从20世纪中叶起,以生物技术、信息技术新突破为标志的新的农业科技革命兴起,来势猛,起点高,作用大,影响深,使科技成为农业发展的主导力量。生物技术取得重大突破生物技术的核心是基因工程技术,它打破了动物、植物、微生物等不同物种间无法进行杂交的传统局限,改变了生物的遗传性能,使农业发展产生质的飞跃。把血红蛋白基因转移到玉米,提高了玉米的蛋白含量。将苏芸杆菌的杀虫蛋白基因定位于棉花中,棉花植株体自身产生杀虫蛋白,培育出了抗虫棉。这些转基因作物于1995年开
Since the middle of the 20th century, the new agricultural science and technology revolution marked by new breakthroughs in biotechnology and information technology has risen. It has become a fierce, high starting point, a large role, and a deep influence, making science and technology a dominant force in agricultural development. A major breakthrough in biotechnology The core of biotechnology is genetic engineering technology, which breaks the traditional limitations of the inability to cross between different species such as animals, plants, and microorganisms, changes the genetic properties of organisms, and leads to a qualitative leap in agricultural development. Transferring the hemoglobin gene to corn increases the protein content of corn. The insecticidal protein gene of Bacillus thuringiensis was localized in cotton, and the cotton plant body itself produced insecticidal protein and cultivated insect-resistant cotton. These GM crops were opened in 1995
