FIELD: agriculture.

SUBSTANCE: apparatus comprises a base station and a network of pipelines for adding gas and fertilizer. Station comprises an accumulating tank, a gasifier, an output device and a dosing device for mixing gas and fertilizer. Accumulating tank contains accumulating tank for carbon dioxide, storage tank for sulfur dioxide, storage tank for ammonium nitrogen or oxynitride and storage tank for swamp gas, natural gas, methane or liquefied gas, which are arranged in parallel. Gasifier contains the first gasifier, the second gasifier, the third gasifier and the fourth gasifier. Output device comprises first output device communicated with first gasifier, second output device communicated with second gasifier, third output device, communicated with third gasifier, and fourth output device communicated with fourth gasifier. First output device, the second output device, the third output device and the fourth output device have the same design. First output device contains the first outlet pipeline and the second outlet pipeline, which are arranged in parallel. First outlet pipeline is serially equipped with a manual valve, the first decompression pressure stabilizer and a manual valve. Second discharge pipeline is serially equipped with a pressure sensor, a manual valve, a safety valve and a pressure sensor. Accumulating tank can provide one gaseous carbon dioxide or multiple mixed gases. Dosing device for gas and fertilizer mixing is divided into gas and water mixing section and gas mixing tank in compliance with various applications: for agricultural crops planted by dry farming, for crops planted in greenhouses, and for crops planted on irrigated rice fields. Liquid carbon dioxide in storage tank for carbon dioxide sequentially passes through first gasifier and decompression pressure stabilizer by means of outlet pipeline valves for liquid phase, and then flows back into storage tank for carbon dioxide. Valve pipeline for gas phase accumulating tank for carbon dioxide is communicated with first output device. Second output device, the third output device and the fourth output device are connected in parallel, and then connected to the multi-component mixing controller. At that, as multicomponent mixing regulator, and the first outlet device are connected to the pipeline for gas and fertilizer movement. One end of the gas and fertilizer transfer pipeline communicates with the gas and water mixing section, the other end of the pipeline for gas transfer and fertilizer is communicated with the gas mixing tank. Gas and water mixing compartment and gas mixing tank are respectively communicated with gas and water transfer pipeline and gas transfer pipeline. Both pipeline for gas and water transfer, and gas transfer pipeline are equipped with induction devices and electromagnetic bypass valves. Induction device comprises wind speed inductor, lighting inductor and time controller. Wind speed inductor and lighting inductor respectively control opening and closing of electromagnetic bypass valve by inducing value of wind speed and illumination intensity. Time controller controls opening and closing of the electromagnetic bypass valve by means of regulation of duration of time. Pipeline for gas and water transfer and gas transfer pipeline are interconnected with gas and fertilizer supply pipelines. Crop yield increase system based on above-described device comprises a system for multicomponent dosing and mixing of gas and fertilizer and a system of pipelines for adding gas and fertilizer. System for multicomponent dosing and mixing of gas and fertilizer comprises carbon dioxide storage system, gasification decompression system and gas and fertilizer dosing and mixing system, which are interconnected. Gas and fertilizer dosing and mixing system is divided into gas and water dosing and mixing system or gas dosing and mixing system in compliance with various applications: for agricultural crops planted by dry farming, for crops planted in greenhouses, and for crops planted on irrigated rice fields. Pipeline system for feeding gas and fertilizer comprises system of pipelines for movement and system of pipelines for application, which are interconnected. Dosing and mixing system of gas and fertilizer is communicated with system of pipelines for displacement. Pipeline system for movement controls message with pump by intensity of illumination and value of wind velocity, and then controls opening and closing of pipeline. Gas and water dosing and mixing system includes gas and water mixing unit, which is accordingly equipped with electric contact manometer and solenoid valve. Lower part of gas and water mixing is equipped with multiple systems with rows arranged in parallel. Systems with rows arranged in rows are uniformly equipped with multiple heads for application with grinding, with application of sand for mixing of fertilizers in fluidized bed. Lower end of one side of the gas and water mixing unit is equipped with a control valve and an outlet valve. Control valve is interconnected with the pipeline for gas and water transfer by means of the pipeline. Venturi type fertilizer injector and the pump controlling the communication by the illumination intensity and the wind speed value are located between the control valve and pipeline for gas and water transfer. Venturi type fertilizer injector is communicated with gas and water transfer pipeline by means of connecting pipeline. Control valve is interconnected with the outlet valve by means of the pipeline. Proposed system comprises multicomponent mix controller and gas mixing tank. Inlet end of gas mixing tank is equipped with inlet system with multiple holes. Outlet end of gas mixing tank is equipped with manual outlet valve and electromagnetic outlet valve.

EFFECT: higher yields, higher resistance to diseases and sterilization effect, besides, the device and system are safe, simple and easy to use.
