Water culture overwintering method of specular grass:
First of all, we should have a simple understanding of it: it has strong cold resistance. The most suitable temperature is 16 ° C to 20 ° C. if the temperature drops to - 4 ° C, it will frostbite the plant and its leaves will become dull p>
1. Change water
The interval of water change during breeding in winter can be extended. Generally, the water change can be carried out once every 10 to 15 days in spring and autumn, and once every 20 days in winter p>
When changing water, it is best to put the water in the sun for half a day. If there is no sunshine, it should be put for one to two days. But if you choose pure water, you can use it directly. However, the temperature is low in winter, so no matter what kind of water, the water temperature should be equal to or not much different from the original water temperature in the vessel before changing the water, which is conducive to the health of plants p>
When changing the water, observe the root. If there are other foreign matters covered, wash the root with clean water and put it back into the vessel. If necrotic root is found, trim it together with the water change p>
During hydroponic culture in winter, the amount of water should not be too much. The height of water can completely soak the whole root in it p>
2. Nutrition
If the temperature drops to 10 degrees in winter, the concentration of nutrient solution should be reduced to the usual 1 / 2 or 1 / 3, or even the application can be suspended p>
Special reminder:
The temperature control in winter plays a very important role in the growth and health of plants, so we must pay attention to keep it p>
