Green manure is a clean organic fertilizer free from heavy metals, antibiotics, hormones, and other residues. It is also an effective measure to reduce the application of chemical fertilizers and improve soil fertility. Intercropping winter green manure in tea gardens is an effective way to maintain and improve soil fertility, utilizing garden resources to nourish the garden and trees. This practice can maximize resource utilization, as green manure covering the soil surface reduces soil erosion by rainwater, absorbs and activates soil nutrients, and prevents nutrient loss. Since there is less competition between winter green manure and tea plants, it has good prospects for wider application in tea gardens. Based on years of experimental research, this article introduces suitable varieties of winter green manure for tea gardens and key points in their cultivation techniques. Suitable Varieties of Winter Green Manure for Tea Gardens and Their Characteristics Tea garden soils are typically acidic and rich in aluminum, so the green manure crops grown must be acid and aluminum tolerant. The main criteria for selecting suitable green manure crops are biomass yield and quality, which are important indicators of a variety's stress tolerance and productivity. Nitrogen content is one of the most critical…
