Soil acidification, accumulation of aluminum toxicity, weed competition and insect pests have seriously restricted the sustainable and high-quality development of red and yellow soil old tea plantations in southern China. By using Phosphate-soliloquizing nitrogen-fixing bacteria and soil remediation substrates, combined with the tea garden management technology of grass control and grass insect control between functional grass species and tea trees, a new technology system for green regulation of high-quality tea garden soil and fertilizer is established, which is expected to solve the production problems of elderly tea gardens due to soil acidification, soil production capacity decline and long-term dependence on chemical fertilizers. It will effectively improve the soil environment of tea gardens, increase soil nutrient content, improve microflora, improve the quality, yield and market competitiveness of tea on the basis of reducing the application of chemical fertilizers and increasing efficiency, and promote the tea industry to enter high-quality, sustainable and healthy development.
