Guide to the hydroponic culture method and maintenance group of Zhu Dinghong

Zhu Dinghong can also be called safflower, Guding flower, Baizhilian, trumpet flower, belongs to perennial bulb herb, Zhu Dinghong plant is 20-30cm high, and its flower color is orange, red, light red, white or with stripes. Next, the editor will talk about Zhu Dinghong's hydroponic culture method and maintenance group guide.

1. Hydroponic culture method

(1) method 1

Dig up the whole plant of Zhu Dinghong seedlings cultivated in soil, peel off the formed tiller buds next to the mother plant, rinse with clean water and plant in a transparent container, inject fresh water into 3 places of the root system, wait 2-5 days, and then change the fresh water.

(2) method 2

Select the whole plant of Zhu Dinghong seedlings cultivated in strong soil, remove the rotten roots, rinse them with clean water, disinfect and plant them in a transparent container, inject fresh water, change the water every 2-3 days, remove the shrunken and rotten roots when changing water, and wait 7 days for horizontal hydroponic cultivation of Zhu Dinghong seedlings to grow new roots.

2. Maintenance guidelines

(1) temperature and light

The most suitable temperature for the growth of Zhu Dinghong is 18-25 degrees, and the most suitable temperature for dormancy is 10-12 degrees. The safe winter temperature should not be lower than 15 degrees, otherwise it will inhibit the growth of Zhu Dinghong. When the temperature is below 0 degrees, the plants will suffer frost damage.

Zhu Dinghong likes places where there is warm and sufficient scattered light, but she avoids strong direct sunlight.

(2) changing water

In the initial stage of Zhu Dinghong hydroponics, the water can be changed every 2-3 days, and after 30 days, the water can be changed every 5-7 days.

When the top is red, it should be placed in a well-ventilated and bright environment near the window.

(3) fertilization

If it is used as a short-term cultivation of Zhu Dinghong, because the bulb contains nutrients needed for growth, it is possible to open an account without adding nutrient solution. If it is for long-term cultivation, add nutrient solution every 30 days.

(4) Disease and pest control

Water culture Zhu Dinghong is the most prone to root rot, so once the root rot is found, the rotten roots should be removed in time, and Zhu Dinghong should be washed clean and replanted. For insect pests, manual capture is the main method.

Hydroponic culture and post-anthesis treatment of Zhu Dinghong

Zhu Dinghong is a very important flowering plant, more than half of which are planted in pots, but many people choose hydroponics. The hydroponic Zhu Dinghong blossoms with snow-white roots when it is semi-soaked in glass water, and its green leaves set off bright flowers. It looks particularly elegant and beautiful. the following editor will tell you about the culture method of Zhu Dinghong hydroponics:

Water culture method of Zhu Dinghong:

Step one: pick the ball

Generally, it is necessary to select more than 3-year-old Zhu Dinghong (the bulb is more than 6 cm), cut off all the leaves before autumn frost, and control water to promote its dormancy (dormancy period is not less than 25 days or 50 days before Spring Festival, late, it is difficult to see flowers before the festival).

Step 2: colonization

The bulbs are washed with a 1000-deep permanganate solution, and the old roots and impurities are removed, and then planted in a daffodil basin (put clean coarse sand or pebbles to fix the new roots). If you use glassware as a wall hanging, you can not put sand or stone. The water only needs to soak the seed ball for a small half.

Step 3: transplant

After the 0.5CM or so root of the bulb grows, move the bulb into a clean water culture container and straighten it with a water culture frame. The water depth should be half of the immersion bulb, and finally put it in a sunny place indoors.

Step 4: maintenance

1. Temperature: the best temperature for Zhu Dinghong to grow indoors is 20 ℃-25 ℃, and it is better not lower than 15 ℃. The cooler temperature will delay the growth and flowering time of Zhu Dinghong.

2. water change: check the culture bottle regularly and change the water in time. Change the water every 2-3 days in the first half month, and then every 4-5 days. The water level in the basin is always kept at the original water level.

3. Fertilization: in order to make Zhu Dinghong plants grow better and bloom more brightly, when the leaves grow to 2-3CM, they can be fertilized regularly, adding 1% urea solution or 0.03% potassium dihydrogen phosphate or other compound fertilizer solution containing nitrogen, phosphorus and potassium every 10-20 days.

