With the increase in output and the improvement of tea quality, sales have risen accordingly, and the income of tea gardens has become more stable. This planting pattern has a positive impact on the surrounding areas. More tea picking requires more labor input, creating a large number of employment opportunities for the local area (Zhao et al., 2022; Wang et al., 2024). This successful practice provides a referential model for other tea gardens. Through innovative planting and management methods, more high-quality tea can be produced and long-term development can be achieved (Zhao et al., 2022; Wang et al., 2024). 8 Prospects and Suggestions 8.1 Research on the regional adaptability of high-density tea planting High-density tea planting can increase the tea yield and make better use of the land, which is its major advantage. However, whether this planting method can succeed everywhere depends on whether it can adapt to the environment of different places. Therefore, comprehensive research needs to be conducted in many different regions. The research focus should be on observing whether high-density tea planting is effective under different weather and soil conditions, as these factors have a significant impact on how the tea grows and how much can be harvested. Just as the research conducted in Yingde, Guangdong Province, stated, the local weather and soil determine whether it is suitable for growing tea. Such research results can also provide references for planning high-density tea cultivation in other places (Chen et al., 2022). In addition, understanding the influence of altitude and terrain slope on the growth of tea can better arrange the planting location of tea trees and harvest more tea (Jayasinghe and Kumar, 2019; Chen et al., 2022). In future research, the relationship between high-density tea planting and the local ecology will continue to be deeply examined. The expansion of tea gardens may affect the local ecology and have an impact on water sources, soil and the survival of animals and plants. The focus of the research is to strike a balance between increasing tea production and protecting the ecological environment. We should not damage the environment just to produce more tea. This requires clarifying the benefits and drawbacks of tea cultivation for the ecology and how to promote each other, just like the research conducted in a major tea-producing area such as Anxi County (Bao et al., 2024; Deng and Chen, 2024). 8.2 Agricultural policies and promotion strategies for high-density tea cultivation To promote high-density tea cultivation, agricultural policies should be formulated to encourage sustainable planting methods and provide certain support to farmers. Policy makers can refer to those land use policies that have successfully coordinated the expansion of tea planting with ecological sustainable development, such as the policy implemented in Anji County, China. This policy comprehensively considers natural environment and socio-economic factors to guide tea planting planning (Zhang et al., 2017). Policies should also vigorously promote agricultural technologies that adapt to climate change, such as the use of controlled-release fertilizers and the addition of biochar, thereby reducing the emission of nitrous oxide in tea garden soil and lowering the negative impact on the environment (Wang et al., 2020). To promote high-density tea cultivation, the key is to make tea farmers understand the benefits of such cultivation and also teach them the specific planting methods. The successful planting experiences and the latest research results of others can be presented to everyone through holding training courses and exchange meetings. In addition, the government can offer subsidies to tea farmers or provide financial assistance. In this way, when they switch to high-density tea cultivation, they will have to spend less money on purchasing tea seedlings and purchasing equipment at the beginning. As long as the government’s supportive policies and scientific research are well coordinated, high-density tea planting can be promoted in more places, the efficiency of tea planting can be improved, and long-term development can also be achieved. 8.3 Strengthen the mechanization of tea gardens and ecological protection technologies To improve the method of high-density tea planting, it is necessary to use more machines for work and apply ecological protection technologies. Only in this way can the tea be grown quickly and well and achieve long-term
