What should I pay attention to when tulips bloom?

As we know, tulips are hardy and not heat-tolerant, it will go dormant on its own in the hot season, it prefers a warm, cool climate and a leeward environment, and grows better in neutral or slightly acidic soils. A mature tulip bulb contains three generations of bulbs, or three generations of bulbs. The first generation of bulbs is the large bulb, which can be directly differentiated into a complete flower organ, and can bloom in the year after planting, while the second and third generation bulbs are subballs, which are used to breed large bulbs.

Tulips love cold and are afraid of heat, so when cultivating bulbs, they must be kept at low temperatures so that the bulbs will bloom. In their native countries, there is generally plenty of cold time in winter, and tulip bulbs are able to get enough cold treatment time to bloom naturally in spring. Generally speaking, the tulip bulbs used in production have 5 treatments and 9 treatments, and the planting methods after treatment are mainly greenhouse cultivation and in-box cultivation.

Tulips are cultivated in southern China and other southern regions, and are planted during the three months from December to February due to temperature restrictions. In South China in December, the temperature may still be very high, so when cultivating tulips, be sure to plant them in a cultivation box and put them in about 5 cold storage for 2 to 3 weeks, and when the tulip bulbs have grown roots and buds are about 1 cm to 2 cm long, they can be moved out of the cold storage and planted in the shed to grow.

Due to the high temperature in southern China, it also has a very strong impact on tulips. If there is a "warm winter" weather in southern China, a large number of tulips will bloom early, and the quality of the flowers will also be greatly affected. In order to ensure that tulips can bloom on time, the daytime temperature should be kept as much as possible during the growth period 17 20 and the night temperature 10 12.

If the growth is inhibited by water control, the phenomenon of "dried flowers" will occur. If the high temperature continues, it should be moved into the cold storage, the temperature of the cold storage should be about 8 10, and it is best to move in when the flower stem is elongated, otherwise it is easy to cause poor development of flower buds. Tulip flowering control can also be regulated by plant growth hormone.

For example, soaking tulip bulbs with gibberellin to make them bloom in a greenhouse and increase the diameter of the flowers. In short, when cultivating tulips, it is necessary to pay attention to the climate and temperature to which they are adapted, as a slight inappropriateness may lead to a series of problems.

1. Suitable temperature: Tulips are afraid of high temperature environment, and it is best to control the temperature appropriately during the flowering period, and the temperature is between 15 degrees and 20 degrees, which can promote the extension of the flowering period. If the temperature is too high, the flowers will fall early.

2. Sufficient light: If you want its flowering period to be extended and the flowers to bloom more vigorously, you must let it bask in the sun more. Place it in a well-lit area to ensure that it can get enough sun.

If it is left in the shade for a long time, the flower buds will not be differentiated, the number of flowers will be reduced a lot, and the ones that have already opened will wither early.

3. Reasonable fertilizer and water: it needs more nutrients for flowering than usual, and should be treated with fertilizer before flowering, apply enough nutrients to ensure the demand for nutrients during the flowering period, and it is best to apply phosphorus and potassium fertilizer every ten days, and stop fertilizer in time when flowering. In addition, it is also necessary to pay attention to the amount of watering, reduce watering during the flowering period, and look at the dryness and wetness of the soil before each watering.

1. Sufficient light: Tulips are long-day plants, and 8 hours of light should be ensured every day when breeding. 2. Reasonable watering:

Pay attention to the amount of watering before and after the tulip flowering period. 3. Scientific fertilization: apply thin phosphorus and potassium fertilizer to tulips every other month.

4. Ventilation: When cultivating tulips, it needs to be placed in a well-ventilated place.

1. Sufficient light

Tulips like to grow in a sunny environment, you can put it on the balcony or outdoors when breeding, so that the plants can fully photosynthesize, and promote the normal opening of the flowers, if the light is insufficient, the tulip flowers will wither and wilt.

2. Reasonable watering:

When cultivating tulips, you need to pay attention to the amount of watering, and the plants should be watered frequently before flowering, so that the roots of the plants are slightly moist, but after the tulips bloom, the frequency and amount of watering should be reduced, and the tulips should be watered every 5 days or so, so that the tulip roots remain semi-dry.

3. Scientific fertilization

Tulips do not have much demand for fertilizer, and can be applied every 20 days or so to apply nitrogen-rich compound fertilizers rich in phosphorus and potassium elements to provide nutrients for plants, and do not apply too much fertilizer, otherwise tulips will be fertilized.

4. Ventilation

When growing tulips, it is necessary to place it in a well-ventilated environment to allow the plants to breathe fresh air, or to place a small electric fan next to the tulips to allow better air circulation.

Tulips are flowers that only bloom once a year, and even if they are well maintained, they will not bloom a second time.

It blooms in March to May in spring, the flowers open more beautifully, the length of the flowering period is determined by the change of temperature, generally can last 15-25 days, which is relatively long. If the temperature is relatively high, the flowering period will be very short, lasting only one week, and if the temperature is low, it can last for two months.

1. Sunlight: It is a long-day plant, which has a certain demand for light and likes to shine in the sun, so as to ensure the normal opening of flowers, but in the first few days of flowering, it can be properly shaded to prolong the flowering period.

2. Water: Before flowering, you need to supply enough water, so as to ensure the normal growth of the plant, after flowering, you can not apply too much, as long as it is not dry.

3. Fertilizer: Its demand for fertilizer is not very large, and some fertilizer can be applied before flowering to ensure growth, so as to prepare for the arrival of the flowering period and ensure the growth of flowers.

Tulips bloom in March and May of each year, and if they are left in June and July for a week at a temperature of 34, then refrigerated, they are sown in September of that year and can bloom in December. During the differentiation of tulip flower buds, the ambient temperature should be controlled between 17 and 23, and when the light is too strong, a shade net should be built above the bulbs to weaken the intensity of the light.

Tulips generally bloom in March and May each year, but the flowering period can be changed by adjusting the temperature, if it is placed in June and July to 34 for a week, and then stored in the environment of 17 for 2 months, it can promote flower bud differentiation, sow seeds in September, and bloom in December.

During the differentiation period of tulip flower buds, the ambient temperature needs to be controlled between 17 and 23, and the temperature above 35 will inhibit the flower buds from differentiating, resulting in the inability of tulips to bloom normally. Low temperatures can also prevent tulips from flowering properly, so they need to be moved to a warm room for maintenance.

Tulips have a higher demand for light during the differentiation of flower buds, and strong light exposure will inhibit the differentiation and growth of flower buds, so it is necessary to build a shade net above to weaken the intensity of light. And when planting, the bulbs can be buried deeper, so that the tulips can bloom better.

The amount of watering is strictly controlled during the flowering period of the tulip, during which the water demand is less, and too much watering will inhibit the respiration of the roots, causing the tulip root system to rot. Therefore, it is necessary to wait until the pot is dry and white, and then properly watered and moisturized, so that the pot soil is in a slightly moist state.
