土壤肥力是土壤的物理、化学、生物等性质的综合反映,对于植物的生长来说,它包括营养因素和环境因素两个方面。土壤的化学性质,不仅在土壤肥的营养因素方面起着重要作用,而且对于土壤肥力的环境因素的很多方面也有影响。因此,尽管对于土壤肥力的实质,可以有各种不同的理解,但是土壤的化学性质在土壤肥力上的意义,却是客观存在。由于这个问题的复杂性,并且也由于我国近十年来在这方面所做的工作很不平衡,所以本文只能就几个较为重要的问题加以讨论。
Soil fertility is a comprehensive reflection of the physical, chemical and biological properties of soil. For the growth of a plant, it includes both nutritional and environmental factors. The chemical properties of soils play an important role not only in the nutritional factors of soil fertility but also in many aspects of environmental factors of soil fertility. Therefore, although there are many different understandings of the essence of soil fertility, the significance of soil chemistry in terms of soil fertility is an objective reality. Due to the complexity of this issue and due to the imbalance in our work in this area over the past decade, this article can only discuss a few of the more important issues.
