Why do the leaves of aquatic plants turn yellow? What should I do?

There are bacteria in the water, physiological dehydration, lack of sunlight, low temperature, and insufficient nutrients; When processing, the impurities inside should be cleaned first, ensure that there is a certain amount of sunlight, increase the temperature, and appropriately sprinkle some nutrients in the water.

Because the chlorophyll of the leaves is gradually lost, it will turn yellow, so it must be ventilated frequently, watered properly, and ensure the right temperature, and the temperature must be kept above 20.

It may be caused by not being exposed to sunlight and not photosynthesizing. I think you can plant them in a sunny place.

The first reason for the yellowing of the water plant tank is the lamp, if the color temperature of the lamp is below 6500K, it will look yellow. 8500-10000K light is cold. The configuration of aquatic plants with a variety of color temperature lamps has a better effect, generally with a 6500k and two 10000k or so, this configuration of general aquatic plants can be raised.

In addition, the spectrum of the lamp is very important, and it is more reliable to choose the brand of lamp!

In fact, sometimes the aquatic plant tank is not yellow but green, not emerald green, and it looks yellow with light irradiation.

This situation is caused by the growth of green moss on the walls of the tank. There are three ways to cause this green moss.

1: Direct sunlight irradiates the aquatic plant tank, which is the fastest reason for the production of green moss algae, so neither the aquatic plant tank nor the fish tank can let the sunlight shine directly on the tank.

2: If the light is turned on for too long or the power of the lamp is greater than the demand of the water grass tank, the light opening time and the power of the water grass tank can be appropriately reduced. The power conversion of the water plant lamp is multiplied by the volume of the fish tank, which is the amount of power required per liter of water.

3: Long-term non-water change and overfeeding. Aquatic herb tanks, like fish tanks, need to be fixed to change water, the main purpose of which is to replenish the mineral content lost in the water and reduce the content of nitrate and nitrite.

In addition, the fish in the aquatic plant tank are only supported by feeding a small amount to maintain the minimum needs of the fish. The accumulation of leftover fish food in the fish tank after a large number of feeding can generate a large number of harmful substances, thereby destroying the ecological environment in the tank and directly affecting the health of plants and animals. And it can produce protein worms, which are disgusting but harmless.

Therefore, a good grass tank needs to be equipped with suitable lights, and it is important not to feed a large number of creatures in the tank, and it is important to change the water regularly!

Is the yellowing of the leaves of aquatic plants just because of the high water temperature? Actually, no, I have sorted out 7 reasons for you, you can use the elimination method to find the reason for the yellowing of the leaves of aquatic plants.

Fertility exceeded. Aquatic weed mud is generally used in the grass tank, as the bottom bed and plant fertility**, the aquatic weed mud in the early stage of the tank, the fertility release rate is faster, which will lead to the yellowing of aquatic weed leaves, and even melt the stem, the best way is to strengthen the water exchange.

If you are not using aquatic weed mud, you can consider adding too much basal or liquid fertilizer.

Fertility is insufficient. If your fish tank uses a bed with no fertility at all, the aquatic plants cannot absorb nutrients, and the leaves will turn yellow, then the best solution is to add root fertilizer to the bottom bed, or use a comprehensive liquid fertilizer.

The light is too strong. Plants and people, also need to rest, the light is too strong or the continuous light is too long (more than 48 hours), the leaves of aquatic plants will not only yellow, and even fall off, the solution is very simple, shorten the light time, generally 8 hours shall prevail.

Lack of light. The fish tank light is very important, it is the key to allow the aquatic plants to photosynthesize, if the light source is weakened, the photosynthesis stops, the aquatic plants will first turn yellow, then rot the leaves, and finally the whole aquatic plants will die. The solution, using professional straw tank lamps, the worst, can also ensure the normal growth of aquatic plants.

Irregular lighting.

The most worrying thing is irregularity, the fish tank light timing switch can solve your problem, so that the work and rest of the aquatic plants are also regular, in order to show you the perfect side.

