| Abstract:
We investigated the application of the nutrient film technique (NFT) culture to tulip forcing to improve water circulation and rooting in tulip hydroponics. After precooling at 15oC for 2 or 3 weeks, dry bulbs of ‘Gander’ and ‘Ben van Zanten’ tulips were chilled at 5oC for 7 or 8 weeks. After chilling treatment, bulbs were planted using the NFT system and a plug tray. Tap water, controlled at 13oC, 18oC, or 23oC, was supplied for 30 minutes every 3 hours without adding of fertilizer. Shoot growth increased with increasing water temperature. No stem topple or other growth disorders and flower abortions were observed. The number of days to flowering increased with decreasing water temperature. The cut flower quality improved at 13oC water temperature. We conclude that NFT culture could be a good choice for tulip forcing by hydroponics. | |
