Harm of overwatering or insufficient watering to flowers and preservation methods of edible fungi

When the potted flowers are watered too much, the water fills the soil gap, and the air in the soil is replaced by water, so the external air can not enter, which results in soil anoxia, hindrance of root respiration, decrease of physiological function and hindrance of root water and fertilizer absorption. At the same time, due to the lack of oxygen in the soil, a large number of aerobic bacteria with the function of decomposing organic matter in the soil multiply and move, which increases the acidity of the soil. Due to the extensive activities of butyric acid bacteria, a series of toxic substances such as hydrogen sulfide and ammonia were produced, which directly poisoned the root system. At the same time, anoxic plants consume a large amount of soluble sugar and accumulate too much alcohol and other substances, resulting in a great decrease in photosynthesis, and finally make flowers die of hunger. In the practice of flower cultivation, we can often see examples of flowers being "drowned" due to overwatering, resulting in blackening and decay of flowers' roots. Therefore, we should pay attention to the right amount of watering when cultivating flowers.

Potted flowers due to less soil, water storage is not much, in the flower growing season need to pay attention to often replenish water, in order to ensure the normal growth of flowers. If the water supply is insufficient, the leaves and petioles will shrink and droop, and the flowers will wilt. If there is a long-term insufficient water supply to the flowers, the leaves of the older and lower parts of the plant will gradually yellowing and dry up. If most grass flowers are in a state of drought for a long time, the plants are short, the leaves lose their bright green luster, and even the whole plant dies. Some flower growers are afraid of excessive watering, watering "half-waist water" every time, that is, the amount of water can only moisten the topsoil, while the lower soil is dry, this watering method will also affect the root development of flowers, and there will also be the above-mentioned bad phenomena. Therefore, watering should be dry and wet, and it should be watered thoroughly.
