In recent years, the international trade market has raised quality requirements for Chinese Tea, making the resolution of Pesticide residues an urgent issue. To produce pollution-free tea and ensure a supply of high-quality Organic food to the market, the following five technical measures must be taken:
1. Enhance Tea Garden Management
(1) Promote the use of organic fertilizers in tea gardens. Apply a base Fertilizer once in winter, a bud-stimulating fertilizer before Spring Tea, and a relay fertilizer after spring tea to prevent nutritional deficiencies that could affect the quality of summer and autumn teas.
(2) Stress timely hoeing and weeding to loosen the soil, keep the tea garden clean, and promote the activity of aerobic bacteria—microorganisms, which decompose humus content and assist the tea plants in absorbing effective nutrients. This promotes robust growth and enhances the plants' resistance, effectively preventing plant diseases and pests.
(3) Utilize the natural conditions of abundant brush in marginal areas around tea regions. Before spring tea, cut tender brush once and lay it over tea rows or between tea plants. This prevents weed growth, reduces soil moisture evaporation, and has a preventive effect against autumn droughts. As the brush decomposes, it improves soil structure and increases the fertility of tea gardens.
2. Avoid using pesticides to kill pests; instead, advocate the protection of natural enemies—beneficial insects—to achieve pest control through natural means. During field research in tea regions, farmers have reported that spraying pesticides indiscriminately kills both harmful and beneficial insects, and the results are not always satisfactory. More worrying is that finished tea products still contain varying levels of pesticide residues. This point deserves serious attention.
3. In scientifically advanced countries, there are strict regulations on the use of chemical fertilizers because excessive use can lead to soil compaction and the destruction of soil structure. This negatively impacts the normal growth and development of tea plants and diminishes tea quality. Farmers who heavily rely on chemical fertilizers should switch to organic farmyard manure to ensure the quality of organic tea.
4. Optimize the Ecological Environment. Emphasize the protection of the ecological environment around tea gardens, particularly the windbreak forests on the northwest side of mountainous tea gardens and the beneficial birds and animals in forests. Create a favorable environment for tea production from different perspectives.
5. Strictly follow the technical standards for different types of tea during picking and processing. Especially for primary and finishing factories, the machinery and equipment, as well as the areas where raw materials such as fresh leaves are stored, must be clean and hygienic to prevent re-contamination of the final product. This ensures that the finished organic tea meets the highest standards of color, aroma, and taste, earning praise from consumers worldwide.
