生物技术是常规育种技术的补充、提高和创新。实践证明 ,生物技术只有与常规育种技术紧密结合 ,才能真正发挥它的优势 ,加快育种进程 ,提高育种水平。生物技术是利用生物体系和工程原理生产生物制品和创造新物种的综合科学技术 ,也称生物工程。它主要包括 4个领域 :基因工程、 Biotechnology is the complement, enhancement and innovation of conventional breeding techniques. Practice has proved that only with the combination of conventional breeding technology, biotechnology can really play its advantages, speed up the breeding process and improve the breeding level. Biotechnology is a comprehensive science and technology that uses biological systems and engineering principles to produce biological products and create new species, also known as bioengineering. It mainly includes four areas: genetic engineering,
