一、课题的提出江苏太湖农区是一个人多、地少而农、副产品的自给及商品率又均要求很高的地区,如何进一步提高农副产品的生产水平及商品率,是八十年代乃至今后一个相当长的历史时期所面临的重大课题。就太湖地区来说,种植业与养殖业历来是两个相互依存的部门,而养殖业的结构与发展水平,更直接受制于农田种植业的结构与发展水平。由此,着眼提高农田作物种群的初级生产力,改善作物种群的结构,使之适应并促进养殖业发展的要求,从而提高农田初级生产与次级生产之间的能量转换效率及物质循环的水平,乃是改善农区农
First, the subject of the proposed Taihu Lake in Jiangsu Province is a multi-person, less land and agriculture, by-product of self-sufficiency and high commodity rates are required areas, how to further improve the production level of agricultural and sideline products and commodity rates, is the eighties and even A major issue facing a fairly long historical period in the future. As far as the Taihu Lake region is concerned, farming and aquaculture have always been two interdependent sectors. The structure and development level of aquaculture are more directly controlled by the structure and level of development of the crop farming industry. Therefore, we should focus on improving the primary productivity of farmland crop populations, improving the structure of crop populations, adapting and promoting the requirements of aquaculture development so as to improve the energy conversion efficiency and material circulation between farmland primary production and secondary production, It is to improve farming in rural areas
