Negative pressure type sprinkling and dropping irrigation fertilization and pesticide application device and application method thereof

Abstract

The invention relates to a negative pressure type sprinkling and dropping irrigation fertilization and pesticide application device and its application method. The device provided by the invention comprises an inlet pipe, a water pump and an outlet pipe. A pipette with a first ball valve is connected in a pipe section of the inlet pipe. The pipette is connected with a first solution barrel. A water supply pipe with a second ball valve is connected in a pipe section of the outlet pipe. The water supply is connected with a second solution barrel. When the device is in use, by negative pressure generated by the inlet pipe during operation of the water pump, the pipette inhales a fertilizer solution of the first solution barrel, the fertilizer solution is mixed with water of the inlet pipe, and stirring blending is realized by the water pump. On one hand, sprinkling and dropping irrigation fertilization and pesticide application of the solution are realized; and on the other hand, the solution is transferred through the water supply pipe into the second solution barrel to be used as a solvent, and simultaneously, the second solution barrel undergoes dosing operation. When the fertilizer solution inside the first solution barrel is used up, the pipette is transferred into the second solution barrel, the water supply pipe is transferred into the first solution barrel, and the first solution barrel undergoes dosing once again. With the circulation, continuous fertilization and pesticide application are realized.

Description

technical field [0001] The invention relates to the field of sprinkler irrigation, and relates to a negative-pressure drip irrigation fertilization and pesticide application device and a method for using the same. Background technique [0002] At present, using the drip irrigation system to fertilize and apply pesticides to realize the "integration of water, fertilizer and medicine" can save 90% of labor, improve the quality of fertilization and pesticide application, and reduce the amount of fertilizer and pesticide. It is the direction of modern agricultural development. Common fertilization (medicine) devices on the market have many problems: 1. Differential pressure fertilization (medicine) tanks. Problem 1: After adding fertilizer (medicine) every time, when the fertilizer (medicine) solution is output and water is input at the same time, the concentration of the solution keeps decreasing linearly, which is uncontrollable. curve (see figure 2 ). Problem 2: There is a...
