Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a soil for cultivating potted ornamental plants such as lily and chrysanthemum.

[Conventional technology]

Conventionally, the cultivation soil used for flower pots for orchids, chrysanthemums, ornamental plants, etc. has been made of drained water, hadroculture Kanuma soil, pumice, and the like. Water drains not only limit raw material resources, but also rot in two years, so orchids must be replanted every year. Generally, it has the disadvantage that it requires replanting three times before it blooms, which is time-consuming.

In Japanese Patent Publication No. 63-52848, the present inventor proposed a plant planting material made from coconut pulp that can be used both as potting soil and as a soil conditioner. The material for this implant is a chip obtained by pressing the pulp of a coconut almost perpendicular to the fiber arrangement direction and then cutting it.The pressed pulp of the coconut expands and contracts depending on the amount of water. Repeatedly, it has excellent heat retention, water retention and fertilizer retention,
It is difficult for pathogens to grow. In addition, it is an excellent cultivation soil for orchids, as it is resistant to rot, so even if orchids take three years to bloom, there is no need to replant them during that time.

[Problem to be solved by the invention]

However, the implantation material disclosed in Japanese Patent Publication No. 63-52848 had some difficulty in drainage, and also had a pH of about 5.5, which tended to be acidic. An attempt was made to improve drainage by adding pumice, but it was discovered that pumice has poor heat retention and has the disadvantage of halting the growth of plant life, especially in the winter. Furthermore, when the room temperature drops, the temperature of the cultivation soil also drops quickly, requiring special attention to temperature control in winter.

The purpose of the present invention is to provide a potted cultivation soil that has an ideal pH value, has good drainage properties, and allows roots to grow thickly and actively.

[Means of problem solving]

The present invention solves the above-mentioned problems, and its composition is obtained by pressing 40 to 95 parts by weight of coconut seed husks and coconut pulp almost perpendicularly to the fiber arrangement direction, and then cutting it. It is characterized by containing 5 to 30 parts by weight of dried chips (calculated on a moisture content of 14%) and 2 to 15 parts by weight of vegetable charcoal.

In the present invention, the pulp part of a coconut is the porous pulp part and pericarp that remain after seeds and seed shells are removed from the coconut. There is no need to remove the peel since it is peeled. In the present invention, it is first necessary to press the pulp part of the coconut.

The direction of pressing is almost perpendicular to the direction in which the fibers are arranged,
When pressed in this direction, the distance between the fibers is simply reduced, and no force is applied to cut the fibers. Therefore, it is not necessary that the angle be exactly right; it may be approximately a right angle as long as the fibers do not break or bend. Pressure rate is 1/2 to 1/10
When the pressing force is removed, the thickness returns to 70-80% of its original thickness.

The pressed pulp is cut into granules or chimps. The chips obtained in this way may be used as the cultivation soil for potting plants of the present invention as they are, but if they are soaked in an equal amount or more of water for one day and night,
After removing the reddish-brown water that leaches out, a more preferable cultivation soil can be obtained by blending it with other ingredients. When the pulp chips absorb water, they expand and have high water and fertilizing properties, as well as buffering properties against temperature. Even when the surrounding temperature drops, the temperature of the cultivation soil slowly decreases, making temperature control easy.

Coconut seed shells are the so-called husk, which forms the inner layer of the pulp, and is a dense layer that encloses the liquid endosperm, and is the most excellent raw material for activated carbon. When this coconut shell is cut into chips and incorporated into the cultivation soil of the present invention, drainage is improved without hindering root growth, and there is no risk of root erosion.

The charcoal of plants is a type of charcoal, which is obtained by roasting plant tissues, preferably coconut shells, at about 800°C. In particular, carbonized coconut shells neutralize the acidity of coconut pulp at a pH of about 9, making it suitable for adjusting the pH of the entire cultivation soil. Carbide also has the effect of preventing roots from being uprooted.

The present invention requires that each of the above components be blended in appropriate proportions. That is, 40 to 95 parts by weight of coconut shell, 5 to 30 parts by weight of pulp chips, and 2 to 2 parts by weight of carbonized plant material.
It is 15 parts by weight. Preferably 50 to 90 parts by weight of coconut shell, 7.25 parts by weight of pulp chips, and 3 to 1 parts of carbonized plant material.
This is the O heavy foot part. Because pulp chips have a small bulk specific gravity,
Apparently, it is acceptable to mix approximately equal amounts of coconut shell and pulp chips. In addition, since the water content of pulp chips varies somewhat, the above values are expressed as a water content of 14%.

In addition to the above ingredients, the present invention also includes fertilizers used for plant cultivation,
Plant hormones and other ingredients can be added.

[Effect]

In the present invention, after pressing the palm pulp in a direction perpendicular to the fibers,
It is made by blending pulp chips obtained by cutting, coconut shells, and charred plant matter, adjusting the balance between water retention, fertilizer retention, and drainage, and adjusting the pH to a neutral level. Also,
Since we use Sogetsu, which is hard to rot, it is possible to cultivate strawberries etc. without replanting for more than 3 years. Coconut shells and carbonized plants are plant-derived materials that have good affinity with roots and can help grow thick and strong roots.

〔Example〕

3 to 4 pulp layers from coconut fruit with seeds and seed shells removed
The pieces were divided into pieces and pressed approximately 1/5 at right angles to the direction in which the fibers were arranged, and the pieces were cut into pieces of approximately 1.5 cm square to produce pulp chips. Thirty parts by weight (moisture 14%) of this chip was immersed in twice the amount of water for one day and night, and the reddish brown supernatant water was removed. This operation was repeated twice to drain the water and obtain the A component.

150 parts by weight of wedge husks are crushed into particles with a diameter of 5 cm to 1 cm,
It was designated as component B.

Diameter 5mm ~ lc obtained by roasting coconut shell at 800℃
The granular carbide of m was used as the C component.

The above A component, B component and C component were mixed to obtain the cultivation soil of the present invention. ” The bulk specific gravity of each component is 45% for component A and component B.
The ratio was 50% for the component and 5% for the C component. Also, pH
was 6.8.

Cattleya seedlings obtained on an agar medium by Mericlon culture were transplanted to a seedling growing medium consisting of fibers of 1 to 2 cm in length obtained from palm pulp and powder or granules, and liquid fertilizer was applied. He acclimatized for about three months while undergoing treatment. Transfer this seedling to 3 above.
They were transplanted into pots using cultivation soil mixed with ingredients, and grown using conventional methods of watering and fertilizing while heating during the winter. The roots of this seedling were thick and fully developed, and flower buds appeared in two and a half years.

Separately, cattleya seedlings were acclimated in the same manner as in the above example.
The plants were grown in the same manner as in the above example, except that a cultivation soil consisting only of palm pulp chips and a water basin were used. In both cases, it took three years to produce flower buds, and the flower color was slightly inferior. In the case of water, the flower color was poor and it was necessary to repot it every year.

〔effect〕

The cultivation soil of the present invention has good water retention, drainage, and fertilizer retention ability, has an ideal pH of 4fi, and is resistant to rot, so that the buds grow thick and strong, and there is no need for replanting, making it possible to efficiently use high-quality orchids. can be cultivated. Therefore, in conventional orchid cultivation, it took three years to produce flower buds, but the present invention can shorten the time to two and a half years.
