DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an organic fertilizer obtained by blending rice bran pellets with effective microorganisms, and more particularly, to a rice bran pellet characterized by simultaneously combining aerobic bacteria and anaerobic bacteria. The present invention relates to an organic fertilizer containing a microorganism.

[0002]

2. Description of the Related Art Hitherto, only organic fertilizers obtained by adding oily scum or fish scum to defatted rice bran or the like were present.
Because rice bran itself is a powder, it cannot be sprayed mechanically by agricultural machinery, and if it is kept for a long period of time, it will oxidize and clump, making it difficult to spray it by hand if stored for a long period of time. Difficult to spray on average,
Moreover, the rice bran itself did not corrode due to the absence of bacteria.

[0003]

SUMMARY OF THE INVENTION Rice bran has been evaluated as an organic fertilizer rich in nitrogen and phosphoric acid,
Due to the difficulty of handling it, it was difficult to use it in modern agriculture. In order to solve such inconveniences in using rice bran, the present invention compresses rice bran to form pellets, realizes an easy-to-handle rice bran-based organic fertilizer, and further purifies bacteria, suppresses pathogens, It aims to provide a new organic fertilizer by combining effective microorganisms that are effective in promoting growth. Furthermore, in order to preserve the growth environment of anaerobic microorganisms combined with rice bran, the pellets are in an antioxidant state.

[0004] Therefore, the present invention provides a rice bran pellet comprising a composite of an effective microorganism which is composed of aerobic bacteria and anaerobic bacteria and which decomposes organic matter in soil, and which is formed into a pellet. Organic fertilizer containing effective microorganisms.

[0005]

The organic fertilizer comprising the above-mentioned rice bran pellets according to the present invention and an effective microorganism is blended with the rice bran rich in organic components, so that the nutrient environment necessary for survival of the effective microorganism is reduced. Secured. In addition, since this effective microorganism is a composite of aerobic bacteria and anaerobic bacteria simultaneously, soil erosion (soil purification), which functions only when aerobic bacteria and anaerobic bacteria coexist in the past, does not function. An easy-to-perform environmental system was secured.

[0006] That is, aerobic bacteria live near the soil surface, act on oxygen as nutrients to produce organic components,
The anaerobic bacteria act as nutrients for the aerobic bacteria to produce organic components, and as long as the balance is maintained, the organic components work to purify the soil.

When the coexistence relationship between aerobic bacteria and anaerobic bacteria is disrupted due to the occurrence of mosquitoes (a kind of anaerobic bacteria causing pine wilt, etc.), a fungicide or the like is added to the soil. The seeds are sown to kill the worms, but the fungicide kills aerobic bacteria in the soil first. This means
Many aerobic bacteria that require oxygen live near the surface of the soil, but these aerobic bacteria are first attacked because they first encounter a fungicide attack, and anaerobic bacteria that live near the bottom of the soil Is difficult to eradicate, and as a result, only anaerobic bacteria grow in the soil more, and the existence balance of both bacteria is disrupted.

Therefore, the soil may be carefully cultivated and air may be blown into the soil to activate the aerobic bacteria, but the once broken balance is hard to return. As the distribution of anaerobic bacteria grows,
The roots of crops and plants will be attacked by pathogenic bacteria, and good crop growth will not be expected.

[0009] The organic fertilizer of the present invention fertilizes the soil with an organic fertilizer mainly composed of aerobic bacteria and anaerobic bacteria that are deficient in the soil, so that the presence of both bacteria in the soil is balanced. To help maintain By the action of the above effective microorganisms, the corrosion of soil is promoted, the growth of agricultural crops and plants is promoted, and the bacterium in the vicinity of the root is purified and the pathogen is suppressed.

Further, the present invention provides a method of combining rice bran (usually containing about 14% of water) with two kinds of bacteria,
Since it is formed in the pellet body, aerobic bacteria easily survive near the surface of the pellet body, and anaerobic bacteria easily survive because the inside of the pellet body has no air permeability. Therefore, an organic fertilizer in an antioxidant state can be obtained as a whole.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments. Example 1 450 kg of rice bran was mixed with 18 liters of a 300-fold diluted fermentation-synthetic soil biosolution as an effective microorganism, and a pellet making machine was used to produce a columnar pellet having a diameter of 4 mm and a length of about 1 cm. Then, organic fertilizer was obtained. Here, the fermentation-synthesis-type soil biofluid is a liquid that holds a microorganism having aerobic bacteria and anaerobic bacteria in a fermentable state, and details thereof are as follows.

