Hyacinth is beautiful. Who opens it and who is happy?

Hyacinth is a perennial herbaceous bulbous plant with an ovate bulb with a membranous bark and a positive correlation between the color of the skin and the color of the flower. It is shaped like garlic before flowering and is native to the Mediterranean coast and Asia minor. It is one of the most fragrant flowering plants found in the study. Like the sunny and humid growth environment, require good drainage and fertile sandy loam and so on.

Morphological characteristics: hyacinth is a perennial herbaceous bulb plant, bulb spherical or oblate, with membranous outer skin, outer coat is purplish blue or white, etc., the color of skin membrane is positively correlated with flower color. It looks like garlic before it blossoms.

Leaves 4-9, narrowly lanceolate, fleshy, basal, hypertrophic, banded-lanceolate, with shallow longitudinal furrows, green and glossy. Flowering stems fleshy, scape 15-45 cm tall, hollow, terminal bearing racemes; florets 10-20 densely growing distally, rarely pendulous, funnelform, perianth tube-shaped, distally quadrifid, Corolla funnelform, basal floral tube longer, lobes 5.

Roll backwards and downwards. According to its color, it can be roughly divided into eight strains: blue, pink, white, goose yellow, purple, yellow, scarlet, red and so on. The original species is light purple and fragrant. Capsule.

The florescence is in early spring and the natural florescence is from March to April.

Ecological habits: 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.

It took root in autumn, unearthed new buds in early spring, bloomed in March, ripened in late May, withered in the ground in early June and went into dormancy.

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.

Mode of reproduction

Divide the ball: after digging up the bulb in June, separate the big ball from the sub-ball. "the big ball can blossom in early spring next year after autumn planting, and the seed ball needs to be cultivated for 3 years before it can blossom." Due to the low natural ball division rate of hyacinth, the mother plant can only divide 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 the summer dormant period.

Sowing: it is often used when 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. Bulbs cultured from seedlings blossom after 4-5 years. Under general conditions, the germination ability of seeds can be maintained for 3 years.

Soil: hyacinth should choose sandy loam with good drainage and not too dry, which requires fertile soil, high content of organic matter, good aggregate structure, neutral to slightly alkaline, pH 6-7. The culture soil can be prepared according to the ratio of rotten leaf soil 5 ∶ garden soil 3 ∶ coarse sand 1.5 ∶ bone powder 0.5. Before planting, chemical agents such as formalin can be used to cover the soil surface immediately after applying formalin at a soil temperature of 10-15 ℃. After 3 days of warm weather, remove the film and plant it after 1 day to keep the soil moist. Before planting, we should apply enough base fertilizer, cultivate in the field, and avoid continuous cropping.

It is suitable to be carried out from October to November, and the selection of soil with good drainage is the most important condition. Apply enough base fertilizer before planting, add a thin layer of sand, and then line up the bulbs, 15 cm-18 cm apart and 5 cm-8 cm covered with soil. And cover with grass to keep the soil loose and moist. Generally, there is no other management before flowering. If seeds are not to be collected after flowering, the flower stem should be cut off to promote bulb development. The cutting position should be in the uppermost part of the flower stem as far as possible. The bulb roots can be dug up in early June, spread out and stored in cold storage, and the summer temperature should not exceed 28 ℃.

Potted with loam, rotten leaf soil, fine sand and other mixed nutrient soil, generally 10 cm caliber potted one ball, 15 cm caliber potted 2-3 balls, and then buried in the pot, the overlying soil 10 cm-15 cm, after 7-8 weeks, buds grow to more than 10 cm, go to cover the soil to make the sun shine, generally planted in October-November, flowering in March.

Hyacinth aquaculture requires that the water level should have a space of 1-2cm from the chassis of the bulb, so that the root system can breathe, and it is strictly forbidden to add water to the bottom of the bulb.

In December, you can put the seed ball in a wide-mouthed glass bottle and add a little charcoal to help with antisepsis and disinfection.

The seed ball is only dipped to the bottom of the ball, then it is placed in a dark place and the bottle is covered with black cloth, so that after germinating in an all-black environment for more than 20 days, it is put outdoors to be exposed to sunlight for 1-2 hours a day at first, and then gradually increased to 7-8 hours, most of which can blossom during the Spring Festival when the weather is good.
