Hyacinth is also known as Western Narcissus, Western Narcissus and five color Narcissus. It belongs to the bulbous plant of perennial herbaceous plant. Its flowers are rich in color, such as red, blue, white, yellow, purple and so on. The main way of propagation is to divide the bulbous. Flower language has joy, competition, bet, game, sorrow, sad love, eternal memory, etc.
The cultivation of hyacinth can be divided into soil culture and water culture. Let's learn the method of hyacinth soil culture and water culture.
I. selection of soil:
The suitable soil for hyacinth should be sandy loam with good drainage and not too dry. The soil should be fertile, with high organic matter content, good aggregate structure, neutral to slightly alkaline, and pH value of 6-7. The culture soil can be prepared according to the ratio of saprophytic soil 5:garden soil 3:coarse sand 1.5:bone meal 0.5. Before planting, chemicals such as formalin can be applied on the soil surface at the soil temperature of 10-15 ℃ Cover the film immediately after the medicine, remove the film after 3 days in warm weather, and plant after 1 day in the air to keep the soil moist. Before planting, sufficient base fertilizer shall be applied, and field cultivation shall be avoided.
It is suitable for October to November. The most important condition is to select the soil with good drainage. Before planting, apply enough basic fertilizer, add a thin layer of sand on it, and then arrange the bulbs, with the plant spacing of 15cm-18cm and the soil covering of 5cm-8cm. And cover with grass to keep the soil loose and moist. Generally, no other management shall be conducted before flowering. If no seeds are to be collected after flowering, the flower stem shall be cut to promote the development of bulb. The cutting position shall be at the top of the flower stem as far as possible. In the first ten days of June, the ball roots can be dug out, spread out and stored in the cold storage in different grades. The temperature in summer should not exceed 28 ℃.
II. Upper basin:
The mixture of loam, saprophytic soil and fine sand is used as nutrient soil. Generally, one ball is planted in a pot with a diameter of 10cm, and two to three balls are planted in a pot with a diameter of 15cm. Then, the pot is buried in the soil. The soil is covered with 10cm-15cm. After 7-8 weeks, when the buds grow to more than 10cm, the soil is removed to make the sun shine. Generally, they are planted from October to November and bloom in March.
In the autumn and winter growth period, topdressing mainly with P and K was applied once or twice. There is no need to apply fertilizer in the flowering period. Before and after flowering, top dressing should be done once respectively, and sufficient base fertilizer should be applied before potted soil planting.
Hyacinth likes the sun and is cold resistant. It is suitable for growing in a cool and humid environment. Therefore, it is necessary to water the soil frequently to keep the soil humidity between 60% and 70%, so as to facilitate the growth and reproduction of hyacinth.
V. light and temperature:
After planting, hyacinth should be placed in the sunny place. It should be exposed to the scattered light for 1 to 2 hours every day to make its leaves and pedicels grow healthily. It should change its direction every day to prevent it from leaning to one side because of the light. If the light is insufficient or the winter is dry for a long time, it will cause poor flowering. If you see that the extracted flower stem is too short and can not extend, you can put potted flower 1 in the dark place for several days to promote the stem and leaf It is too long, and it can be transferred to normal maintenance after the flower stem is extended. The temperature of flower induction should be 5-10 ℃
Glass bottle and plastic bottle with wide mouth and lattice can be selected; the water quality shall be clean and the water shall be changed once a week. If nutrient solution is added, the number of water changes shall be determined according to the turbidity of water. Always add water to keep the water in the bulb.
II. Cultivation method:
There should be 1-2cm space between the water surface and the bulb. Do not immerse the water in the bottom of the bulb. Then place it in a dark place and cover the bottle with black cloth to promote the development of root system. When the root system grows to about 10cm, move it to a warm south windowsill with sufficient scattered light.
III. requirements for water temperature and light:
The water temperature should not be too high, the best temperature is 15-20 ℃. When the leaves and flower buds grow, they are exposed to the sun for 1 to 2 hours every day under the scattered light, so that their leaves and pedicels grow healthily. They change their direction every day, so that they do not tend to grow on one side due to the light, and do not need fertilizer. In March and April of the next year, they can produce a fresh and fragrant hyacinth.
IV. room temperature requirements:
When the room temperature is kept at 17-20 ℃, you will enjoy the process of flower bud formation, growth and color development, but do not put it directly near the place with heat source, so that the beautiful hyacinth flower will extend its opening time
2. Hyacinth can maintain normal physiological activities only when it is exposed to more than 5000lx of light. If the light is too weak, it will cause the plant to be thin and weak, the stem to be too long, the flower bud to be small, the flower to wither early, the leaf to be yellow and so on. The incandescent lamp can be used to supplement the light at about 1 meter; but if the light is too strong, it will also cause the leaf and the petal to burn or the flowering period to be shortened.
3. When the temperature is too high, even higher than 35 ℃, the flower bud differentiation will be inhibited, abnormal growth will occur, and the rate of blind flower will increase; and when the temperature is too low, the flower bud will be frozen.
4. When changing water for hyacinth in hydroponic culture, be careful, because the root of hyacinth is very fragile and easy to be broken, so as not to hurt the root and affect the growth and flowering of hyacinth.
5. Bulbs are toxic. If eaten by mistake, they will cause dizziness, stomach spasm, diarrhea and other symptoms. Therefore, children should be strictly prevented from eating them by mistake.