The water temperature is too high. At the beginning of the article, we talked about the water temperature of the fish tank, which is the most difficult problem to solve, and the best way to solve it once and for all is to use a chiller, or put the fish tank in an air-conditioned room, and other methods seem to be difficult to solve this problem.

The fertilizers needed to grow aquatic plants include basal fertilizer, root fertilizer, liquid fertilizer, iron fertilizer, and other trace elements. The equipment required includes aquatic plants, light pipes, biochemical filters, biochemical filter cotton, heating rods, and complex cooling systems, timers, and pH values, which may cause yellowing if these conditions cannot be hit.

There are many reasons, environmental reasons, and nutrient deficiency reasons.

The yellowing and rotten leaves of aquatic weeds may be caused by the low water temperature, and a heating rod can be placed in the water tank to stabilize the temperature between 20 and 25. It may also be caused by a lack of light, and aquatic plants need to be moved to a bright place for maintenance. It may also be caused by soil discomfort, and it is necessary to choose natural neutral and weakly acidic river sand soil for planting aquatic plants.

The yellowing and rotten leaves of aquatic weeds may be caused by low temperatures. If the water temperature in the fish tank is too low, and if the water temperature is unsuitable for a long time, the aquatic plants will stop growing, and the leaves will turn yellow when the growth is restricted. If the temperature of the water tank is low, you can place a heating rod in the tank to stabilize the water temperature between 20 and 25.

The condition of yellowing and rotten leaves of aquatic weeds may also be caused by the lack of light, aquatic weeds have a greater demand for light in the growth process, and the lack of light aquatic weeds cannot carry out photosynthetic farming, which will also affect the synthesis of chlorophyll, which will make aquatic weeds appear yellow and rotten leaves. At this time, the aquatic plants need to be placed in a bright place for maintenance, and the aquatic plants can synthesize oxygen through light to resume growth as soon as possible.

The yellowing and rotten leaves of aquatic weeds may also be caused by soil discomfort, and if the soil is alkaline or too sticky, it will cause aquatic weeds to appear yellow leaves. Therefore, when cultivating aquatic plants, it is necessary to choose natural neutral and weakly acidic river sand soil for planting, so that aquatic plants can grow healthily.

Aquatic weeds have a greater demand for nutrients in the growth process, and if there is a lack of nutrients, the growth rate of aquatic weeds will slow down, the growth will also deteriorate, and the leaves will turn yellow and fall off in the later stage. At this time, it is necessary to add an appropriate amount of nutrient solution to the water tank, or the compound fertilizer rich in nitrogen, phosphorus and potassium elements can be diluted with water to form a fertilizer solution and poured into water.

1. In the first case, the nutrients are not enough for the aquatic weeds to lack the nutrients for growth, so they become yellow and the ears are poor, and the aquatic weeds should be fertilized, and the fertilizers that can be selected are basal fertilizer, liquid fertilizer, root fertilizer, etc.;

2. In the second case, the light time and light intensity are not enough, resulting in the inability of aquatic plants to photosynthesize, so the light of aquatic plants should be carried out regularly and quantitatively every day, and the light time should be controlled within 6 to 8 hours at least;

3. In the third case, the total ion concentration in the water is too high due to the excessive fertilization of the branches, and the water should be changed regularly and the amount of fertilizer applied should be controlled;

4. In the fourth case, the roots or petioles are damaged, resulting in the leaves being unable to absorb nutrients and turning yellow, the damaged and yellowed aquatic plants should be directly removed, waiting for the new roots to grow out, improve growth, and then use ceramsite, aquatic grass sand or river sand to spread on the bottom of the water to fix the aquatic weeds.

Problem description: I have added water and fertilizer and light, but the aquatic plants still have yellow spots or the whole piece turns yellow.

What should I do?

Analysis: 1. It is possible that insufficient lighting may lead to necrosis of aquatic plants.

