随着我国经济的发展,国家对农业发展和投入也越来越大,相关的农业水利技术也飞速发展。然而,我国广泛分布的大量小型农田的水利灌溉渠道大都显得过于老旧,因此,在以农业发展、农产量增加的迫切需要下,对我国小型农田水利工程渠道进行合理设计成为日渐紧迫的任务。 With the economic development of our country, the state has also made greater and greater efforts in agricultural development and investment, and related agricultural and water conservancy technologies have also developed rapidly. However, a large number of small-scale farmland widely distributed in our country have mostly old water irrigation channels. Therefore, under the urgent need of agricultural development and increasing agricultural output, it is an increasingly urgent task to design a reasonable channel for small farmland water conservancy projects in our country.
