When the temperature of bulb is 2-6 ℃, the growth of root system is the best, the suitable temperature of bud germination is 5-10 ℃, the suitable temperature of leaf growth is 10-12 ℃, and the optimum temperature of bud flowering is 15-18 ℃. The storage temperature of bulb is 20-28 ℃, the optimum temperature is 25 ℃, which is the best for flower bud differentiation.
During the cultivation of hyacinth, it is recommended to give a proper amount of light time every day. If the light is too weak, it will cause the plant to be thin, the flower bud to be small, and the leaves to be yellow, etc., but the light intensity should not be too large. If the light is too strong, it will cause the flower period of hyacinth to be too short.
Hyacinth should choose a sandy loam with good drainage and not too dry, which requires fertile soil, high organic content, good aggregate structure, neutral to slightly alkaline, pH value of 6-7. The potted medium can be mixed with humus rich humus soil, garden soil, coarse sand and a small amount of bone meal.
The principle of watering is to see wet and dry. Note that the water content should not be too much, and the basin soil should not be too dry.
Generally, after planting and watering in the north, no water is needed for half a month; if it is in the south, no water is needed for a month. Sometimes, although the soil surface is dry, the bottom is wet, and watering is unnecessary.
The watering time for keeping the humidity of greenhouse is better in the morning.
1. Precautions for summer
① in the later stage of cultivation, the fertilizer and water should be controlled to prevent the bulb from rotting in rainy season.
② the bulbs shall not be stored in the soil in summer, and they shall be dug up and stored every year, and the bulbs shall be fully dried in the shade, or they will not bear storage.
2. Storage precautions
① harvest bulbs in time, early harvest, growth is not full, too late often in rainy season, soil is too wet.
② the storage environment must be dry and cool, and the bulbs should be spread in layers to facilitate ventilation.
3. Other precautions
Hyacinth can grow only in the low temperature environment, so we should let it grow in the natural environment, and move it into the room after the temperature is lower than 0 ℃.
