Description

  The present invention relates to a fungus bed medium with bamboo powder, and more particularly relates to a fungus bed medium with bamboo powder in which high safety in use, moisture content, and bamboo fiber chopped strands are repeatedly corroded and assimilated repeatedly.

In recent years, many farmers have been working on fungal bed cultivation. The cause of the increase is yearly crops that have been harvested after being cultivated, planted, planted and cultivated under natural conditions. Agricultural management has been considered extremely unstable due to wind damage such as typhoons and gusts, torrential rain, and other abnormalities.
And in order to cope with the expansion of consumption during the high economic growth period, agricultural management also actively incorporates fungus bed cultivation to ensure stable cultivation production without being affected by fluctuations in natural conditions to enhance agricultural production. Has been.
The adoption of fungus bed culture medium is also actively promoted in order to promote the cultivation of crops with the growth medium even in the vast open-air cultivation areas that have not been institutionalized. Has been made.

  By the way, in the era of high growth, a lot of synthetic soil conditioners and synthetic chemical fertilizers were used in the screaming of mass production and consumption, and the growth medium was changed. The original growth medium was changed to a growth medium contaminated with chemical compost, chemical fertilizers and pesticides.

  By the way, due to global warming on one side, management of forests and mountain fields on the other side, and lack of care and neglect, bamboo materials such as Japanese bamboo and bamboo shoots, which have strong growth potential, proliferate rapidly and unreasonably. In addition to the removal of nutrients from other trees due to expansion and expansion, the growth of trees and natural growth trees has been hindered by planting as well as natural growth due to the rapid growth and the sunshine blocking the leaves. It has become enormous. There has been a national demand for free cutting of bamboo that grows rapidly and involuntarily.

  For this reason, attempts have been made at various places to cut down the bamboo material that propagates rapidly and involuntarily and reuse it. However, the amount of harvested bamboo material to be harvested is enormous. It is desirable that the market for the system has a huge scale.

  In view of such circumstances, the inventors have formed bamboo fibers from the necessity of maintaining various processability in bamboo materials, and have conducted research on their performance. In a pressure extrusion device, increase the internal pressure to at least 15 kg / cm2 with a screw and strainer, press knead, cut into minced with a cutter, and discharge into the atmosphere from a nozzle with many discharge holes at the tip. Bamboo fiber chopped strands swelled, diffused and defibrated to maintain antibacterial properties and freshness in addition to physical properties such as dimensional stability and gas adsorbability in addition to tough and excellent flexibility As a result, it was found that the bamboo fiber chopped strands were excellent in entanglement while maintaining chemical properties such as properties.

  It is an object of the present invention to provide a fungus bed culture medium with bamboo powder in which a cultivated culture medium is entangled with bamboo fiber chopped strands of lactic acid bacteria fermentation.

  The technical means employed in the present invention in order to solve the above-mentioned problem is to break up bamboo materials such as 孟 mul bamboo, Japanese bamboo, bamboo shoots, etc. into required small pieces, and at least the internal pressure thereof is 15 kg / cm 2 or more by a pressure extrusion device. Pressure-kneading in a minced shape with a cutter and cutting the length to 20 to 200 mm, then discharging it into the atmosphere from a porous nozzle at the tip, swelling and diffusing, decomposing hard tissue and soft tissue, Using chopped strands of fibrillated bamboo fiber in which cell wall and cellulose and hemicellulose are dissociated from lignin, the entanglement covering thickness is 3m to 5m at the composting place of lower concrete and wood wall of about 40m3 volume In the range where the entanglement covering weight is in the range of 10,000 Kg to 15,000 Kg, the moisture content of the bamboo itself is 70%, giving about 10% moisture, and the moisture is Providing 酵熱 and 10% moisture further and at the same time become 70% such as vaporized. This measurement is repeated for about 2 to 3 months after measurement using a moisture meter. As for temperature control, the heat of fermentation is kept at 70 ° C., and when the ambient temperature is low such as in winter, the temperature is kept at 70 ° C. where the whole is covered with a vinyl sheet or the like. A thermometer is buried and managed daily. In addition, the bamboo fiber chopped strand entanglement envelope is cut back with a yumbo etc., and once per week so that the fermentation and moisture content become uniform. It is a fungus bed medium with bamboo powder characterized by repeated assimilation by corrosion decomposition.

