What should be noted in the hydroponic production of tulip cut flowers?
Tulips are a very popular flower variety, and now flower enthusiasts often grow tulips hydroponically. Tulips can not only be grown in pots, but are also often used as cut flower material, so professional growers carry out hydroponic production of tulip cut flowers. So what issues should be noted in the hydroponic production of tulip cut flowers?
Tulip (detailed introduction)
1. Selecting suitable and disease-free bulbs is the key to the hydroponic production of tulip cut flowers.
2. After the bulbs are transported back, they must be stored in a well-adjusted cold storage room, with a temperature of 5°C and humidity within 80%. Check in time and pick out bulbs with severe penicillium disease.
3. According to the time when flowers are needed, choose and determine the cultivation time and planting method. For hydroponic cut flower cultivation, the bulbs should be planted in disinfected and watertight pin trays, so that the rooting temperature is kept stable at 8°C and the humidity between 60% and 70%.
4. About two weeks after rooting, make sure the roots are more than 3 cm long, and move the pin trays to the greenhouse. Keep the temperature at 15°C to 20°C and the humidity at 60% to 70%, and add nutrient solution so that the Ec value in the water is 1.5 ms to 2.0 ms, to facilitate the rapid growth of tulips.
5. In the early stage of growth, to prevent diseases caused by filamentous fungi, spray 2 to 3 times. Choose low-toxicity, high-efficiency agents such as chlorothalonil, thiophanate-methyl, and thiram, with a concentration between 750 and 1000 times.
6. According to the growth situation, spray foliar fertilizer at the appropriate time to coordinate vegetative growth and reproductive growth.
7. During the growth process, due to root secretions and the effects of other environmental conditions, a layer of oil film will form on the water surface of the pin tray, which will cause the root system to lack nutrient supply and lead to the roots turning brown. Therefore, change the water 2 to 3 times as the situation requires.
8. When the harvested finished cut flowers cannot be sent away in time, they must be placed in a cool, ventilated place, avoiding strong light, high temperature, and low temperature, which would affect the quality of the cut flowers.
Hydroponic production methods for tulip cut flowers
Tulips belong to the Liliaceae family of perennial herbaceous plants, and are welcomed by people because of their large flowers and bright colors. Because they sell well on the market, various countries have devoted themselves to researching their cultivation techniques, and hydroponic cut flower production has gradually become popular among professional growers. China began introduction trials and cultivation in the 1990s. At present, the main domestic hydroponic experience is:1.
