Notice of copper coins.

1. Water quality

Water quality has little effect on Codonopsis lanceolata, but to keep it in fresh water with low hardness, the water should be kept slightly acidic. You don't need to change water too frequently, you can change it once a week, of course, you can change water often in summer, as long as there is a strange smell in the water, you can pour out some of the water and add some new water. The leaves that fall in the water should also be cleared out in time. If tap water is used, it is best to rest for two hours.

two。 Light

Copper grass needs the right amount of light, usually 4 hours, but do not be directed by strong light.

3. Temperature

The preferred temperature is 15-25 ℃. If the temperature is too high or too low, it will slow down its growth.

4. Fertilizer application

Fertilization is extremely important for copper grass. Generally speaking, we have to add flower fertilizer to it in two or three weeks, and we also have to give it a special nutrient solution.

All right, the above are the methods and points for attention of hydroponic culture of copper grass, let's try to cultivate them quickly.

Matters needing attention in hydroponic culture of Rabdosia angustifolia

Tongqian grass is a kind of lovely and easy-to-grow foliage plant, and it can purify indoor air and bring good fengshui, so it is very suitable for family viewing. Today, I would like to introduce the hydroponic culture methods and matters needing attention of Tongqian grass.

Hydroponic culture method of Rabdosia angustifolia

1. Water quality

Tongqian grass does not have high requirements for hydroponic water quality, as long as it does not cause smelly insects, it can be hydroponically cultured directly with ordinary tap water. Change the water about 3-4 days in summer, half of the basin at a time, and 1/3 at a time in winter.

two。 Fertilizer application

Rabdosia mandshurica can produce the necessary nutrients for growth through its own photosynthesis, so it can fertilize less. If you need to apply fertilizer, you can use ordinary chemical fertilizer water to dissolve in the water basin, let it absorb itself, but pay attention to the amount is not too strong, a small amount can be.

3. Light

Codonopsis lanceolata is extremely fond of sunlight when it grows, so it is best to put the basin outside or by the window where there is plenty of light. If cultivated indoors, the sun exposure time should not be less than 4-5 hours per day. In addition, ultraviolet lights or bright fluorescent lamps can also be used instead of sunlight.

4. Temperature

Rabdosia angustifolia is suitable for production in most hot and humid areas of the south, especially in summer. Its normal growth temperature is between 10 and 26 degrees Celsius. Overheating or overcooling will inhibit the growth of Rabdosia angustifolia.

5. Reproduction

Rabdosia angustifolia is generally propagated by ramets, which is disconnected in the place where the stolon takes root with scissors in summer, and the former plant can be transferred to other water basins to reproduce. In addition, in summer, Rabdosia przewalskii will produce small flowers, and then the seeds can be used to propagate new plants.

6. Insect pest

Copper grass generally does not attract pests, but molluscs such as water snails may gnaw on grass roots and buds, and if such insects are found in the water, they should be removed by hand to prevent them from reproducing in large numbers.

Matters needing attention in hydroponic culture of Rabdosia angustifolia

1. Tongqian grass hydroponics is suitable for extensive cultivation, as long as it is given enough sunlight and water, it can grow very fast.

two。 If there is no sunshine indoors, lights can be used instead.

3. Water needs to precipitate tap water for two hours, or use it every other day.

4. You can add a little nutrient solution to the water.

5. The hydroponic culture of Rabdosia angustifolia generally has yellow leaves, but its withering rate is far less than the growth rate, so don't worry.

6. The hydroponic root system of Rabdosia angustifolia grows green algae, but it can not be cleaned.

7. As long as the water is not rotten, just add water to it and spray some water on the leaves regularly.

The above is for you to introduce the water culture methods and points for attention, do you understand? Please pay attention to more household knowledge.

Methods and matters needing attention in hydroponic culture of Rabdosia angustifolia

In recent years, hydroponic plants have become very popular. Among hydroponic plants, hydroponics can be said to be at the top of the pack. Because of its simple and close-to-people nature, it has become a favorite family decoration plant for many flower friends and even ordinary people. the following is a detailed method of hydroponic culture.

The method of hydroponic culture of Rabdosia angustifolia

1. There is no need to change the water very frequently. Under the premise that there is enough water in the basin, you can change it once a week. If you can change water more frequently in summer, it is mainly to prevent mosquitoes from laying eggs in it.

2. Keep enough light and receive more than 4 hours of sunlight every day before the grass can grow luxuriantly and verdant. Rabdosia angustifolia is particularly fond of the sun and can grow rapidly even if it does not release fertilizer in sufficient sunlight; on the other hand, if it is not bright enough or kept in a dark room for a long time, its leaves will easily turn yellow and wither.

3. There is no need to pay much attention to fertilization. If you have goldfish at home, you can pour the water from the goldfish into the basin, which can make the goldfish grow better.

4. In the south, if you grow well in the temperature range of 16-24 ℃, you can survive naturally. However, too high or too low temperature will inhibit the growth of Rabdosia angustifolia, and bugs are more likely to sprout in the water at high temperatures.

5. The vigorous growth of Rabdosia angustifolia can spread all over the water basin in a month, so we should prune and branch it properly and transplant the overdense Rabdosia angustifolia to other water basins, so as not to block the light of the young leaves and affect the normal metabolism of plants.

Methods of hydroponic cultivation of Rabdosia angustifolia

1. Cut several segments of stems, each with at least 3 nodes, and cut off too many leaves appropriately. After rinsing with water, put it into the container, pay attention to the position and soak the walking stem in water as much as possible (it is best to use tap water that has been kept for more than 2 days).

2. Before the new roots grow, put the container in a bright environment as much as possible, be careful not to be exposed to direct sunlight, and clean up the rotten stems and leaves at any time.

3. During the period of hydroponics, some nutrient solutions can be added to the water to maintain the needs of the plant growth period. For friends with high aesthetic requirements, you can put some crystal balls, pottery or pebbles, but not too dense, to give the root system normal growth space.

4. After about a week, the new roots begin to grow, and then the light can be increased for normal management.

5. if the leaves turn yellow, pay attention to the use of nutrient solution or spraying nitrogen-based compound fertilizer to the leaves several times a week. When water moss appears in roots and leaves, change the water immediately and clean the container, otherwise it will be disadvantageous to the plant and affect its ornamental ability. Usually, we should pay attention to whether there is enough water in the container to avoid drying up.

6, the phototaxis of copper grass is very strong, pay attention to change the orientation of the container, otherwise the leaves are easy to grow askew to one side, affecting beauty.

7. Rabdosia angustifolia grows faster, and when the plants are more dense, it can be transplanted into a larger container, or it can continue to be cultivated without permission in the original container, but pay attention to giving enough nutrients.

8. If the old leaves turn yellow, they can be cut off in time; if they grow to a certain extent, pedicels will be drawn out, and some of them can be cut off.

9. Tongqian grass is afraid of the cold. If you put it outside in winter, you can pour out all the water. If you put it in a place facing south and leeward, you can survive the winter safely, but some of the leaves will die, and the underground roots will sprout again next spring. If there is no heating in the cold areas of the north, you can make a cover with a basin, pour out the water and keep it moist. As long as the room temperature is not lower than zero, it will continue to grow in the coming year.

10. In the early stage of cultivation, you can drop some nutrient solution into the water every day, and when the grass grows vigorously, you can appropriately reduce the number of drips.

11. To ensure that the grass has enough light, when the light is not strong, you can put it outside or on the windowsill to shine on the sun.
