Embodiment 1
[0046] An ecologically efficient three-dimensional planting method for ponds, comprising the following steps:
[0047] A. Pond conditions: Choose a pond with sufficient water sources, fresh water quality, no pollution sources, convenient transportation, supporting power, and independent inlet and drainage systems. The pond covers an area of 8 mu, the bottom of the pond is flat, and the water depth is 1.5-2.0m.
[0048] B. Please clean the pond: Drain the pond water in winter, remove excess silt, keep the silt depth at 20-30cm, and it is best to expose to the sun.
[0049] C. Stocking fish species in ponds:
[0050] (1) Clear ponds: 7 to 10 days before the fish species are stocked, clear the ponds thoroughly with quicklime, with an amount of 150 kg per mu.
[0051] (2) Release: The following fish species will be released on March 1:
[0052] ①Grass carp: The specification is 20 fish / kg, and the stocking amount is 19 kg / mu.
[0053] ② Silver carp: The specification is 35 tai...

Abstract
The invention provides a pool efficient ecological stereoscopic plantation and breeding method. A net cage is arranged in a pool, ricefield eel is bred in the net cage, water spinach is planted on the net cage, a bio-floating bed and the richfield eel breeding net cage are combined into one, a large quantity of freshwater fishes are bred and mandarin fishes are interbred outside the net cage, and thus an efficient ecological system with a material cycle and automatic purification is constructed. By utilizing solar energy, the water spinach absorbs nutrient materials of nitrogen, phosphorus and the like in pool water through developed root systems, the grown water spinach can serve as fish feed, and can also be used as a vegetable to be eaten by people. Through the purification effect of the water spinach on the water body, the water quality can be improved, the fish disease occurrence rate can be reduced, the medicine dose can be reduced, and the quality safety of the aquatic product can be improved. By breeding the ricefield eel in the net case, by stocking a large quantity of fishes in the pool and by interbreeding the mandarin fishes, the water surface resource is fully utilized, and the pool utilization rate is remarkably improved. The yields of famous and superior aquatic products and the water spinach are increased, the investment in water, electricity and medicine is reduced, and the economic benefit is increased by a large margin. Meanwhile, the pool efficient ecological stereoscopic plantation and breeding method has the effect of producing scenery, saving energy, reducing discharge and beautifying the environment.
Description
technical field [0001] The patent of the invention belongs to the technical field of aquaculture, and specifically relates to an efficient ecological three-dimensional planting and breeding method for ponds. Background technique [0002] At present, the main breeding method of pond fish farming in my country is multi-species polyculture, mainly grass carp, silver carp, bighead carp, crucian carp, bream, herring, etc. Due to the rising price of breeding inputs such as feed, the cost of breeding is increasing year by year, and the breeding benefits are getting lower and lower. Some even suffered losses. In order to improve economic benefits, the breeding density has been continuously increased. Due to the high breeding density and the extensive use of feed fertilizers, the breeding water environment has deteriorated, and fish diseases have occurred frequently, leading to blind use of drugs, which seriously threatens ecological security and aquatic product quality and safety. I...
