What are the cultivation methods of hydroponic tulips? Is there anything to look out for?

Tulips prefer sunny climates, warm and humid winters, and cool and dry summers, and avoid scorching heat and dampness. It is advisable to loose, fertile, slightly acidic, well-drained sandy loam soil, and avoid alkaline soil and continuous cropping. It has the characteristics of dormancy in summer, planting in autumn, and growing in soil in winter.

The suitable temperature for growth and flowering is 15 -20, the storage temperature of bulbs in summer is 20 -25, and the low temperature can be tolerated in winter.

Tulips are mainly propagated by split balls. In June, the dormant bulbs are dug up, dried and stored in a cool, dry place for planting. The planting site should choose a place with deep soil, leeward and sunny and high dryness.

After deep ploughing, a mixed base fertilizer (humus, cake fertilizer and bone meal) was applied. Put a layer of soil on top and then plant again. The depth of covering soil is generally 10 cm -15 cm, watered once after planting, and then watered again before winter.

Water once 10-15 days after the germination of young leaves in the following spring to keep the soil moist. Before leaf development and at the beginning of budding, apply 1 time of decomposed thin cake fertilizer water or compound chemical fertilizer. Flowering goes to the foliar surface to spray potassium dihydrogen phosphate 1 time.

After flowering, except for the mother plant with reserved seeds, the rest of the flower stems need to be cut in time so that the nutrients can be concentrated for the development of new bulbs. At this time, the frequency of watering should be gradually reduced to allow the new bulb to expand and enrich the texture.

1 bulb selection: hydroponic tulips need to be cold treated for bulbs, the method is: control the temperature 9 before the end of October, gradually decrease, keep the temperature from December to January at about 2, and the humidity is 85-95%.

Tulip bulbs need to be tightly wrapped in scales, undamaged, and harvested late. Otherwise, it will cause the plant beads to become shorter, the weight will be reduced, the root system will be yellow, the flowers will not bloom, and the seed bulbs will crack.

2. Planting method: When planting, press the tulip bulbs down to make them pierce the needle of the hydroponic planting tray, in order to protect the central flower bud from damage, the part of the needle into the bulb should be the surrounding part of the bulb. Bulbs with symptoms of infection should be removed, and water should be added to the planting tray immediately after planting.

3 nutrient liquid: the planting tray is placed in the rooting room with a temperature of 5 and a small amount of air flow, and it is necessary to replenish water in a timely manner, and the tap water or rainwater with a conductivity value can be used for the varieties that are prone to leaf cracking, and the water with a conductivity value of 2ms cm should be used in the rooting stage.

4. Maintenance: When the tulip root grows to 4cm, place the planting tray on the flat ground in the greenhouse to remove the susceptible or non-germinated bulbs. At this stage, it is necessary to ensure that the water level reaches the overflow outlet, the temperature is maintained at 16-18, and the humidity is maintained at 60-80%.

The number of watering at the end of the planting period can be reduced to half of the previous amount, and the tulips can be extended by providing enough water to the plants before harvesting.

Hydroponic tulips cultivation methods and precautions:

Rooting nutrient liquid must be used during hydroponics: after planting and adding water, the planting tray is placed in the rooting room with a temperature of 5 °C and a small amount of air flow, and it is necessary to replenish water in a timely manner.

Choosing the right and disease-free bulbs is the key to the hydroponic production of tulip cut flowers. After the bulbs are retrieved, they must be stored in a debugged cold storage with a temperature of 5 and a humidity of 80%. Inspect and pick out bulbs with severe penicillium disease in a timely manner.

Depending on the amount of time required, choose and determine the cultivation time and planting method. For hydroponic cut flower cultivation, the bulbs should be planted in a sterilized and watertight needle tray so that the rooting temperature is stable between 8 and the humidity is between 60% and 70%.

Rooting for about two weeks, make sure the roots are more than 3 cm long, and transport the needle tray to the greenhouse. The temperature is controlled at 15 20, the humidity is 60% 70%, and the EC value in the water is increased by adding nutrient solution to facilitate the rapid growth of tulips. In the early stage of growth, in order to prevent diseases caused by filamentous bacteria, the spray can be sprayed 2 to 3 times.

The pesticides are low-toxicity and high-efficiency, chlorothalonil, tobuzin, antibacterial, etc., and the concentration is between 750 and 1000 times.

Foliar fertilizer is sprayed at the right time according to the growth situation to coordinate vegetative growth and reproductive growth. During the growth process, due to the exudates of the root system and other ring nucleus posture conditions, a layer of oil will be produced on the surface of the needle disc water, which will make the root system lack nutrients**, resulting in a brown root system. Therefore, change the water 2 to 3 times depending on the situation.

When the harvested cut flowers are sent away in time, they must be placed in a cool and ventilated place to avoid strong light, high temperature and low temperature that affect the quality of cut flowers.

The hydroponics of tulips is also carried out according to the growth habits of tulips. Since hydroponic tulips are single-use bulbs, it is even more important to choose high-quality bulbs that have been treated at low temperatures. Fill a vase or other container with water, place the bulbs in the mouth of the container so that half of the bulbs are submerged in water, and then place the hydroponic container in an environment of 7 to 10 to promote rooting, and after the root system has formed, it will take about 15 to 20 days to move it into indoor light.

Due to the rapid water consumption of hydroponic tulips in the rooting stage, the lack of water should be checked every 2 to 3 days, and the water should be replenished in time to prevent the roots from drying up due to water loss. If the bulbs are small, some nutrient solution can also be supplemented, and the same amount of calcium nitrate can be added to the nitrogen, phosphorus and potassium compound fertilizer containing grams per liter. If calcium nitrate is not available, only compound fertilizer can be used.

In the hydroponic stage, the water or half of the nutrient solution can be changed every 3 to 4 days, and if the water solution is completely renewed at one time, the roots are easy to grow slender and not robust.
