在《微生物学》教学中补充生物有机肥部分的内容设计

Designing of Adding Content of Bio-organic Fertilizer into Microbiology

目前,由于化肥的大量使用,引起了一系列生态、环境问题,例如土壤环境受破坏、农产品质量下降、环境污染、资源浪费等。生物有机肥是由功能微生物与经无害化处理、腐熟的有机物料复合而成的一类兼具微生物肥料和有机肥效应的肥料,具有无毒、无害、无污染的特点,可以有效促进植物生长,已成为未来农业可持续发展的迫切要求。然而,大学《微生物学》教材中缺少生物有机肥教学内容。为满足社会和学生对这方面知识的渴求,设计了生物有机肥教学内容予以补充,主要讲授化肥大量使用带来的生态、环境、资源等问题;生物有机肥的发展概况、特点、作用和肥效机制;颗粒型生物有机肥生产工艺介绍。并对生物有机肥今后的发展方向作了展望。

At present,the heavy use of fertilizers has caused a series of ecological and environmental issues such as soil destruction,declination in the quality of agricultural products,environmental pollution and waste of resources. Bio-organic fertilizer is a compound of functional micro-organisms and organic material unharmfully processed and digested,combining both microbial fertilizer and 0organic fertilizer effect. Bio-organic fertilizer has characteristic of non-toxic,harmless,pollution-free,and can effectively promotes the growth of plant,and become an urgent requirement for sustainable development of agriculture. But there was no bio-organic fertilizer teaching content in the textbook of Microbiology. In order to meet the requirement of the society and students,the bio-organic fertilizer teaching content was designed to fill up the vacancy. The meaning of biological organic fertilizer was introduced and the following issues was discussed：the serious ecological,environmental and resources issues caused by extensive use of fertilizers; overview of organic fertilizer,including its characteristics,effect and fertilizer mechanism; initiatory introduction of manufacture technology of granular-pattern bio-organic fertilizer. Meanwhile,an outlook on its future development of bio-organic fertilizer was made.