Here, the fermentation-synthetic soil biofluid is obtained by extracting 80 or more kinds of effective microorganisms existing in nature from bacteria in nature and fermenting the extracted high-quality organic matter at low temperature. The main purpose of use is to purify and revitalize the soil by the combined use of effective microorganisms, to suppress the occurrence of continuous cropping problems and pests, and to promote the growth of crops. The microorganisms to be added to the fertilizer used in this example are those prepared by combining microorganisms useful for soil improvement that are separated by a conventional method from good-quality soil or decayed organic fertilizer, fermented food, etc. . Among the above fermentation-synthesis type soil biofluids, the main aerobic bacteria include Bacillus natto, Bacillus, Azotobacter, actinomycetes, acetic acid bacteria, and the like.The anaerobic bacteria include yeast as the main one. , Lactic acid bacteria, photosynthetic bacteria and the like. In the specification of the present application, the term "anaerobic bacteria" is used to include microorganisms such as yeast in addition to bacteria.

The effective microorganisms are mainly aerobic bacteria and effective microorganisms to which anaerobic bacteria are appropriately added, for example, actinomycetes (antibacterial substance-producing bacteria), fermenting microorganisms (lactic acid bacteria, yeasts), and nitrogen fixation. There are bacteria (Azotobacter, Amyrobacter), photosynthetic bacteria, and alga (photosynthetic microorganisms).

First, actinomycetes are used to promote the purification, sterilization, and growth of organisms such as bacteria, viruses, and pathogenic bacteria.

The fermenting microorganism is for producing amino acids, sugars, vitamins and other physiologically active substances, and for purifying and sterilizing various germs.

The nitrogen-fixing bacterium fixes nitrogen from the air to produce a nitrogen fertilizer, and utilizes a nodule fungus that inhabits the root of a crop.

The photosynthetic bacterium and the alga are for synthesizing decomposing bacteria, decomposed products, organic substances, and inorganic substances by light or heat energy, and transferring any substance to positive charge.

Therefore, unlike the conventional chemical fertilizers and organic fertilizers, the organic fertilizer of the present invention is not used for fertilization, but promotes the propagation and establishment of effective soil microorganisms. It is a mixture. The most suitable environmental conditions for the survival of microorganisms are wet soil with a pH of about 6.0 to 6.5.

In nature, there are basically two types of microorganisms: microorganisms that lead animals and plants and other objects to resuscitation.
Microorganisms that lead to degradation are mixed. The fermentation-synthesis-type soil biofluid of the present application is a group of microorganisms belonging to the former, and it is known that there are typically yeasts, lactic acid bacteria, photosynthetic bacteria, useful actinomycetes, and the like.

The microorganisms are classified into aerobic microorganisms and anaerobic microorganisms, and the microorganisms obtained by coexisting these microorganisms simultaneously instead of using these microorganisms alone are the fermentation-synthesis-type soil biofluids of the present invention. It is.

The fermentation synthesis type soil biofluid of the present invention will be described with reference to FIG. A 3000-liter combined culture tank 1 (combined with aerobic and anaerobic microorganisms) is installed in a culture room constantly set at 20 to 21 ° C., and a liquid obtained by culturing the representative microorganism described above is placed therein. To store. For example,
Microorganisms are mixed in groundwater, and a crude sugar solution, a pregelatinized starch solution, a stabilizer, a seawater containing a mineral component, a chitin chito acid necessary for culturing both microorganisms, and the like are contained as a feed for the microorganisms.

In the figure, reference numeral 2 denotes an anaerobic culture tank, which is a culture tank for stabilizing only anaerobic microorganisms among the mixed microorganisms.

In the figure, reference numeral 3 denotes a liquid stored in the combined culture tank 1 and the anaerobic culture tank 2 which is pumped up and introduced therein. This is a mixed culture tank for stabilizing the mixed state of the products. The mixed culture tank 3 sprays pressure onto a predetermined portion of the conventional fertilizer production process, and mixes rice bran with another fixing agent (for 500 liters). ).

The pelletized fertilizer thus produced is sealed in a bag, and further fermented in a bag using the nutrients of rice bran as food, and has an antioxidant activity in which aerobic microorganisms and anaerobic microorganisms coexist. It becomes an excellent organic fertilizer.

