Pollution-free tea means that under the conditions of good production environment, the content of harmful substances such as heavy metals and pesticide residues in tea is controlled within permissible limits, which is the general term for non-pollution and safe tea. Pollution-free tea is good because of its good quality and marketability. There are more than 50,000 acres of mountain tea gardens in our city. The natural growth environment is better, and pollution-free tea should be produced. The main cultivation and management techniques for producing pollution-free tea are described as follows:
First, soil improvement
1. Between the young tea plantation and the tea plantation that reforms the tea plantation, legume green manure should be cultivated, and the soil should be deeply buried and fertilized.
2. Laying the grass between tea trees will help preserve soil moisture, stabilize soil temperature, reduce weeds, and increase soil biological activity. Coverage includes weeds, pruning foliage, bark wood chips, and straw.
3. It is forbidden to use harmful municipal waste and sludge in tea plantations.
Second, tea garden fertilization
1. Basal fertilizer: In mid-October to mid-November each year, deep-growing organic fertilizers between rows and covering the soil should be sooner rather than later. Each mu of cooked farmyard fertilizer 1000-1500 kg, or commodity organic fertilizer 100-150 kg.
2. Top dressing: In the production season, the average tea garden uses 80-100 kg of fertilizer per acre, which is divided into 2 to 3 applications. Organic tea gardens use rotten organic liquid fertilizers to root or use commodity organic fertilizer 100-150 kilograms per mu, divided into 2 to 3 times.
3. Foliar fertilizer: It is an effective way to supplement nutrition and accelerate the growth of tea. It is generally better to use foliar fertilizers containing amino acid nutrients, and it is forbidden to use hormonal foliar fertilizers. After spraying foliar fertilizers for ten days, it can be used to collect tea.
Third, controlling and controlling the occurrence of pests and weeds
1. Agricultural control: (1) Choose tea seed varieties with strong resistance to pests and diseases in accordance with local conditions. 2 Strengthen manure management, increase tree vigor, and increase tea plant resistance. 3 Take agricultural measures such as pruning, plowing, and picking to directly control and control.
2. Biological control: Use natural enemies (parasites, predatory birds, spiders, etc.) and biological pesticides (animal sources, plant sources, and microbial pesticides) to control pests and diseases.
3, physical control: the use of a variety of physical factors (light, heat, etc.) artificial or apparatus to prevent pests, such as artificial killing, light trapping and so on.
4. Chemical control: For tea gardens with serious pests and diseases, chemical pesticides with low toxicity and low residual content can be used to eliminate pests and diseases. However, the concentration, time, and method must be mastered at the same time. At the same time, pesticide safety intervals must be strictly enforced. Organic tea gardens and AA grade tea gardens are banned from chemical pesticides.
5, weed control: weed control in order to achieve the balance between the balance with the tea tree, do not have to take all the cleanliness. Roots and stems of perennial weeds are completely removed; seeds are spread to eradicate weeds before and after weeding; farmyard manure is used for composting; and organic matter, films, and nets can also be used to suppress weed initiation.
Fourth, reasonable tea tree pruning and adoption: 1 normal production of tea gardens generally after the end of spring tea line light pruning or deep pruning, banned three years two Taiwan gongs; on the yield is not high, tree decline in the tea plantation can be heavy pruning or Taiwan Oh, and apply basal fertilizer. 2 Maintain a gap of about 20cm between tea rows to facilitate ventilation and light transmission, and reduce pests and diseases; 3 Care must be taken in the tea garden after pruning.
