Speaking of the topic of vegetable growing, we can never finish talking about it. With the development of agricultural technology, some new vegetable growing models have emerged. The more popular ones are fish and vegetable symbiosis. The high-yield, low-water and fertilizer operation mode is also advocated by the state. , The perfect combination of aquaculture and hydroponic cultivation, one acre of land earns two acres of land, realizing the benign interaction of fish farming without changing water and no water quality problems, growing vegetables without fertilizing and normal growth. A rural guy has tried fish for many years. The vegetable symbiosis finally succeeded, and the greenhouse of 2 mu of land earned 200,000 yuan a year.
Fish and Vegetable Symbiosis
There are many cases of symbiosis in agricultural planting. There are fish and rice symbiosis, duck and rice symbiosis in the field, lotus root and shrimp intercropping in the pond, and the fish and vegetable symbiosis in the greenhouse are played out by a rural boy. There are rows of rows in the greenhouse. Vegetable three-dimensional cultivation shelves, the annual output of vegetables is 4 crops higher than the traditional vegetable growing model. A one-mu greenhouse produces 10,000 jin of fish a year, and the output of vegetables exceeds 30,000 jin, realizing both vegetable and fish farming. How to achieve income generation, fish and vegetable symbiosis? In terms of sales, which models he combines, let's take a look.
Principles of fish and vegetable symbiosis
The biggest difficulty in achieving aquaponics symbiosis lies in the balance. In order to maximize the income of vegetables and fish, the rural guy has obtained a data after many experiments. One square meter of vegetables needs 1.3 kg of fish to provide nutrients, and too many fish can not fully absorb vegetables. The excrement and nutrients in the water, and the excrement of fish returning to the fish pond will be detrimental to the growth of the fish. After the vegetables growing in the planting tank are pulled out, the water quality becomes turbid and it is not very healthy for the fish. The fish will die. Vegetables and fish The balance is particularly important.
Pollution-free vegetables
In 2017, Bater, a rural guy from Inner Mongolia, took his wife back to his hometown of Dingyuanzhai Town, Guan County, Liaocheng City, Shandong Province. He invested more than 4 million and developed two high-efficiency fish and vegetable symbiosis greenhouses in the greenhouse water with a variety of fish. Different kinds of fish eat different fish foods, which will produce different fish manures, which are collected and separated from dry and wet. After biochemical decomposition, the mineral elements that can be absorbed by vegetables are poured in from the end of the vegetables and slowly returned from the front end. In the fish pond, the water quality is purified after the vegetables absorb minerals, realizing a synergistic symbiosis.
Two benefits per mu of land
The growth of fish and vegetable symbiosis vegetables is soilless cultivation. Many people say that they dare not eat this kind of vegetables. In fact, the growth of vegetables absorbs the trace elements of minerals. Without the use of chemical fertilizers and pesticides, there will be no pesticide residues. The prevention of diseases and insect pests in rural areas uses physical means. , The temperature in the shed is controlled by a smart heater. In order to improve the yield and quality of vegetables, a laser plant supplement light is installed. One set is used for one shed. It can fill up the light for 8 hours a night and only consumes 10 kilowatts of electricity a month. The laser can extend the light. It can also sterilize and repel insects.

The remote operation of the intelligent mobile phone in the greenhouse allows Battelle to manage it easily. Fish and vegetables not only need to be sold, but also sold at a price to make money. Does the symbiosis of fish and vegetables mean that selling vegetables and fish for profit? This is the case, but the rural guys have created a diversified development pattern of "sightseeing + picking + private ordering" of fish and vegetable symbiosis. Some fruits suitable for picking are planted in greenhouses. The price of pollution-free fish farmed is more expensive than that in the market. , Through tourists' leisure picking, buying and other modes, so that the greenhouse can realize rapid income.
Fish and vegetable symbiosis ecological restaurant
According to relevant statistics, the fish and vegetable symbiosis system saves 90% of water compared to traditional agriculture. The output of aquaculture is 10 times that of traditional agriculture, and the output of vegetables is 10 times that of traditional agriculture. The rural guys are full of confidence in the prospect of fish and vegetable symbiosis. He now sells vegetables and fish through large supermarkets and restaurants to make a profit. The production capacity is relatively limited and he cannot accept a large number of orders. Next, he wants to make a fish and vegetable symbiosis into a plant factory, which is more than 700 flat in supermarkets, restaurants and other places to eat. With picking.
Vegetables can also be cultivated in three dimensions
The symbiosis of fish and vegetables can greatly shorten the growth cycle of vegetables, avoid diseases and insect pests, and make the transition from planarization to verticalization of vegetable growing, so that many urban families can experience different pastoral life without leaving home ...
