Greenhouse planting ecological system

Abstract

The invention discloses a greenhouse planting ecological system which comprises a greenhouse, a culture pond, a water treatment unit, a vegetable cultivation area and a reservoir are arranged in the greenhouse, a water outlet pipe is mounted at the bottom of the culture pond, the other end of the water outlet pipe is connected with the water treatment unit, the water treatment unit is connected with the vegetable cultivation area, the vegetable cultivation area is connected with the reservoir, and the reservoir is connected with the water treatment unit. The water circulation system is used for circulating water, the water in the culture pond is treated through the water treatment unit, then nutrition blending is carried out, the water is guided into the vegetable cultivation area to cultivate vegetables, and then the water in the vegetable cultivation area is guided into the culture pond to cultivate, so that the resource utilization rate is increased; and the planted vegetables are not in contact with soil, and nutrients are provided by breeding wastewater, so that the effects of environmental protection, health and no pollution are achieved.

Description

technical field [0001] The invention relates to the field of greenhouse planting, in particular to a greenhouse planting ecosystem. Background technique [0002] At present, the existing extensive and intensive aquaculture technologies are highly dependent on water sources. Contaminated water sources will reduce the survival rate of seedlings and increase the risk of breeding, and the discharge of aquaculture wastewater has aggravated the water environment pollution. These discharged sewage It has become an important source of pollution in my country's waters. [0003] When vegetables are planted without soil, most of the nutrients are provided by chemical fertilizers, which will increase the use of chemical fertilizers and cause pollution. Now it is necessary to design an ecosystem that combines aquaculture and vegetable planting to improve resource utilization. Reduce pollution. Contents of the invention [0004] The technical problem to be solved in the present inventi...
