Abstract: front page image
(EN)Propagation and cultivation of freshwater and marine plants. These freshwater or marine plants are found naturally in underwater, floating or air-water interface habitats where sufficient illumination, nutrients and moisture are available to sustain life. A process is disclosed in which freshwater and marine macrophytes are cultivated in a water charged atmosphere, rather than in their native freshwater or marine environments, under precise control of such critical growing conditions as light temperature, nutrient supply and disease control. Carbon dioxide, a plant nutrient is introduced into the atmosphere or into the water while other nutrients are provided through the use of controlled mists or sprays arranged to maintain a film of nutrient containing freshwater or seawater on the growing plants. Natural waters may be periodically enriched with organic or inorganic nutrients. Significant improvement in harvest efficiency is realized by water charged atmospheric culturing of the marine and freshwater macrophytes, such that harvesting of the hydrophyte on a commercial basis is feasible.
(FR)Propagation et culture de plantes d"eau douce et salee. Ces plantes d"eau douce ou salee se trouvent naturellement dans des habitats sous-marins, flottants ou d"interface air-eau ou l"eclairage, la nourriture et l"humidite sont suffisants a permettre la vie. Un procede est decrit dans lequel des macrophites d"eau douce et salee sont cultivees dans une atmosphere chargee d"eau, plutot que dans leurs environnements naturels constitues par de l"eau douce ou salee, sous un controle precis des conditions critiques de croissance telle que la lumiere, la temperature, l"alimentation de nourriture et le controle des maladies. Du dioxyde de carbone, un aliment pour les plantes, est introduit dans l"atmosphere ou dans l"eau tandis que d"autres aliments sont fournis par l"utilisation de brume ou pulverisation controlee de maniere a maintenir une pellicule d"eau douce ou salee contenant des aliments sur les plantes en croissance. Les eaux naturelles peuvent etre enrichies periodiquement avec des aliments organiques ou inorganiques. Une amelioration sensible dans le rendement de la recolte est obtenue au moyen d"une culture atmospherique par eau chargee de macrophites d"eau salee et douce, ce qui rend possible une exploitation commerciale des cultures d"hydrophites.
