- Phosphorus efficiency and water productivity of aerobic rice under different water regimes
不同水分条件下旱稻磷效应及水分生产率 - Some countermeasures are developed against these problems : ( 1 ) building water diversion works from other river basin under a comprehensive program ; ( 2 ) strengthening the measures of local sewage treatment and other place sewage control ; ( 3 ) raising water productivity by using water - saving techniques ; and ( 4 ) improving the management of water use
针对这些问题提出了若干对策： ( 1 )认真搞好供水规划，积极争取外调水； ( 2 )加大污水治理力度，包括上游来水的水质控制； ( 3 )搞好节水规划，提高工农业用水的利用效率； ( 4 )健全和理顺水管理体制。 - Due to the underdevelopment of economy , traditional surface irrigation such as border and furrow irrigation is still taken as the dominant way in farmland irrigation , which leads to the great waste of water resources . therefore , how to apply a new theory to study and improve surface irrigation technique in order to increase water use efficiency and water productivity in farmland , has become a key project in water - saving research of agriculture today
然而，由于经济欠发达，我国农田灌溉仍以传统的畦、沟地面灌溉技术为主，水资源浪费现象还比较严重，因此，如何运用新的理论研究和改进地面灌水技术，提高农田水分利用效率和水的生产效率，已成为当今我国农业节水研究的重点课题。
