生物多样性及其在农田作物生产中的意义和作用

Significance and Function of Biodiversity in Crop Production of Farmland

从生物多样性这一现代研究课题出发，论述了作物种类多样性，作物与杂草关系的意义。大量资料表明，保持农田耕地作物种类的多样性，保留一定数量的杂草以及选择合适的植物和作物相伴是现代生态农业的一个重要理念，也是现代作物栽培制度的改革和新技术体系建立的理论基础之一。这方面的研究和探索将会对耕地的永续利用和持续农业的发展做出新的贡献。

From biodiversity, species diversity of crop, and the relationship of crops and weeds were discussed. It is a important conception of EcoAgricultural to persist species diversity of crop, keep controlled amount weed and to select a special weeds as a companion of crops. It is a basic theory of reform of culture and tillage in crop science. This research will be beneficial to the development of persistentusage of tillage and sustainable agriculture.
