How to feed duckweed? Regardless of whether he can do it?

Purple-backed duckweed, also known as purple duckweed, duckweed, belongs to the duckweed family. The leaves are green and purple on the back, and they grow in paddy fields, ponds, and ditches. In the warm, humid and rainy season, the reproduction is faster, 25 30 is the optimal temperature for growth, and the growth is affected in the high temperature season.

In late autumn, when the water temperature decreases, the purple-backed duckweed grows oval-shaped winter buds, which sink to the bottom of the water for wintering, and the mother dies. In the spring of the following year, the winter buds emerge to the surface of the water and germinate into new individuals, which are the preferred feed for grass carp species. The area of the pond should be 1334-2668 square meters, and the pond or ditch with stable water level, deep sediment and fertile water quality should be selected as the cultivation pond.

Generally, at the beginning of April, the wild trash fish are removed, and 200 kg of cow manure and pig manure are applied as base fertilizer per 667 square meters, and then 100-200 kg of duckweed is put into every 667 square meters. He who has been bred in the previous year can no longer release seeds or less seeds.

The quality and quantity of fertilizer are the key to determining the quality of the cultivation of purple-backed duckweed. In spring and autumn, duckweed reproduces quickly, and should be applied more top dressing, and when the temperature is high, it can be applied less. If the plankton in the pond is reduced, the transparency is large, and the duckweed takes root more, it is due to the lack of water quality and fertility, and it should be applied appropriately and diligently; On the contrary, it can be applied in moderation.

Generally, manure is applied once every 5 days. After the pond is full of duckweed, it can be fished, and the number of each fishing can not exceed 30 of the totalPurple-backed duckweed generally produces 20-30 tons per 667 square meters, and the yield can be increased if the temperature is suitable and the water quality is fertile.

Duckweed has a high nutritional value, and it contains 91 water, 1 6 protein, 0 8 fat, and 6 6 other organic matter. The protein and fat content are higher than those of other aquatic plants. Duckweed is an excellent bait for grass carp.

This plant originally lives in the water, just like the river and lake water, it can grow well, so, as long as the water conditions can be the same as those water, it can grow well, the river and lake water is flowing, the amount is large, and the nutrient supply in it is sufficient, but the nutrition in the water used to raise duckweed must not keep up, so you can change the water after a few days, or you can add some nutrient solution in moderation. Duckweed needs sunlight to grow, so give it sunlight!

Raise it in a more fertile place, don't care.

It's okay, let it see the sun less.

My family's water hibiscus, you have to bask in the sun, still water, don't need to change the water often, open-air breeding, more than 20 days two plants into 10 plants?

Duckweed can be used as food for fish and can also have a shading effect. The disadvantage of farmed duckweed is that the duckweed will cover the fish tank after being placed in large quantities, which will affect the entry of light, and will cause the fish to lack oxygen when breathing at night. Breeders need to control the number of duckweed in the tank, and clean it up in time when the duckweed grows to a certain number.

Duckweed raised in the orange sedan chair in the fish tank can be used as food for the fish, and can also play a shading effect, and can increase the oxygen content in the fish tank, make the water quality clearer, so that the fish can grow and develop better.

The disadvantage of raising duckweed is that after a large number of duckweeds reproduce, it will cover the fish tank, which will affect the entry of light, and it is not convenient to watch, and breathing at night will consume oxygen, which will lead to a lack of oxygen in the fish, which is not conducive to its growth and development.

When the duckweed grows to a certain number, it needs to be cleaned up in time, and the appropriate amount of duckweed can meet the growth needs of the fish.

Duckweed must ensure sufficient water, and often change the water for the plant attack, duckweed is poor in cold tolerance, and it needs to be moved indoors in winter to keep warm, to ensure that the ambient temperature is not less than 5. It is also necessary to give it sufficient light, place it in a well-lit place for maintenance, and prune its branches and leaves in time to ensure the growth of the plant.

Duckweed is an aquatic plant, the growth of the plant must ensure sufficient water, when breeding duckweed potted plants, it needs to be changed frequently to ensure the growth of the plant. The water is changed once a week in spring and autumn, once every 2 days in summer, and once every 10 to 15 days in winter.