The present invention comprises the above-described manufacturing method, and after crushing bamboo materials such as 孟 mul bamboo, Japanese bamboo, bamboo shoots, etc. into required small pieces, pressure kneading at least with an internal pressure of 15 kg / cm 2 or more by a pressure extrusion device. After cutting into a minced shape with a cutter and cutting the length to 20 to 200 mm, it is discharged into the atmosphere from a porous nozzle at the tip, and swells and diffuses to form a disorganized hard tissue and soft tissue, and to form a cell wall. Cellulose and hemicellulose are also dissociated from lignin fixation, and in addition to increased flexibility and bulkiness, the presence of starch granules around this cellulose and hemicellulose facilitates the involvement of microorganisms and corrodes the medium due to corrosion. Assimilation is possible.
Furthermore, since the bamboo fiber chopped strand is 3 mm or less 73%, 3 mm or more 17%, 5 mm or more 5%, 7 mm or more 5%, a long-term effect can be expected.

  In addition, regarding the germination and growth of the sown crops, the bamboo fiber chopped strands have antibacterial properties at the beginning, so that the fruit can be grown together with the growth. Strawberries, cucumbers, watermelons, cabotillas, etc. that grow are cultivated while avoiding malignant soil fungi and soil pests.

  After crushing 孟 mune bamboo to about 20 to 50 cm in advance, kneading it using a pressure extruder with an internal pressure of 50 kgg2, and cutting it with a cutter to a fiber length of about 2 to 20 cm, using a porous nozzle at the tip It is a bamboo fiber chopped strand which is discharged into the atmosphere and swelled and diffused. [Example 1]

In the following, the embodiment of the present invention will be described in detail with reference to the drawings. Regarding the germination and growth of agricultural products, the bamboo fiber chopped strands are not only antibacterial at the primitive time, but also can be easily grown from the entangled voids. Therefore, shiitake mushrooms are grown while avoiding malignant soil fungi and soil pests.
The speed of cultivation increases, and side buds and fractions increase.

The soil fertility is increased by the action of actinomycetes, lactic acid bacteria, phosphorus-lytic bacteria, etc., and the microorganisms grow by using sugar and minerals as feed. Because it contains a lot of amino acids and sugars, native lactic acid bacteria grow.
Moreover, since nitrate nitrate concentration is lowered by about 30 to 40% due to reduction of nitrate nitrogen in the crop body, the crop becomes delicious.

  Of course, the present invention has a material requirement, and since the present invention is used for a large medium area such as agriculture, and after harvesting, it is mixed with the medium and subjected to corrosion decomposition and assimilation with the medium. It is an absolute requirement that it is extremely inexpensive.

  Several methods have been proposed as means for the fungus bed medium with the bamboo powder of the present invention thus formed, and FIG. 1 shows a simple, efficient and stable formation method.

放線菌、乳酸菌、リン溶解菌等の作用で土壌の肥沃度が上がり、微生物が糖分やミネラルを餌として増殖する。アミノ酸や糖分を多く含んでいるので土着の乳酸菌が増殖するため、作物体内の硝酸態窒素の減少で硝酸イオン濃度が３０〜４０％程度低くなるので作物が美味しくなる。As means for the fungus bed medium with the bamboo powder of the present invention thus formed, several means have been proposed, but the ingredients of shiitake mushrooms cultivated by a method of forming with simple, efficient and stable quality are shown.

The soil fertility is increased by the action of actinomycetes, lactic acid bacteria, phosphorus-lytic bacteria, etc., and the microorganisms grow by using sugar and minerals as feed. Since it contains a lot of amino acids and sugars, native lactic acid bacteria grow, and the nitrate ion concentration is lowered by about 30 to 40% due to the decrease of nitrate nitrogen in the crop body, so the crop becomes delicious.

The fungus bed base material is “wood base material”, “nutrient source”, “water” and “bamboo powder” of the present invention. The most important points to be paid to during the cultivation process are “mixing and stirring”, “filling”, “sterilization”, “cooling”, “inoculation with bacteria”, “nurturing”, “fruit body generation” and “harvest”. It is.
The source of infection is various for humans, humidification water contamination, sterilization failure, inoculum contamination, insect infestation, etc., and the insects not only have a direct effect on the substrate, but also by the various bacteria brought in at the same time It also affects mycelium and fruit bodies. The constant temperature and high humidity environment is an optimal environment for harmful bacteria, and the “bamboo flour” of the present invention plays an important role in order to eliminate the influence as much as possible.
By introducing the bactericidal and antibacterial properties inherent to bamboo, which is a natural product, to the fungus bed base material, the bactericidal properties and antibacterial properties inherent to bamboo are fully demonstrated in each stage of the cultivation process. It works to keep it away.
