Description

Technical Field

[0001] The present invention belongs to the field of green ecological agriculture, and specifically relates to a low-carbon planting and breeding combined ecological greenhouse. Background Art

[0002] Planting greenhouses can increase the supply of agricultural products and meet market demand. Traditional agricultural production is often restricted by weather and geographical conditions, with uncertain output and difficulty in meeting large-scale market demand. The use of breeding greenhouses means that the production of agricultural products is no longer restricted by seasons and geographical environments. Temperature, humidity, light and other factors in the greenhouse can be effectively controlled, and the growth cycle of crops and poultry livestock can be shortened, greatly increasing output. Planting greenhouses are widely applicable and can be used to grow all kinds of agricultural products such as vegetables and fruits, and can also be used for poultry farming. Through planting greenhouses, the supply of agricultural products can be more stable and the prices in the market will be more reasonable, thereby promoting the healthy development of the social economy.

[0003] However, traditional greenhouses require external energy and nutrients, and the straw and other planting fertilizers produced are difficult to reuse. Summary of the invention

[0004] The purpose of the present invention is to reduce the energy consumption in the planting and breeding process of traditional planting greenhouses and to provide a low-carbon planting and breeding combined ecological greenhouse.

[0005] The low-carbon planting and breeding combined ecological greenhouse of the present invention comprises a planting area, a water channel, a (low-carbon) light and water water evaporation module, a non-powered cooling film module, a condensation heat storage module and a breeding area. A water channel is arranged in the ecological greenhouse, and the planting area and the breeding area are arranged on both sides of the water channel. At least one non-powered cooling film module is arranged on the roof of the ecological greenhouse. The non-powered cooling film module is a non-powered cooling film. A condensation water droplet recovery device is arranged at the bottom of the non-powered cooling film module. The condensation water droplet recovery device is connected to the water inlet of the heat transfer pipe in the condensation heat storage module. The condensation heat storage module is a heat exchanger.

[0006] A support frame is installed above the canal, and a photothermal water evaporation module is laid on the support frame. The photothermal water evaporation module is a water-absorbing hydrophilic material with a photothermal conversion (conversion) coating, and the lower part of the water-absorbing hydrophilic material is immersed in the water in the canal.

[0007] The present invention provides a low-carbon ecological greenhouse combining farming and breeding. The ecological greenhouse combining farming and breeding can use straw produced by planting to supply food needed by livestock and poultry. The breeding area can provide nutrients for the planting area. The smart water channel can supply water to the breeding and planting areas. The photothermal conversion module, the non-powered cooling membrane module and the condensation heat storage module can use solar energy to provide energy. The greenhouse can realize energy storage and energy utilization by utilizing solar energy. The total output of breeding and planting can be increased by 150%, and the energy consumption of planting and breeding can be reduced by more than 40%. It has broad application prospects.
