Description

The manufacturing method of environment-friendly liquid fertilizer for drenching fertilizer in the green-house}

The present invention relates to a liquid nutrient solution for plant cultivation, and more specifically, using environmentally friendly SCB (Slurry Composting Biofiltration, eco-friendly low concentration) liquid fertilizer, and adds the environmentally friendly organic nutrients nitrogen, phosphoric acid, girly components derived from natural products, hormones, trace elements, etc. It relates to a method for producing a high quality liquid ratio by adding a functional ingredient of. As raw materials of environmentally friendly organic nutrients added to the SCB liquid, nitrogen nitrogen guano and natural sulfur sulfate are mixed and used in a fine size, and nitrogen, phosphoric acid, girly and other trace elements eluted from the nitrogen nitrogen guano and natural sulfur sulfate are used. By fertilizing liquid fertilizer by uniformly improving the crop nutrient source of liquid fertilizer, it promotes the growth of crops and improves the growth in low temperature environment.

In 2006, the amount of livestock manure was about 43,915 thousand tons, but most of them were discarded and recycled into liquid costs.

In the meantime, the government has implemented various support policies to promote the use of livestock manure. However, when the livestock manure is directly applied to farmland, the weight is heavy and bulky, so a separate spraying equipment is needed, and the composition as a fertilizer is not constant. As a result, it was difficult to spread evenly on farmland and there was considerable difficulty in spreading.

Recently, with increasing awareness of environmental pollution, sewage sludge disposal issues such as livestock manure have emerged as an important issue. Up to now, sewage sludge such as livestock manure has been collected and dumped on the high seas, but the dumping area designated in 1993 has been located in the joint fishing area of the neighboring countries, not on the high seas, due to the entry into force of the UN Maritime Act and the conclusion of fishery agreements with Japan and China. In March 2006, the Ministry of Environment, Agriculture, and Maritime Affairs and Fisheries agreed to ban sewage sludge offshore from 2012. Therefore, starting next year, Korea should also purify sewage sludge and food waste such as livestock manure.

In Korea, a lot of livestock manure is generated due to the development of livestock industry, and technologies for treating such livestock manure have been developed. In order to solve livestock manure and settle the resources of livestock manure, the government has implemented the Integrated Animal Waste Management plan, which applies livestock manure to resource recycling organic farming.

Biogas treatment using livestock manure to generate biogas can anaerobic fermentation of livestock manure to produce energy such as methane. In addition, odor reduction, slurry fertilizer value increase, global warming gas generation during storage period, and organic wastes are additionally treated.

In particular, the digestive fluid obtained by biogas treatment of livestock manure contains about 0.39%, 0.163%, and 0.479% of nitrogen, phosphoric acid, and garlic, respectively. There is high value as fertilizer.

Slurry Composting Biofiltration (SCB) liquid has less odor than general (high concentration) liquid, has homogeneity and cleanliness, can be applied as a grin in arable land, and contains corrosive substances and useful microorganisms other than nutrients as fertilizer. It has a high value as a fertilizer. In addition, when it is difficult to use the liquid ratio there is an advantage that it is easy to discharge the purification by simply treating at low cost.

Korean Patent Publication No. 2011-106692A 2011.9.29. summary Domestic Publication No. 2002-0050852A 2002.06.28. Lines 1-9 on page 6 Domestic Patent No. 10-0723338 B1 2007.06.30. 10-30 lines of 3

The liquid manure using SCB (Slurry Composting Biofiltration) has less odor than the general liquid manure, and it has homogeneity and cleanliness. Due to this lack and the composition ratio is not constant, it is difficult to determine the proper fertilization amount, labor costs are increased due to the increase of the spread amount, and environmental pollution may occur.

Therefore, in order to use as a fertilizer for crops, fertilizer components required for each crop, that is, a large amount and a trace element, must be properly mixed, and nutrients required for each growing season must be uniformly distributed. . Therefore, there is a problem of artificially enhancing the nutrients so that the SCB fluid using livestock manure can contain the nutrients required by the crop.

In order to solve the above problems, the SCB solution should be supplemented with the crop nutrients that are insufficient and appropriately supplemented with a large amount of elements such as N, P, K so as to contain the nutrients necessary for each crop or crop growth time. By using waste liquid generated from biogas treatment using livestock manure as a basic matrix, it adds eco-friendly organic nutrients (N, P, K) derived from natural products and mixes functional ingredients such as hormones and trace elements A liquid ratio can be manufactured.

The most important factor in producing a multi-functional liquid fertilizer using the waste liquid is to establish a liquid fertilizer manufacturing method and production process so that the macronutrients and micronutrients of the crop is properly mixed with the biogas waste liquid. As described above, the liquid fertilizer should be able to mass-produce the liquid fertilizer at a low cost, and the liquid fertilizer should be proved to be effective as a fertilizer for the desired crop, or the desired small size of the crop, through farmhouse demonstration tests.

In the present invention, in order to determine the proper fertilization amount by crop or small and to increase the crop nutritional component content of the SCB solution, nitrogen nitrogen guano and natural sulfuric acid having a high nutritional content in the organic product organic fertilizer are mixed with the SCB solution. As a result of analyzing the nutrients of nitrogen nitrogen guano, it contained 17 wt% of nitrogen, 13 wt% of phosphoric acid, and 3 wt% of girly, and was suitable as a source of nutrients for low concentration of SCB liquid. In order to make it possible to use the drop hose, the powder particle size of nitrogen nitrogen guano was finely divided into 250 ~ 325Mesh size.