Comparative Example 1 A columnar pellet having a diameter of 4 mm and a length of about 1 cm was directly produced by a pelletizer without adding any effective microorganisms to 450 kg of rice bran to obtain an organic fertilizer.

Comparative Example 2 450 kg of rice bran was used as an organic fertilizer without being pelletized.

The soil of the above Example 1, Comparative Example 1 and Comparative Example 2 was cultivated by sowing 40 kg per 100 square meters. At that time, conventional fertilizer was applied at the same time. Spinach, eggplant, peppers and radish were grown on the soil.

In addition, root activity became inactive, soot disease occurred on the surface of the tree, and the vitality of the tree was reduced by virtue of the parasitic giant mosquito bug.
An experiment was also conducted in which the organic fertilizer of Example 1 and the organic fertilizers of Comparative Examples 1 and 2 were applied.

Result 1 (spinach) In the case of Example 1, seeds emerged 3 to 4 days after sowing and 10
The stalks have risen in the day. Harvest was carried out in about 30 to 40 days, and the spinach was sweet, stalked, large and fresh with good quality. Comparative Example 1
The seeds of 2 and 3 were sowed in 3 to 4 days, sprouted in about 10 days, the stem became slightly thicker, but fell down without standing, and harvested in about 30 to 40 days. The spinach was less sweet than Example 1, and the stem was weak.

Result 2 (Eggplant, Bell Pepper) In Example 1, the seedlings were planted and the stems grew in about 20 to 30 days, and the crops became tight. The yield increased, and even if left indoors for a week, high-quality eggplants and peppers that did not wither and were firm were obtained. In Comparative Examples 1 and 2,
Compared to the one in Example 1, the length was longer (it became a soft crop with only the back extended), the stem was relatively elongated, and the yield was half of that in Example 1, and it was left indoors for 3 days. Eggplant, peppers that withered alone.

Result 3 (daikon) The seeds of Example 1 and Comparative Examples 1 and 2 were sowed 3 to
Leaves emerged in 4 days and harvested in about 40-50 days.
Although there is not much difference in the yield between Example 1 and Comparative Examples 1 and 2, the one in Example 1 was a sweet and tasty radish, whereas the one in Comparative Examples 1 and 2 was an example. The radish was clearly inferior in quality to the one.

Result 4 (Sazakana Tree) The root activity became inactive, soot disease occurred on the tree surface,
A tree of Sazaka (Tsubakiaceae) with a height of about 2.5 meters, whose vitality has declined due to the disease of giant insects parasitic on it,
About 1 kg of each tree was fertilized, and the state of the tree was observed 40 to 50 days later. In the case of Example 1, the vigor of the tree became active, parasitic parasites died, and a large number of new shoots (a state in which the trunk buds also appeared) appeared. On the other hand, in Comparative Examples 1 and 2, there was no significant change from the state before fertilization.

As can be seen from the above results, the organic fertilizer of the present invention produces an organic phosphoric acid which has a particularly large effect on the growth of the crop. It contributes to an increase in the roots of the company. Rice bran itself usually contains about 2% of organic phosphoric acid, but 4.89% in the pellet of the present invention due to the coexistence of aerobic and anaerobic bacteria.
It has been found that a certain amount of organic phosphoric acid is contained.
The only difference between Comparative Examples 1 and 2 was the difference in the ease of sowing the organic fertilizer during mechanical spraying.

Conventionally, in acidic soil, organic phosphoric acid content also
Although it is difficult to change to ammonia phosphate, the organic phosphoric acid content in the organic fertilizer of the present invention is easily changed to ammonia phosphate in soil by the activity of effective microorganisms.

The organic fertilizer of the present invention also has an effect of removing an odor caused by the generation of ammonia gas due to the activity of lactic acid in refrigerators, toilets, barns, and garbage dumps. For example, there is an example of an experiment in which when a small amount of the organic fertilizer of the present invention is put in a refrigerator, the odor can be removed two days later.

[0036]

Thus, according to the present invention, it has an excellent function as an organic fertilizer for agricultural crops, and since it is a pellet having a low moisture content during storage, it is difficult for fermentation of effective microorganisms to be compounded. Spraying on machines and fields,
In addition, it is easier to manage, and after fertilization, fermentation of effective microorganisms proceeds only by adding water, and the effect of oil and nutrients and combined bacteria of rice bran promotes soil corrosion and favorable soil improvement. There is.
