Abstract: The farmers are the ultimate application persons who change the agricultural science and technology into productivity. The distance training on rural practical technology can increase the efficiency of farmers’ applying the agricultural science and technology. After the Survey of the present situation and effect of distance training on rural practical technology in the south of Fujian Province, the authors narrated the remarkable success of bringing about a great advance in the industry of characteristic agriculture, the industry of no pollution vegetables, the industry of methane technology, and the remarkable success of promoting the construction of new countryside, promoting the transfer of rural labor, promoting the farmers to increase their incomes and become rich by distance training. And the urgent problems which existed in distance training were analyzed. The countermeasures and suggestions of counteracting the distance training’s weaknesses in many ways, conducting distance training of regional characteristic agriculture, conducting distance training according to the farmers’ different educational level and different technology needs, broadening farmers’ outlook, changing farmers’ ideas were put forward.
The developing situation of the modern facility agriculture and corresponding policy measurements of agro-ecological compensation in Tianjin was overviewed. Regarding to the ecological environmental problem in the development of the intensive facility agriculture, learning from EU advanced environmental-friendly technical measures and successful policy management experiences, based on the demonstration and achievement of international cooperative projects between Sino and EU, Sino and Germany, policy suggestions, including to study on the agro-ecological compensation in the facility agriculture; to draw up agro-ecological compensation developing scheme of Tianjin and to set up special subsidy or fund of which, combined with coastal metropolis agro-characteristics, to perfect technical support system of facility agriculture agro-ecological compensation (FAAEC); to establish monitoring and evaluating system on FAAEC of coastal metropolis; to enhance farmers organized level, to promote industrial progress of the facility agriculture, was put forward to provide theoretical and practical reference for the Tianjin government.

The existing biomass technologies mainly focused on producing bio-fuel ethanol by fermenting starch-based biomass, and the large-scale exploration of biomass pyrolysis is still at an experimental stage. However, their applications are limited to low cost-efficiency. The authors’ research group developed a complete set of continuous microwave assisted pyrolysis(MAP) test equipment with a biomass-pyrolyzing capacity of 50-70 kg/h, based on the previous experimental studies on batch MAP of biomass. The self-developed continuous MAP equipment was used to produce bio-oil from untreated corn cob and corn cob pretreated with dilute sulphuric acid. The bio-oil products with different components were obtained. The analysis shows that the compositions of the bio-oil produced from corn cob pretreated with dilute sulphuric acid were relatively simpler and less using Gas Chromatography-Mass Spectrometry (GC-MS). The research results provide theoretical basis and test rig reference for producing bio-oil from agricultural and forestry wastes.
Non-renewable energy sources is declining. The technology of lipase catalyzed synthesis biodiesel has been paid extensive attentions. This paper reviews the research status, technologic feature and industrial application progress of lipase from different bacterial sources in the preparation of biodiesel. Meanwhile, it points out the tendency of the research and development of lipase catalyzed synthesis biodiesel.Lipase-catalyzed preparation provide ideas of biodiesel in future.
For reasons of perfecting standard system, shepherding aquaculture facilities amending standards in the country, achieving the combination of technology innovation and standardization, for meeting the needs of sustainable development of fisheries, according to the research and collecting the information at home and abroad, combing the existing relevant standards about aquaculture facilities and classification discussion, we recomposed the standard system of aquaculture facilities on the base of “Principles and requirements for preparing diagrams of standard system” and “Guideline for the work of complex standardization”. This paper reviews the development of China healthy aquaculture, briefly introduces the current situation of equipment standard for healthy aquaculture, and points out the direction of future development.
