Farmland irrigation device for water conservancy projects, and irrigation method thereof

Abstract

The invention discloses a farmland irrigation device for water conservancy projects. The farmland irrigation device comprises planting areas and a water drainage and storage area. The water drainage and storage area is arranged between the planting areas. Spray irrigation systems arranged on the planting areas are connected with the water drainage and storage area. Buffer mechanisms are arranged between the water drainage and storage area and the spray irrigation systems. The water drainage and storage area comprises an upper water storage tank, a lower water storage tank and a middle protection component. The upper water storage tank is arranged between the two planting areas, the middle protection component is mounted at the bottom of the upper water storage tank, and the lower water storage tank is arranged at the bottom of the middle protection component. The farmland irrigation device has the advantages that space-time regulation of rainwater is realized to ensure sufficient waterin the planting areas; the buffer mechanisms are mounted between the water drainage and storage area and the spray irrigation systems, pesticide and fertilizer can be applied in a targeted way, and management of the planting areas can be facilitated; the safety of the water drainage and storage area is improved through the middle protection component, and residues on the middle protection component are conveniently cleaned.

Description

Technical field: [0001] The invention belongs to the technical field of farmland irrigation, in particular to a farmland irrigation device for water conservancy projects and an irrigation method thereof. Background technique: [0002] Economic crops usually have the characteristics of strong regionality, high economic value, high technical requirements, and high commodity rate. They have strict requirements on natural conditions and are suitable for centralized specialized production. While economic crops bring high value, they also require high planting management. In my country, there are distinct rainy seasons and dry seasons. Excessive drought in the dry season and excessive rainfall in the rainy season are likely to cause crop yield reduction or even crop death. [0003] At present, ditches are built in the planting area for irrigation in the dry season. In order to increase the water storage capacity, the ditch is generally deep and wide, and it is easy to fall off. The...

Problems solved by technology

[0004] The purpose of the present invention is to provide a farmland irrigation device and irrigation method for water conservancy projects in order to solve the above problems, which solves the problem of the general depth and width of ditches in order to increase water storage by building ditches in planting areas for irrigation in dry seasons. Larger, prone to falling, poor safety, and the bottom of the ditch is deep, it is difficult to clean, and the pesticide and nutrient solution are added to the water storage tank as a whole, and the residual amount in the water storage tank is relatively large. The shortcomings of pesticides and fertilization can not be targeted according to different crops in the planting area, and the effectiveness of pesticides and fertilization is poor
