Description

Fertilizer manufacturing method using Yeongdeok Crab and fertilizer manufactured by the method {Method for producing a fertilizer by using crabs and fertilizer manufactured}

The present invention relates to a fertilizer manufacturing method using the youngdeok crab, and to a fertilizer prepared by the method, more specifically, after mixing the crab and food waste, rice husk, etc. of the main material Youngdeok crab, and fermented for a certain period of time chitosan The present invention relates to a fertilizer production method using Youngdeok crab and a fertilizer produced by the method that allows a large amount of components.

In general, compost has been used for a long time, such as pig manure, poultry meal, cow manure compost. These animal manure compost contains nitrogen, phosphoric acid, and caliber, but each type of animal compost is often concentrated on one component, and it does not show enough fertilizer effects such as chemical fertilizers. In addition, when using livestock manure, less fermented livestock manure has many organic matters that can be easily decomposed, so there is a risk that it may be rapidly decomposed in the cultivated soil and cause gas disturbances. May cause soil pests.

In order to supplement the problems of general compost, chemical fertilizer containing nitrogen, phosphoric acid and kali, which are necessary for fertilizer, is used together with general compost. However, it is well known that as fertilizer use increases, fertility of the land decreases gradually, the amount of fertilizer absorbed by crops decreases, and soil and water are contaminated.

Chitosan is mainly contained in crustaceans such as shrimp, crab shell or squid bone, and has high organic content, so it is generally used as livestock feed or bird feed, and the chitosan is used for growing other crops such as leek. As a result, it was confirmed that crop growth was promoted and quality was improved, and its efficacy was proved. In addition, crab shells contain 4.3%, 5.3% and 0.25% of nitrogen, phosphoric acid and kali which are essential ingredients of fertilizer, respectively. Accordingly, the utilization of the crab shell, which was a waste resource, is gradually increasing.

Accordingly, an object of the present invention is to solve the above problems, by using chitosan to improve the productivity of the crop and crab containing nitrogen, phosphoric acid and kali which are essential elements of fertilizer as raw materials of fertilizer As an alternative fertilizer, it is to reduce the pollution of the soil and to provide an environmentally friendly fertilizer, and to provide fertilizers by the method.

In order to achieve the above object, the present invention comprises the first step of preparing a crab meal, slaughtered meal, slaughtered meal, food waste, shells, zeolites and chaff which is a raw material of fertilizer, and then crushed the chaff; A second step of mixing the crabmeat, slaughtered meal, slaughtered meal, livestock meal, food waste, shells and zeolites to form a first mixture; A third step of spraying the cultured microorganisms on the first mixture and mixing the crushed rice hull in a ratio of 1: 1 to form a second mixture; A fourth step of carrying out anaerobic fermentation while preheating the second mixture mixed by the third step to a temperature of 45 to 50 ° C. in a stockyard; A fifth step of introducing an anaerobic fermented second mixture by the fourth step into a fermenter, spraying the cultured microorganisms, and then injecting air to preheat the aerobic fermentation to a temperature of 75 to 85 ° C .; A sixth step of attracting the second mixture fermented by aerobic fermentation by the fifth step to a stockyard; It provides a fertilizer manufacturing method comprising a seventh step of filtering and finally sorting the fertilizer finally fermented by the sixth step.

The present invention also provides a fertilizer produced by the above method.

Hereinafter, an embodiment of the present invention will be described in detail.

The first step is a step of preparing a raw material of fertilizer. In this first step, first, rice husk, crabmeat, slaughter meal, food waste, livestock meal, slaughter meal, shell, and zeolite are prepared. The chaff is crushed to a size of 1.5 mm using a chaff crusher. In this case, it is preferable that the crabmeat use Youngdeok crab, which contains a large amount of lime powder, which is suitable as a raw material for fertilizer, and the zeolite has an effect of preventing acid soil, which is used as a farmland soil improver. Powder has been mainly used as an organic self-fertilizer, and the chaff is a by-product of agricultural products and has a high content of various trace elements and organic matter compared to sawdust, and is suitable as a raw material of fertilizer.

Next, except for the chaff, the second step is to prepare a first mixture by mixing 15% crabmeat, 15% slaughtered meal, 15% food waste, 20% livestock meal, 15% slaughtered meal, 10% shell and 10% zeolite. to be. At this time, the first mixture contains about 90% water.

Next, the third step is a step of mixing the first mixture and the crushed chaff to make a second mixture. In this third step, the microorganisms cultured in the first mixture are first sprayed at about 1000 cc per ton of the first mixture. Then, the crushed chaff and the first mixture sprayed with the culture microorganisms are mixed and stirred in a ratio of 1: 1 to form a second mixture. At this time, the second mixture contains about 70% water.

Next, the fourth step is a step of depositing the second mixture in the storage tank. At this time, the second mixture is preheated to a temperature of 50 ℃ while soaked for about 7 days to anaerobic fermentation.

Next, the fifth step is a step of injecting the anaerobic fermented second mixture in the fourth step into a baroque fermenter to aerobic fermentation. In this fifth step, first, the microorganisms cultured in the second mixture are sprayed and air is injected, followed by fermentation while preheating at a temperature of 80 ° C. for about 15 days. At this time, during the winter period from November to February, the fermentation period is doubled to about 30 days.

Next, the sixth step is a process for final fermentation by holding the second mixture fermented through the fourth step in the stockyard for about 3 months.

Next, the seventh step is finally filtered through the fertilizer completed through each of the above steps, and the raw material that is not properly crushed is selected and removed, and then packed by 18 kg.

According to the present invention as described above, by using a fertilizer containing chitosan components, there is no need to add pesticides or chemical fertilizers to the crop separately, so that the cost and effort associated with crop cultivation can be reduced, thereby reducing the production cost. In addition, since harmful ingredients in pesticides or chemical fertilizers are not absorbed by the crops, it is possible to harvest large quantities of good quality crops.

In addition, according to the present invention, the soil using the fertilizer containing chitosan component to increase the beneficial actinomycetes, while inhibiting harmful filamentous bacteria to produce excellent agricultural products, reduce the use of chemical fertilizers, which are the main cause of soil pollution Can reduce contamination.

In addition, according to the present invention, the effects on the crops last longer than the application of chitosan liquid directly to the crops, and makes the crops strong throughout the entire growth stage of the crops, which makes them resistant to rain and wind doping, resulting in higher maturity rates. Higher yields, especially resistance to pests, resulting in higher yields. Specifically, in the case of fruit vegetables such as red pepper, resistance to anthrax is increased, so that high-quality crops can be harvested without using pesticides separately, and the storage of harvested crops is improved, so that the crops can be stored for a long time. It can reduce the damage caused by injury. In the case of fruit trees, the sugar content is increased and the taste is excellent, so the marketability is improved and the storage properties of the fruits are also improved.
