本文是我所1950-1985年在中国磷矿农业利用方面主要研究结果的简要综述。文中对有关的重要结果作了较详的介绍,包括:1.土壤性质对磷矿粉肥效的影响;2.植物对磷矿粉的吸收能力;3.磷灰石的结晶性质与磷矿粉肥效的关系;4.磷矿粉的合理施用技术。从农业生产目前对磷肥的迫切需求和磷肥工业的现状与发展的可能看,将一部分在工业上不能利用的磷矿,在酸性士壤上因地制宜地对某些吸磷能力较强的植物,如豆科作物、豆科绿肥、经济林木、一般的造林和营林、人工牧草等植物上直接施用,仍有一定的现实意义。
This article is a brief summary of the main research results of our country’s use of phosphate rock in 1950-1985. In this paper, the important results are described in detail, including: 1. The effect of soil properties on the efficiency of phosphate rock; 2. Absorption capacity of plant on phosphate rock; 3. The crystalline nature of apatite and the effect of phosphate rock powder Fertilizer effect; 4. Rational application of phosphate rock technology. From the current urgent need of agricultural production of phosphate fertilizer and the status quo and development of the phosphate fertilizer industry, it is probable that a part of phosphate rock that can not be used industrially in some acidic soils is suitable for some plants that have high phosphorus uptake capacity, such as Leguminous crops, leguminous green manure, economic forest, general afforestation and forest, artificial grass and other plants directly applied, there is still some practical significance.
