Modern agricultural aquaponics intelligent greenhouse project
Aquaponics, that is, in a agricultural greenhouse, the circulation can grow vegetables and fish, and the feces of the fish are converted into ammonia nitrogen under the action of heterotrophic bacteria, and the water mixed with human feces is pumped into the vegetable planting tank, producing nutrients that affect the bioabsorbability of the plant. The waste water from the fish pond needs to be filtered through its own planting tank, turned into fresh water and returned to the fish pond, and so the development cycle repeats.
Here is a brief introduction:
Fresh vegetable aquaponics has six advantages: hydroponics for all, no pesticides, high nutritional value, scientific picking, fresh visible, both ornamental value, green safety, green, healthy characteristics, since entering the market, it has been welcomed by people.
aquaponics
The vegetables in aquaponics can also be replaced with melons and fruits for tourists to pick in leisure agriculture.
Fish farming is a combination of growing organic fruits and vegetables, planting honeydew melon, cantaloupe, watermelon, etc., with a high density of combined aquaculture fish, crabs, shrimp and other aquatic products, can be achieved without ecological cultivation of fertilizer and pesticide pollution and organic agriculture.
Greenhouses can also be based on the actual situation and the cultivation of strawberries and other suitable for picking fruits, the price of farmed fish is also higher than the price of ordinary products in the Chinese market, by improving the tourists' leisure picking, buying and other models, so that the overall greenhouse to achieve corporate profits.
Fish, vegetable and fruit symbiosis
When it comes to scientific picking, we may be relatively unfamiliar, and common words are mechanized picking, automatic picking and so on. What is "scientific picking"? Scientific picking is the use of scientific methods to pick vegetables in order to minimize the content of nitrite in vegetables.
The nitrite content of fresh fish lettuce is very low, but general vegetables use too much nitrogen fertilizer during the growth process, resulting in high nitrite, so lettuce (such as vegetables with fish and vegetables) will not use nitrogen fertilizer to grow. To a much lower level, so we use the scientific method, between 2 and 3 p.m. every day, to make choices using the scientific method.
Coupled with speed distribution, aquaponics maximizes fresh, natural, pollution-free vegetables to protect your health and your family.
In this information system, the biggest feature is "fish do not change the water, planting vegetables do not fertilize."
The traditional way of fishing, the most well-known surface about 20cm below, but here, the fish pond water is clear. In the construction of the aquaponics system in the remaining nine state farms in agriculture, the water in the pond is pumped by water grass tanks, fish dung microorganisms and earthworms through decomposition into nutrients that can be absorbed by the plant, purified water through the planting tank back to the pond, etc. In addition to water loss through evaporation and plant transpiration, water needs to be added in small amounts periodically, and it does not require changing the pool.
