How does ginger grow in water?

Ginger is the fresh rhizome of perennial herbs of Zingiberaceae and Zingiberaceae, and it is an indispensable condiment in the family. It not only can be seasoned and warm, but also has excellent sterilization, anti-inflammation, summer heat and detoxification effect. Ginger has the functions of divergence, antiemetic and antitussive in traditional Chinese medicine. So how does ginger grow in water?

I. the method of hydroponic culture of ginger

1. Selection of species

Choose a piece of ginger, of course, the more beautiful the better, in addition, relatively large, because in the early stage, the growth of ginger seedlings mainly depends on the nutrition of the ginger itself, so if it is too small, it may be malnourished.

two。 Soak in water

Rinse the ginger and shake off the excess water on the surface. This process has two functions, washing clean, hydroponic culture is also more beautiful; second, let the ginger surface contact with water, to help raise seedlings.

3. Container

Choose a container, shallow bowl or glass cup, it is recommended to be more elegant, because the shape of ginger seedlings is very simple. As the root system of ginger is not very developed, it does not need a deep container, and it is not necessary to use a planting basket (as for the planting basket, this is an important tool for hydroponics, which will be discussed in more detail later).

4. Raising seedlings

Put the ginger in the container with shallow water, the height of the water is as shallow as possible, 5mm is enough, do not soak too deep, otherwise the mold will grow much faster than the seedlings.

During this process, it is important to change the water every day and pay close attention to whether it is moldy and hairy. Most of them will grow small white hair, don't worry, just wipe it off gently with a napkin, but you must wipe it off, otherwise, the small white hair will multiply very quickly, and then it will become a piece of rotten ginger.

5. Growth

Ginger does not need to bask in the sun, but must have enough light, is placed in front of the bright window, but there will be no direct sunlight, lack of light, there will be yellow leaves immediately, so this is very important.

Matters needing attention in hydroponic culture of raw ginger

1. Pest control

The main diseases are rot and spot.

The rot disease usually begins in July, and the peak period is from August to September. It is found that the diseased plants are pulled out in time, the diseased soil is dug up, lime is applied in the disease hole, and the soil is buried with clean aseptic soil. 50% chlorothalonil 800 times solution was sprayed at the initial stage of the onset of spot disease, once every 7 to 10 days.

The main pests are ginger borer and ginger maggot, which are controlled by foliar spraying with trichlorfon or phoxim.

two。 Harvest

Wait until around October, when it is the end of autumn, the temperature is slightly higher, the light is sufficient, and the temperature difference between day and night is large, which is the key period for ginger to increase its yield. Properly prolonging the growth period can make full use of the golden period of increasing production in the later stage of ginger. Therefore, we must grasp the good harvest time and must not harvest prematurely.

The above are the methods and points for attention of hydroponic culture of ginger. The harvest time of ginger is usually before the frost season. Before that, we should make a timely harvest. Then the harvested ginger can be preserved reasonably.
