Tea green production mode and supporting integration technology
(1) Establish pest and disease monitoring points. One or two tea tree pest and disease monitoring points will be established in each demonstration area, and one person with professional foundation will be assigned to monitor the work, and the pest information will be uploaded through the WeChat platform in a timely manner, and the experts will remotely diagnose. Set up the indicator light, yellow plate, and sex attractant as predictive forecasting tools. Recommended configuration standard: install one test light; suspend 50 yellow plates at a density of 45 meters (hang before the main pests such as small green leafhopper and black-winged whitefly); install tea ruler (tea caterpillar) adults at a density of 510 meters 20 sets of sexual attractants.
(2) Establish a green tea production counter for tea gardens. The project demonstration county (township) selects the agricultural resources dealers with professional qualifications, approval of green production, unified identification and unified image to set up the “Huiderong†tea garden green production agricultural materials counter. All products of the counter must be screened and tested by the technical service platform. After the examination is passed, the base of the demonstration area will be supplied at a uniform price to ensure product quality.
(3) The chemical pesticides in tea gardens replace the “drug reduction†technology. Accelerate the ecological control of pests and diseases, based on the monitoring of tea garden pests and diseases, premise the agricultural control measures such as picking, pruning and protecting the beneficial activities of tea gardens, using green insect control, insect swatches, sexual attractants, predatory cockroaches and other green prevention and control measures. Based on the advanced application techniques such as low-volume spray and electrostatic spray to improve the target of spray, the demonstration and promotion of plant-derived pesticides, mineral-derived pesticides and microbial-source pesticides are used to replace chemical pesticides. Promote the integration of specialized and unified defense and green prevention and control, and coordinate the promotion of the three elements of “medicine, machinery and peopleâ€, focusing on new agricultural management entities and specialized service organizations for pest control, and training a group of scientific drug technology backbones to ensure tea. Quality and safety, driving large-area applications.
(4) Tea plantation fertilizer reduction and synergy (scientific fertilization) technology. Strengthen the detection and diagnosis of pH value, organic matter, biological activity, phosphorus and potassium, medium and trace elements, heavy metals and rare earth in tea gardens in demonstration areas. Demonstration of soil testing and formula fertilization, water and fertilizer integration, tea garden machinery ploughing and ditching and other techniques to reduce the amount of efficiency, support farmers to use livestock manure and local forest and grass resources, build farm organic fertilizer, choose commercial organic fertilizer, cake fertilizer. According to local conditions, planting green tea in green tea, improving soil organic matter, applying soil conditioner, tea gardening and soil acidification and other soil remediation technologies, researching and developing integrated high-yield, high-efficiency and ecological fertilization technology models. Actively explore the effective mode of government procurement services, support the development of specialized and social service organizations, and use modern information technology to accelerate the promotion and application of scientific fertilization technology.
(5) Tea garden ecological optimization technology. Strengthen the construction of tea garden infrastructure, and gradually improve the supporting construction of tea garden roads, ditches, surrounding ecology, and tea and travel. Strengthen the application of tea intercropping mode, planting sweet-scented osmanthus, ginkgo and other trees in the free space between tea garden roads, branch roads and plots. Plant trees are planted around the tea plantation as shelter forests, terraced tea gardens are planted on the ladder wall, and young tea gardens are planted. Green manure or grass cover, constantly optimize and enhance the ecological biodiversity of tea gardens.
