高产高效吨粮田开发是我国农业生产的一项创举,特别是整建制吨粮田开发的实施与扩大,把农业生产提高到一个新水平。90年代以来,吨粮田开发发展迅速,1996年全国已有6500多万亩耕地实现亩产吨粮,有40个县(市)先后跨进整建制吨粮田开发的行列;还出现了湖南株洲、湘潭和广东汕头整建制吨粮田开发(地级)市。高产优质高效吨粮田开发,是现代科技进步与 High-yield and high-efficiency grain-tonnage development is a pioneering work of agricultural production in our country. In particular, the implementation and expansion of whole-grain tonnage field development has brought the agricultural production to a new level. Since the 1990s, the development of the grain cropland has been developing rapidly. In 1996, more than 65 million mu of cultivated land had been planted nationwide to produce tons of grain per mu. In 40 counties (cities) Zhuzhou, Xiangtan and Shantou, Guangdong whole ton of grain field development (prefecture-level city. High-yield, high-quality and high-yielding tons of grain field development is the progress of modern science and technology
