Integrative device of nebulization and trickle irrigation and irrigation method thereof

Abstract

The invention provides an integrative device of nebulization and trickle irrigation. The device comprises a water storage tank, a water inlet valve, a water inlet pump, a filter device, a fertilizer transport system, a blending device, a pressure pump for trickle irrigation, a trickle irrigation machine, a controller and a sensor group, wherein the filter device is used for primary filtration of an irrigation water source; the fertilizer transport system comprises a fertilizer tank and a pressure pump which is connected to the fertilizer tank through a pipeline and provided with a water valve for adjusting on the pipeline; the blending device is used for blending the water from the water storage tank with the fertilizer from the fertilizer tank according to a proportion to prepare a fertilizer solution; the pressure pump for trickle irrigation is used for pressurizing and pumping up the fertilizer solution; the trickle irrigation machine is used for conducting trickle irrigation; the sensor group is used for monitoring the growing environment of crops; the controller is used for controlling the operation of the device. The integrative device of nebulization and trickle irrigation is capable of realizing precise fertilizer preparation, scientific fertilization according to environmental parameters of water, soil and air, and has the advantages of extremely boosting utilization ratios of water and fertilizer, and improving irrigation efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation machinery, in particular to an integrated device for atomization and drip irrigation and a method for irrigating by using the device. Background technique [0002] In the production management of agricultural greenhouses, irrigation, fertilization and pesticide application are important components of agricultural work. Traditional irrigation generally adopts border irrigation or flood irrigation, which wastes a lot of water during transportation and in the non-root system area. Fertilizer flows with water or artificially fertilizes the surface of the crop gap, resulting in fertilizer remaining in the transportation channel or surface and some roots cannot reach. In places where fertilizer is not available, it not only fails to achieve fertilizer effect but also pollutes the soil; in the process of root and soil pesticide application, water or manual application is also used, result...

AI Technical Summary

Problems solved by technology

Traditional irrigation generally adopts border irrigation or flood irrigation, which wastes a lot of water during transportation and in the non-root zone. Fertilizer overflows with water or artificially fertilizes and falls on the surface of crop gaps, resulting in fertilizer remaining in the transportation channel or on the surface and some roots cannot reach. In some places, not only the fertilizer effect is not achieved but also the soil is polluted; the roots and soil are also sprayed with water or artificially in the process of pesticide application, resulting in uneven application, inaccurate application positions, polluting the soil, and wasting the power of the pesticide.

The traditional spraying method is manual spraying. This method of operation is likely to cause uneven spraying. The liquid medicine basically stays on the upper surface of the plant leaves, and the lower surface cannot be sprayed or sprayed very little. Moreover, manual spraying is harmful to the operator. certain health damage

Traditional fertilization, pesticide application and irrigation have extremely rough time and frequency control, and the concentration of pesticide application and fertilization is uneven, and does not consider the conditions of crop growth, soil fertility, air temperature and humidity at that time
