Embodiment Construction
[0010] The utility model relates to a single-side drainage ditch for dry farmland, with dry farmland on one side and field roads on the other side. It is made of bricks and cement, and consists of ditch walls on both sides, ditch bottom and ditch body. Among the ditch walls 1 on both sides, there are side seepage outlets 2 and runoff outlets 3 on the ditch wall 1 close to the side of the dry farmland, and the ditch wall on the other side is a solid wall; the side seepage outlet 2 is on the ditch wall 1 1. The downward vertical gap left between bricks on the same horizontal plane below the soil surface, and the runoff outlet 3 is a drainage gap at the bottom of the retaining wall that is lower than the ground. The width of the side seepage outlet 2 is 0.2cm, the width of the runoff outlet 3 is 20cm, and the bottom is 18cm lower than the ground.

The invention discloses a one-sided drained drainage ditch of a dry farming land, wherein one side of the one-sided drained drainage ditch is a dry farming land, and the other side is a field road. The ditch wall at one side closing to the dry farming land is provided with a lateral seepage draining opening and a radial flow draining opening. The one-sided drained drainage ditch is good for rapid implementation of the field radial flow of the dry farming land and also making lateral seeped water in the farmland soil smoothly flow. The one-sided drained drainage ditch improves the water permeable performance of the dry farming land soil and promotes the coordination of water and air in the soil, and is also good for the growth of crops.
Description
technical field [0001] The utility model relates to a dry farmland drainage ditch with one side drainage, which relates to the drainage ditch technology of the farmland, more specifically, a drainage ditch for the dry farmland. Background technique [0002] In some agricultural scientific research institutes and agricultural companies, for the stability, standardization and reliability of field test conditions, cement and bricks were used to build drainage ditches in the dry farmland, and some drainage outlets were opened above the ditch wall to communicate with the field. The drainage ditches are connected to each other and are used for drainage of farmland runoff, while the other parts of the ditch walls are made of cement and bricks and are impermeable structures. This kind of ditch wall has an adverse effect on the fresh water and air permeability of dryland farmland soil, especially in the rainy and sticky soil areas in the south. After irrigation or rainfall, farmland...
