria and parasitic ovum etc., realize the stabilization of feces of livestock and poultry and innoxious, then make reclamation of salinep-alkali soil fertilizer by desulfurated plaster.Say more specifically to rest and grow an organic waste such as feces of livestock and poultry of discharging, by aerobic, anaerobism combined ferment, reach purpose innoxious, resource utilization, make reclamation of salinep-alkali soil fertilizer; Reclamation of salinep-alkali soil fertilizer can be improved soil in the process of saline-alkali soil afforestation and saline-alkali soil agricultural planting, increases the gas permeability of soil, and a technology of nutrient is provided for plant-growth again simultaneously.Guarantee that plant's solid waste rationally utilizes, prevent secondary pollution, make the easily smelly organism stabilization of corruption, turn harm into good.

Embodiment

The volume of pig manure, cow dung and the edible fungi residues that plant is discharged is puddled according to the ratio of 5: 3: 2, makes mixture, and the mixture moisture control is at 50%-60%; Add the aerobic fermentation decomposing agent in mixture, adding proportion accounts for the mass percent 0.4% of mixture; By tilting device, mixture is carried out to aerobic fermentation in the aerobic fermentation groove, fermentation time is 7-12 days; Subsequently material is transported to fermenter, adopt the mode of nature stocking and storing to carry out anaerobically fermenting, fermentation time is about 20 days, and whole fermenting process finishes; By fertilizer raw material pulverizing, sub-sieve, make the fertilizer raw material subsequently; Finally fertilizer raw material and desulfurated plaster are mixed and made into to reclamation of salinep-alkali soil fertilizer according to the weight ratio of 9: 1.The equipment that whole process is used has: stir overturning machine (certificate of patent number: ZL 00234458.0).
