Description
Technical field
The invention belongs to the agricultural planting technique field, be specifically related to a kind of implantation methods that utilizes corn and broccoli, potato intercropping to control the farmland pollution of area source.
Background technology
The farmland pollution of area source refers to silt, nutritive salt, agricultural chemicals and other pollutant in the farmland, in precipitation or irrigation process, by agricultural surface runoff, interflow, agricultural drain and underground leakage, enters water body and the pollution of area source that forms.Along with the enhancing of China to the point-source pollution control ability, the farmland pollution of area source has become the primary pollution source in the waters such as lake.Such as the Dianchi Lake Basin in Yunnan Province in recent years along with the enforcement of basin point-source pollution Control Engineering, and the loss of the nutriments such as agricultural surface runoff nitrogen, phosphorus has become the primary pollution source that affects Water Quality of Dianchi Lake, has become one of the most serious lake of national water body eutrophication degree.
Crop planting model has important impact to soil erosion in farmland and rainwash, and the loss that rational cropping pattern can effectively be cut down agricultural surface runoff and nutriment has caused researcher's concern.Therefore, study different cropping patterns to the impact of the nutrients numbers of dropouts such as nitrogen, phosphorus in Dianchi Lake Basin agricultural surface runoff amount and the runoff, the cropping pattern of Farmland Flow Pollution is effectively cut down in screening, and the method for the minimizing farmland pollution of area source of science can be provided for lake treatments such as Dian Chi.
Summary of the invention
The technical problem to be solved in the present invention be overcome agricultural surface runoff amount that existing Dianchi Lake Basin farmland planting pattern causes large with runoff in the nutrients numbers of dropouts height such as nitrogen, phosphorus, fertilizing amount is too high, defective and the deficiencies such as the farmland pollution of area source is serious provide a kind of easy, easy grasp, the low effective profit that drops into
