20.500.12556/RUL-161853 Vpliv hidroponske pridelave na pridelek in kakovost žlahtnega jagodnjaka (Fragaria ananassa) The influence of hydroponic cultivation on the yield and quality of cultivated strawberry (Fragaria ananassa) Hidroponika je tehnologija pridelave rastlin v hranilni raztopini, ki se v zadnjih letih vedno bolj uveljavlja zaradi prednosti, ki jih lahko prinaša, kot so na primer nižji stroški pridelave, manjša poraba vode in večja vsebnost bioaktivnih snovi v plodovih. Poleg zelenjadnic in okrasnih rastlin je hidroponika zanimiva tudi za nekatere razširjene sadne vrste kot je žlahtni jagodnjak. Znanih je več različnih hidroponskih tehnik, pri pridelavi jagod pa je najbolj pogosta tehnika gojenja na kameni volni (rockwool culture) in drugih organskih in anorganskih rastnih substratih, kjer gre za zaprt agregatni sistem. Jagode se goji v substratnih vrečah, ki so nameščene v polietilenskih ceveh, skozi katere je napeljan namakalni sistem, kjer se preko kapilarnih cevi v rastne substrate dovaja hranilna raztopina, ki vsebuje vsa hranila potrebna za rast in razvoj rastlin. Med pridelavo jagod v tleh in hidroponiki so opazne razlike v količini pridelka, njegovi kemični sestavi in senzoričnih lastnostih, ki so – odvisno od sorte, agrotehnoloških ukrepov in rastnih razmer, lahko v prid enemu ali drugemu načinu pridelave. Ekonomsko učinkovitost pridelave določa tudi potrošnik, ki se za pridelek odloča glede na videz in senzorične lastnosti. Hydroponics is a technology for growing plants in a nutrient solution, which has become increasingly popular in recent years due to the advantages it can bring, such as lower production costs, lower water consumption and a higher content of bioactive substances in the fruits. In addition to vegetables and decorative plants, hydroponics is also interesting for some worldwide present fruit species, such as the garden strawberry. Several different hydroponic techniques are known, but in strawberry production the most common technique is cultivation on rock wool (rockwool culture) and other organic and inorganic growing media, which is a closed aggregate system. Strawberries are grown in substrate bags, which are placed in polyethylene tubes, through which an irrigation system is installed and a nutrient solution containing all the nutrients necessary for plant growth and development is supplied to the growing media via capillary tubes. Between the cultivation of strawberries in soil and hydroponics, there are noticeable differences in the amount of the crop, its chemical composition and sensory properties, which - depending on the variety, agrotechnological measures and growing conditions - can be in favor of one or the other method of cultivation. The economic efficiency of production is also determined by the consumer, who chooses the product based on its appearance and sensory properties. žlahtni jagodnjak jagoda hidroponika talno gojenje pridelek kvaliteta garden strawberry strawberry hydroponics soil cultivation yield quality true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2024-09-15 07:18:07 2024-09-15 07:18:10 2024-09-18 03:21:58 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 245387 207620611 41851.pdf 41851.pdf 1 3C3760FB65B2DA3F8E2DFBE38EC59C8E 58e4cd1d717ad141658b137857c783a4f72541f4a51ebc215a8df6e15a62b2c1 d0afc331-7321-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=190839 Biotehniška fakulteta 0 0 0
