Abstract:

Soil acidification not only causes aluminum toxicity to crops, deterioration of soil structure, decline of nutrient availability and biodiversity, resulting in a significant reduction in crop yield or even no harvest, but also activates heavy metals, causing quality and safety problems of agricultural products, which seriously threatens food security, ecological environment security and sustainable development of agriculture, especially in southern China. It is more common and urgent to carry out large-scale effective governance. Taking Zhejiang Province as an example, which is one of the typical agricultural modernization provinces in the south of China, this paper discussed the current situation of acidified cultivated land and its possible influencing factors based on the years of acidified cultivated land management in Zhejiang Province. The strategy and technical path of acidified cultivated land management were put forward from the technical level and the working level. The application examples and effects of acidified cultivated land management were discussed from paddy field, dry land, orchard land, tea garden land and other types. The existing problems of acidified cultivated land management at the present stage were analyzed. The corresponding suggestions and prospects were put forward, such as expanding the coverage of acidified cultivated land management, integrating the efficient technical model of the base, and increasing the degree of attention. It provides a reference for the management of acidified cultivated land in China.
