Choosing the right bulb size tulip plant requires high quality bulbs. This is because even if only one bulb in the pot does not germinate, it will affect the whole pot cultivation effect and make it a defective product.
Planning from bulb processing to flowering stage After the bulbs are harvested, the bulbs of the tulip need to be subjected to a high temperature treatment followed by a low temperature treatment to allow them to bloom in early spring. Whether it is the production of tulip flowers or cut flowers, flowering in advance, these requirements must be met. It can be done by temperature treatment. In the heat treatment stage after the bulb is harvested, it is the time when the leaves, peduncles and flowers (in the above order) are formed in the bulb. Once the pistil is formed, the flower is formed, which means that the G phase is reached. After the G stage is reached, after a short intermediate temperature treatment, the bulbs that are expected to bloom early can be treated cold. For late-flowering bulbs, the heat treatment stage must be extended to delay the onset of cold treatment.
Second, control growth through proper cold treatment. Pay attention to temperature For wild type or other dwarf varieties, the preparation of potted flower production is actually the same as cut flower production. But be careful not to make the cold treatment time of the bulb too long, which will make them grow too high. For the treatment of early flowering bulbs, it is best to dry the ball for a certain period of time, and then prepare the ball to the greenhouse for two months before the cold treatment.
Unripe bulbs can be directly on the pot to complete all their cold treatment. Excessive root systems can even be controlled at low temperatures after rooting. When early cultivation is promoted, the lack of cold treatment sometimes leads to blind flowers.
For tulips that require flowering on Christmas, use special varieties and special treatment.
The treatment of the ball after arrival is recommended to use the already processed bulb. This eliminates the need for storage and the danger of storage.
When arrival, the bulbs cannot be planted or processed yet, and they need to be stored in a dry, cool and moderately ventilated building. The best method is to use a bulb that has been partially cooled and stored at a low temperature of 5°C or 9°C. Uncooled bulbs are stored at 17°C, and the environment requires drying and good air circulation until the bulbs are planted or placed in a freezer and required for completion at 9°C, 5°C, or 2°C Cold treatment.