Duckweed likes a warm environment, the most suitable temperature for growth is about 20 25, and its cold tolerance is poor, and it must be moved indoors for thermal insulation when breeding in winter. Ensure that the ambient temperature is not lower than 5 and the water temperature is not lower than 10, so that the plants can successfully overwinter.

Duckweed likes light, the growth of the plant needs sufficient scattered light, it must be placed in a place with better lighting for maintenance, spring, autumn and winter can give it full sun maintenance, to ensure the growth of the plant needs.

The growth rate of duckweed is very fast, and it is necessary to cut off its stunted, long, and diseased branches and leaves in time during daily maintenance to avoid unnecessary loss of nutrients, so that the plant grows more lush.

1. Light conditions, duckweed likes the sun to accompany the chain very much, so we must always put it in a sunny place to cultivate it in the usual maintenance, otherwise if it often does not absorb enough light energy, it will cause the leaves of duckweed to begin to turn yellow, which seriously affects its aesthetics. In the usual maintenance, we can let the duckweed bask in the sun, and even need to let it shine all day long in the spring and autumn growing season, because the oxygen consumption of duckweed at this time will be very large, if it can not be replenished in time, it is easier to stop it to grow. The sunlight is very strong in the summer of each year, and if the duckweed is still exposed to the sun at this time, it is easier to get sunburned, so we must pay attention to it in time at this time.

2. Temperature conditions, we need to understand that the most suitable temperature for duckweed to grow should be between 25 degrees and 30 degrees, in this temperature range its growth rate will become very fast, and the overall development will be better, we should usually control the growth temperature in this temperature range. Duckweed is a kind of cold-tolerant plant, in winter we need to help it to control the cultivation temperature above 10 degrees, to avoid it because of the low temperature growth environment and some frostbite such health conditions, which will affect the duckweed to survive the winter safely, and can affect the growth of the next spring growth period.

3. Prune in time, the growth rate of duckweed, such as duckweed, is very fast, as long as we can usually give the right temperature and light, they will grow very large and dense in a short time, so we have to prune duckweed at this time, first of all, if you encounter some bad locust leaves, or yellowing leaves, we can help it cut off, help it reduce the loss of nutrients, if there are too dense leaves also need to help prune, cut it a little sparsely. It is best not to use scissors when pruning, because the wounds caused by it are more difficult to recover and are more likely to be infected by germs in the air and water during the period.

4. Correct filling and changing water, duckweed is a typical aquatic plant, we can use the tank to cultivate it at home, we need to pay attention to one point when filling water, that is, about the water level of cultivation, can not fill too much water, can not be too little, generally from the bottom of a 10 cm or so. When we cultivate duckweed, it is best to help it change the water every week or so, otherwise the nutrient content in the water will be relatively low if it is used for too long, which will lead to insufficient air absorption of duckweed, which will directly affect its growth.

1. Planting: When the water temperature reaches about 18 °C, the plant can be planted continuously. Plants can be planted in pools or large containers, or in water tanks, wooden barrels, plastic pots, fish tanks and other containers that can hold water.

2. Temperature: like low temperature, the most suitable temperature for development is 25-30 °C, about 28 °C when the reproduction is very fast, you can add 1 times the number of plants within 2-3 days, nearly 10,000 plants can be reproduced within about 1 month, and the water temperature should be improved as much as possible during the growth period. If it is not cold-resistant, the development is stopped before winter and enters the dormant period, and the strong plants should be planted in peat soil first, and they should be kept moist and overwintered in a bright greenhouse.

Perhaps the plants are wintered in warm water and reserved for propagation the following year. During the wintering period, the water temperature should be insisted on 5-10 °C, and the air temperature should not be less than 0 °C, otherwise it will lead to frost damage.

3. Light: like enough sun, the planting container should be placed in direct sunlight, without obvious shade of the sun. When there is a lack of light, the leaves of the belt will turn yellow.

