Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a medium for raising plant seedlings, which is made of powder and short fibers obtained by separating the interfiber tissue of the pulp of a coconut.

Traditionally, sieved soil has been used as the oldest medium for growing plant seedlings, but in recent years, beets, drainage, fine vermiculite with a particle size of 0.75 to 2 mm, perlite, and pumice have been used. , sand, mixtures of these, etc. are used. Furthermore, nutrients necessary for plant growth are added to these to make a mix for raising seedlings, or this can be wrapped in paper or coarse net, or it can be molded as is into pellets.

Each of these new seedling growing media has its advantages and disadvantages, but the common drawback is that they must be supplemented with nutrients necessary for plant growth.

The purpose of the present invention is to provide a better medium for raising seedlings.The purpose of the present invention is to separate the fibers of the pulp layer of a coconut from the tissue that fills the gaps between the fibers. They found that it not only enriches, but is also a well-balanced fertilizer, and they completed it by adding an appropriate amount of fiber to it and making it breathable.

The present invention will be explained in detail below.

Coconut fruits typically have a large central cavity surrounded by a hard core (shell), a fatty endosperm layer, and a clear liquid enclosed inside the fatty endosperm layer. There is a thick fibrous pulp layer on the outside of the kernel, and a thin pericarp on the outside. The part used in the present invention is the fibrous pulp layer, and the type of coconut is not particularly limited, but coconut palm etc. are preferable.

In producing the culture medium for raising seedlings of the present invention, the fibrous pulp layer after removing the coconut shell and the old matter inside the shell is appropriately cut and soaked in water to sufficiently swell the tissue. The swollen tissue is stirred, the fibers and interfiber connective tissue are peeled off, and the fibers are separated by scraping or sieving through a coarse sieve. After separating the fibers, the contents are left to settle, and the sediment is collected and dehydrated using a centrifuge or the like to obtain a powder. Fibers are added to this powder.

The fibers are used by cutting separated palm fibers.

Coconut fibers are particularly desirable because they improve air permeability, drainage, and are resistant to rot. Its length and amount give the powder air permeability,
It is sufficient as long as it can be mixed uniformly with the powder. Specifically 5
It is mainly composed of those with a diameter of mm to 2 cm, and there is no problem even if some of those outside this range are mixed in.

In some cases, synthetic or natural fibers derived from materials other than coconut may be used. For example, cut polyester fiber, palm bark, etc.

The seedling raising medium according to the present invention can be placed in a shallow box as it is to use as a seedbed, or shaped and wrapped in a net, water-absorbing and degradable bag, etc.
Use as an initial medium for sowing or raising seedlings for hydroponic cultivation. or,
It is also excellent as a support for irrigation cultivation. Furthermore, in the mericlon culture of Western orchids, etc., 1 germinated from the agar medium
Conventionally, when planting seedlings about cm in size, a water trap was manually wrapped around the roots one by one, but when planted in the seedling-raising medium of the present invention, the work efficiency is improved and the subsequent growth is good.

The present invention will be specifically explained below with reference to Examples.

Example 1 The kernel and its contents were removed from a coconut, and the pulp and skin were roughly crushed into about 4 pieces.

This was packed in a barrel, water was added to cover it, and the barrel was left for 4 hours.

After the tissue was swollen, it was stirred for 10 minutes at 60 RPM using a stirrer with stirring blades having multiple claws to separate the fibers trapped in the claws and air-dried.

The remaining liquid was allowed to stand for 3 hours, the reddish-brown supernatant liquid was poured off, and the sedimented portion was centrifugally dehydrated to obtain a slightly moist powder.

When this powder was analyzed, the fertilizer components contained in the dry ingredients were 0.14% by weight of nitrogen (as N) and 0.14% by weight of phosphorus (P=Os).
) 0.05% by weight, Potassium (as K2O) 0
．． It was 0.8% by weight. When 500ml of water was added to 5g of this product, p)l at 15°C was 7.0.

The entire amount of this powder was mixed with the fibers that had been previously scraped and air-dried and cut into an average length of 1 cm to form a seedling growing medium.

Example 2 The seedling growing medium obtained in Example 1 was spread lightly to a thickness of about 5 cm, and seedlings of about 1 cm that had germinated on the agar medium by mericlon culture of Cadrea were implanted with pins. Compared to the conventional method of wrapping the water trap around the radicle, it is only necessary to insert it, so the amount of work for one person was reduced to 700 yen.
This has increased from 2,800 bottles/day to 2,800 bottles/day.

Both plants were cultivated at the same time using the medium of the present invention and a water basin under the same conditions except for the medium, and their growth status was compared after one year. It was excellent.

Example 3 The seedling growing medium obtained in Example 1 was used for irrigation cultivation of tomatoes. The culture medium of the present invention is compressed to a diameter of approximately 4 cm and a height of 3 cm.
pellets were produced. The pellets were sufficiently soaked with water, seeded in the center of the upper surface, and arranged on a grid-like shelf. They soon germinated and roots grew through the pellet. A water channel was formed under the lattice shelf, and a cultivation solution containing dissolved nutrients was passed through this channel for 45 minutes, and the water flow was stopped for 15 minutes. This operation was repeated constantly using a timer during cultivation, and good results were obtained.
