A drip irrigation and fertilization system

Abstract

The invention relates to a drip irrigation and fertilization system. The drip irrigation and fertilization system comprises a fixing frame, wherein a fertilizer liquid tank is arranged in the fixing frame; a motor is arrange at the top of the fixing frame; a rotating shaft is connected to an output shaft of the motor; a bearing block is arranged at the center of the top of the fertilizer liquid tank; the rotating shaft penetrates through the bearing block and enters the fertilizer liquid tank; a rotor is arranged at the tail end of the rotating shaft; a liquid filling inlet and a liquid returning port are respectively formed in the upper part of the fertilizer liquid tank; a liquid level meter is arranged at the left side of the lower part of the fertilizer liquid tank; a liquid outlet is formed in the right side of the lower part of the fertilizer liquid tank; an inlet of a pump is connected to the liquid outlet through a liquid outlet pipe; a port A of a four-way joint is connected to an outlet of the pump through an electromagnetic valve A; a port B of the four-way joint is connected with the liquid return port through a one-way valve and a pressure valve; a drip irrigation pipe is connected to a port C of the four-way joint. The drip irrigation and fertilization system disclosed by the invention has the advantages of simple structure, sufficient dissolving of fertilizer and reduction of blockage.

Description

technical field [0001] The invention belongs to the technical field of water-saving irrigation, and in particular relates to a drip irrigation and fertilization system. Background technique [0002] With the popularization and application of water-saving irrigation technology, the water-fertilizer integration technology that combines irrigation and fertilization has been widely used in modern agricultural production. It dissolves fertilizer and pours it into the irrigation system, through pipes and drippers. Drip irrigation is formed, and it is directly, uniformly and quantitatively applied to the root layer of crops, so that the main root soil always maintains looseness and suitable water content, truly realizes the synchronization of water and fertilizer, greatly improves the utilization rate of fertilizers, increases production and income, and improves production efficiency. However, In the process of water and fertilizer integration, undissolved fertilizers or impurities...

[0002] With the popularization and application of water-saving irrigation technology, the water-fertilizer integration technology that combines irrigation and fertilization has been widely used in modern agricultural production. It dissolves fertilizer and pours it into the irrigation system, through pipes and drippers. Drip irrigation is formed, and it is directly, uniformly and quantitatively applied to the root layer of crops, so that the main root soil always maintains looseness and suitable water content, truly realizes the synchronization of water and fertilizer, greatly improves the utilization rate of fertilizers, increases production and income, and improves production efficiency. However, In the process of water and fertilizer integration, undissolved fertilizers or impurities in the water will often block the drippers in the pipes, affecting the effect of fertilization, and in severe cases, the entire irrigation system will not work properly. In order to overcome this problem, it is necessary to develop a Drip Fertigation System