4. Water: It can drift in water, and the roots can also grow in mud when it is shallow. When planting, you should put plenty of water in the container to prevent it from drying out.

The water in the later stage of cultivation is slightly shallow, which is conducive to the advance of water temperature and the development and reproduction of plants. In the early stage, the temperature decreases, and the water can be deeper to maintain the right water temperature.

5. Fertilization: Because of the fast development rate, a small amount of nutrients is needed to ensure its normal development. The growth period is especially the vigorous development period, and nitrogen-based fertilizer should be applied once a month.

6. Pruning: Because the reproduction rate of plants is fast, it is easy to form plant congestion during the vigorous development period and affect the development and appreciation, so weak seedlings, diseased seedlings and overly dense plants should be removed in real time to make the plants develop strongly.

Duckweed is an aquatic plant that usually grows on the surface of water. Although duckweed can provide a shelter and habitat environment for fish, duckweed itself is not suitable as the main feed or growth environment for fish. If you want to raise fish, it is recommended to choose aquatic plants or fish food suitable for fish growth.

The old and young people will not sell it today, and directly announce that the answer is to use duckweed to raise ornamental fish in still water, even if it is lazy, they can raise fish well.

Duckweed is generally not suitable for direct fish farming because duckweed is an aquatic plant whose main role is to absorb nutrients, oxidize waste, and provide shade in the water. However, duckweed can be stored with fish farming and play some beneficial ecological roles, such as:

Water Quality Improvement: Duckweed can absorb some waste and excess nutrients in the water, helping to improve water quality and reduce pollution of water bodies.

Provide shade: Duckweed can create a floating cover on the surface of the water, providing some shade that helps regulate the water temperature and reduce the growth of algae in the water, while also providing a hiding place for fish.

Oxygen**: Duckweed produces oxygen through photosynthesis to provide additional oxygen to aquatic organisms.

Although duckweed can coexist with fish farming, there are a few things to keep in mind:

Controlled growth: Duckweed can grow rapidly at times, and if left unchecked, can overgrow in water columns, preventing light from penetrating the water and adversely affecting aquatic plants and fish. Therefore, excessive duckweed needs to be cleaned or cut off regularly.

Ensure water quality: Duckweed is not a complete substitute for proper filtration systems and water quality management. When raising fish, there is still a need to monitor the water quality to ensure that it is suitable for the survival of the fish.

In conclusion, duckweed can coexist with fish farming as a part of aquatic plants, helping to improve the ecological balance and water quality of water bodies. However, in the process of fish farming, the growth of duckweed needs to be properly controlled and managed to ensure the stability of the water environment and the health of the fish.

Duckweed is an aquatic plant, and it can be planted as an ornamental plant in life, and it is best to choose clean and nutrient-rich waters when planting duckweed. Duckweed has high requirements for temperature, it is best to control the water temperature at 20 30 degrees when planting, duckweed grows very fast, and there is no need for too much maintenance when planting.

Duckweed belongs to the duckweed family aquatic plants, mostly distributed in temperate regions, often planted as ornamental plants, that duckweed can raise flowers, usually can not use duckweed to raise flowers. The leaves of duckweed are symmetrical, and its leaves are very round, mostly green, which has a certain ornamental value and is very suitable for planting in lotus ponds.

Duckweed has high requirements for water quality, suitable for growing in paddy fields, ponds or still water, it is best to choose clean and nutrient water when planting, and try not to choose waters with many impurities. Duckweed grows very fast, very suitable for group planting, planting duckweed to control the amount of plants, each planting should not be too much.

Duckweed is a plant with great utilization value, its whole plant can be used as medicinal materials after processing, its medicinal value is very high, can be used for edema, rheumatism, heat toxicity, impermeable rash and other symptoms. Duckweed is a cool ingredient, and its greatest effect is to clear heat and detoxify, so people with weak constitution should be cautious.

Duckweed is a high-quality feed, which can be added to ordinary feed to feed poultry together, which can speed up the growth of poultry and make poultry meat better. Duckweed is neither cold nor heat tolerant, it has high temperature requirements, and it is best to control the water temperature at about 20 30 degrees when planting.
