Abstract:

The purpose of this study is to solve the contradiction between the application intensity and utilization efficiency of chemical fertilizers in the agricultural development of Xishuangbanna, Yunnan, and to help the green transformation of agriculture. By analyzing the current situation of chemical fertilizer application in Xishuangbanna tropical region (including Jinghong City, Mengla County and Menghai County), the problems of blind fertilization and weak supervision were revealed. The article proposed countermeasures such as promoting soil testing and formula-based fertilization, constructing a low-carbon ecological tropical region, establishing a standardized fertilizer application evaluation system, and strengthening technical training and promotion of fertilizer application. The study emphasized the construction of a three-in-one precise regulation system of “environmental carrying- crop demand- nutrient cycle”, which provides a reference for the region to achieve fertilizer reduction and efficiency, promote sustainable agricultural development and rural revitalization strategies, and provide reference for agricultural green transformation in other tropical regions.

Key words: Xishuangbanna, tropical regions, fertilizer, present situation, countermeasures
