JPH07110181B2 - Method of root growth of mycorrhizal tree - Google Patents

Description

TECHNICAL FIELD The present invention relates to a method for growing roots of a mycorrhizal tree such as red pine that grows matsutake mushrooms, and particularly for increasing the number of fine roots.

[Conventional technology]

Generally, as a method of growing roots of plants, a method of applying compost or organic fertilizer or chemical fertilizer has been conventionally adopted.

[Problems to be Solved by the Invention]

Among the above methods, the method using the most frequently used organic chemical fertilizer is not suitable for roots of mycorrhizal trees such as pine mushrooms because it promotes the activity of bacterial fungi and is weak against bacterial fungi. .

On the other hand, in consideration of the recent root growth failure of mycorrhizal trees, the cause of acid rain caused by exhaust gas cannot be ignored.

As an experiment, it is considered that acidic water mixed with automobile exhaust gas is made to permeate into the soil and black spots are attached to the root and the soil surface, and the attached matter inhibits the assimilation action of plants.

If 10 l of water is put in a container and the diesel engine is mixed in water at a slow speed for about 10 minutes to dissolve the exhaust gas, the water in the container will be about pH 3.0.

And if left as it is, many black spots will settle,
The spots were like soot of a chimney, and were the same as those attached to the soil surface or root.

That is, the exhaust gas scattered in the air adheres to the trunks or roots or leaves of plants, is washed away by rainfall and is filtered to the ground, and the filtered material adheres to the roots or shallow roots and inhibits root development. Of.

Therefore, the present invention aims to promote root growth by neutralizing the deposits due to the exhaust gas.

[Means for Solving the Problems]

The present invention is characterized in that the ionic decomposition solution obtained by energizing water containing a mycorrhizal tree to be developed is sprayed to the root to promote root growth.

[Action]

The ionic decomposing solution is alkaline, has the effect of neutralizing acidic substances due to exhaust gas, does not have the activity of bacterial fungi, and has the same characteristics by using mycorrhizal trees that are to be developed. To use.

〔The invention's effect〕

INDUSTRIAL APPLICABILITY The present invention has the effect that an ionic decomposition solution of the same mycorrhizal tree prevents excessive acidification of the mycorrhizal tree and promotes root development. When the root grows and the number of fine roots increases, the number of branching points of the root to which the mycorrhizal fungus adheres increases, and the number of adherent mycorrhizal fungi increases. Furthermore, it is also effective for soil improvement.

〔Example〕

The pine tree is cut with an electric planer to form a chip, and the chip
A tank containing 600 liters of water is placed in the central compartment where the wall of porous material is disassembled into two parts, and positive and negative electrode plates (DC power) are placed in the other compartments, 100V, 20A
The above was poured and electrolyzed for about 10 hours.

Then, the chip-shaped pine components in the central compartment are electrolyzed into positive and negative ions, and the positive electrode compartment contains the active ingredients containing negative ions, and the negative compartment also contains negative ions. Is an active ingredient containing positive ions that passes through the wall of the porous material and is extracted and dissolved in the water in each compartment.The compartment of the positive electrode plate is PH3.4, and the compartment of the negative electrode plate is An ion decomposition solution of PH10.4 was obtained. The results are shown in the table below as a result of mixing the two solutions, adjusting the pH to 5.6, and watering the roots of the pine trees once a week.

It has been proved that if the soil is strongly alkaline, large matsutake mushrooms can be obtained, but the number is small, and if the acidity is strong, many small matsutake mushrooms are obtained.

Therefore, in consideration of product value and economic efficiency in terms of quality and quantity, PH5 is used as a soil condition to obtain a considerable number of matsutake mushrooms on a medium scale.
Since it was set to 6, PH should be corrected according to the quality and quantity of pine mushrooms to be raised.

For watering, the amount of watering and the time of water supply may be determined so that the soil around the roots can always keep wet.

Since the roots of mycorrhizal trees are shallow roots, the ion decomposition solution directly acts on the roots together with soil improvement, and if the balance of sunlight, water, temperature, humidity, etc. is maintained, even better results are obtained.
