An integrated irrigation device for field water and fertilizer

Abstract

The invention belongs to the field of tobacco irrigation equipment, and in particular relates to an integrated irrigation device for field water and fertilizer, which includes several irrigation pipes for connecting water pumps. There are several water outlets at the same axial distance on the side wall of the pipe, and the water outlets are equipped with a plugging mechanism. The side wall of the inner pipe is provided with a counterweight for connecting the inner wall of the outer pipe at the symmetrical position of the water outlet, and the cross-section of the counterweight It is a fan ring with the radius of the inner pipe as the inner radius and the outer radius as the outer radius; bearings are arranged at both ends of the irrigation pipe and the bearings are arranged on the bracket, and the device also includes a pressure-reducing mechanism arranged on the top of the drain pipe. The invention has a simple structure, can make the drainage pipes at each plant supply water as simultaneously and uniformly as possible, and can reduce the water pressure so that the water can be leveled and flow into the ridge soil, so as to improve the irrigation efficiency.

Description

technical field [0001] The invention belongs to the field of agricultural irrigation equipment, in particular to an integrated irrigation device for field water and fertilizer. Background technique [0002] Tobacco is a large herbaceous plant planted on ridges. The existing technology often uses rough and simple flood irrigation between ridges to irrigate it. However, in recent years, it has been found that this method is easy to cause mutual infection of diseases between tobacco plants, especially those with high mortality rate. Bacterial diseases such as black shank and root black rot are more likely to be infected through water. At the same time, the ineffective evaporation rate of water in flood irrigation between ridges is higher, resulting in waste of water resources. In the prior art, methods similar to sprinkler irrigation are also used to irrigate tobacco plants, such as puncturing plastic pipes at equal intervals so that each hole is irrigated corresponding to the...

Problems solved by technology

However, there are two disadvantages in this method: 1) When the pump pumps water into the pipeline, the holes closer to the pump are the first to discharge water, and the holes farther away are the last to discharge water, resulting in water supply and fertilizer supply between the tobacco plants. Unevenness, especially excessive application of nitrogen fertilizer, will easily lead to green and late maturity of tobacco leaves, which will cause the tobacco leaves in the field to fail to fall and mature uniformly; 2) The pump pressurizes the water, resulting in high pressure of water flow discharged from the hole, which not only easily causes ridge soil erosion and collapse At the same time, the water flow is easy to splash to other places, and it also exacerbates the problem of the difference in fertilization amount caused by the different water outlet time.
