DE2935957A1 - Floating plant cultivation system - uses buoyant tanks floating on water and containing nutrient solution - Google Patents

Abstract

The water-plant cultivation system, for rice etc., uses tanks containing a nutrient solution. The tanks are buoyant, so that they float on sea, fresh or brackish water, allowing the surface of the latter to be utilised, e.g. for atolls and small islands. Corrosion-resistant non-transparent sheet, stiffened at intervals by transverse bars, can be used to support sieve trays containing seeds or plants, sliding into U- or L-section rails on the tank.

Description

Designation: S c h w i m e n d e H y d r o k u l t u r

B e s c h r e i b u n g m i t P a t e n t a n s p r u c h hydroponics are in containers (tanks) made of ceramic, plastic, glass, impregnated wood, metal etc. operated, which are filled with a nutrient solution. The nutrient solution is common a solid buffer substance (gravel, expanded clay, etc.) is added. No indication n d for my invention is the appropriately prepared tanks in sea, brackish oaer fresh water to swim in order to create extensive, partly life-poor water areas to make them usable for plant culture. This could be done on the surface of atoll lagoons in the central Indian Ocean, where a usable biomass of less than 2oog / sqm generated in the year, with the floating hydroponics a usable biomass (e.g. rice) of l.7oog / sqm per year.

The main item of floating hydroponics is one with usual nutrient solution adapted to the plant species to be grown, more filled, more buoyant Tank made of plastic, metal, impregnated wood, lightweight concrete, lightweight ceramic or other material. The nutrient solution can be a light buffer substance, e.g. Expanded clay, to be added. The plastic tank can be made from a compact or foam plastic shell exist; Furthermore, plastic films can be used for the tank skin supported by a frame made of plastic, wood, bamboo, metal, glass or ceramic will. Instead of the scaffolding, inflatable chambers worked into the film can be used wear the tank skin. Unless algae are to be cultivated, the tank skin must be opaque.

In the experiments I carried out, foil tanks with scaffolding were used Made of wood, bamboo and plastic as well as plastic shell tanks are used, according to the Nutrient solution tank is another important component of the floating Hydroponics the culture medium, i.e. the facility in which the plants can tangle and the green part of the plants above the nutrient solution holds. In the course of the experiments, one was equipped with stiffening rods nontransparent film turned out to be particularly suitable.

The stiffening rods carry seed / plant sieves - small, open at the top Plastic containers - the bottoms of which are covered with root holes. Usually flank (and carry) 1 pair of Ve @@@@ un @ rods a row of seed / plant sieves. The use of this carrier film makes the presence of insert or

D o u t o u p e p i n e l: Made of PVC pipes (for culture harmlessness pay attention!) from 25mm # are two closed, rectangular frames with the side dimensions @ s @ @ 12 @ cm (see drawing nos. 1 and 2). By inserting a total of 4 PVC pipe pieces (3) of the same @ t @ r @ r @ @ oc @ length becomes the frame spacing fixed at 20cm.

The pieces are at two corners separated from each other as well as in in the middle of the long straight line. The frame (1) that is now at the bottom will be stiffened in the middle of the long straight with another piece of pipe of 120cm Linge. Customer is a PVC @ real corner @t @ side outside dimensions of 80 x 125 cm - @@@@ r. This Ve @ @@@@ ahmen (4) is not stiffened with pipe pieces on the double frame The end is pre-welded in such a way that the lower 105cm straight line of the attachment frame meets the lower 125cm- @ @er @ elrahmens covers. The two @ oc @ straight meet at a height of 25cm the attachment frame on the corners of the upper part of the @@ @l e @ and are welded @ort. A # -rail (@) is now placed on each of the two @ n l ra @@ n of the double frame fixed in such a way that its 2 cm wide opening is towards earthen. The # rail is only 350cm long and leaves 50cm of the @@ @n frame free inside the attachment frame. The framework of a T nen-T @ @ is now finished.

