Description

  The present invention relates to a method for producing a soil improver based on bamboo charcoal and bamboo vinegar.

  Bamboo grows naturally all over the country, but there are still no useful ways to use it. However, bamboo is much easier to cut and grow faster than trees. In recent years, bamboo charcoal has come to be looked at for the purpose of preventing the devastation of bamboo forests (abandoned bamboo forests), effectively utilizing them as resources, establishing them as local environmental industries, and revitalizing local industries. When bamboo charcoal is burned, it can be burned in about 1 week for conventional clay pots and about 2 days for natural dry distillation coal production equipment, so cheap bamboo charcoal can be obtained.

  However, the present situation has not yet reached the effective use of bamboo charcoal. In particular, when used in a field as a soil conditioner, there is a problem that it floats up when it is sprayed, plows the soil, or when the paddy field is filled with water. On the other hand, various attempts have been made to enhance the soil improvement effect of bamboo charcoal, but such a good method has not yet been established.

Patent Document 1 below discloses a method of mixing bamboo vinegar with bamboo charcoal and a method of adding bamboo to charcoal after adding seawater.
JP 2006-124711 A

  However, in this case (Patent Document 1), the bamboo material cut into a certain length was put in a carbonization furnace and baked, so it took time and effort to pulverize the finished bamboo charcoal. Moreover, it was necessary to provide a large-scale facility for preventing dust scattering generated during pulverization.

  Furthermore, in order to increase the effect as a soil conditioner, a method of including seawater has been proposed, but it took time to penetrate into the interior because bamboo was immersed in seawater before being crushed. Conceivable.

  In order to solve the above-mentioned problems, the bamboo charcoal soil improvement accelerator according to the present invention includes a step of cutting grown bamboo and drying it for about half a year to a moisture content of about 15 to 20% suitable for carbonization, and crushing the dried bamboo After pulverizing to 10 mm or less with a machine, immersing the crushed bamboo material in seawater diluted with water to a salt concentration of about 0.35% for 1 to 4 days, and then draining and drying for about 5 days It is characterized by comprising the steps of carbonizing in a carbonization furnace and mixing the bamboo vinegar into the finished bamboo charcoal.

  The bamboo charcoal soil improvement accelerator according to the present invention is obtained by cutting bamboo grown for 2 to 5 years and drying it for about half a year with a crusher. By soaking in diluted seawater for 1 day (2 days in the case of bamboo), it is possible to absorb more abundant iron and mineral nutrients contained in seawater than the method of including seawater in bamboo itself. . After that, draining and drying for about 5 days can shorten the time to make bamboo charcoal in the carbonization furnace. Furthermore, by mixing 1 to 4 times the bamboo vinegar liquid with the baked bamboo charcoal at a high temperature, the rich nutrients contained in the bamboo vinegar are added, and by increasing the specific gravity, it is dissipated in the wind and rain water. It becomes difficult to spread, spread evenly on the cultivated land, and easily mixed with the soil, and the effect as a soil improvement accelerator is enhanced.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a flowchart showing a method for producing a bamboo charcoal soil improvement accelerator according to the present embodiment.

  First, in F11, the harvested bamboo is dried for about half a year. From the viewpoint of easy carbonization, bamboo grown for 4 to 5 years with a moisture content of 15 to 20% is optimal.

  Then, it grind | pulverizes with a commercially available bamboo grinder by F12. The size of the pulverization is preferably adjusted to 10 mm or less from the viewpoint of easy mixing with the soil and less outflow, and easy dispersion.

  It should be noted that there is no particular difference between the above-described F11 step of drying bamboo and the step F12 of pulverizing the dried bamboo with a pulverizer, but considering the drying place, it is better to pulverize first. Cost is saved without taking up space.

  Next, in step F13, the bamboo material crushed in F12 is immersed in seawater for about two days. At this time, when the moisture content of the bamboo material is 20% or more, the penetration rate of seawater is low, which is not desirable. It is desirable that the concentration of seawater to be contained is about 0.35% heavier than the seawater 1 in order to take in as much nutrient as possible in the saltwater, and diluted with water 10 with respect to the seawater 1.

  Next, in F14, the bamboo material containing seawater is drained and dried for about 5 days.

  Next, in F15, it is put into a carbonization furnace for bamboo to make bamboo charcoal. The temperature of the furnace is carbonized at 200 to 750 ° C.

  Next, in F16, the bamboo charcoal carbonized in F15 is mixed with the bamboo vinegar liquid with a mixer at a high temperature. The bamboo vinegar liquid to be added is 1 to 4 times the weight of bamboo material 1 crushed with F12. When spraying on a field, the weight ratio is generally 1 to 1.5 times the weight, but in orchards, etc., when digging a groove around the fruit tree and sowing, it should be 4 times the weight. The effect of bamboo vinegar is enhanced. In addition, for paddy fields, when soil is added to bamboo vinegar, the apparent specific gravity of the soil improvement accelerator further increases and the outflow due to floating can be suppressed.

  In F17, the bamboo charcoal soil improvement accelerator of the present invention is completed.

Another embodiment 1

  F18 is characterized by being provided with a step of mixing raw seaweed crushed to 1 mm or less in place of the step of immersing F13 in seawater. As for seaweed to be mixed, Aosa, Mozuku, Arame and Chromo are suitable. The ratio of the seaweed to be mixed is suitably 0.1 to 0.5 seaweed with respect to the bamboo material 1 pulverized at a weight ratio regardless of the type of seaweed so that the bamboo chips can be successfully entangled (attached).

Another embodiment 2

  F13 and F18, that is, a process of mixing both seawater and seaweed together, is characterized by being manufactured. The mixing ratio is 0.1 to 0.5 seaweed with respect to the ground bamboo material 1 by weight.
