2019-11-01 15:04:20
Organic tea is a kind of fresh leaf produced in accordance with the organic agricultural production system and method in the production areas without any pollution. It is not contaminated by chemicals, etc. during processing, packaging, storage, transportation and sales, and has been awarded by the organic food certification organization. Certificate of tea. Organic tea is a truly natural, high-grade, high-quality health drink that represents the development trend of tea production in the future and has great potential for development. The relevant technology is introduced as follows.
Environmental selection area should be far away from cities and industrial areas. The air conforms to the national first-class standard for atmospheric environment quality. The quality of irrigation water conforms to the national standard for surface water environment quality. The content of heavy metals such as copper, lead, cadmium, arsenic, mercury, and chromium in soil must be lower than the national organic tea processing technical regulations. standard. The production, processing, and storage sites should be kept clean and the use of chemicals should be prohibited.
The selection of seed seedlings in the garden must come from the organic agricultural production system and do not use seedlings derived from genetic engineering. The tea plantation garden has good ecological environment, green belts are arranged around it, and organic tea and non-organic agricultural production land should have a certain isolation zone. The garden soil is deep and fertile, with good permeability, with an organic matter content of >1.5%, a pH value of 4.5 to 6.5, effective soil loosening, and strong biological activity. Within 100 meters around the tea plantation, toilets, dung pits, and livestock laps must not be provided.
Soil management 1.1- to 3-year-old tea gardens should be used as green manure between rows to improve the soil. 2. Before the onset of the rainy season and in autumn and winter, basic fertilizers are used to cover the soil with non-pollution straw, shanqing, etc. to reduce the loss of water, soil, and fertilizers, save water and drought in the summer, and protect against freezing in the winter. 3. For the tea gardens with fertile soil, no weeds and high coverage, there should be less (free) tillage. Promote the use of organisms (such as alfalfa, etc.) to improve soil structure and increase soil fertility. 4. Chemical herbicides, synergists, and soil conditioners are strictly prohibited.
Fertilization Technology 1. Tea gardens that produce organic tea are allowed to use organic fertilizers that have not been contaminated by heavy metals, pesticides, and other harmful chemicals, and that have been rendered harmless, certain natural minerals (such as mineral saltpetre, etc.), and natural humates (such as peat, etc.). ) Organic liquid fertilizer produced by pure biotechnology, bacterial fertilizer, organic tea special fertilizer, etc. 2. It is forbidden to apply artificial chemical synthesis of various chemical fertilizers, compound fertilizers, compound fertilizers, rare earth element fertilizers, auxins, artificially synthesized various kinds of multifunctional leaf nourishing liquids, and urban and rural garbage, and industrial waste residues in organic tea gardens. 3. Tea tree branches and leaves trimmed every year must be managed to return the soil. They can be used as fertilizers to be buried directly into the soil, and soil coverings can also be used to cover the rows. 4. Organic tea gardens should be applied base fertilizer and top dressing. The basal manure uses organic fertilizers that have been matured and fully decomposed for 1 to 6 months, including non-polluting fertilizers such as various types of cake fertilizer, green manure, crop residues, peat, and organic tea special fertilizers. Topdressing uses human feces, livestock and poultry manure, organic tea special fertilizers, and bio-organic liquid fertilizers that have been subjected to high-temperature composting and harmless treatment.
