Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a plant implantation material, that is, a culture medium material for horticulture, and a method for producing the same.

(Prior Art) Conventionally, sphagnum moss has been mainly used as a material for implanting plants such as orchids and foliage plants. However, domestic production has not been able to keep up with the increase in demand, and it is already exhausted, and most of them rely on imports from New Zealand and other countries. However, these foreign-made items are in short supply, their quality is declining, and prices are rising sharply. In addition, sphagnum root rot due to excessive humidity (excessive water retention) and decay over time (non-durability)
Since there are instability factors such as moss and moss troche (pest damage), it is difficult to control watering and new replacement is required at the time of replanting, which also causes shortage of goods and soaring prices.

(Problems to be Solved by the Present Invention) In view of the shortage of sphagnum moss and the difficulty in characteristics as described above, the present inventors have satisfied the physical and chemical conditions as an alternative and as an implant material. I have been searching for materials for several years. And as a result of that, we focused on cedar and cypress bark, which are abundant as waste from sawmills, etc., processed it into feathery strips, supplemented with liquid fertilizer of an appropriate concentration, and was not only a substitute for sphagnum moss. Therefore, it is an object of the present invention to provide an implant material that is easy to control water retention, is not affected by pests, and has excellent durability and stability.

[Structure of the Invention] (Means for Solving the Problems) The present invention has been made to achieve such an object, and relates to the following manufacturing methods and product structures for plant implant materials. That is, the bark of cedar is washed with water, the water content is adjusted to about 50%, the feathers are crushed with a crusher, and then this is impregnated with liquid fertilizer to supplement the fertilizer such as nitrogen. And a plant implant material obtained by the production method.

Also, after washing the cedar bark with water to a water content of about 50%, pulverize it with a pulverizer into feather-like fine pieces, then impregnate this with liquid fertilizer to supplement the fertilizer components such as nitrogen, and then dehumidify this. A method for producing a plant implant material obtained by drying, and a plant implant material obtained by the production method.

Also, the bark of Japanese cypress is mixed with the bark of cedar, and after washing this with water, the water content is adjusted to about 50%, and then crushed into feather-like pieces with a crusher, then impregnated with liquid fertilizer and nitrogen etc. The method for producing a plant-implantable material obtained by supplementing the fertilizer component of, and the plant-implantable material obtained by the method.

Furthermore, the bark of Japanese cedar is mixed with the bark of Japanese cedar, which is washed with water to a water content of about 50% and then crushed into feather-like pieces with a crusher, which is then impregnated with liquid fertilizer to remove nitrogen etc. The method for producing a plant-implanting material obtained by supplementing the fertilizer component of 1. and further dehumidifying and drying it, and the plant-implanting material obtained by the production method.

(Example) An example of the present invention will be described below by selecting bark of cedar as a material.

First, the long bark of the bark of the cedar peeled from the raw wood is shortened by a crusher (primary treatment), and this is mixed with the original short bark to be used as a feedstock.

Then, water is sprayed on this raw material by a spraying device to wash away the soil and sand adhering to the bark, and its water content is kept at around 50% in order to increase the permeation rate in the subsequent liquid fertilizer impregnation.

Then, this is crushed into feather-like fine pieces by a crusher such as a hammer crusher.

That is, the coarse bark that has been stripped from the raw wood is a relatively fragile cork layer on the surface layer, the middle layer of the fibrous and tough bark portion,
Since it is composed of the formation layer of the inner part that is in contact with the wood part, the material will be uneven depending on the part simply by cutting it with a knife etc. into chips, the water retention is poor, and the adsorption of plant roots is not good Due to the size of the feathery strips, the length is approximately 5 to 50 mm and the diameter is 0.01 to 5.0 mm in order to satisfy various conditions such as water retention, air permeability, plant adsorption, and handling management. Occupy most of it and remove fines.

Finally, liquid fertilizer is added to this.

That is, when the present inventors directly used the medium without supplementing the fertilizer, it was found that the plant undergoes a nitrogen starvation phenomenon at the beginning of planting, the growth is inhibited, and the plant is dead.

From this knowledge, P (phosphorus), K
(Kali), N (Chisso), etc.
(00 times to 2000 times) is impregnated with liquid fertilizer, and the feathery strips are put into the liquid fertilizer tank and soaked for 1 to 3 days, after which excess liquid fertilizer is removed with a drainer and the water content is about 60% to 75%. Alternatively, or as a simple method, an appropriate amount of the liquid fertilizer is sprayed on the feather-shaped strips, and the mixture is kept water for a certain period after stirring to obtain the implant material of the present invention.

