提高土壤肥力的目的主要在于充分发挥土壤潜在能力,保证农作物的高额稳产。为了达到这个目的,必须定向控制土壤的变化,改善土壤状况。土壤肥力是各种土壤性质的综合表现,并随着环境和时间而不断变化。要彻底了解土壤肥力,不仅要明悉土壤供应肥、水的容量和供应的快慢及持续时间,还要考虑肥、水的协调和植物根系的生活条件,这就是我们所称的肥力基础(简称肥基)。从本质上看,土壤肥力的高低在很大程度上取决于土壤结构的性态(简称土壤结构 The main purpose of improving soil fertility is to give full play to the potential of soil to ensure high crop yield stable. In order to achieve this goal, it is necessary to control the change of the soil and improve the soil condition. Soil fertility is a composite of various soil properties and varies with the environment and time. To fully understand the soil fertility, we must not only understand the soil fertilizer, water capacity and supply speed and duration, but also to consider the coordination of fertilizer and water and living conditions of plant roots, which is what we call fertility foundation Fat base). In essence, the level of soil fertility depends largely on the state of soil structure (referred to as soil structure