Post-flowering treatment of Zhu Dinghong in hydroponics:

1. Soil culture

The hydroponic culture of Zhu Dinghong is simple and easy, similar to the method of daffodil culture. However, after hydroponic culture of daffodils, the bulbs are withered, nutrients are exhausted, and they cannot blossom the following year, while hydroponic Zhu Dinghong can be moved into the basin soil to continue cultivation when the day is warm after flowering. At that time, as long as more water and fertilizer are applied, they can quickly recover their vitality and become strong seedlings, according to this continuous hydroponic culture in winter.

2. Pruning and maintenance

When the flowers of Zhu Dinghong begin to decline after fully blooming, cut off the scape from the 2CM of the stem, so as not to compete for nutrition from other developing scape or leaves, while not harming the leaves, which maintain healthy and exuberant photosynthesis can produce and accumulate nutrients for re-flowering in the following year. The red leaf shape of Zhu Ding is very beautiful, even after the whole flower, it can also be used as a green plant to observe the leaves, and when the weather turns warm, it can be moved into the pot soil to continue cultivation.

Many people think that Zhu Ding red water culture is more suitable for home layout and beautification than soil culture. When Zhu Ding red flowers bloom in water culture, they can watch not only the peculiar red flowers of Zhu Ding red flowers, but also the red and green branches and leaves of Zhu Ding, as well as the snow-white roots in glass bottles, which give people a refreshing and clean feeling together, which has an unexpected effect in home layout.

Can Zhu Dinghong be cultured in water? the method of water culture in Zhu Dinghong

Zhu Dinghong likes a warm, moist and sunny environment, which requires cool summer and warm winter. It is a flowering plant, which is cultivated in soil and seldom raised in water. If it is half-immersed in water, the snow-white roots and green leaves set off the brightly colored flowers, which is particularly elegant and beautiful. Many flower friends have asked Zhu Dinghong can be hydroponic, what is the method of Zhu Dinghong hydroponics? The following editor will answer for you.

Can Zhu Dinghong be cultured in water?

Zhu Dinghong can be hydroponically cultivated, and hydroponic Zhu Dinghong is very simple. In early winter, choose one or more blooming or unflowered big balls, cut off all the roots and leaves of Zhu Dinghong, peel off the black-brown skin of the outer layer, reveal white and green, and soak in clean water. After about 48 hours, take out the red ball of Zhu Ding, wash off the paste of the incision with clean water, dry and put it into a prepared container.

The containers of Shuipeizhu Dinghong can be bowls, pots or daffodils, etc., put into washed pebbles, perlite, water-absorbing rocks, etc., and then put on the treated Zhu Dinghong bulbs. Then pour in clear water, preferably clear spring water (if tap water is used, it must be placed for a few days). The depth of the water should be about 1 cm lower than that of cushions such as pebbles or flower utensils.

At room temperature about 10 ℃, leaves and roots began to grow in about 7-10 days. The water in the basin should always be kept at the original water level. At the end of the next spring, the bulbs with roots were planted in flowerpots for routine maintenance. In this way, the hydroponic bulbs bloom a little later than other conventional potted plants, just in time for the summer blooming period.

Water culture method of Zhu Dinghong

1. Temperature: the best temperature for hydroponic growth of Zhu Dinghong indoors is 20 ℃-25 ℃, preferably no less than 10 ℃. The cooler temperature will delay the growth and flowering of Zhu Dinghong.

two。 Change water: check Zhu Dinghong's culture bottle regularly and change the water in time. Change the water every 2-3 days in the first half month, and then every 4-5 days. The water level in the basin is always on the original water level.

3. Pruning: when Zhu Dinghong's flowers begin to decay after full bloom, cut off the scape from the 2cm of the stem, so as not to compete for nutrition from other developing scape or leaves, and do not harm Zhu Ding red leaves. Keeping leaves healthy and exuberant photosynthesis can produce and accumulate nutrients for re-flowering in the second year.

4. Fertilization: when the leaves grow to 2-3 cm, fertilizers should be added in time, and 1% urea solution or 0.03% potassium dihydrogen phosphate solution or other compound fertilizer solution containing nitrogen, phosphorus and potassium should be added every 10-20 days.

The above is the article that Zhu Dinghong can be cultured in water, and the method of water culture. In order to make the red flowers bloom better, you might as well add a little inorganic fertilizer to the newly changed water after the scape outcrop every week to make it a very thin inorganic liquid fertilizer. When the scape grows to about 3 cm, raise the ambient temperature to about 25 degrees. When the bud is about to open, put the plant in a cool place with an ambient temperature of about 10 degrees, which can make the red flower more colorful and bloom longer.
