Embodiment 1

[0020] Embodiment 1. When all farmland needs to be irrigated and the fertilizer injector is a Venturi fertilizer injector or a proportional fertilizer injector, start the head system 1, and first open the first block closest to the head system 1 The irrigation valve 8 corresponding to the farmland, the water at the water source passes through the main water delivery pipe 5 and enters the sub-water delivery pipe 6 under the action of the head system 1, and at the same time, the fertilizer liquid medicine in the fertilizer supply system 3 passes through the main fertilizer delivery pipe 4 enters the distribution fertilizer delivery pipe 9, then enters the distribution water delivery pipe 6 through the fertilizer injection system 7, and enters the field after mixing evenly with the water in the distribution water delivery pipe 6. When the first farmland meets the irrigation demand, close the irrigation valve 8 corresponding to the first farmland, then open the irrigation valve 8 c...

Embodiment 2

[0021] Embodiment 2. When all farmland needs to be irrigated and the fertilizer injection injector is a differential pressure fertilizer injection injector or an elbow bypass type fertilizer injection injector, start the head system 1, and first open the head system 1 The irrigation valve 8 corresponding to the nearest first piece of farmland, the water at the water source passes through the main water pipe 5 and enters the water distribution pipe 6 under the action of the head system 1, and at the same time, the fertilizer and medicine storage tank in the fertilizer injection system 7 will be evenly distributed. The fertilizer solution is poured into the water distribution pipe 6, mixed evenly with the water in the water distribution pipe 6, and enters the field. After irrigation, the fertilizer and drug supply system 3 is used to add the fertilizer and drug liquid to the fertilizer and drug storage tank. When the first farmland meets the irrigation demand, close the irrigatio...

Embodiment 3

[0022] Embodiment 3, when the water demand of each farmland is different, some need to be irrigated, some do not need to be irrigated, and when the fertilizer injector is a Venturi injector or proportional fertilizer injector, start the first system 1, Open the irrigation valve 8 corresponding to the farmland that needs to be irrigated. The water at the water source passes through the main water delivery pipe 5 and enters the sub-water delivery pipe 6 under the action of the head system 1. At the same time, the fertilizer liquid in the fertilizer supply system 3 passes through The total fertilizer delivery pipe 4 enters the distribution fertilizer delivery pipe 9, then enters the distribution water delivery pipe 6 through the fertilizer injection system 7, and enters the field after being mixed evenly with the water in the distribution delivery pipe 6. When this farmland meets the irrigation demand, close the irrigation valve 8 corresponding to this farmland, and then open the ...

Abstract

A big field micro-irrigation distributed type precise fertilizer-applying pesticide-applying device is additionally provided with fertilizer-injection pesticide-injection systems and a fertilizer-supplying pesticide-supplying pipeline; an irrigation valve is additionally arranged on each branched water delivery pipe; a fertilizer-supplying pesticide-supplying system is communicated with a head system; the fertilizer-supplying pesticide-supplying pipeline comprises a total fertilizer-delivery pesticide-delivery pipe communicated with the fertilizer-supplying pesticide-supplying system, and branched fertilizer-delivery pesticide-delivery pipes communicated with the total fertilizer-delivery pesticide-delivery pipe; one end of each fertilizer-injection pesticide-injection system is communicated with the branched fertilizer-delivery pesticide-delivery pipe, and the other end of each fertilizer-injection pesticide-injection system is communicated with an inlet of each irrigation valve. With adopting of the mode of separate delivery of water, a fertilizer liquid and a pesticide liquid, the corresponding irrigation valves are opened according to the actual needs in the field irrigation, the fertilizer-injection pesticide-injection systems can inject the fertilizer liquid and the pesticide liquid together with water into the branched water delivery pipes, allows the fertilizer liquid, the drug liquid and water to be mixed into a whole and then be irrigated into a field, the practicability is strong, the cost is low, installation and operation are simple, and the problem of uneven fertilizer application of large-area farmland is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural water-saving irrigation, and relates to a field micro-irrigation distributed precise fertilization and drug application device. Background technique [0002] Integrated fertilization and irrigation of water and fertilizer and integrated pesticide application of water and medicine are an important feature of micro-irrigation. For large-scale farmland fertilization and pesticide application, from the perspective of modern agricultural production, centralized fertilization and pesticide application are generally adopted, that is, micro-irrigation system The first part mixes fertilizers and pesticides into irrigation water, and transports them to the field along with the irrigation pipe network. In actual production, in order to reduce the cost of the micro-irrigation system, farmers open the valves dispersedly during irrigation rotation, and reduce the diameter of the pipe network by dispersing ...
