土壤普查是一项建设高产稳产田和实现农业现代化的基础工作,也是科学种田和发展农业生产的一项重要手段。现在已有许多省(市)开展了第二次土壤普查,在发展生产方面取得了一定的效果。但是这次土壤普查多限于土壤养分的诊断,面对于以建设高产稳产农田为中心进行土壤普查则做的不够。实践证明,单纯进行土壤养分的普查诊断,不能全面解决高产稳 Soil census is a basic task of building a high and stable yield farmland and realizing agricultural modernization. It is also an important means of scientific farming and development of agricultural production. At present, many provinces (municipalities) have conducted the second soil survey and have achieved some results in the development of production. However, the current soil census is mostly limited to the diagnosis of soil nutrients. In the face of carrying out soil censuses around the construction of high-yield and stable-yield farmland, the survey is insufficient. Practice has proved that a simple survey of soil nutrient diagnosis, can not fully solve the high yield
