Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for growing seedlings for hydroponic cultivation, and is particularly suitable for growing tap-rooted vegetables.

Water [Urethane or other suitable foaming agents are used as a seedbed when raising all the seedlings for cultivation. In this case, vegetables such as lettuce, mustard greens, green onions, etc. will germinate and grow simply by sowing the seeds on top of the urethane because the squares penetrate into the air bubbles of the urethane. In plants, Vce cannot be found in the urethane bubbles (
(Narudame seeds with floating roots are sown in all-urethane soil and will germinate but will not grow.

As a means to germinate and grow tap-rooted vegetables using all urethane, make a full cut in the urethane and place each seed inside the cut. It is conceivable to press it, but this requires a lot of effort and time, and the workability is also poor, and in reality, mass production for commercial use cannot be done using this method. Even if this were possible, since urethane is water-absorbent, the pericarp of the seeds would absorb the water contained in the urethane, resulting in excess moisture, which would cause the seeds to lack oxygen and cause poor germination. There is also.

For this reason, it has traditionally been considered impossible to hydroponically cultivate tap-rooted vegetables for commercial use.

Therefore, the inventor of the present invention made every attempt to spread soil on top of the seeds sown in the urethane layer. As a result, the seeds are starved of oxygen, causing poor germination, and the soil contains bacteria, which causes problems such as the inability to fully use hydroponic cultivation, which requires sterile cultivation. Atsu/ko.

The present invention was developed as a result of such research,
A urethane or other similar foamed phase is used as a seedbed (1), and directly on top
(2) Sow all the seeds in bulk, and then cover with a covering material f3) that has a suitable water retention property and is sterile. e.

As the frame material (3), it is inappropriate to use a material that retains too much water or a material that has too large particles; it is suitable to use a material that has a moderate water retention capacity and is sterile. These include, for example, rice grain smoked charcoal and perlite tongue. The covering materials (3) of J'l et al. can be used alone or mixed for at least 2 seconds, and a1! Cover it so that it is about 3 times as thick as the layer (1).

As a result, seeds 1 to 21 are placed in a suitably dark and sterile cultivation environment so that the seeds are completely prevented from drying out, as well as from becoming overly hydrated, and the seeds are supplied with oxygen.

As shown diagonally above, the present invention is made of water-absorbing synthetic resin seedbeds (11) with water-retaining properties suitable for seeds (2) of tap-rooted vegetables sown in seedbeds (11). 'i9 Let Seeds (
2) Seeds (2) All nursery beds (11 Not only will germination occur just by sowing in a row, but even after the tap roots emerge, adequate water retention and oxygen supply are carried out, so even if the tap roots in a row become floating roots, they will not germinate. Therefore, the lateral roots coming out from the tap root penetrate into the seedbed +1.1 and spread the roots completely, and then the fully grown tap root gradually grows from the air bubbles and cracks in the seedbed (1). Since it becomes possible to invade the seedbed (1), tap root vegetables can be grown, and their hydroponic cultivation becomes possible.
