With the continuous improvement of living standards, consumers are now placing higher demands on the quality and healthiness of the food they eat. To address these growing concerns, the Beijing Agrotechnical Book Extension Station launched a research initiative focused on the issue of excessive chemical use in vegetable production across the city, which has led to serious pesticide residues and substandard product quality. In response, the station developed a comprehensive study titled "Organic Cultivation Techniques for Vegetables," outlining seven key control points that are essential for successful organic farming:
1. **Base Selection**: The farming area must comply with the "National Organic Food Production Base Examination Regulations" to ensure it meets strict environmental and soil quality standards.
2. **Selection of High-Quality Varieties**: Emphasis is placed on choosing disease-resistant seeds that are not chemically treated or genetically modified, ensuring natural and safe plant growth.
3. **Reasonable Crop Rotation**: Implementing proper crop rotation helps reduce soil-borne pests and diseases, promoting sustainable agricultural practices and maintaining long-term soil fertility.
4. **Cultivating Healthy Plants**: This involves careful nursery management, grafting techniques, timely sowing, appropriate planting, and effective water and nutrient management to support strong and vigorous plant development.
5. **Strengthening Protection Measures**: Using tools like pest control nets and shade nets can significantly reduce the risk of infestations, creating a safer and more environmentally friendly growing environment.
6. **Pest Control**: Whenever possible, physical, agricultural, and biological methods are prioritized for pest management. In cases of severe infestation, bio-pesticides such as Bt (Bacillus thuringiensis) and matrine are used to minimize chemical exposure.
7. **Avoiding Hormonal Contamination**: For certain crops like solanaceous vegetables, the use of hormones and artificial pollination methods is strictly avoided. Instead, natural pollination techniques like bumblebee pollination are encouraged.
The production of organic vegetables plays a crucial role in improving consumer health, restoring soil vitality, and supporting the long-term sustainability of agriculture. By adopting these organic practices, farmers not only meet the evolving needs of the market but also contribute to a healthier and more eco-friendly food system for future generations.
