Why is it not successful to raise aquatic plants? What are the correct planting methods of aquatic plants?

In the process of fish and shrimp culture, the existence of aquatic plants is very necessary, but for many farmers will experience the failure of aquatic plant cultivation, so why is it not successful? What are the correct planting methods of aquatic plants?

First, why is the cultivation of aquatic plants not successful?

1. The water temperature is too high or too low

The suitable temperature for most aquatic plants is between 18 and 30 ℃. Beyond this temperature, many species of aquatic plants will grow poorly or wither and die.

two。 Water quality pH value is too high or too low

The physiological phenomenon of aquatic plants will be affected by the pH of water quality. As long as the pH value is too high or too low, aquatic plants will inhibit the absorption of nutrients and water and affect their growth and development.

3. High hardness of water quality

High hardness of water quality means that the concentration of calcium in water quality is high, and aquatic plants living in an environment with high calcium will hinder its absorption of other nutrients, which is not conducive to the growth of aquatic plants.

4. Disharmony of light quality

The wavelength of illumination light affects the photosynthesis of aquatic plants. For example, among the seven monochromatic lights, only red and blue light are the most effective for photosynthesis of aquatic plants. If these two wavelengths are too small in the components of the lighting source, it is difficult for aquatic plants to photosynthesize.

5. The lighting is too weak.

Although aquatic plants can also carry out photosynthesis in weak lighting, the efficiency of photosynthesis is very low and can not produce photosynthates (carbohydrates) that aquatic plants rely on for survival.

6. Lack of nutrients

Aquatic plants need fertilizer as well as other plants. Without fertilizer, aquatic plants cannot assimilate and grow.

7. Lack of carbon dioxide

Carbon dioxide is an essential raw material for photosynthesis of aquatic plants. Without enough carbon dioxide, aquatic plants can not carry out photosynthesis at all. Insufficient content of carbon dioxide will reduce the efficiency of photosynthesis, so aquatic plants can not survive for a long time.

8. It is not the "aquatic plant" of aquatic plants.

Some terrestrial water-tolerant plants are not suitable for long-term growth in water, but they can survive in water for a period of time, but eventually die in water. These water-tolerant plants are usually not easy to photosynthesize in water and rely solely on their original stored nutrients to maintain their growth, so when these nutrients are exhausted, that is when they face death.

Originally, this water-tolerant plant should not be sold as an aquatic plant, but because of its attractive appearance and the fact that it does not die immediately when planted in an aquarium, it is often used as a short-term layout material for some aquatic plants and cultivated in a half-water landscape. Therefore, there are still some unwitting aquatic enthusiasts to buy and plant this kind of water-tolerant plants. Therefore, it is recommended not to buy this kind of "aquatic plants" as far as possible, they can not be successfully cultivated in aquariums, and can only be used temporarily as "living decorations" in aquatic plants.

Second, what are the correct planting methods of aquatic plants?

1. Cylinder planting method

Lay fine river sand with a thickness of about 3cm at the bottom of the cylinder, then open a hole to press the whisker root into the sand, and then fix it with some goose soft stone to prevent it from being pulled up when changing water. This method can be well laid out, but it is more troublesome to clean. This method makes the layout perfect, but cleaning is more troublesome. Crown grass, asparagus, water chrysanthemum and other water plants that take root at the bottom are more suitable.

two。 Pot planting method

Is to plant water plants in a small basin, and then put the small pot into the tank, which is equivalent to a pot in a fish tank. Although this method is easier to clean, the layout is more limited. Aquatic plants suitable for pot planting are also suitable for potted plants.

3. Floating planting method

Just put the water plants into the tank. If you want to fix it, you can also press it to the root, tie the root of the water plant with a small stone or put it into a suitable glass tube to sink into the bottom of the cylinder and fix it with a small stone. This method is more suitable for rattan aquatic plants such as goldfish grass, centipede grass and so on.

Generally speaking, the planting technology of aquatic plants is relatively easy to use. If you are interested, you can try it yourself.
