Houttuynia cordata Thunb how to hydroponically cultivate Houttuynia cordata Thunb

Houttuynia cordata can not only be used as medicine, but also can be eaten. Because Houttuynia cordata Thunb has high nutritional value, it is generally eaten with cold dishes, but it can also be used as a seasoning to make dishes. Houttuynia cordata is very popular in the south, so it is widely planted, at the same time, many potted friends like to plant it as a potted plant.

Houttuynia cordata can not only be cultivated in soil, but also can be cultivated in water. However, for Houttuynia cordata cultivated in soil, the rhizome is slightly yellowish, the stolon is not easy to clean, and its taste is relatively light. And hydroponic houttuynia cordata, not only the rhizome fat, white and tender, whether used in medicine or edible, its value can often be better reflected. So, how to cultivate Houttuynia cordata in water? Next, the editor will share with you how to cultivate Houttuynia cordata in the water.

For growers, due to the need for large-scale cultivation and mass production, but considering that Houttuynia cordata grows slowly and needs to grow in shade and sufficient water environment, soilless cultivation technology can be adopted, and the yield is often 3-4 times that of soil culture. Therefore, soilless cultivation is a very good way to increase yield.

But as family potted users, we can hydroponically cultivate Houttuynia cordata Thunb, using transparent containers to grow, we can clearly see its growth process. And the rhizome of Houttuynia cordata Thunb is very white, stout, and highly ornamental. Therefore, family hydroponic culture of houttuynia cordata is often a good choice.

Many people think that Houttuynia cordata Thunb is not an aquatic plant, so it can not be raised in water. Original but through practice, it is found that Houttuynia cordata can be hydroponically cultivated. However, in order to make Houttuynia cordata grow fat, we need to make scientific use of hydroponic nutrient solution to provide a variety of nutrients for plant growth. And as long as we go to the market to turn around, we can often see many businesses put hydroponic Houttuynia cordata for sale.

Because Houttuynia cordata Thunb has the characteristics of humidity and waterlogging tolerance, although most of the plants can not be planted below the water surface, the lower part of its rhizome can be left under the water surface. The upper part of the rhizome can remain on the water surface in the bottle, so that the rhizome can absorb not only the dissolved oxygen in the water, but also the oxygen in the air. Here are the technical points of hydroponic culture of Houttuynia cordata Thunb.

1. Hydroponically cultured Houttuynia cordata, the height of the water level line should not exceed 2/3 of the transparent glass bottle. If the water level is too high, most of the roots of Houttuynia cordata will be submerged below the water surface, and the dissolved oxygen in the water is limited, which will cause some difficulties to the breathing of the roots, which is very disadvantageous to the growth of Houttuynia cordata Thunb.

2. During hydroponic culture, attention should be paid to keeping the water quality in the bottle clean, because the deterioration of the water quality will cause the rhizome of Houttuynia cordata to rot, thus forming a vicious circle and eventually leading to plant death. Therefore, changing water frequently is an important safeguard measure.

In general, the temperature in spring and autumn is relatively suitable, and the water can be changed every 5-7 days; while in summer, the temperature is relatively high, and the water should be changed more frequently, usually every 3-5 days; in winter, because the temperature is too low, the water quality is not prone to corruption, so it is generally possible to change the water every 10-15 days. The amount of water replaced each time should account for 2/3 of the total amount of water in the original bottle. It is not necessary to replace all the water every time, otherwise it will cause a waste of resources and is not very beneficial to the growth of the plant.

3. Changing water is the key link of hydroponic culture of Houttuynia cordata Thunb, and each change of water should be combined with dripping nutrient solution. Then gently shake the water and nutrient solution, which can also increase the dissolved oxygen in the water, which is more conducive to the breathing and growth of the rhizome of Houttuynia cordata. But do not drop too much nutrient solution each time, otherwise it may burn out the rhizome of Houttuynia cordata Thunb because of high nutrient concentration, generally dripping a few drops. This can not only avoid fertilizer damage, but also meet the nutrients needed for the growth of Houttuynia cordata Thunb.

4. Usually maintenance and management should choose a suitable position, not only to ensure smooth ventilation, but also to ensure that the environment is not directly exposed to sunlight. But generally, it still needs to be placed in the sunny place, after all, the plant needs photosynthesis to promote growth, generally let it receive scattered light, so as to avoid the phenomenon of overgrowth caused by the lack of light in the environment.

However, if it is a sunny day in winter, it is recommended to move hydroponic Houttuynia cordata outdoors to receive light for about an hour to accelerate photosynthesis and increase the water temperature in the bottle, which is more conducive to the growth of hydroponic houttuynia cordata.
