How are tulips treated at low temperatures?

Tulips can be treated at low temperatures in the refrigerator compartment or refrigerated in cold storage if large quantities are processed at low temperatures. Freezer treatment can allow them to germinate. After packing it in a convenient bag or paper, put it in the refrigerator compartment and set the desired temperature.

Low temperature treatment: 3 degrees, 5 degrees, and 9 degrees (room temperature), after a month of low temperature treatment, after planting 3 degrees of ball flowering for a month, 5 degrees of ball flowering for a month and a half, 9 degrees of room temperature ball that is naturally cooled in winter, generally planted in March, May Day.

Flowering, urban beautification placement, the amount is very large.

Low temperature treatment of bulbs:

In order to precede the flowering period of the bulbs, in October and November, after 2 months of low temperature treatment at 5 9, the bulbs were sown in the greenhouse for furrow cultivation or potted plants. Ground planting density 11 cm 12 cm, surface cover 3 5 cm, under 5 15 conditions, planted in December, flowering in 2 March, can be made fresh cut flowers or potted flowers**. Potted plants with 15 18 cm pots, 3 4 balls per pot, shallow soil, so that the tip of the ball is exposed on the surface of the potting soil, watered thoroughly and moisturized, keep 5 15 times, 1 2 months of flowering.

For bulbs that have not been artificially treated at low temperatures, they must be planted in the open field in winter, and natural cold treatment can make flowering, but the flowering period is extended to April and May. The effect of low temperature here may be the conditions required to promote the physiological ripening of flower buds.

Tulip low temperature treatment, only need to wrap its bulbs in newspaper, and then put it in the refrigerator refrigerated layer, and control the temperature at about 5, so that the refrigeration can be about a month, and then it can be planted in the soil, pay attention to the maintenance, you need to let it have enough water and nutrients.

1. Handling method

The low temperature treatment of tulips is very simple, first clean its seed bulbs, then dry the skin, then wrap it in newspaper, and then put it in the refrigerator, the temperature is about 5 is more suitable, so that after a month of refrigeration, you can plant, and the tulips after low temperature treatment can soon bloom.

2. Plant

After the low temperature treatment, the tulips can be planted, using loose, fertile and well-drained soil as a cultivation medium, and then planting the bulbs deep into the soil, and then shading them moderately, so that the light does not inhibit the elongation of the flower buds, so that it can grow vigorously soon.

3. Sufficient moisture

After the tulip bulb is planted, it also needs to be watered sufficiently, at this time we need to water frequently, and it is most appropriate to keep the soil slightly moist, but it is necessary to pay attention not to let the soil have stagnant water, otherwise it will have rotten roots, so when watering, it is best to master the principle of a small amount of many times.

4. Sufficient nutrients

If you want tulips to grow vigorously, then during its growth period, you need to apply a thin rotting fertilizer water every 10 days or so to meet its growth needs, pay attention to its flowering period should not be fertilized, it is also necessary to apply fertilizer once after flowering, in order to promote the growth and development of its bulbs.

Tulips in different periods of temperature needs are different, in the summer breeding, the temperature should be controlled at about 20, in the winter when it is in the rooting period, this time the temperature needs to be around 10, and in the growth period, the temperature control should be between 15-20 optimal.

1. Temperature requirements

Tulips in different periods of temperature requirements are different, it is not heat-tolerant plants, so in the summer to save its bulbs, it is best to control the temperature at about 20 at this time, which is conducive to the development of its bulbs, but also to promote the differentiation of its flower buds, otherwise the temperature is too high it is easy to develop deformities.

2. Winter temperature

Tulips have the habit of taking root and germinating new shoots in autumn and winter but not unearthed, it has a strong cold tolerance, at this time its bulbs can tolerate a low temperature environment of -14, and the most suitable growth temperature of its root system is above 5 and below 14, so it is best to control the temperature at about 10.

3. Growth temperature

Tulips in the growth period, like to grow in a cool climate, every spring is its growth and flowering period, at this time we had better put the temperature about 15-20, otherwise the temperature is too low, its growth will become slow, the temperature is too high it is easy to wilt and die.

4. Precautions

When maintaining tulips, in addition to the need for chain wool to make it have a suitable temperature, but also need to do a good job in other aspects of maintenance management, it likes moisture, so the maintenance process should be watered frequently, but it is necessary to pay attention not to let the soil produce water, in its growth period also need to apply thin fertilizer for it, but also to let it have sufficient light.

