二十年前开始的绿色革命被认为是世界农业发展的最重要成就之一。在一些第三世界国家使用高产的农作物杂交新品种是这次绿色革命最基本的技术策略。然而,第三世界中仅1/3的农田从这场绿色革命中受益,许多发展中国家仍然面临着粮食短缺问题。本文概述了绿色革命之后第三世界农业的一些情况和新绿色革命的某些技术策略。文章指出,某些现代生物技术(如组织培养和重组DNA)与生态农业技术相结合,将成为第三世界发展新的绿色革命的基本策略。本文还列举了一些实例。
The green revolution that began 20 years ago is considered one of the most important achievements in world agricultural development. The use of high-yielding new crop hybrids in some Third World countries is the most basic technical strategy of this green revolution. However, only one-third of the farmland in the Third World has benefited from this green revolution, and many developing countries still face the problem of food shortages. This article outlines some facts about agriculture in the Third World after the Green Revolution and some of the technical strategies of the New Green Revolution. The article points out that the combination of some modern biotechnology (such as tissue culture and recombinant DNA) and eco-agricultural technologies will become the basic strategy for the Third World to develop a new green revolution. This article also lists some examples.
