The invention relates to a
saline-
alkali soil water collection irrigation and drainage dual-purpose
ditch which comprises a plurality of
water collection ditches. The bracket is detachably connected to the top of the water collecting
ditch and is formed by splicing a plurality of sections; the rainwater collecting
irrigation mechanism comprises a rainwater collecting
assembly, a first-stage
irrigation assembly and a second-stage irrigation
assembly, and the rainwater collecting irrigation mechanism has a rainwater collecting mode, a natural irrigation mode and a strong irrigation mode; in rainy days, the rainwater collecting irrigation mechanism is in a rainwater collecting mode, and the rainwater collecting assembly is started to collect rainwater into the water collecting
ditch; when the water in the water collecting ditch is sufficient, the rainwater collecting irrigation mechanism can be in a natural irrigation mode, and the first-stage irrigation assembly is started; when the rainwater collecting irrigation mechanism is in a strong irrigation mode, the secondary irrigation assembly is started, anti-seepage cloth is laid on the inner wall of the water collecting ditch, concealed pipes are buried below the bottom wall of the water collecting ditch, and the anti-seepage cloth is located above the concealed pipes. The
system can realize collection, storage and utilization of rainwater, provides necessary
fresh water resources for improvement of the
saline-
alkali soil, is combined with the concealed pipes, does not affect drainage, and has double effects of
water collection irrigation and salt drainage.
