近年来,农业节水灌溉技术在我省发展很快,从技术上可归纳为减少水量渗漏及蒸发损失的工程、农艺措施和推广农作物节水型灌溉制度的管理措施。工程措施大体可分渠道衬砌防渗、管道输水和喷滴渗灌。现仅对渠道衬砌防渗作一简介。在渠道上砌筑或衬保护层,用以阻止水在输送过程中的沿程滲漏,有下面几种:1.浆砌石衬砌:有块石、卵石、砖三种形式。这是一种就地取材、防冲防渗的好方法,目前采用
In recent years, agricultural water-saving irrigation technology developed rapidly in our province, from the technical can be reduced to reduce water leakage and evaporation loss of the project, agronomic measures and the promotion of crop water-saving irrigation system management measures. Engineering measures can be divided into general channel lining seepage control, pipeline water and drip infiltration irrigation. Now only for the canal lining seepage for a brief introduction. In the channel masonry or lining protective layer, to prevent the water in the process of transmission along the process of leakage, there are the following: 1 masonry lining: a stone, pebbles, bricks in three forms. This is a good way to draw on the spot and prevent seepage and seepage. It is currently used
