摘要
农业矿物按其在大农业中的用途可分为9个类,再依其功能分为17个亚类。现今已开发利用的农业矿物有近40多种。农业矿物能利用的不仅是其矿物组成和比学成分,而且还包括其物理和化学性质。开发利用农业矿物对农业有提高产量、防治病虫害、改良土壤、降低成本、保护生态环境等等功效,从而促进大农业生产的发展。
Agricultural minerals can be divided into 6 types and 17 subtypesaccording to their roles and functions in general agriculture. At present,about 40 agricultural minerals have been utilized not only with regard totheir composition, but also with their physical and chemical properties.The further utilization of agricultural minerals is certainly beneficial inpromoting the development of general agriculture, i. e., increasing cropoutput, preventing and curing pest infestations, improving soil, decreasingcosts, and protecting the environment.
