What should be noted when growing pollution-free tea?
How should early spring tea be managed? Please guide the management methods for early spring tea as follows: 1. Weeding and loosening the soil: After 4-5 months of rain and snow, the tea garden soil has become compacted, and some areas have already grown green weeds. At this time, the soil temperature is relatively low. Therefore, weeding and loosening the soil in the tea garden before the spring tea harvest helps to loosen the soil and improve...
What should be noted when growing pollution-free tea? Please explain, thank you.The following issues should be noted when growing pollution-free tea:
1. Strengthen tea garden management
(1) Promote the application of organic fertilizer in tea gardens. Apply a base fertilizer once in winter, a bud-promoting fertilizer once before spring tea, and a relay fertilizer promptly after spring tea, to prevent nutritional deficiency in the tea plants from affecting the quality of summer and autumn tea.
(2) Emphasize timely intertillage and weeding to loosen the soil, clean the tea garden, promote the activity of aerobic bacteria - microorganisms, decompose humus content, help tea plants absorb available nutrients, promote vigorous growth of tea plants, enhance their stress resistance, and effectively prevent the occurrence of plant diseases and insect pests.
(3) Make use of the natural conditions of abundant firewood and grass in the marginal areas of tea regions. Before spring tea, cut one batch of relatively tender firewood and grass and spread it among the tea bushes or between tea rows. This can both avoid the overgrowth of weeds and reduce water evaporation from the soil, helping to prevent autumn drought. After the tender grass decomposes, it further improves the soil aggregate structure and increases the fertility of the tea garden.
2. Do not use pesticides to kill pests. Instead, promote the protection of natural enemies - beneficial insects - to achieve pest control through insects. In surveys in tea regions, tea farmers repeatedly reported that spraying pesticides kills indiscriminately, killing beneficial insects along with the pests, and the results are not ideal enough. What is worrying is that the refined finished tea still contains varying degrees of pesticide residues. This point should be taken very seriously.
3. The application of chemical fertilizers is strictly regulated in countries with more advanced science, because excessive application of chemical fertilizers causes soil compaction and destroys the soil aggregate structure. This to a certain extent affects the normal growth and development of tea plants, and the quality of tea leaves is also inferior as a result. Tea farmers who heavily apply chemical fertilizers are hoped to switch to farmyard organic fertilizers to ensure the improvement of organic tea quality.
4. Optimize the ecological environment. Around the tea garden, attention should be paid to the protection of the ecological environment, especially the windbreak forest belts on the northwest side of high-mountain tea gardens, and the beneficial birds and animals in the forests, so as to create a good environment for tea production from different angles.
5. Strictly follow the technical specifications for different types of tea when picking and processing. In particular, the mechanical equipment in the primary and refining factories, as well as the sites for stacking raw materials such as green leaves, must be clean and sanitary to prevent secondary contamination of factory products, so that the finished organic tea reaches the standards of excellent color, aroma, and taste, and wins praise from consumers for Chinese tea.
