Planting Non-pollution Tea Five Essentials

In recent years, the international trade market has raised the quality requirements of China's tea, and solving pesticide residues is an urgent issue. To produce pollution-free tea and ensure a high-quality organic food supply market, we must adopt the following five technical measures to sum up: 1. Strengthen management of tea gardens (1) Advocate the use of organic fertilizers in tea gardens. The base fertilizer is applied once in winter and the pre-germination fertilizer is applied before the spring tea. The relay fertilizer is applied once after the spring tea to prevent the tea tree from being undernutrition and affecting the quality of summer and autumn tea. (2) Emphasizing timely tillage and weed removal in order to loosen the soil, clean the tea garden, promote aerobic bacteria-microbiological activities, decompose humus content, help tea trees absorb effective nutrients, promote robust growth of tea trees, enhance tea stress resistance, and effectively prevent plants The occurrence of pests and diseases. (3) Take advantage of the rich natural conditions of firewood on the edge of the tea area. A softer firewood was harvested before the spring tea, covered in tea bushes or between tea rows, which can prevent weed growth and reduce evaporation of water in the soil, and prevent autumn drought. After the grass rots, it will improve the structure of soil pellets and increase the fertility of the tea garden. 2. No pests are sprayed on pesticides, and the protection of natural enemies, beneficial insects, is promoted to achieve insects. In the tea area research, tea farmers have reflected that spraying pesticides is good or bad, beneficial insects kill together, and the benefits are not satisfactory. What is worrying is that there are different levels of pesticide residues in the refined tea. This should be given great attention. 3. The application of chemical fertilizers has a strict management system in more scientifically developed countries, as more fertilizers will result in soil compaction and damage to the soil aggregate structure. This will affect the normal growth and development of tea trees to a certain extent, and the quality of tea will be inferior. Farmers wishing to replant fertilizers should apply farm organic fertilizers to ensure the quality of organic teas. 4. Optimize the ecological environment. Around the tea plantation, we should pay attention to the protection of the ecological environment. In particular, we must protect windbreak forest belts, beneficial birds and animals in the forests in the northwest of the alpine tea garden, and create a good environment for tea production from different angles. 5. Strictly follow the technical specifications of different teas for picking and manufacturing. In particular, the machinery and equipment of the early and refined factories, as well as the places where the raw materials such as green leaves are piled up, must be clean and sanitary to prevent re-contamination of the manufactured products, so that the finished organic tea can meet the standards of color, smell, and taste, and it can be widely used.
