的确,美国的农业是不多的几个能在激烈的国际竞争中称雄的强项之一。年年生产的粮食大量过剩,需要社会对这些粮食的最终储存进行大力投入;政府要花费巨额用于价格补贴,以保证面对生产过剩农民的收入。是否可用植物技术学解决这些问题呢? 过去的2～3年里,在世界范田内几个实验室里的研究人员,已拥有了包括马铃薯和烟草这类普遍作物 Indeed, American agriculture is one of the few strengths that can dominate the fierce international competition. The large amount of food produced each year requires the society to invest heavily in the final storage of these foods; the government must spend a huge amount on price subsidies to guarantee the income of the over-produced farmers. Is it possible to solve these problems with plant technology? In the past two to three years, researchers in several laboratories in the world have already had such universal crops as potatoes and tobacco.
