The Restriction of Land IndexWith the implementation of rural revitalization and urban-rural integration, the scarcity of rural land resources and the red line of policy in some rural areas, especially in some economically developed areas such as southern Jiangsu, have increasingly become the bottleneck and restriction in the development of rural modernization and the integration of primary, secondary and tertiary industries.The Imagination of Multiplying the YieldThe latest modern agriculture, which is represented by the intelligent agriculture and three-dimensional plant factory, can help us get rid of the constraints and restrictions, providing a broader world for the development of rural modernization. The beginning of the research on plant factory in China was not late, and the industry began to boost in recent two years. According to the preliminary research, Jiangsu has also built plant factories of different sizes in Nanjing, Suzhou, Suqian, Lianshui County, Hongze District and so on.Realize Food Security through Output Index Instead of Land IndexWhen the revolution of modern agricultural production mode can bring about the output and revenue growth of agricultural products per unit area by tens or even hundreds of times, it is possible to guarantee China's food security with a new idea, and the “safety red line” of land policy, which aims at ensuring the quantity of cultivated land, may be broken through.
