1, the roots of plants can absorb a large number of harmful substances nitrate, reducing the impact of harmful substances on fish.
2. Plants can release more fresh oxygen through photosynthesis.
3. Green plants add beauty to the home environment and make the environment look brand-new.
Extended data:
1, breeding and ornamental
Aquatic plants have beautiful shapes, bright colors and elegant postures. They are planted in aquariums and decorated with river sand and heavy wood. They look beautiful and generous, and become one of the best decorations and appreciation items in the aquarium. Xia of Luye Aquarium Supermarket said that it takes some efforts to cultivate aquatic plants.
2. Sediment selection and fertilization
Natural neutral and weakly acidic river sand should be used as bottom sand for planting aquatic plants, and alkaline ordinary sand should not be used, so as not to hinder the normal growth and survival of aquatic plants. In the process of aquatic plant cultivation, some special nutrient solutions beneficial to fish and aquatic plants should be supplemented in time to promote the growth of aquatic plants and a good ecological balance in the tank.
3, lighting light and time
The lighting condition of aquatic plant landscaping trough is not suitable for natural light, and simulated sunlight should be used, which is suitable for plant growth (the market price is generally around 20 yuan ~ 100 yuan/root, and Three Lamps District is generally needed for one meter trough). Just after planting aquatic plants, the light should not be too long to prevent algae from multiplying. After planting for one week, it can be normally illuminated for 6-8 hours every day.
4, * * * put fish, feed the fish.
Big fish: such as parrots and arhats. , can arch grass, can eat grass, will destroy the landscape effect of Tanqueray. Therefore, it is best to avoid breeding these big fish in aquariums with aquatic plants, and it is best to breed some small fish with beautiful colors. In order to avoid water pollution, the principle of feeding several times is maintained, and the ornamental effect of fish and grass is achieved.
5. Water temperature
Water plants in different habitats have different requirements for water temperature, and tropical water plants have higher requirements for water temperature. For example, the suitable water temperature of iron crown is 20-28 degrees, that of flowers and plants in Huang Ju is 24-28 degrees, and that of kelp is 22-28 degrees. The requirements for temperate aquatic plants are relatively low. For example, the suitable water temperature is 14-22 degrees, Saxifraga 16-24 degrees, and Sagittarius can safely spend the winter at a water temperature above 4 degrees. So generally speaking, the water temperature is 20 to 24 degrees. Tropical aquatic plants, the winter water temperature is not lower than 15 degrees.
Therefore, the aquarium in northern winter should have heating rods or thermostats to keep the water temperature. However, the thermal insulation device should not be too close to aquatic plants, so as to avoid the death of aquatic plants due to excessive water temperature. If possible, you can use a pump to circulate the water in the aquarium. Conducive to heat distribution and the growth of aquatic plants.
6. Matrix
Coral sand, coarse sand, gravel sand, dolomite and other materials are all good substrates. There is a big gap between these sand materials, which is beneficial to the root growth of aquatic plants and can purify water without muddy water. In the choice of substrate, substrate should never be used, because the gap between substrates is too small and the oxygen supply is insufficient, which is not conducive to root growth and is easy to cause root rot; At the same time, it is easy to muddy the water and affect the photosynthesis of aquatic plants. Before laying, the bottom material should be cleaned strictly with clear water, and then soaked in salt water or potassium permanganate solution for disinfection. Finally, it can only be used after thorough cleaning.
7. Look
Planting aquatic plants should be layered and mixed with many kinds of plants. At the same time, we should consider the different requirements of different aquatic plants for light, water temperature and water quality. In terms of layout, we should strive to be uneven and patchwork; The positions of aquatic plants, rocks and heavy trees should also be balanced, and the picture should be harmonious, and the plants should be tall and long. Behind the rock, lush aquatic plants should be planted as the background, such as crown grass, seaweed, evergreen and so on.
Some aquatic plants with shorter stems should be planted in the gap as the middle scene, such as banyan, nettle grass, watermelon grass and so on. Some creeping aquatic plants are suitable for the future, such as Lysimachia christinae and Lentinus edodes. The planting density of aquatic plants should not be too high, and a certain distance should be left, so that the pictures can be coordinated and the scenery combination can be perfect.
