关于我国农业需求化肥品种几个问题的探讨

化肥在提高作物产量和改善农产品品质方面的作用已广为人知,但不同品种的化肥有不同的施用特点和效果。笔者从资源需求、消费习惯和生产条件等不同方面对当前农业所需要化肥品种的有关问题进行了综合分析,指出不能笼统地认为我国化肥复合率低于发达国家,应对氮磷钾肥料品种分别作具体分析;充分考虑地域特征和多元化的生产和消费体系对肥料所提出的不同需求,发展多种类型的化肥品种;有针对性地发展缓/控释肥和硝态氮肥。最后提出,针对我国农业需要,应加大化肥新品种的开发和加强农化服务工作。

Inquiry into Some Problems on Chemical Fertilizer Products Needed in Domestic Agriculture

The role of chemical fertilizers is well known in the increase in crop yield and the improvement on the quality of agricultural products,but different chemical fertilizer products have different application characteristics and results.The writers make a comprehensive analysis of some problems relevant to chemical fertilizer products needed in agriculture and generally concerned by people at present in terms of demand for resources,consumption custom,and production conditions,and point out that it is inappropriate to regard generally that the percentage of compound fertilizers is lower than that in developed nations but a concrete analysis is to be mede of nitrogenous,phosphatic and potassic fertilizer products;different demands for fertilizers are to be fully considered with respect to regional characteristics and the multivariant production and consumption system,and multiple types of chemical fertilizers products are to be developed,and slow-or controlled-release fertilizers and nitrate nitrogenous fertilizers are to be developed to suit various purposes.The writers finally propose that in connection with domestic agricultural needs the development of new chemical fertilizer products is to be enhanced and work on agronomical service strengthened.
