Embodiment 1

[0022] This example takes a typical vegetable intensive planting base in the Taihu Lake Basin as the demonstration object.

[0023] Such as figure 1 As shown, the original farmland ditch was transformed into a channel with a trapezoidal cross section. Cement boards with holes were laid in parallel on both sides of the ditch 1, and 8-shaped grass-planting bricks were laid in parallel on the bottom 2 of the ditch.

[0024] Such as figure 2 As shown, the cement slab with holes in the canal wall is 5 cm thick, 60 cm long, and 60 cm wide. The diameter of the round hole is 8 cm, and the hole spacing is 20 cm. It is a reinforced concrete structure. Perennial plants with high element absorption capacity and strong environmental adaptability, choose perennial emergent plants——Mushroom Grass ( Hydrocotyle vulgaris ).

[0025] Such as image 3 As shown, 8-shaped grass-planting bricks are laid on the bottom of the canal. The bricks are 8cm thick, 40cm long, and 20cm wide. In the hol...

Abstract

The invention relates to the field of non-point source pollution control engineering and discloses an efficient ecological interception ditch suitable for dry land farmlands. The cross section of the ditch is of a trapezoid, the ditch wall surfaces of two sides of the ditch are provided with concrete boards with holes in a laying mode, the bottom of the ditch is provided with grass planting bricks which are 8-shaped in a laying mode. The concrete boards utilize reinforced concrete structures, the surfaces of the concrete boards are provided with 6 to 9 holes which are distributed evenly and at intervals, and hydrocotyle vulgaris is planted in every hole. The efficient ecological interception ditch suitable for the dry land farmlands is simple, efficient, practical, economical, easy to maintain, convenient to popularize and capable of solving problems of the severe eutrophication of periphery water and the huge nutrient element loss of N (nitrogen), P (phosphorus) and the like in farmland planting processes.

Description

technical field [0001] The invention relates to the field of non-point source pollution control engineering, in particular to a high-efficiency ecological interception ditch suitable for dry farmland. Background technique [0002] Farmland non-point source pollution refers to the environment formed by the surface runoff and seepage of farmland through the surface runoff and farmland seepage of nutrients such as nitrogen and phosphorus, pesticides, and other organic or inorganic pollutants during farmland production activities. Pollution mainly includes chemical fertilizer pollution, pesticide pollution, livestock and poultry manure pollution, farmland solid waste pollution, etc. With the continuous increase of fertilizer consumption in the process of farmland planting, the content of nitrogen and phosphorus in farmland soil and the loss of nitrogen and phosphorus continue to increase, resulting in increased environmental pollution of farmland soil and water bodies. At prese...
