Description

The present invention is a hedera seedling breeding system for supplying a large amount and stably a hydroponic hedera seedling grown by a hydroponic cultivation technique, which is indispensable for greening of hedera by hydroponic cultivation, and Concerning the training method.

The greening of Hedera by hydroponic cultivation enabled the greening of sloped roofs and the entire greening of rooftops where objects are installed. However, because Hedera was originally cultivated in soil, when the present inventor realized greening by hydroponics for the first time, there was no idea at other places so far, and unprecedented technology was necessary for hydroponics. It was. In particular, Hedera seedlings used for hydroponics are the same species as those of soil cultivation, and the nature of the roots is completely different, and even if the seedlings of soil cultivation are transplanted into a hydroponics cultivation tank, they will not take root, Furthermore, greening by hydroponic cultivation of Hedera was not performed elsewhere because it was definitely root rot by many bacteria such as Fusarium bacteria contained in the soil.

  For this reason, in order to carry out hydroponic cultivation of Hedera, it is indispensable to grow hydroponic seedlings that match the conditions after planting from the cutting stage. The supply system has not been established, and there is a problem with stable and large-scale supply.

  In addition, in order to realize extensive greening as soon as possible at the planting site, it takes a lot of time just to wait for the extension of the hedera after construction. It was required that the seedlings to be long and durable.

In order to solve such a problem, the present invention enables a system that can cultivate Hedera seedlings for hydroponics at a large amount and at low cost and stably supply them. Such a Hedera The seedling raising system has never been seen before. However, the present inventor makes reference to transplanting of Hedera seedlings when performing rooftop greening using vines such as Hedera in hydroponics in Japanese Patent Application Laid-Open No. 2006-20542. I have not proposed until.

  In JP 2008-173093 A, when the present inventor transplants Hedera seedlings, if the roots of the plants are floating in a hydroponics cultivation tank, the plants are too stressed to inhibit growth. Therefore, it describes that covering the root of Hedera with a seedling culture medium such as a sponge in order to relieve stress.

  The present inventor, from the time of proposing rooftop greening by hydroponic cultivation of Hedera, based on the results of trial and error, Hedera for hydroponic cultivation is the same unless it uses seedlings grown for hydroponic cultivation Even if it is Hedera, since the nature of the roots is different between soil cultivation and hydroponics, it has been confirmed that planting and continuous cultivation are not possible, and then suggesting greening by hydroponic cultivation of Hedera Is. The proposal of the Hedera seedling breeding system and the breeding / planting method was made based on such facts, and this seedling raising technique is indispensable for rooftop greening by Hedera's hydroponics. .

  An object of the present invention is to cultivate a large amount of seedlings for hydroponics, which are necessary for hydroponic cultivation of Hedera, in a large amount and at low cost, and stably supply the seedlings.

  Set up one or more shelves in a greenhouse such as a plastic greenhouse, install multiple groove-shaped seedling cultivation pits, arrange seedling pots with cuttings of hedera, and leave one end of the cultivation pit. An aqueous solution is supplied from the other end, drained from the other end, collected in a drainage mother pipe, returned to the cultivation liquid tank, and the aqueous solution is circulated to stably grow a large amount of long-sized seedlings.

  The grown seedlings are transported by a dedicated Hedera packing box, planted in a hydroponics cultivation tank installed at the planting site, and replanted by Hedera hydroponic cultivation. Basically, both seedlings and greening are carried out by hydroponics that circulates an aqueous solution, which makes it possible to achieve extremely smooth rooftop greening.

  Since the present invention can cultivate and supply a large amount of Hedera hydroponic seedlings in a small place, it is excellent in economic efficiency and enables stable supply of seedlings regardless of the external environment.

It is a front view which shows the seedling raising condition in the seedling raising house of this invention. It is sectional drawing in the nursery house of this invention. It is a water pipe system diagram for circulating the aqueous solution of the seedling raising system of the present invention.

  The system for growing Hedera seedlings for hydroponics according to the present invention includes a single pipe or rafter in a cultivation house that is not directly exposed to rain and wind, such as a general plastic house. A shelf of steps is constructed, and a row or a plurality of rows of cultivation grooves (nurturing seedling pits) are arranged in parallel on each step to form a seedling cultivation tank.

  This seedling pit is installed with a gradient of about 1/150, supplied with an aqueous solution from one end, drained from a drain outlet provided at the other end, returned to the aqueous solution tank, and circulated the aqueous solution Thus, the aqueous solution can be supplied in a circulating manner while always maintaining a constant water level.

