JPS5829052B2 - vegetable hydroponic cultivation method - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for hydroponic cultivation of vegetables such as honeysuckle and spinach.

Conventionally, in such hydroponic cultivation of vegetables, when the seedlings grow because they are grown in the same hydroponic container, the seedlings come into close contact with each other and their growth gradually deteriorates.

Therefore, when the seedlings were allowed to grow larger, it was necessary to pull them out one by one and replant them on the ground, which sometimes caused damage to the roots of the seedlings.

The present invention aims to solve these problems and to grow seedlings rationally and effectively.

Examples will be described below.

First, in the first step, vegetable seeds are spread and grown on urethane foam in a hydroponic container.

In this case, the urethane foam is impregnated with a culture solution, and slits are provided in advance so that it can be separated into units of appropriate size, for example, 2 cm square.

That is, in FIG. 1, 1 is a hydroponic container, 2 is a polyurethane foam corner, 3 is a slit, and 4 is a seedling.

The slit 3 may have an appropriate depth, and the important thing is that it can be easily separated into polyurethane square units.

Once the vegetable seedlings have grown to a certain extent in this way,
As a second step, the seedlings are transplanted into another hydroponic container as polyurethane cornices.

FIG. 2 is an example for explaining the second step.

In the figure, 6 is a hydroponic container, 2 is the polyurethane corner of FIG. 1, and 5 is bedding.

Floor cotton is natural or artificial cotton impregnated with a culture solution.

The polyurethane horns 2 that hold the seedlings 4 are placed on the bedding at appropriate intervals, so that the seedlings can fully grow without being in close contact with each other.

According to the present invention, the roots of the seedlings grown in the first step can be transplanted without damaging them.

In addition, the roots of vegetables that have grown in each polyurethane corner will penetrate into the bedding, but when the seedlings grow and become dense and you want to move and relocate the mutual polyurethane corner again, the roots protruding from the underside of the polyurethane corner will In some cases, it is sufficient to cut the roots leaving only a few millimeters.In this way, simply place the polyurethane square units on the floor cotton as needed, and use the polyurethane corner's good adhesion to the floor cotton to attach the polyurethane square unit to the floor cotton. Since the distance between the corners can be set at any time as needed, adjacent vegetables can be grown without intertwining, making it possible to rationally mass-produce vegetables at the required growth level, which has the effect of increasing work efficiency. Also, when it is necessary to use these vegetables for food, the roots can be easily pulled out of the bed cotton as polyurethane square units, so by lifting each polyurethane square unit, a single bundle of vegetables can be obtained. Therefore, there is also the effect that there is no need to bundle the vegetables again.

In this way, according to the present invention, it is possible to rationally and effectively grow vegetable bundles, and at the same time, there is an advantage that the vegetables can be sold as half vegetables in the second step.

Claims (1)

[Claims] 1 In the first step, slits are provided in the hydroponic container to form polyurethane corners of an appropriate size, and the vegetable seeds are scattered on a urethane foam impregnated with a culture solution, and the vegetable seeds are allowed to germinate and grow into seedlings of an appropriate size. Then, in a second step, a polyurethane square holding the germinated and grown seedlings is transplanted onto cotton bed impregnated with a culture solution in another hydroponic container and grown.
