Mulching film covering method for farmland ridge-and-furrow rainwater-harvested planting

The invention relates to a mulching film covering method for farmland ridge-and-furrow rainwater-harvested planting. The mulching film method includes the steps that the surface of a ridge body is covered with a mulching film, and the edge portions, on the two sides of the ridge body, of the mulching film is coiled inward in the direction of the ridge body and fixed. Compared with a traditional mulching film covering method, the mulching film covering method eliminates water stagnation regions formed by film-pressing soil on the film in a joint area of the ridge and a furrow, it is ensured that natural rainwater collected on the mulching film on the side of the ridge completely flows into soil in planting trenches in the farmland ridge-and-furrow rainwater-harvested planting process, fixation of the mulching film can be met, the mulching film is prevented from being uncovered by wind, it can be avoided that the film-pressing soil on the edges of the mulching film blocks, absorbs and dissipates drought-region farmland ridge surface rainwater converged runoff to makes rainwater unavailable, and the rainwater harvesting efficiency of the farmland ridge-and-furrow rainwater-harvested planting technology is further improved.

Eco-stagnation and filtration system with nitrogen removal function

The invention relates to an eco-stagnation and filtration system with a nitrogen removal function. The eco-stagnation and filtration system mainly comprises a stagnation zone and a filtration zone. The eco-stagnation and filtration system is constructed mainly from a municipal landscaping greenland. Through filling with a percolation matrix and plantation of specific plants, city overland runoff is delayed and is subjected to percolation. When overland runoff is produced on the water impermeable earth surface, initial heavy pollution runoff enters into the stagnation zone, then permeates into the stagnation zone, then is filtered, then permeates into the lower-middle part of the stagnation zone and is momentarily stored in the stagnation zone, and water collection and discharge pipes arranged at the bottom broken stone layer control a water flow amount so that the initial heavy pollution runoff can be retained for a long time and surface runoff NO<3>-N reduction time requirements are satisfied. When the initial surface runoff in the stagnation zone is saturated and overflows a water stagnation layer in the stagnation zone, later surface runoff overflows and enters into the filtration zone, then permeates into the filtration zone, then is filtered, then permeates into the broken stone layer at the bottom of the filtration zone, and then is discharged into a municipal rainwater pipe net by open water collection and discharge pipes in the broken stone layer.
