The flower shape of this plant is very beautiful after such a twists and turns, whether it is soil culture or hydroponic culture.

Hyacinth is prone to yellow rot when it is hot and humid. At the onset of the disease, the leaf tip begins to expand into spots, then becomes brown and necrotic, the bulb heart decays, and the mucus turns yellow. Disease-free ball was selected for prevention and control, and 1000-fold solution of agricultural streptomycin was sprayed regularly.

Hyacinth habits like the sun, cold-resistant, suitable for growing in a cool and humid environment, soil loose, fertile, to avoid stagnant water. Warm and humid in winter, cool and dry in summer, sunny or semi-cloudy. Like fertilization, should be fertile, well-drained sandy loam. Planting, potted plants and watering are all available.

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

The steps of hydroponic hyacinth culture are as follows:

1, glass bottle cleaning, pour tap water, can not fill the water hyacinth lamp chassis 1-3 cm distance limit.

2. Change the water for hyacinth once a week (in order to ensure that the water in the bottle is clean). Do not use nutrient solution. Generally, tap water is enough to supply hyacinth growth.

3. Don't make any light in front of the green leaves. You can put it in a small dark corner. With the development of white root, we can bask in the sun. At the beginning of 1-2 hours, gradually increase the light time. If the weather is warm, it will start soon.

Hyacinth likes the sunny, warm, moist and cool summer environment, hardy, fertilizing, fertile and loose sandy soil to avoid heavy soil and wet stains. Hyacinth is planted in pots.

Hyacinth should be well drained, sandy loam soil should not be too dry, soil fertility is high, organic matter content is high, aggregate structure is good, neutral to slightly alkaline, ph 6-7 level, culture soil can be prepared according to the proportion of humus soil 5%, garden soil 3%, coarse sand 1.5%, bone powder 0.5%. Chemical agents such as formalin can be used before planting. When the soil temperature is 10-15 ℃, cover the soil surface immediately after application, uncover the film in warm weather for 3 days, plant in air for 1 day, and keep the soil moist. Before planting, it is necessary to apply sufficient base fertilizer and cultivate in the field to avoid continuous cropping.
