磷是构成植物细胞和保证植物正常生长发育的重要元素。土壤磷素丰缺对农业生产具有显著影响。在1979年至1984年,我们对各地耕种土壤自然土壤的磷素进行了全面测定,对全省各种类型土壤的磷素组成和积累转化进行了试验研究取得土壤磷素数据约30余万个。本文在对上述数据资料进行初步分析的基础上,就我省土壤磷素状况及其人为调控进行探讨。
Phosphorus is an important element that makes up plant cells and ensures the normal growth and development of plants. Soil phosphorus abundance has a significant impact on agricultural production. From 1979 to 1984, we conducted a comprehensive determination of phosphorus in natural soils cultivated in various places throughout the province. We conducted a pilot study on the phosphorus composition and accumulation and transformation of various types of soils in the province and obtained about 300,000 soil phosphorus data . Based on the preliminary analysis of the above data, this paper discusses the status of soil phosphorus and its human regulation in our province.