  The shape of the seedling pot is not limited, but a round pot having a diameter of about 100 mm or a size having a cross-sectional area equivalent to that is used so that the seedling can be grown to a length of about 2500 mm. The seedling pot is filled with a filler such as Hinata pumice, and the seedlings to be cut are cut with a sharp blade, cut off one hedera leaf from the root, and cut diagonally about 2 to 3 cm below that position. Fill the pot with Hyuga pumice until it reaches the top of the pot.

  When the seedling pots with cuttings of Hedera are lined up in the seedling pit without any gaps and the aqueous solution is supplied to the seedling pit, the bottom of the seedling pot is filled with the aqueous solution, and the aqueous solution also reaches the Hyuga pumice that is above the water level over time. In the best condition, it is preferable that the water level in the seedling pit is maintained at about one third to one half from the bottom of the seedling pot.

  It is desirable to arrange the seedling pots in the seedling pit with as little gap as possible. However, since there is no gap part, it is not possible to eliminate the gap part. It is convenient to attach a light-shielding vinyl sheet (pit cover) to both upper ends and wrap the nursery pits leaving only the Hedera seedlings that have been cut into the nursery pits.

Hedera seedlings should be carried out at a temperature of approximately 20 ° C or lower, so cuttings are preferably carried out from autumn to early spring. However, if it is necessary to select the timing, either an aqueous solution tank or a water pipe system Moreover, you may provide the water temperature adjustment apparatus which has the greenhouse equipment for maintaining the water temperature of a seedling pot to about 0-25 degreeC throughout the year, and a water temperature adjustment function. In addition, the seedling pits are not groove-shaped but may be a PVC pipe having a seedling pot installation hole.

The present invention will be described in more detail with reference to the illustrated examples, but the present invention is not limited to these examples.

FIG. 1 is a front view showing a seedling raising situation in the seedling raising house 1 of the present invention. The seedling racks and pit covers are omitted for the sake of clarity, but as shown in this figure, the seedling pots 2 in which Hedera is planted are closely arranged in the seedling pits 3 and placed in the water supply pipes 4 such as PVC pipes. An aqueous solution is supplied to the seedling pit 3 from the water supply hole 5 provided.

In the present embodiment, the seedling pits 3 are configured in two stages and two rows, but the amount of water supplied from the water supply hole 5 depends on the distance relationship between the position of the water supply hole 5 and the water supply pump 21 and the height relationship. By changing the size of the water supply hole 5, the hole at the far position is larger than the hole at the near position, and the hole at the high position is larger than the hole at the low position. The amount of aqueous solution supplied to each seedling pit is adjusted.

FIG. 2 is a cross-sectional view of the nursery house 1 of the present invention. In this figure, on the left and right of the central passage, seedling racks 11 are assembled in two stages with single pipes and the like, and a seedling pit is installed on the shelf, and the seedling pots 2 are arranged therein. The Hedera 8 cultivated in the seedling pot 2 is, for example, a drooping Hedera canariensis, which initially grows up, but as it grows it grows in a state of hanging down as shown in the figure due to its own weight. Become.

Of course, the nursery rack 11 may be a single stage, and a plurality of rows of seedling pits 3 may be provided thereon. Placement of seedlings that have been started later on a low shelf is advantageous because the seedlings can be taken out in order.

  FIG. 3 shows a water pipe system for circulating the aqueous solution of the seedling raising system. The aqueous solution sent out from the aqueous solution tank 20 by the submersible pump 21 is the water supply pipe 4 through the water supply holes 5 on the water supply side of the seedling pit. The aqueous solution that is supplied to the end and comes out from the drainage port 7 provided at the other end of the seedling pit is collected in the drainage mother pipe 6 and then returned to the aqueous solution tank 20 by the drainage pipe 9. When the aqueous solution in the aqueous solution tank 20 falls below a certain level, the level sensor 22 operates the makeup water valve 23 to supply water from the makeup pipe 24. In addition, the fertilizer concentration in the aqueous solution should be thin at the start of raising seedlings. Only after adding a rooting promoting solution such as commercially available Menedale, after about 3 weeks after rooting, the concentration of the aqueous fertilizer gradually increases. Good.

  Each of the long seedlings thus grown is covered with a waterproof bag together with the seedling pot, and stored and transported in a packing box equipped with a cushioning material such as sponge while being stretched horizontally. By doing so, a large amount of long seedlings can be transported and transplanted without damaging the seedlings, so that a wide range of greening can be performed at an early stage.

The present invention supplies a long seedling for hydroponic cultivation that is indispensable for realizing greening by hydroponic cultivation of Hedera, which is a completely new greening method, and is economical. And is extremely useful because it can stably supply a large amount of seedlings at an early stage.
