土壤是人类生产和生活最基本、最重要的自然资源,是农业可持续发展的基础。但在对土壤资源的利用过程中,一些不合理的现象导致了土壤质量的退化,带来了一系列问题。其中,不合理施肥是一个重要因素。而在我国,由于人口压力大、不合理开发等原因,这些问题更为严峻,必须通过实施测土配方施肥、提高肥料利用率加以解决。而缓控释肥由于具有利用率高、施用简便、更符合作物需要等优点,必将成为测土配方施肥的有效施肥载体。 Soil is the most basic and important natural resource for human production and life, which is the basis for the sustainable development of agriculture. However, during the utilization of soil resources, some unreasonable phenomena led to the degradation of soil quality, which brought a series of problems. Among them, irrational fertilization is an important factor. However, in our country, these problems are more serious due to the huge population pressure and unreasonable development. Therefore, we must solve the problem by implementing soil testing and formula fertilization and increasing fertilizer utilization. The controlled release fertilizer due to its high utilization, easy application, more in line with the needs of crops, etc., will become the effective soil fertilization fertilization carrier.