Since it is inconvenient for transportation, storage and handling when it is wet with liquid fertilizer, it may be possible to temporarily dehumidify and dry it after impregnation with liquid fertilizer. And

Now, an outline of an apparatus for carrying out the above manufacturing method, that is, a process flow sheet is shown in FIGS. 1 (a) and 1 (b).

As shown in the figure, the raw material thrown into the supply hopper is subjected to sprinkling and washing on the way by the conveyer and sent to the crusher, and the pulverized feather-like pieces are blown by the suction fan into the cyclone. After being guided to a separator and sprayed with liquid fertilizer, the liquid fertilizer is sprayed and then put into a stirring tank, where the process is performed, and finally the product is drawn out from the discharge conveyor.

(Characteristics and Actions) The implant material obtained by the present invention is as described above. First, bark is used as a raw material and its form forms feathery strips. The workability is high because the columns are easy to stand up. The physical properties of the sphagnum moss and potting soil are shown below.

That is, although the weight of dried sphagnum is about 5 times that of sphagnum, when it is sufficiently moistened (excluding gravity water), conversely, sphagnum is 1.5 times heavier. Thus, per liter volume of planted material, sphagnum moss holds about 600 ml of water, whereas the implant of the present invention holds only half of it. On the other hand, the vapor rate does not change. Therefore, the material of the present invention has high water permeability and is a medium material that is easily dried. High water permeability means that salt accumulation due to continuous use of liquid fertilizer is unlikely to occur, and easy water drying means that brackish water can be controlled without fear of damage from excessive humidity. It can be said that it is the most suitable medium material in order to systemize irrigation by a drip irrigation system.

Next, since the water retention is low, it is easy to control the fertilizer, and it is possible to prevent the concentration trouble due to N (chisso) or the like. And this also acts as an indirect suppressing effect on the occurrence of disease. In particular, in the mode in which the bark of Japanese cypress was added, a strong antibacterial action by the oil / fat / hinokitiol was confirmed.

It should be noted that the N (chisso) starvation phenomenon due to the low fertilization property can be covered by performing appropriate fertilization as described above.

Furthermore, in the sphagnum moss medium, especially in the high temperature period, the surface layer is damaged by worms, the water permeability is deteriorated, and the environmental deterioration due to the generation of algae is brought about. Almost no worry of pests and diseases 5
Even after long-term cultivation for up to 6 years, it does not decay and its water retention remains unchanged. That is, the durability and stability are extremely large.

EFFECTS OF THE INVENTION The present inventors have accumulated a number of examples of use of the implant material of the present invention and obtained experimental results.
The test results for <Western orchid> are shown below in comparison with sphagnum moss and the like.

* We examined the growth results of a fermented strain of the third-year-old Cymbidium, which was fertilized by mixing a 1000-fold liquid fertilizer once every three times after planting.

As is clear from Table 2 above, the implant material according to the present invention showed the same growth as in the case of Sphagnum.

* Use a medium in which feather-like strips have been impregnated with liquid fertilizer in advance,
When seedlings of Western orchids were planted and the initial nitrogen starvation phenomenon occurred,
After that, the growth condition was observed.

Changing the N (chisso) concentration of the liquid fertilizer to be dipped depending on the type of western orchid, that is, N component of cymbidium.
Immersion in liquid fertilizer at a concentration of 0 ppm, N component of dendrobium, around 50 ppm, and N component of 30-50 ppm for Lelia produced good results.

* After planting Cattleya (MC363), irrigation and fertilization were repeated and the flowering state was observed.

As is clear from Table 4 above, it was confirmed that if irrigation and fertilization adapted to the characteristics of the medium were performed, flowering results that were not inferior to those of the existing moss were obtained.

The present inventors have continued cultivation demonstration for expanding the range of plants to which the implanting material of the present invention is applied, but in addition to the above-mentioned orchids, ferns Nephrolepis, Asiantum, pteris, asplenium, etc., and bromeliad , Beconia, Dracaena and other foliage plants have been confirmed to be suitable.

The bark, which is the material of the present invention, is an industrial waste produced from a sawmill, etc., and its processing is relatively easy. Even considering the cost of supplying liquid fertilizer, it is cheaper to mass-produce compared to the conventional sphagnum moss. Is possible.