In addition, the natural sulfuric acid mixed in SCB liquid contained 50% girly and 18% sulfur as a result of analyzing the nutrients, and serves to supply the girly and sulfur fertilizer components in the SCB solution.

Slurry Composting Biofiltration (SCB) liquid manure using livestock manure has less odor, compared to general liquid manure, has homogeneity and cleanliness, and can be applied by grinning in farmland and contains corrosive substances and useful microorganisms other than nutrients as fertilizer. It has a high value as a fertilizer. In addition, when it is difficult to use the liquid ratio there is an advantage that it is easy to discharge the purification by simply treating at low cost.

In the case of producing liquid fertilizer by mixing nitrogenous guano natural sulfate in the waste liquid generated from the biogas treatment of livestock manure, that is, SCB liquid, it is possible to supplement the nutrients of SCB liquid, and even in case of poor crop growth environment. By increasing the resistance there is an effect to improve the growth. When manufacturing environmentally friendly functional liquid fertilizer by mixing nitrogen nitrogen guano and natural sulfuric acid sulfate in the SCB liquid of the present invention, the liquid fertilizer can be mass-produced at low cost, and the crop showed a good effect as a fertilizer component at a desired time.

In the present invention, when the biogas is produced using livestock manure, the nutrients of the crops are mixed with the waste liquid to increase the nutrients of the crops, and produce eco-friendly functional liquid fertilizers equipped with the functionality of the crops such as low temperature resistance and pest resistance. In addition, it is effective to diversify the use of the waste fluid generated when manufacturing biogas using livestock manure.

The present invention relates to a method for producing environmentally friendly functional fertilizers that can be used for irrigation in facility cultivation using SCB (Slurry Composting Biofiltration) liquid which is a low concentration of livestock manure. In detail, the present invention relates to a method for producing environmentally friendly functional fertilizer for irrigation by mixing environmentally friendly nutrition and functional ingredients derived from natural products with SCB liquid in order to have a high nutritional content as fertilizer for irrigation.

The low-concentration SCB liquid is methane produced when fermenting livestock manure in an anaerobic state, which is a waste liquid having a low concentration remaining in the biogas treatment process, and the waste liquid lacks a nutrient component of a crop and has a non-uniform nutritional component. . Therefore, in order to supplement the crop nutrients of the wastewater generated during the biogas treatment of livestock manure and to manufacture the liquid fertilizer containing the nutrients necessary for each crop or the time of crop growth, N, P, K, etc. It is necessary to balance the nutrients to facilitate growth.

The low concentration SCB solution contains about 0.39%, 0.163%, and 0.479% of N, P, and K, respectively, and contains other trace elements such as iron, zinc, and manganese. Difficulties in judging the proper fertilization rate and excessive labor force due to the increase of the spread amount due to the lack of the nutritional content of the crop and the non-uniform ingredient ratio.

Therefore, in the present invention, in order to determine the proper fertilization amount by crop or small and to increase the crop nutrient content of the SCB solution, nitrogen nitrogen guano and natural sulfate having high nutrients in the organic product organic fertilizer were mixed with the SCB solution. As a result of analyzing the nutrients of nitrogen nitrogen guano, it contained 17 wt% of nitrogen, 13 wt% of phosphoric acid, and 3 wt% of girly, and was suitable as a source of nutrients for low concentration of SCB liquid. However, nitrogen nitrogen guano is in the form of a natural powder, and the particles are large and uneven, which causes clogging of the drop hose when used in a general irrigation facility. Therefore, in order to be able to use in the drip hose, the powder particle size of nitrogen nitrogen guano and natural sulfur sulfate was finely divided to 250 ~ 325Mesh size. The fine nitrogen nitrogen guano was mixed with the SCB solution and irrigated using a drop hose to the crop, and thus clogging did not occur.

In addition, natural sulfuric acid mixed in SCB liquid contained 50% of Gary and 18% of sulfur, which was suitable as a source of Gary and sulfur of SCB liquid.

The ratio of nitrogen nitrogen guano and natural sulfuric acid mixed in the SCB liquid was mixed in a ratio of 4 to 6: 3 to 5: 1 by weight ratio, preferably by mixing 5: 4: 1 to prepare a liquid ratio. The content of the liquid ratio is 5 to 10% by weight of nitrogen, 3 to 8% by weight of phosphoric acid, 4 to 8% by weight of girly, 1 to 4% by weight of sulfur (the rest of the water), and the composition is preferably nitrogen 7 A basic liquid ratio is prepared by making the weight percentage, 5% by weight phosphoric acid, 6% by weight girly, and 3% by weight sulfur. To give functionality to the liquid ratio of glycine betaine 6 to 8% by weight, seaweed extract Ascophyllum nordosum 4 to 6% by weight (the remaining water), preferably glycine beta 7.5% by weight, seaweed extract Asco Mix 5% by weight of filtrate islands. When the functional material is mixed and used in the liquid fertilizer, the crops grown in the high temperature during the summer and the low temperature during the winter have improved adaptability in the facility, so that the crops grow well.
