This method of using water to prepare plants without using any soil is now very popular among office workers. Hyacinth bulbs can be planted through hydroponics, so how to do it? Let's take a look at the diagram of hyacinth bulb hydroponics operation. [Warning] The whole plant of hyacinth is poisonous Illustration of the operation of hydroponics of hyacinth bulbs Hyacinthus is a perennial herbaceous bulbous plant with a spherical or oblate bulb with a membranous outer skin. The outer membrane is purple-blue or white, and the color of the membrane is positively correlated with the color of the flower. It is generally planted with bulbs. Today, let's learn how to plant hyacinth bulbs.

To plant hyacinth bulbs, dig up the bulbs in June and separate the large bulbs from the small bulbs. "The large bulbs planted in autumn can bloom in the early spring of the following year, while the small bulbs need to be cultivated for three years before they can bloom. Since the natural bulb division rate of hyacinth is low, generally the mother plant can only produce 1-2 small bulbs after one year of planting. In order to increase the reproduction coefficient, castration surgery can be performed on the large bulbs during the summer dormancy period to stimulate it to grow small bulbs.

Before planting hyacinth bulbs, apply enough basal fertilizer, add a thin layer of sand on top, and then arrange the bulbs with a spacing of 15 cm to 18 cm, and cover with 5 cm to 8 cm of soil. Cover with grass to keep the soil loose and moist. Generally, no other management is done before flowering. If you do not plan to collect seeds after flowering, you should cut off the flower stems to promote the development of bulbs. The cutting position should be as high as possible at the top of the flower stems. The bulbs can be dug out in early June, spread out, graded and stored in a cold storage. The temperature in summer should not exceed 28℃.

After planting, hyacinth bulbs can be cultivated in a greenhouse to make them bloom at the end of the year. Because the sensitivity of cultivated varieties to forcing varies greatly, varieties suitable for forcing should be selected when forcing. Hyacinth only needs more than 5000Lx to maintain normal physiological activities. Too weak light will cause the plant to be weak, the stem to be too long, the flower bud to be small, the flowers to wither early, the leaves to turn yellow, etc. You can use incandescent lamps at a distance of about 1 meter to provide supplementary light, but too strong light will also cause burns to the leaves and petals or shorten the flowering period.

Hyacinth bulb care Compared to other bulbous plants, hyacinths are subjected to special temperature treatments to accelerate flower formation. One way to achieve this is to increase the soil temperature during the bulb growth period. This method is rarely used due to its high cost. More commonly, the bulbs are dug early and temperature treated in an air-conditioned room to promote flower formation. The time of digging and the temperature of the treatment are the factors that distinguish potted and cut hyacinths.

The growth process of hyacinth includes a leaf formation period, a flower formation period and an elongation period. By advancing the flower formation period and providing the most effective low temperature period, the flowering of the bulbs can be promoted. This is why hyacinths planted in the Mediterranean region often bloom very early. By maintaining a higher temperature during the bulb planting stage, the leaf formation period can be accelerated, so the flower formation period is also advanced. |
