Can Rabdosia angustifolia be cultured in water?

Tongqian grass can be cultured in water. Tongqian grass likes to be warm and humid, it is better to cultivate in half-day sunshine or shade, avoid direct sunlight, regardless of cultivation soil, it is better to cultivate soil with good soft drainage, or directly cultivated with water, the optimum water temperature is 22-28 degrees. Shade-tolerant, moisture-tolerant, slightly drought-tolerant, strong adaptability, strong nature, easy to plant, rapid reproduction, amphibious. 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 below zero, it will continue to grow in the coming year.

The method of water culture of Rabdosia angustifolia

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

3. 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, and overheating or overcooling will inhibit the growth of Rabdosia angustifolia.

3.Illumination: 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 daily sun exposure time should not be less than 4: 5 hours. In addition, ultraviolet lights or bright fluorescent lamps can also be used instead of sunlight.

4. Fertilization: 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.

5. Insect pests: copper grass generally does not attract insect pests, but molluscs such as water snails may gnaw on grass roots and buds. 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. 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 the light is insufficient 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. When the water raises Codonopsis lanceolata, the yellowing leaves will rot in the water and spoil the water quality, so we should check the water tank regularly and find that the moldy leaves should be pulled out as soon as possible.

6. 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.
