Description

Technical Field

[0001] The invention relates to a low-carbon agricultural system. Background Art

[0002] How to increase crop yields and develop green agriculture has always been a concern. In order to promote the high-quality development of my country's agriculture, the adoption of energy-saving and low-carbon agricultural production technologies has become an inevitable trend in the development of contemporary agriculture. Agricultural greenhouses are a type of agricultural facility widely used by countries around the world to achieve modern, intensive and efficient production when developing modern agriculture. They have strong risk resistance, good thermal insulation and heat storage effects, and high plant yields. It has become a planting method that is continuously deepened and developed in various countries. Constructing a sustainable planting model for vegetable greenhouses can not only realize agricultural planting activities, but also effectively recycle various waste gases, wastewater and waste generated during the planting process, achieve environmental protection, green and low carbon, and promote the sustainable development of the agricultural economy. In vegetable greenhouses, common waste is vegetable straw and residues. According to statistics, 500m 2 The waste generated by vegetable greenhouses in a year is about 1.2 tons. If waste is piled up everywhere, it will breed bacteria and cause environmental pollution to the surrounding planting areas. Therefore, it is necessary to establish a sustainable vegetable greenhouse planting model that can form a mutually supplying biological chain to meet the development needs of ecological agriculture. The development of low-carbon industries can save energy and reduce emissions, protect the ecology, and continuously improve the utilization rate of resources and energy.

[0003] Develop solar energy resources and seek new impetus for economic development. The heating and heat preservation of greenhouses have always been the key issues that bother farmers. The light and temperature required in the greenhouses are very important for crops, and the consumption of electricity such as lighting in the greenhouses is also very huge. How to improve agricultural greenhouses so that they can not only ensure the light and temperature for crop growth, but also achieve energy conservation is an important issue that affects the future development of agriculture. With the strengthening of the international energy crisis and environmental protection awareness, solar photovoltaic power generation has been widely promoted. Summary of the invention
