A drip irrigation system

Abstract

The invention is mainly applied to the field of irrigation and fertilization in an apple planting process and in particular relates to a drip irrigation system. The system comprises a pump house head, a field head and a field pipe network. The pump house head comprises a water pump, an automatic backwash filter and a fertilizer injection device, wherein a water inlet end of the water pump is connected with a water pipe; an end of the water pipe is provided with a first filter; a water outlet end of the water pump is connected with the automatic backwash filter; a water outlet end of the automatic backwash filter is connected with the field head via a mixing pipe; the fertilizer injection device comprises fertilizer injection tanks which are connected with proportional fertilizer injectors via pipes; the proportional fertilizer injectors are connected with the mixing pipe via fertilizer injection pipes; one end of a water intaking hose is connected with the mixing pipe and the other end is connected with the fertilizer injection tanks. The drip irrigation system realizes water drip irrigation and fertilizer drip irrigation at the same time and prevents damage to the water pump and the pipe network; the service life of the system is prolonged and maintenance is convenient; the intelligent control system realizes intelligent irrigation and fertilization, increases the irrigation and fertilization efficiency, reduces manual operation and improves quality.

Description

technical field [0001] The invention relates to a drip irrigation system, which is mainly used in the field of irrigation and fertilization in the apple planting process. Background technique [0002] At present, in the field of agricultural planting science and technology, drip irrigation has been widely used. Drip irrigation is an irrigation method that slowly and evenly drips water with a certain pressure into the soil near the roots of plants in the form of water droplets through the pipe network and outlet pipes (drip irrigation belt) or drippers after filtering. Under the condition of drip irrigation, the effective utilization rate of water is high, and the irrigation water wets part of the soil surface, which can effectively reduce the ineffective evaporation of soil moisture. At the same time, since drip irrigation only moistens the soil near the roots of crops, and the soil moisture content in other areas is low, it can prevent the growth of weeds, drip irrigation ...

AI Technical Summary

Problems solved by technology

However, the current drip irrigation system is a single water drip irrigation, and another drip irrigation system needs to be installed for fertilization drip irrigation, which leads to an increase in cost, and the existing drip irrigation system often has water hammer during use. The water pump and the pipe network cause harm, the service life is short, and it is inconvenient to maintain