The sides, the bottom, the back and the attachment frame will now with non-transparent, non-toxic, UV-resistant, corrosion-resistant Foil coated on the outside, with which the middle tank (inner tank) is ready for use. The middle tank should be the normal version in large-scale applications - on 60 to 120 medium tanks there would be 2 of the side tanks to be described now.

The side tank differs from the middle tank in that it has the side facing away from the middle tank on the # -rail a vertical additional frame 53cm high, which is seamlessly connected to the attachment frame. The foil is also raised up to 80cm on this side.

For this exemplary embodiment, there are 2 middle tanks and 2 side tanks to be made with additional frame on the right and 2 side tanks with additional frame on the left. the two middle tanks are glued together with the 25cm high rear panels. Now there is 1 side tank with an additional frame on the right with one that holds the additional frame carries on the left, glued on the back. The two pairs of side tanks can be connected to the Middle tank pair glued in such a way that they flank this appropriately. So is a tank group was made, surrounded by an 80cm high foil wall from the wave effect is protected. In order to perfect this protective effect, the connection points are the side tank pairs to be covered with foil 8ocm high.

After gluing the tank group together, holes must be made in the inner ones Side walls of the tanks are cut to ensure an even distribution of nutrient salt in the entire tank content of a group.

The tank battery (group) is then placed in a seawater pool inside of a wet plant greenhouse @.

Now make 3 carrier foils (6), each 8 m long and 124 cm wide. The material used is about 0.0 mm thick, nontransparent, culturally harmless, UV-resistant Plastic film (e.g. special LKOR-PVC, BEMBERG-W-resistant polyethylene or similar). At a distance of 1Ucm (from center to center) there are 50 pairs Stiffening rods (7) attached in the transverse direction below the film.

The distance between the last pair of rods and the end of the film is 8 cm. the Stiffening rods are 15mm high and 8mm thick and are made of dimensionally stable hard plastic. A pair of rods flank and carry each 5 7 seed / plant sieves (8) that keep a distance of 18cm (center to center) from each other. The respective distance to the edge of the film is 8cm. The seed / plant strainers are box-shaped, upwardly open plastic container with a base area of 20 x 35mm and 28mm high. There are about 30 root holes each in the bottom of the sieve Stamped into the opening. A cellulose packet (itterial, how it is used for the production of the commercially available seed carpets), in the white seeds (e.g. Oryza sativa japonica) were sewn, with culturally unrelated Special glue that dissolves in the nutrient solution after a few days, glued. from Experience shows that the 6 seeds develop on average 5.5. Per carrier film this results in 1925 plants, so that each plant has an area of 52 square centimeters stands. Before the carrier films are attached, the tanks are filled with nutrient solution about 3mm below the lower edge of the # -rail. Either will be the water so much commercially available (e.g. LUWASA) nutrient concentrate is added that one concentration of o, 5 yo arises, or else the tanks are filled with nutrient batteries accordingly (from LUWASA et al.).

With: Foil of handle ropes made of rot-proof plastic that attach to are attached to each end of the film, the carrier film is now over the nutrient solution level after being previously inserted into the UL rails.

With the appropriate air temperature (about 25 - 300C) and humidity (over 85%) the Xeis germs emerge from the cellulose packet on the 5th or 4th day. After about lo days, the nutrient solution concentration is increased to o, 75, Óo by careful Refill concentrate under the slightly raised carrier film near the Increased attachment frame.

The concentration is increased to 1% in the same way on the 15th, to 1.25% 0 on the 20th and to 1.5 thousand on the 25th day. The rice now has a height reaches an average of 25cm. When using nutrient batteries is to the end nutrient salts are not required during the growing season. In the other In this case, after a further 60 days, approximation in values of 0.35% 0 is necessary, whereby it is important to ensure that a particularly large amount of nitrogen, e.g. in the form of ammonium nitrate. The ice ripens after about 150 days (from of germination). It is easily attacked by rust and harmful insects. You must therefore regularly with insecticides (e.g. UNDEN) and fungicides (e.g. EUP@REN) splash.

The experiment is completed after the harvest.

A developed concept for large-scale application in tropical areas is available,
