我国是世界上严重缺水的国家之一，人均占有水量仅为世界人均水量的四分之一。而我国农业用水量很大，占年用水总量的SO％以上，有效利用率却很低。故我国农业在向节水型农业发展。从1988年起，我们在水稻上进行了节水灌溉研究，通过多点试验、监测田反馈信息、丰产片示范，摸 Our country is one of the countries with serious water shortages in the world, with the per capita water consumption only a quarter of the world’s per capita water consumption. China’s agricultural water consumption is very large, accounting for more than SO% of the total annual water consumption, but the effective utilization rate is very low. Therefore, China’s agricultural development in water-saving agriculture. Since 1988, we conducted a water-saving irrigation research on rice, through multi-point test, monitoring field feedback, demonstration of high yield film, touch
