由真菌引发的稻瘟病是水稻最主要的疾病。已有科学理论提出,水稻品种的遗传多样性可能是解决单种栽培水稻易遭受疾病侵害的一种方法,但一直缺乏实验数据。最近在云南省农田里所进行的试验证实了这一科学观点:在同一农田种植不同品种的水稻可阻止某种水稻疾病的扩散,从而提高产量。数千名当地农民参加了这一实验,研究人员的实验同时也让农民们接受了这一科学理论。1998年,根据朱有勇的建议,当地农民开始在云
The rice blast caused by fungi is the most important disease in rice. It has been suggested by scientific theory that the genetic diversity of rice cultivars may be one way to solve the vulnerability of cultivated rice to disease. However, there is a lack of experimental data. Recent experiments in farmland in Yunnan Province confirm the scientific view that planting different varieties of rice in the same farmland can prevent the spread of certain rice diseases and increase production. Thousands of local farmers took part in the experiment, and researchers’ experiments also allowed the farmers to accept the scientific theory. In 1998, according to Zhu Youyong’s suggestion, local farmers began to cloud