2. The aquatic weeds have not been watered before entering the water, resulting in inconsistent water temperature and water quality, and the necrosis of aquatic weeds.

3. When you buy old grass, it is easy to rot roots and leaves.

4 The varieties of aquatic plants are inferior, especially in Guangzhou, most of them are water leaves, and it is normal for them to turn yellow and rot leaves in water.

5 Another problem may be the water quality, the hardness and pH of the water will directly affect the growth of aquatic plants.

Generally speaking, tap water is drinking water, and the hardness and pH are neutral, and the impact will not be so obvious (except for excessive chlorine).

Of course, there are many other reasons that affect the growth of aquatic plants.

Solution: Cut off the yellowing leaves, avoid high temperature (direct sunlight) and see if you can sprout.

The water still has to be beaten out and cooled for 2 or 3 days before being put into the water tank as well.

Summary. Pro, the treatment method for yellowing the leaves of aquatic plants in the fish pond is as follows: 1

Check the water quality: exclude the influence of water quality factors. Test the pH value, dissolved oxygen content and other indicators of the fish pond water, and adjust the water quality in time.

2.Ratio of aquatic grass carp: If the number of aquatic grass carp is large and the number of fish is small, then the number of stocked fish can be increased, so that their feces and nutrients such as carbon dioxide produced by metabolism can better nourish aquatic plants.

3.Fertilization: Use appropriate aquatic weed fertilizers to replenish aquatic weeds, such as:

Turtle droppings. 4.Cleaning:

To remove foreign matter and microorganisms from the surface of aquatic plants, it is recommended to take out aquatic plants and wash them and place them in clean water to return to normal.

Dear, thank you for the addition to the question. 1) The water quality and environment of yellow eel cage culture are very important for the health and growth of yellow eel. Yellowing of the leaves indicates that there may be a problem with the water quality or environment of the eel cage, which may be related to a lack of nutrients, insufficient light, and other factors.

2) Here are some suggestions on how to make water peanut leaves green:1Increase Lighting:

Lack of light is one of the common causes of yellowing of leaves. Installing suitable plant lamps in the eel cage and controlling the light time can help provide enough light to meet the needs of peanut leaf growth. 2.

Add fertilizer: Adding appropriate fertilizer to the peanut tree to supplement its scarce nutrients can promote the greening and growth of leaves. Suitable types of fertilizers include sediment and liquid fertilizers.

3.Maintain water quality: Yellow eels produce feces and sediment, which must be removed regularly.

Creating an environment of water temperature, water frequency, acid, alkali and salinity indexes that conform to the growth habits of eel is helpful to provide good growth and nutrient conditions. 4.Controlling the Temperature:

Peanuts are suitable for growing in the range of 15 to 25 senses, and maintaining a stable water temperature can help promote the growth of peanut leaves in the eel cages, avoiding premature wilting or yellowing that may occur at high or low temperatures.

Insufficient lighting leads to necrosis of aquatic plants, cut off the yellowing leaves, and avoid high temperature (direct sunlight) to re-sprout. Light is the first condition for raising aquatic plants, and in the aquarium, sunlight hits the aquatic plants from all sides, so that the intensity of light in the aquarium is stronger than that of the middle and lower layers of natural water.

At the same time, different aquatic plants also have different requirements for the intensity of light and irradiation time, and strong light is needed to live and grow well. Such as Newton grass, red chrysanthemum grass, etc., this kind of aquatic grass in the case of insufficient sunlight during the day, fluorescent lamps should be used to extend the light time at night.

It can grow well in low light, such as net grass, orchid grass, sunset pepper grass, green chrysanthemum grass, etc.; These aquatic plants should not be exposed to direct sunlight and should be shaded with a mulch. The aquatic plants in between, such as foxtail grass and European crown grass, can be exposed to morning and evening sunlight as long as they are exposed to the sun.

Is it because there is not enough light time, is it dry?

Just take care of it.

Is it in the fish tank, maybe the temperature is low and the temperature is a little warmer.
