How to raise water lotus
Water hyacinth, also known as water hyacinth, water hyacinth seedling, cloth bag lotus, floating lotus, originated in Brazil, is now distributed in the Yangtze and Yellow River basins of China. So how to raise water lotus? Let's have a look together!
First, how to raise water-floating lotus
Water lotus likes to grow in a warm and humid environment, the most suitable water temperature is 18-23 degrees; it can also grow above 35 degrees, and the temperature will stop growing when the temperature is below 10 degrees. The change of water and fertilization should be determined according to the growth situation, and should not be sprinkled directly on the seedlings when topdressing.
2. What are the hazards of water lotus?
1. Blocking waterways, affecting shipping and excretion, and becoming the number one enemy of agriculture, water conservancy and environmental protection.
2. The flow of the water body is restricted, and the water body becomes smelly without sunlight, which reduces the amount of dissolved oxygen in the water body, inhibits the growth of plankton and destroys the ecological environment of the river.
3. It provides a breeding ground for bacteria such as Schistosoma japonicum and encephalitis and influenza, breeds mosquitoes and flies, and provides opportunities for mosquito larvae to breathe and reproduce.
4. Destroy drinking water resources. Due to the blockage, the water body can not flow freely, various pollution sources such as heavy metals and other trace elements harmful to the human body can not be effectively removed, and people absorb the polluted water source directly or indirectly.
5. covering the water surface also increases the evaporation of water, which is 8-10 times higher than that of the open water surface, resulting in the loss of water source.
6. The influence on the fresh water quality of the source water intake point. A large number of water floating lotus covering the water surface will reduce the PH value of water; increase the concentration of CO2; increase the olfactory concentration and chromaticity of water; and increase the acidity of water, so that the use value of water resources is greatly reduced until it is undrinkable.
