Embodiment 1

[0044] Embodiment 1 device

[0045] A device for planting vegetables, rice, and flowers in combination with net cage cultivation, including: floating blocks, net cages, cultivation containers and fasteners;

[0046] Described net cage is the circular container (see image 3 ) or square container (see figure 2 ), the top of the circular container is tied with a waterproof fishing net rope 1, and the galvanized round steel pipe (2.5-3 centimeters in diameter) is the keel, and the bottom is a glass wire mesh 3.

[0047] The square net cage includes a loam cake net 4, the loam cake net is movable, and is used for putting fry and fishing for finished products, and the bottom insertion net 5 is used for fixing the connecting surface of the frame net, and the frame net 6 is connected with the meat under the loam cake net , the main keel 7 is a galvanized steel pipe with a diameter of 2-6cm.

[0048] A floating block is arranged on the net cage, and the floating block is a foam boar...

Embodiment 2

[0053] The apparatus of Example 1 was used.

[0054] 1) Set up net cages in the lake, stock fish fry in the net cages and raise 10-30 fish per cubic meter of net cages, and the size of the cages is 80-120 grams. Ecological fish do not need to be fed. They eat aquatic vegetables, roots of aquatic flowers and The proportion of microbes flowing in the draft water, fish and plants: 15 small fish weighing 80 grams in one cubic meter net cage, the corresponding plant planting ratio is: 100 water plants: 60 aquatic plants. Fish species: silver carp, bighead carp, grass carp, carp, crucian carp, eel, loach, snakehead, squid bream and non-crucian carp.

[0055] The cages are located in the backwater bay of the river, with a water depth of 3 to 5 meters. Avoid areas overgrown with water and grass, and the water flow velocity is in the range of 0.05-0.2 m / s. The top of net cage places floating block, and floating block is placed in the net cage, is connected with floating board net cag...

Embodiment 3

[0071] If the feeder is fixed in a 60*50 cm automatic feeding machine in the middle of the aquatic plants, start feeding 2-3 times a day, and the start-up time is 5-10 minutes.

[0072] Compared with Example 2, the cost of feeding is higher.

Abstract

The invention provides a vegetable, rice and flower planting and net cage intercropping combination device. The device comprises a floating block, a net cage, a cultivation container and a fastening piece; the net cage is a circular or square container which is formed by a nylon net in a surrounding mode and does not have the top face, the floating block is placed at the top of the net case, and the cultivation container is placed on the floating block. By means of a vegetable, rice and flower planting and net cage intercropping combination device, pesticides are not needed, and the vegetable and rice planting cost is low; in addition, the environment is easily protected, a water body is purified, and economic benefits are generated through ponds and lakes. When the method is adopted for planting vegetables and rice and culturing fishes, ingredients such as nitrogen, phosphorus and potassium contained in the ponds and the lakes are absorbed by the cultured products and are microelements needed by the human bodies, nutrition is abundant, and the quality of the products is better than that of products cultured in land for growing field crops.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a fish farming method combined with planting. Background technique [0002] In southern my country, fish can be stocked in ponds or rice fields with certain water sources and better water quality and good drainage and irrigation conditions. After careful feeding, each mu of rice fields can produce 400kg of rice, and about 200kg of crab fish, achieving the effect of double harvest of rice and fish. [0003] Soilless cultivation of plants on the water surface is an agricultural technology that has developed rapidly in recent years. For the natural environment with a lot of surface water in southern my country, we should develop water surface planting technology to improve economic income and environmental quality. Soilless cultivation of paddy rice on water, combined with underwater net cage cultivation, is a mode that has not yet been tried in the prior art. [0004] The ...
