中文摘要

Taiwan is a subtropical-tropical island characterized by high temperature and heavy rainfall. Intensive agricultural practices have served as a strong foundation for Taiwan's commercial and industrial economic miracle. In recent years, chemical pesticides and fertilizers were extensively applied to obtain higher crop yield. Overusing agrochemicals led to several agricultural problems such as poor cropping system. The excessive application of chemical nitrogen fertilizer accelerated soil acidification and threatened air and groundwater contamination at the same time. Using organic fertilizers and bio-fertilizers offer a safe option for reducing the agrochemical inputs. Over the years, bio-fertilizers have been developed in several laboratories in Taiwan. Beneficial microbes such as rhizobium, associative and free living nitrogen-fixing bacteria, phosphate-solubilizing bacteria (PSBs), arbuscular-mycorrhiza (AM), fungi, organic materials, and decomposing microorganisms are considered as bio-fertilizers. These are continuously isolated from various ecosystems, and their performances and field conditions are assessed in the laboratories. The extensive research program on beneficial bacteria and fungi has resulted in the development of a wide range of bio-fertilizers, which satisfied the nutrient requirements of crops and increased the crop yield as well. Many experiments in greenhouses and in field conditions have revealed that different crops responded positively to microbial inoculations. In particular, successful rhizobial inoculants were applied to leguminous plants and AM fungi for muskmelons in order to increase the yield and quality. Multifunctional bio-fertilizers were developed to reduce about 1/3-1/2 of chemical fertilizer application. In the future, enhancement and maintenance of soil fertility through microorganisms will be a very significant concern. Long-term conservation of the soil's health is the key benefit of bio-fertilizers, which is vital in sustainable agriculture.
