Embodiment 1

[0026] Such as figure 1 As shown, Embodiment 1 provides a greenhouse water and fertilizer irrigation system, which includes a water inlet pipe 1, an irrigation switch pipe 2, an indoor main pipe 3, a micro-spray belt 4, a switch control cabinet 8, and a drainage pipe 9.

[0027] The water inlet end of the water inlet pipeline 1 is connected with a water well shared by multiple greenhouses or a main water supply pipeline. The water outlet end of the water inlet pipe 1 is connected with the water inlet end of the irrigation switch pipe 2, and the water outlet end of the irrigation switch pipe 2 is connected with the water inlet end of the indoor main pipe 3.

[0028] Wherein, the irrigation switch pipeline 2 includes a mechanical switch pipeline 21 , an electromagnetic valve switch pipeline 22 , a first switch 23 and a second switch 24 . The mechanical switch pipeline 21 and the electromagnetic valve switch pipeline 22 are connected in parallel between the water outlet end of t...

Embodiment 2

[0036] Such as figure 1 As shown, the greenhouse water and fertilizer irrigation system provided by embodiment 2 has basically the same structure as that of embodiment 1, the difference is that the greenhouse water and fertilizer irrigation system also includes a fertilizer suction device 5 and a fertilizer bucket 6, and the fertilizer suction device 5 is connected in series It is located between the irrigation switch pipeline 2 and the indoor main pipeline 3 , and the fertilizer suction device 5 and the fertilizer bucket 6 can be connected through a hose 55 . Fertilizer 5 adopts commonly used on the existing market and gets final product. For example, the fertilizer suction device 5 includes a water pipe 51 and a fertilizer suction pipe 52, and the water pipe 51 and the fertilizer suction pipe 52 are connected in parallel between the irrigation switch pipeline 2 and the indoor main pipeline 3, and a third switch is arranged in the middle section of the water pipe 51. 53, the...

Embodiment 3

[0040] Such as figure 1 As shown, the greenhouse water and fertilizer irrigation system provided by embodiment 3 has basically the same structure as that of embodiment 2, except that the greenhouse water and fertilizer irrigation system also includes a filter 7, which is connected in series between the fertilizer absorber 5 and the indoor Between the main pipes 3. Filter 7 adopts existing product in the market, by filter 7, avoids that the impurity that enters from fertilizer tank 6 places enters indoor main pipe 3, and then enters micro-spray belt 4, stops up micro-spray belt 4 or micro-spray hole 41.

[0041] The "connection" in the above three embodiments can be connected by ordinary pipe joints. Where there is parallel connection, it can be connected by three-way or four-way joints, or in the form of a combination of three-way and four-way. Pipeline connection and sealing All belong to the prior art, and will not be described in detail here.

Abstract

The embodiment of the invention discloses a greenhouse water-and-fertilizer irrigation system, and relates to the technical field of agricultural irrigation. The greenhouse water-and-fertilizer irrigation system comprises a water inlet pipeline, an irrigation switch pipeline, an indoor main pipeline and multiple micro-spraying belts; the water outlet end of the water inlet pipeline is connected with the water inlet end of the irrigation switch pipeline, the water outlet end of the irrigation switch pipeline is connected with the water inlet end of the indoor main pipeline, the micro-spraying belts are arranged at equal intervals in the length direction of the indoor main pipeline, and all located at the same side of the indoor main pipeline, and multiple micro-spraying holes are formed inthe pipe bodies of the micro-spraying belts, and formed at equal intervals in the length direction of the micro-spraying belts. By means of the greenhouse water-and-fertilizer irrigation system, irrigation can be more uniform, the water, fertilizer and labor can also be saved, and the temperature and humidity can be controlled at the same time.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of agricultural irrigation, in particular to a greenhouse water and fertilizer irrigation system. Background technique [0002] A greenhouse, also known as a greenhouse, is a facility that can transmit light, keep warm (or heat), and be used to grow plants. In seasons that are not suitable for plant growth, the greenhouse can provide a growth period and increase production, and is mostly used for cultivation or seedling cultivation of temperature-loving vegetables, flowers, forest trees and other plants in low temperature seasons. [0003] At present, the greenhouse irrigation mode is water supply from wells, and the soil in the greenhouse is flooded with water through the main pipeline. Specifically, the water well is generally located on the west side of the inner side of the greenhouse. On the north wall of the greenhouse, a water channel about 0.6m wide is built with cement, sa...
