随着遗传学、细胞生物学和分子生物学的发展,近年来生物技术已经成为一门深受世人瞩目的新兴学科。“生物技术”这一名词虽然在我国早被人引用,但当代的“生物技术”则是指:利用生物体或生物有机体来制造或改进产品、改良品种或培育微生物供特完用途的新技术。这与农史上所称的“生物技术”大有径庭之别。生物技术是高技术的重要发展领域之一。它包括细胞工程、基因工程、发酵工程和酶工程。农业生物技术作为生物技术的重要主体之一,就是包括上述“四大工程”应用于种植业、养殖业和垦殖业开发新的高技术产品。从行业来说,农业生物技术跨越种 With the development of genetics, cell biology and molecular biology, in recent years, biotechnology has become a new emerging subject which has attracted worldwide attention. Although the term “biotechnology” has long been cited in our country, contemporary “biotechnology” refers to the use of organisms or biological organisms to make or improve products, improve varieties or cultivate new technologies for end-use applications . This is in contrast with the so-called “biotechnology” in agricultural history. Biotechnology is one of the important development areas of high technology. It includes cell engineering, genetic engineering, fermentation engineering and enzyme engineering. As one of the major subjects of biotechnology, agricultural biotechnology includes the application of the above “four major projects” in the development of new hi-tech products in crop farming, aquaculture and reclamation. From the industry, agricultural biotechnology crosses species
