What if the water plants turn yellow?

The role of aquatic plants in the aquarium can be said to be pivotal, in the aquarium, aquatic plants will also carry out photosynthesis. In fact, it is not difficult to raise aquatic plants, but many fish friends will find that their aquatic plants begin to yellow after raising for a period of time, and they still don't know how to save them. Let's take a look at how to do the yellow aquatic plants!

Not enough nutrients.

[Symptoms] If there are not enough nutrients, the aquatic plants will lack nutrients for growth. If they do not absorb nutrients, the aquatic plants will turn yellow.

[Method] When the nutrients are not enough, it is necessary to fertilize the aquatic plants. The fertilizers that can be selected include base fertilizer, liquid fertilizer, root fertilizer, and other trace elements. The root fertilizer and base fertilizer are mixed into the middle sand when paving the sand. Fertilization is a step before planting aquatic plants, and cannot be added after planting aquatic plants. The reason is that the base fertilizer and root fertilizer are mixed evenly when spreading sand, which is conducive to the uniform absorption of aquatic plants.

insufficient light

[Symptoms] The main reason for the yellowing of aquatic plants is that due to insufficient light time or insufficient light intensity, the aquatic plants cannot carry out photosynthesis, and the aquatic plants will slowly change or die.

[Method] The lighting of aquatic plants should be carried out regularly and quantitatively every day. The lighting time required for normal growth is about 6~8 hours, and the lighting needs to be carried out at a fixed time every day.

physiological dehydration

[Symptoms] In mild cases, the leaf shape will become smaller and appear dark green, especially the young leaves cannot be unfolded and curl. In severe cases, the tip and edge of the young leaves will begin to rot, gradually spreading to the old leaves, and finally the whole plant will wither and die. The main cause of physiological dehydration of aquatic plants is artificial excessive fertilization, which makes the total ion concentration in water too high.

Regular water change and monthly fertilizer application control are necessary steps to avoid physiological dehydration of aquatic plants.

sun exposure

[Symptoms] Different varieties of aquatic plants have different requirements for light intensity. Many kinds of aquatic plants will grow poorly or wither and die if they exceed the temperature limit.

[Method] Do not put it in direct sunlight, and use a cover to shade it.

temperature is too high

[Symptoms] Gas accumulation in diffusion barrels will lead to reduced dissolution efficiency, and leaves of aquatic plants with insufficient carbon dioxide will be easily burned by strong light. After burning, it is easy to yellow, and the temperature is too high. The water plants are also easy to yellow leaves, showing that the stems or leaves are wrinkled and twisted, and the growth morphology of the water plants is abnormally raised. The leaves are withered or deciduous. The stems and leaves dissolve and rot.

[Method] Fan can be used to cool down.

temperature is too low

[Symptoms] Decreased metabolic function, causing growth stagnation or atrophy. The physiological changes of tissues were abnormal, and the leaf receptacle tissues disintegrated to form dead leaves or leaves. Partial or complete necrosis of aquatic tissue, resulting in rotting symptoms of roots, stems, or leaves.

[Method] Generally, the water temperature is more suitable at 20~24℃. For tropical aquatic plants, the water temperature should not be lower than 15℃ during winter. Therefore, in the northern winter aquarium should have a heating rod or thermostat to maintain water temperature. However, the insulation device should not be too close to the aquatic plants, so as not to cause the death of aquatic plants due to high water temperature. Conditions can be used to raise water, so that the aquarium water circulation state. It is beneficial to heat distribution and also beneficial to the growth of aquatic plants.

Root rot causes

[Symptoms] The roots or petioles are damaged when the seaweed is bought back. This will cause nutrients to reach less than the leaves, it will be yellow. If the petiole's damaged, that leaf's dead.

[Method] It is recommended to fold it directly, and the roots will be improved if they are damaged and grow out. It is recommended to fix the aquatic plants with ceramsite and aquatic sand or river sand as bottom sand, so that the roots will not be crushed and the roots of the aquatic plants can be extended smoothly.

caused by pests.

[Symptoms] When the fungus infects the aquatic plants, the leaves initially appear water-like brown spots, then gradually yellow, and even the whole plant leaves are fibrous dissolved in water, if in contact with healthy leaves, it will soon be infected. The main cause of this disease is that the water plants are infected by bacteria due to high temperature during transportation. Then, when the buyer bought the weed, he mixed the infected plants with healthy ones.

If it is not removed in time, it will be planted in the water tank, and the bacteria will soon spread. One is to cut off infected leaves or stems in time. If the cluster type of aquatic plants, remove the diseased leaves, separate them in another container, and observe the progress of the disease. Once new symptoms are found, immediately soak them with 0.2~0.5 mg/g copper sulfate to kill pathogenic bacteria. The second is to reduce the water temperature of the water tank to below 20 ° C to control the reproduction of pathogenic bacteria.

Summary: found that after the yellow water plants can be appropriate to add fertilizer, fertilizer including base fertilizer and liquid fertilizer, and pay attention to observe the water quality, especially PH value, and daily feeding, whether the light is reasonable, not too much light can not be too little. If you want your aquarium to have a higher viewing value, you need to pay patience. Although it is not particularly difficult, it is not a very simple thing.
