变废为宝:建立高效性大农业体系自然资源包括非再生性的矿产资源和再生性的生物资源。农业生产的实质是通过再生性的生物资源——植物的光合机制把太阳能转化为化学能,把无机物转化为有机物。在长期的生产实践中,人们对资源的认识在不断加深,资源的多用性(即多次性利用)是人类认识史上的飞跃,为我们合理开发利 Turning waste into treasure: Establishing an efficient large-scale agricultural system Natural resources include non-renewable mineral resources and regenerative biological resources. The essence of agricultural production is the conversion of solar energy into chemical energy and the conversion of inorganic matter to organic matter through the photosynthetic mechanism of plants, a renewable biological resource. In the long-term production practice, people’s understanding of resources is deepening, and the multi-use of resources (ie, multiple utilization) is a leap in the history of human cognition, which helps us rationalize development
