Embodiment Construction

[0013] (2) Test materials and methods

[0014] The test materials are greenhouse vegetables.

[0015] 113 groups of field experiments were carried out in the intensive facility agricultural production base of Shangsuan Township, Jinning County.

[0016] 1. Source control test

[0017] (1) Screening and optimal allocation of high-efficiency nitrogen and phosphorus species for pollution prevention and control

[0018] Utilize the differences in the use of nitrogen and phosphorus nutrients among different varieties of vegetables to screen out varieties with high nitrogen and phosphorus utilization; then use the reciprocal effects of the screened varieties with high nitrogen and phosphorus utilization to optimize allocation, regulate vegetable planting structure, and coordinate water and fertilizer supply. Improve the effective utilization rate of nutrients and establish a pollution prevention and control farming system with sustainable development (the balance between economic ...

Abstract

The invention belongs to the technical field of environment protection, and relates to a facility agricultural non-point source pollutant on-site intercepting and absorptive method. By the aid of a triple intercepting and absorptive method of source control, process blocking and intercepting and destination absorption and fixation of facility agricultural pollutants, non-point source pollution sources-flow-convergence processes and water-fertilizer key factors determining forming of non-point source pollution are subjected to process key point control, and on-site reduction of facility agricultural non-point source pollution is achieved by means of reducing consumption of nitrogen and phosphorus, increasing nitrogen and phosphorus absorption, preventing nitrogen and phosphorus loss and recycling nitrogen and phosphorus. By the method, nitrogenous fertilizer input of facility farmlands is decreased by 35%, phosphate fertilizer input is decreased by 22%, chemical pesticide input is decreased by 41.4%, agricultural waste recycling and harmless treatment utilization rate reaches 91.7%, treatment cycle is shorted by 46.2%, nitrogen is reduced on site by 38.45%, and phosphorus is reduced by 25.42%. The method can be widely applied to interception and control of facility agricultural non-point source pollutants.

Description

[0001] technical field [0002] The invention relates to the technical field of environmental protection, in particular to an on-site triple interception and consumption method for facility agricultural non-point source pollutants. Background technique [0003] Nitrogen and phosphorus are the main pollutants of agricultural non-point source pollution. Facility agriculture is an important vegetable production base in my country, and it is also an important source of agricultural non-point source pollution. This area releases a large amount of nitrogen and phosphorus into the environment as the main form of pollution. The facility agriculture area has a large area, wide distribution, and high multiple cropping index. While the output and output value have increased substantially, the input intensity of chemical fertilizers is high (but the utilization rate of nitrogen fertilizer is only 30% to 35%, and the utilization rate of phosphorus fertilizer is 10% to 20%). A large amou...
