Nitrogen circulation treatment system and method for zizania latifolia planting

Abstract

The invention discloses a nitrogen circulation treatment system and method for zizania latifolia planting. The system comprises a planting field, a storage pond and a nitrogen purifying tank, wherein a water level control device is arranged on the left side of the planting field, a water feeding pipe is arranged above the left side of the planting field, a filtering device is arranged on the right side of the planting field, and the planting field is connected with the storage pond through a first overflow pipe; the bottom end of the left side of the storage pond is connected with the feeding pipe through a first circulating pipe, and the storage pond is connected with the nitrogen purifying tank through a second overflow pipe; the bottom end of the left side of the nitrogen purifying tank is connected with the water feeding pipe through a second circulating pipe, the right side of the nitrogen purifying tank is connected with a river channel through a drainage pipe, a draining pump is arranged on the drainage pipe, the drainage pipe is connected to the bottom of the nitrogen purifying tank, and a nitrogen filtering mechanism is arranged in the nitrogen purifying tank. The steps of the method are simple, stability of the water level in the planting field can be maintained, besides, nitrogen loss is reduced, environmental pollution is reduced, planted zizania latifolia is high in quality and yield, and the economic benefits are remarkable.

Description

technical field [0001] The invention relates to a nitrogen cycle treatment system and method for planting wild rice stems. Background technique [0002] Zizania as an economic crop has improved the economic income of farmers to a certain extent. However, in recent years, in order to pursue higher profits, farmers have excessively applied chemical nitrogen fertilizers. The low utilization rate of nitrogen fertilizers has caused unbalanced application of soil nutrients and serious waste. [0003] During the production of Zizania zizania, the nitrogen lost by runoff directly enters the surface water body, seriously polluting the water quality of the river course, and the nitrogen lost by leakage pollutes the groundwater body, which poses a great threat to the safety of drinking water for residents. Excessive chemical fertilizers cause soil With the deterioration of the nature, the quality of Zizania will also be affected. Contents of the invention [0004] The purpose of the...
