The breeding method of the latest hyacinth

Hyacinths are usually propagated mainly by dividing balls, which can be propagated by seeds or bulbs in breeding. After one year of planting, the mother balls can be divided into 1 or 2 bulbs, and some varieties can be divided into ten or more bulbs. It can be used for bulb reproduction, which takes 3 years to blossom. The seeds propagate, sow in autumn, germinate in February of the following year, and the seedlings blossom after 4 or 5 years of culture. let's take a look at the breeding methods of hyacinth.

Growth habits of hyacinth

Hyacinth habits like the sun, cold-resistant, suitable for growing in a cool and humid environment and loose, fertile sandy soil, avoid stagnant water. Like warm and humid winter, cool summer slightly dry, sunny or semi-overcast environment. Like fertilizer, suitable for fertile, well-drained sandy loam. It can be planted in the ground, potted or raised in water.

Hyacinth takes root in autumn, new buds are unearthed in early spring, blossom in March, fruit is ripe in late May, and the aboveground part withered and went into dormancy in early June. The flower bud differentiation was carried out in the dormant period, the optimum temperature for differentiation was about 25 ℃, and the differentiation process was about 1 month. There should be a low temperature stage of about two months after flower bud differentiation to before elongation and growth, and the temperature should not exceed 13 ℃.

During the growth of hyacinth, the root growth of bulb was the best when the temperature was 2-6 ℃. The optimum temperature for bud germination is 5-10 ℃, the optimum temperature for leaf growth is 5-12 ℃, and the most favorable temperature for budding and flowering is 15-18 ℃. The storage temperature of bulb is 20-28 ℃, and the optimum storage temperature is 25 ℃, which is the most ideal for flower bud differentiation. Can withstand short-term frost. Like cool, moist air, sunny environment, more cold-resistant.

Split-ball propagation of hyacinth

After digging up the bulb in June, separate the bulb from the bulb. "the bulb can blossom in early spring next year after autumn planting, and the bulb needs to be cultivated for 3 years before it can blossom. Due to the low natural bulbbing rate of hyacinth, the mother plant can only produce 1-2 bulbs after planting for one year. In order to improve the reproduction coefficient, castration can be used to stimulate the bulbs to grow in summer dormancy.

The method is that in August, when the flower bud has been formed, the stem disk at the bottom of the bulb is evenly dug off, so that the wound at the stem disk is concave, and then cut vertically and horizontally from the bottom to the top, showing a cross incision, reaching the center of the bud in the bulb. At this time, there will be mucus outflow, apply 0.1% mercury solution to smear and disinfect, then expose it in the hot sun for 1 hour, and then spread it indoors. Keep it at room temperature for about 21 ℃. Make it produce callus, when the base of the scale expands, the temperature gradually rises to 30 ℃, the relative humidity is 85%, many small bulbs are formed in about three months, and the bulblets are induced to bloom for 3 ~ 4 years.

Seed propagation of hyacinth

Hyacinth seed propagation is mostly used in cultivating new varieties. It is sowed into the culture soil in the cold bed in autumn, covered with soil of 1 cm, and germinated at the end of January and the beginning of February of the following year. The bulbs cultured from seedlings blossomed after 4-5 years, and the germination ability of seeds could be maintained for 3 years under general storage conditions.
