实施科学灌溉　发展节水农业──广西大面积水稻节水灌溉技术开发

Carry Out Scientific Irrigation for Developing Water-Saving Agriculture

水稻是我国南方的主要粮食作物，也是耗水大户，传统的串灌、漫灌，不仅造成水量浪费严重，而且不利于水稻的生长，严重制约着农业的发展。实践证明，根据水稻需水的规律进行科学灌溉，不仅可以大量节水，而且还能增产，社会效益和经济效益都十分显著。

Rice is a major food crop of south China and a huge water consummer also. The traditional field to field and flooding irrigation not only waste water but also are harmful to rice growing and seriously restrict agriculture development. The practice has proved that the scientific irrigation based on rice water requirement rule can save water and increase yield and gain significant social and economic benefits as well.
