Working with machines can save a lot of labor costs and enable tea gardens to earn more money. For example, Australia has invented a machine for cultivating tea seedlings, which can stably cultivate good tea seedlings and has been of great help for large-scale tea planting (Lowe et al., 2022). If some advanced tea-planting, pruning and tea-picking machines are introduced, the working speed in the tea garden can be even faster. Ecological protection technologies cannot be lacking either. Only in this way can high-density tea planting avoid damaging the environment. There is a kind of “agroforestry hybrid” planting method in Indonesia. Some shade-tolerant crops are planted among tea trees, which can not only prevent the land from being wasted but also make the soil more fertile (Maharani et al., 2022). In addition, allowing tea gardens to coexist harmoniously with the surrounding natural environment can also bring many benefits, such as storing more carbon dioxide and providing a better living environment for animals and plants. Anxi County, Fujian Province is a successful example (Bao et al., 2024). The tea garden combines machine operation with ecological protection, using high-density planting methods. This not only enables tea farmers to earn more money but also helps protect the environment. 9 Concluding Remarks The high-density planting model has been proven to significantly increase yields. The principle is to plant more plants in the same area and make full use of resources such as sunlight, water and nutrients. This method has a remarkable effect on the cultivation of fruits such as acid lime. After adopting high-density planting, the fruit yield per unit area is more than twice that of the traditional method. The same is true for corn cultivation. Increasing the planting density can make better use of resources such as light and nitrogen, thereby enhancing the grain harvest. These achievements indicate that high-density planting is also applicable to tea gardens, which can increase tea yields and the efficiency of resource utilization. In the tea planting industry, the method of high-density planting is particularly important. Doing so can not only make more full use of resources such as land and fertilizer, but also enable the tea leaves to grow more and better. Research shows that as long as the number of tea trees planted is well controlled and less chemical fertilizers and pesticides are used, not only can the damage to the environment be reduced, but also the soil can be made more fertile, which is indispensable for the continuous growth of good tea. By relying on high-density planting, tea gardens can harvest more high-quality tea leaves, earn more money and ensure the long-term development of the entire tea industry. High-density planting in commercial tea gardens will have better development in the future, but there are still many areas that can be improved in terms of technology and management. Combining high-density planting with new fertilization methods, such as the simultaneous use of farmyard manure and chemical fertilizers, can not only increase the yield and quality of tea, but also reduce environmental pollution. In addition, by cultivating tea tree varieties suitable for dense planting and rationally adjusting the planting density of tea trees with precise planting techniques, resources can be utilized more fully, laying a foundation for establishing an efficient and environmentally friendly tea tree planting model. These new development directions may bring about significant changes to the tea industry, achieving the dual goals of increased production and environmental protection.
