Embodiment 1

[0034] A sprinkler irrigation system for greenhouse crop production. When the greenhouse crops are planted, the existing mature comprehensive management control technology is used to realize the facility and equipment management control of the sprinkler irrigation system. Through the comprehensive management of the supervisory system and fertilizer applicators, the fertilizer applicators can be automated. Load the fertilizer into the main system, and then apply water and fertilizer to the crops in the greenhouse planting area through the nozzle system, so that the crops can get the required water and fertilizer, and achieve intelligent greenhouse crop planting management, such as figure 1 As shown, the following arrangement structure is adopted in particular: a controller 15, a fertilizer applicator 7, a main pipe system and a nozzle system are provided, the fertilizer applicator 7 is connected to the main pipe system, and the main pipe system is connected to the nozzle system. ...

Embodiment 2

[0037] This embodiment is further optimized on the basis of the above embodiments. Further, in order to better realize the present invention, multiple nozzles can be used to apply water and fertilizer to the greenhouse crops, and the water pressure can be adjusted through a pressure regulator, so that when the sprinkler irrigation is performed It will not cause over-irrigation or under-irrigation due to unstable water pressure, which will affect the growth period of crops, such as figure 1 As shown, the following arrangement structure is particularly adopted: at least two spray heads 19 are evenly arranged on the spray pipe 20, and the pressure regulator 18 is arranged between the first spray head 19 near the connection of the main pipe system and the main pipe system .

[0038] When designing and using, a plurality of nozzles 19 are evenly arranged on the shower pipe 20, and the setting of the nozzles 19 can be flexibly adjusted according to the spraying area, and the pressur...

Embodiment 3

[0040] This embodiment is further optimized on the basis of any of the above-mentioned embodiments. Further, in order to better realize the present invention, water and fertilizer can be mixed in the main pipe system, and the fertilizer that has not been fully mixed will be retained to avoid pipe blockage or partial If the amount of fertilizer is too high, the situation of burning seedlings occurs, and the waterway can be switched on and off based on the electric switch of the waterway channel, such as figure 1 As shown, the following arrangement structure is adopted in particular: the main pipe system is provided with a water and fertilizer mixing area 6 and a filter 11, the fertilizer applicator 7 is connected with the water and fertilizer mixing area 6, and the fertilizer applicator 7 is arranged in the water and fertilizer mixing area 6 above; the outlet of the water and fertilizer mixing zone 6 is connected with the inlet of the filter 11 through a pipe, the outlet of the ...

Abstract

The invention discloses a sprinkling irrigation system for greenhouse crop production. The system is provided with a controller, a fertilizer device, a main pipe system and a spray pipe system, wherein the fertilizer device is connected to the main pipe system which is connected with the spray pipe system and the controller is connected with the main pipe system and the fertilizer device respectively. The spray pipe system is provided with a spray pipe, a pressure regulator and a sprayer, wherein the spray pipe is connected to the main pipe system, the sprayer and the pressure regulator are arranged on the spray pipe, and the pressure regulator is arranged on the position close to the connection part of the main pipe system. When greenhouse crops are planted, management control of the facilities and devices of the sprinkling irrigation system is achieved through an existing proven comprehensive management control technology; the main pipe system and the fertilizer device are managed comprehensively, so that the fertilizer device can load automatically fertilizers in the main pipe system, and then conduct irrigation and fertilization on the crops in a greenhouse region, so that the crops can obtain the required water and fertilizers.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a sprinkler irrigation system for greenhouse crop production. Background technique [0002] Greenhouses, with the emergence of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan, European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used to cover vegetables in small sheds in Beijing, and achieved the effect of early maturity and increased production. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, greenhouses have been used for potted flower and cut ...
