[0002] Grassed ditches refer to surface ditches planted with vegetation, which can collect, transport and discharge runoff rainwater and have a certain rainwater purification effect. They can be used to connect other individual facilities, urban rainwater pipe systems and excessive rainwater runoff discharge systems. In addition to transmission-type grassed ditches, they also include infiltration-type dry grassed ditches and wet grassed ditches with water, which can increase the total runoff volume and runoff pollution control effects respectively.

[0003] After planting flowers and plants, dry grass-planting ditches can retain an appropriate amount of rainwater for the growth of flowers and plants. However, when encountering long periods of sunny weather or drought, the retained rainwater will be quickly consumed, and the flowers and plants in the grass-planting ditches have to be watered regularly by a sprinkler truck or other methods for maintenance, which not only increases manpower and economic investment, but also causes a waste of water resources. To this end, the utility model proposes a dry grass-planting ditch soil and water conservation device for solving the above problems. Utility Model Content
