Water lily is a kind of common aquatic plant. It grows in shallow water like lotus, but it is more of ornamental value. Many people like to raise water lilies at home, but for novice Xiaobai, the most common situation is that the leaves of water lilies turn black. What's the matter?
I. The reason for the black leaves of water lily:
1. Excessive fertilization will reduce or even stop the water absorption of the leaves, resulting in black and zoom of the leaves.
2. Bacterial infection
3. Insufficient light and too wet
4. The water is dirty or caused by water shortage. (this article is exclusively compiled by WYH, editor of sihai.com. If you need to reprint it, please indicate the source and source. Related article link: http://www.4hw.com.cn/life/zone.html)
II. Solution to the blackness of water lily leaves:
1. If the topdressing is too much, change the water immediately. It should be noted that when changing the water, change the water in half every time, and the water temperature is similar, and the temperature difference is too large, which will lead to the change of pH in the water and affect the water absorption of the leaves. In addition, the basin is turned over and the soil is changed when the base fertilizer is too much
2. Leaf disease can occur during the growth period. To cut off the damaged leaves, spray with 50% carbendazim, 1000 times solution or appropriate amount of pesticide
3. Strengthen sunshine time
4. Direct water exchange can lead to changes in water temperature and acid and alkali. The correct way is to add isothermal water after the water evaporation is less. During the growing season, the water is deficient and the leaves are easy to scorch.
