Matters needing attention of hydroponic tulips

1. In the soaking stage, we should pay attention to putting the flower seeds straight, preferably perpendicular to the bottom of the hydroponic pot.

2. In the process of changing tulip seeds, one should be extra careful and handle it gently.

What are the cultivation methods and matters needing attention of hydroponic tulips?

Hydroponic tulips are ornamental plants that are the main export of the Netherlands. They also belong to one of the economic lifelines of the Netherlands. Together with windmills, they are called one of the symbols of the Netherlands. So what are the cultivation methods and matters needing attention of hydroponic tulips? Let's get to know it with the editor.

* basic introduction Tulip is originally intended to be a flower, but in plant taxonomy it is a kind of bulbous herb belonging to the genus Tulip of Liliaceae, and it is also the national flower of the Netherlands. Tulips were first hydroponically cultivated by larger growers in Denmark and southern Sweden in the 1970s.

* the culture method of hydroponic tulips the time of cold treatment of bulbs in hydroponic culture is longer than that in substrate cultivation. As a result of this long-term storage, it is easy to be infected with Penicillium and Mucor, so you only need to wrap it tightly with scales. it is not damaged and the seed ball is received relatively late. otherwise, it may cause the yellowing plant of its root system to become shorter, the weight reduced, the flowering and the seed ball cracking, and so on.

When planting, the bulbs should be pressed down so that they can be stuck on the needle of the hydroponic planting plate. In order to protect the central flower bud from damage, the seed balls with symptoms of infection should be removed during planting. After planting, water should be added to the planting plate. After planting and adding water, put the planting plate in a rooting chamber with a temperature of 5 °C and a small amount of air flow, and timely replenish water. Tap water with electrical conductivity of 1.5ms/cm can be used when watering, and Rain Water can also be used. For varieties prone to leaf cracking, water with electrical conductivity of 2ms/cm should be used in the rooting stage.

* what are the precautions for hydroponic tulips? When its roots grow to 4cm, its rooting stage can be over, and then use the planting tray on a relatively flat ground in the greenhouse, check for susceptible or ungerminated bulbs, and remove them to prevent the spread of germs. At this stage, make sure that the water level reaches the overflow outlet to ensure the water supply, at which time the temperature is maintained at 16-18 °C and the relative temperature is maintained at 60-80%. The frequency of watering at the end of planting can be reduced to half of that before harvest, and enough water should be provided to the plant before harvest to prolong the flowering period.

Matters needing attention in hydroponic production of cut tulip flowers

Tulip is a very popular flower variety, and now there are often flower friends who cultivate tulips in water. Tulips can not only be potted, but also often used for cut flowers, so professional breeders will produce cut tulips in water, so what problems should be paid attention to in hydroponic production of cut tulips?

Tulips (details)

1. Selecting suitable and disease-free bulbs is the key to hydroponic production of cut tulip flowers.

2. After the seed balls are shipped back, they must be stored in a cold storage that has been debugged. The temperature is 5 ℃ and the humidity is less than 80%. Check and select the seeds with serious penicilliosis in time.

3. According to the time needed, select and determine the cultivation time and planting mode. For hydroponic cut flower cultivation, the bulb should be planted in a sterilized and watertight needle plate so that the rooting temperature is 8 ℃ and the humidity is between 60% and 70%.

4. Take root for about two weeks, make sure the root length is more than 3 cm, and transport the needle plate to the greenhouse. The temperature is controlled from 15 ℃ to 20 ℃, the humidity is 60% to 70%, and the EC value in the water is 1.5ms to 2.0 ms by adding nutrient solution to facilitate the rapid growth of tulips.

5. In order to prevent the diseases caused by filamentous bacteria in the initial stage of growth, it can be sprayed for 2 to 3 times. The low toxicity and high efficiency chlorothalonil, topiramate and trimethoprim were selected, and the concentration was between 750 and 1000 times.

6. Spray foliar fertilizer timely according to the growth situation to coordinate vegetative growth and reproductive growth.

7. In the process of growth, due to the action of root exudates and other environmental conditions, a layer of oil film will be produced on the water surface of the needle disk, which will make the root lack of nutrient supply and cause the root system to be brown. Therefore, change the water for 2 to 3 times as appropriate.

8. when the harvested cut flowers are not sent away in time, they must be placed in a cool and ventilated place to avoid strong light, high temperature and low temperature, which will affect the quality of cut flowers.
