Greenhouse ecological circulation three-dimensional planting system and method thereof

Abstract

The invention discloses a greenhouse ecological circulation three-dimensional planting system and a method thereof in pond culture technology. An organic vegetable cultivation device is directly abovea fish farming pond. Sludge water at the bottom of the fish farming pond is pumped into a mixing tank. Sludge water is pumped in a filter device for filtration. The ammonia nitrogen concentration ina nitrogen water pool is read by a first ammonia nitrogen concentration detection device. The nitrogen water in the nitrogen water pool and the water in the mixing tank are pumped into the fish farming pond. The water in the nitrogen water pool is pumped into a first nitrogen water reserve pool. The water in the first nitrogen water reserve pool is pumped into the organic vegetable cultivation device for being absorbed by vegetable. The ammonia nitrogen concentration in a second nitrogen water reserve pool is read by a second ammonia nitrogen concentration detection device. The nitrogen waterin the second nitrogen water reserve pool is pumped in the fish farming pond. The nitrogen water is recycled into the fish farming pond. The invention carries out secondary circulation absorption andutilization of the sludge water in the fish farming pond, and realizes the automatic circulation of water resources and nitrogen resources. The utilization ratio of water resources and nitrogen resources is high, and the automatic integration of the ecological circulation system can be realized.

Description

technical field [0001] The invention relates to pond culture technology, in particular to an ecological cycle three-dimensional planting and breeding system, which is easy to implement in small farms. Background technique [0002] In the traditional breeding process, due to the input of a large amount of bait, harmful substances such as nitrite and methane are produced, and the feces of fish are mainly discharged in the form of nitrogen. The nitrogen element in the pond will be particularly rich, which will easily lead to eutrophication of the pond water. The problem of causing saprophytic bacteria breeds, causing fish infection and even death, reducing fish production and economic benefits. In view of the above problems, the existing technology is to dig ecological circulation ditches around the pond, build an orchard, and after processing such as filtration and sedimentation, the wastewater from the fish pond is drawn out through the ditches to plant fruit trees, which pro...

Problems solved by technology

However, because the pond orchard is distributed in a large area and the investment is too large, it is difficult to realize small farms; moreover, the sewage from the pond is once irrigated to the orchard, which cannot be used twice, and the utilization rate of water and nitrogen resources is low; at the same time, due to the overall The ecological cycle system requires huge human resources, which increases labor costs, reduces economic benefits, and violates the concept of modern automatic integration. Therefore, it is very costly and difficult to realize the automatic integration of such a large area of ​​ecological cycle breeding.
