Cultivation and Management of 5 ℃ Tulip Ball
5 ℃ tulip balls need enough time to complete each stage of development, and the treatment time required by each variety is also different, so each variety has an earliest and latest planting time, during which growers can choose the most suitable planting time according to the actual situation and their own expectations of the market. The preparation before planting should be planted immediately after receiving the seed ball. If the soil temperature is higher than 16 ℃, it can be stored for up to 1-2 weeks. Store the bulb at a temperature of 2 ℃ ~ 5 ℃, relative humidity of 70% and

Cultivation requirements of 5 ℃ Tulip bulb
1. Carefully remove the brown outer epidermis from the roots before planting. two。 On slightly moist soil, plant bulbs at the specified number of bulbs per square meter and at the correct depth. 3. Provide recommended temperature conditions for bulb depth and plant height in the greenhouse. 4. The relative humidity in the greenhouse must not exceed 80%. 5. To maintain the optimal water content of the soil in the greenhouse. 6. Check plants, temperature, and relative humidity frequently; be sure to use annual testing equipment. Removal of the bulb

Cultivation techniques of 5 °C Tulip
How much water should be watered? After planting, the bulbs must be provided with enough water so that they can take root well. If the bulb is planted shallowly, water should be watered several times after planting. In the process of crop growth, excessive water supply should also be avoided. The frequency of watering depends on the following factors: the growth stage of the crop, climatic conditions, ventilation, the characteristics of the varieties cultivated, the type of soil and the depth of planting. In other words, it is difficult to give an exact figure of how much water should be watered.

Production of cut tulip flowers and prevention of blind flowers
Tulip (TulipagesnerianaL.), also known as lotus and musk grass, is a perennial bulb ornamental flower of Liliaceae. It is one of the famous flower varieties in the world, known as "king of flowers" [1Jing 2jue 3]. In China, the production technology of box cut tulip flowers, the causes of blind flower formation and prevention techniques are still relatively backward, which restricts the development of tulip cut flower production. The flower base of Hebei Academy of Forestry Sciences has made great efforts to develop soilless cultivation of tulips.

Canker of cut tulip flowers
It is mainly spread by bulbs, infecting new buds in the process of tulip germination, causing disease in the aboveground part. The suitable temperature for infection was 10 ℃ ~ 15 ℃, which was consistent with the growth temperature of tulip in the early stage. The disease occurs more frequently during the period from bulb germination to the expansion of the first leaf, which can last until flowering. At the initial stage of the disease, the disease spot on the leaf was waterlogged or gray-white disease spot, and in severe cases, the epidermis was detached from the mesophyll, resulting in cracking to expose the mesophyll, and yellow disease spots were formed on the bulb. Control methods: diseased plants are removed and destroyed in time, and agricultural streptomycin is sprinkled in the surrounding soil.

What about the degradation of tulip varieties?
Prevention and control methods: 1. When planting, use stem tip to culture virus-free seedlings, or select varieties with strong resistance to virus; 2. In time

Causes of blind branches and blind flowers of tulips
Tulip belongs to Liliaceae, Tulip belongs to perennial bulb herb. It has tall and straight plants, large and gorgeous flowers, and high ornamental value. However, if the nursing is not proper, tulips are prone to blind branches and blind flowers. The symptoms of blind flowers are that the branches and leaves develop normally, the weak ones lose water, the flower buds are white, the leaves are pointed, and the flower stems are atrophied; in the strong ones, the flower stems are short, the petals remain green or white, and curl with stamens and pistils, which can not open completely. Blind branch, that is, the aboveground part of the plant has only one hypertrophic leaf and no leafy branches.

Fusarium wilt of Tulip
The disease is also known as tulip base rot. It is a fungal disease, which is specialized by Fusarium moniliforme and Fusarium oxysporum. It is host-specific and only harms tulips. All of them are caused by semi-known fungi. The pathogen overwintered with mycelia and chlamydospores in infected bulbs and soil. Under the condition of suitable temperature (20 ℃ ~ 34 ℃) and high humidity, a large number of spores were produced and spread by Rain Water sputtering. Excessive application of nitrogen fertilizer can aggravate the damage, and the application of compost with diseased remains not fully mature can also increase the chance of disease. The transportation of seed bulbs is helpful to the long-distance spread of the disease. Plant a diseased bulb

Tulips blossom for three years in a row
Since 1998, I have been planted with 8 tulip bulbs sold in the market for three consecutive years, blooming every year, and have bred 40 or 50 bulbs. The book says that tulips are planted at the end of October and early November, and the main producing country, the Netherlands, is a high-latitude country with a cold climate, so tulips should grow in a cold environment, and potted plants should be kept outside, not indoors or in a greenhouse. Otherwise, it will not blossom (this is also the conclusion I reached in a comparative experiment). It does not sprout outdoors in winter until early spring and February.

Tulip bud management
1, temperature when the leaves grow 4~5 pieces, the middle of a young flower stem, the temperature can be increased to 22~24 C, 8 am, 13~15℃; 2 pm 22~24℃; 5 pm, 16~18℃. 2. Water should not be poured on the buds to prevent them from rotting. The humidity of the air is maintained at more than 70%, so not only should water be sprayed frequently on the plants and flowerpots, but also around the flowerpots and all open spaces in the field should be sprayed frequently. A water container is placed in the planting field to continuously supply air.