1. Soil: To choose a suitable pot and soil for planting, the pot can be made of mud pots to be more breathable, and the soil should also be soft and breathable soil, which can be mixed with peat soil and some river sand, with a ratio of 2:1 is the best, so that the soil is not only permeable, but also nutritious.

When planting the bulbs, gently press the surrounding soil.

2. Environment: When the tulip is just bought, it needs to be adapted to the home environment, disinfected and planted. It needs to be left in a place with mild sunlight for a while to allow it to acclimatize for a while.

Water less, do not fertilize, be sure to wait until it begins to grow again, and then carry out daily regular maintenance.

3. Watering: When adapting to the environment, you don't need to water too much, on average, 4 to 6 days of cracked oak watering once, keep the soil slightly moist. Wait until the leaves start to stretch, and then carry out normal watering, that is, dry and watering.

4. Fertilization: When planting to pots, there is no need to fertilize. When some leaves have grown, it is time to apply fertilizer.

Do not apply a large amount of fertilizer at one time, it is easy to burn out its roots. Use some manure cake or rotten fertilizer and refertilize after the flower buds appear.

If you want to let the tulips overwinter, you need to take good temperature control measures, and it is best to control the temperature at about 10, which is conducive to the growth of its root system. It is also necessary to water reasonably, and observe the dryness and humidity of the soil before each watering, and it is most appropriate to keep the soil slightly moist. At this time, it is necessary to stop fertilizing to avoid fertilizer damage.

1. Temperature control measures

If you want to let the tulip overwinter, you need to do a good job of temperature control measures, although it is a hardy plant, it is the temperature of about 10 is the most conducive to its root growth, so we had better control the temperature at about 10 yards, and when the temperature rises in the next spring, it can grow vigorously.

2. Reasonable watering

If you want tulips to overwinter, you also need to water them reasonably, it likes to grow in a humid environment, but the water evaporates slowly in winter, if the soil has stagnant water, it is prone to root rot, so at this time it is necessary to water late according to the dryness and humidity of the soil, and it is most appropriate to keep the soil slightly moist.

3. Stop fertilizing

The growth of tulips in winter is relatively slow, at this time its demand for fertilizer is not high, so to stop fertilization, do not apply any fertilizer, otherwise it is easy to cause fertilizer damage, generally in autumn in the soil to apply enough base fertilizer, and wait until the next spring it begins to germinate before fertilization.

There is a "three basis point" of temperature, that is, the lowest temperature, the optimal temperature and the maximum temperature, that is, the lowest point, the most suitable point and the highest point of the temperature.

Tulips take a long time from the formation of bulbs to flowering, and several processes go through that require certain temperatures. Tulips are more hardy, and the underground part of the bulb can tolerate temperatures of up to 35 in winter. The rooting temperature should be higher than 5, and the growth temperature of the root should be below 14, especially about 10 is the most suitable.

The suitable growth temperature during the growth period was 5 20 , and the optimal suitable temperature was 15 18. The suitable temperature for flower bud differentiation was 17 23, and the flower bud differentiation was inhibited when it was higher than 35.

Tulip flower bud differentiation is characterized by completion in the bulb, so the temperature in June and July after flowering and the temperature of bulb storage are very important, if it is in high temperature in June (20 25 or above) and falls in July (below 20), the flower bud differentiation is smooth; If the bulb is stored at a high temperature of more than 35 °C, the flower buds will be deformed, or the tepals will be partially leafed.

Tulip hardy -14 .

If the temperature is below -14, the tulips will suffer frostbite. Tulips are best placed indoors in winter, keeping the room temperature above 15 and reducing watering to avoid stagnant water. At the same time, it is necessary to supplement it with scattered light in time, apply thin fertilizer before winter, promote the growth of tulips, and accumulate nutrients for the next year's flowering.

Tulips need to be placed indoors to survive the winter, although tulips have good cold tolerance, but when the outdoor temperature is too low, it will cause tulips to grow slowly. Therefore, tulips should be warmed and maintained indoors in winter, and the temperature should be controlled above 15.

Tulips in winter should pay attention to control the amount of watering, so as not to overwatering the soil water, it is best to water after the surface of the soil is dry, and the appropriate amount of watering can keep the soil relatively moist. The water temperature should not be too low, and it is best to be close to room temperature.

Tulip flower language Hu Void Pure:

Tulip flower language refers to the different meanings of each color of tulips.
