【Summary Description】 The necessity of environmentally friendly planting techniques lies in their ability to protect the ecological environment, improve the quality and safety of agricultural products, promote sustainable agricultural development, meet the challenges of climate change, and enhance public environmental awareness.

　　I. Protecting the Ecological Environment

　　Environmentally friendly planting techniques follow the principles of ecological balance, using scientific and reasonable planting methods to reduce negative environmental impacts. This technology helps maintain soil health, protect water resources, reduce air pollution, and thus maintain the stability and diversity of the ecosystem. Specifically:

　　Soil Protection: Environmentally friendly planting techniques emphasize soil conservation, avoiding excessive tillage and overuse of chemical fertilizers and pesticides, helping to prevent soil erosion, salinization, and pollution, maintaining soil fertility and biodiversity.

　　Water Resource Protection: Through water-saving irrigation, rainwater harvesting, and recycling technologies, environmentally friendly planting techniques can reduce reliance on groundwater, lower water consumption, and prevent water pollution.

　　Air Protection: Environmentally friendly planting techniques help reduce greenhouse gas emissions, such as through reasonable crop layout and crop rotation and fallow systems, improving soil carbon sequestration capacity and absorbing atmospheric carbon dioxide. In addition, reducing the use of chemical fertilizers and pesticides can also reduce the pollution of agricultural production on the atmosphere.

　　II. Improving the Quality and Safety of Agricultural Products

　　Environmentally friendly planting techniques focus on the quality and safety of agricultural products. By adopting biological control, physical control, and other green control measures, they reduce the use of chemical pesticides, lower pesticide residues in agricultural products, and improve the quality and safety of agricultural products. This not only helps protect consumer health but also enhances the market competitiveness of agricultural products.

　　III. Promoting Sustainable Agricultural Development

　　Environmentally friendly planting techniques are an important support for sustainable agricultural development. It emphasizes the conservation and efficient use of resources, improving agricultural production efficiency, reducing production costs, and achieving long-term stable development of agriculture. At the same time, environmentally friendly planting techniques also help promote the optimization and upgrading of agricultural industrial structure and promote the coordinated development of agriculture and the ecological environment.

　　IV. Addressing Climate Change Challenges

　　With the intensification of global climate change, agricultural production faces unprecedented challenges. Environmentally friendly planting techniques, by improving crop resistance and reducing greenhouse gas emissions, help to cope with the impact of climate change on agricultural production. In addition, environmentally friendly planting techniques can also promote the development of agricultural carbon sequestration, contributing to the mitigation of global warming.

　　V. Enhancing Public Environmental Awareness

　　The promotion and application of environmentally friendly planting techniques can help enhance public environmental awareness. Through popularizing knowledge of environmentally friendly planting and carrying out environmental education activities, it guides the public to pay attention to the impact of agricultural production on the ecological environment and enhances the public's sense of environmental responsibility and participation.

　　The necessity of environmentally friendly planting techniques lies in their ability to protect the ecological environment, improve the quality and safety of agricultural products, promote sustainable agricultural development, address climate change challenges, and enhance public environmental awareness. Therefore, we should actively promote and apply environmentally friendly planting techniques to contribute to building an ecological civilization and promoting green development in agriculture.
