Embodiment 1

[0024] See figure 1 , the present invention discloses an irrigation and fertilization system controlled by fertilizer and water lines, including a water supply pipeline, a fertilizer supply pipeline, and an air supply pipeline; The water supply pipe 4; the fertilizer supply pipeline includes a fertilizer supply device 2, and the fertilizer supply device 2 is connected to the fertilizer supply supervisor, and the fertilizer supply supervisor is provided with a fertilizer supply pipe 5. The invention supplies water and fertilizer in separate lines, so that different users can more flexibly control the time and amount of irrigation and fertilization, and apply different fertilizers without uniform irrigation and fertilization.

[0025] See figure 1 with figure 2 , the gas supply pipeline includes a gas source device 3, the gas source device 3 is connected to the gas supply main pipe, the gas supply main pipe is provided with an air supply branch pipe 6, the air supply branch p...

Embodiment 2

[0037] Unified management plus personalized management mode

[0038] In conjunction with Example 1, such as Figure 1-3 As shown, in this embodiment, the present invention is applicable to large-scale agricultural parks, which not only have the situation of unified management of fertilization and irrigation, but also have the phenomenon of individualized fertilization and pesticide spraying. This type of agricultural park leads to a plurality of personalized and independently operated greenhouses with different plants through a plurality of side-by-side field branch pipes 9 and field facilities connected thereto. It can not only carry out conventional and uniform sprinkler irrigation, drip irrigation, and fertilization, but also carry out individualized additional fertilization and pesticide spraying. Under this kind of working mode, the fertilizer used for uniform irrigation and fertigation is uniformly prepared in the fertilizer supply device 2, and the fertilizer that need...

Embodiment 3

[0045] Fully Personalized Management Mode

[0046] In conjunction with Example 1, such as Figure 1-3 As shown, this embodiment is suitable for parks where individualized management of different contractors is the main focus, and unified fertilization is not considered, and the fertilizer supply pipeline, fertilizer supply management 5 and fertilizer supply device 2 are canceled or closed.

[0047] User Zhang San needs to implement micro-spray irrigation, and the specific implementation steps are shown in Example 2.

[0048] User Li Si needs to implement micro-spray fertilization. While Zhang San uses micro-spray irrigation, Li Si brings the batching bucket 7 and connects the air control valve 22 and liquid control valve 801 installed on the air supply branch 6 of his greenhouse. between, and pour the fertilizer into the batching bucket 7 to dissolve and mix, open the liquid control valve 801, the water control valve 13, the micro-spray control valve 21, and keep the fertil...

Abstract

The present invention provides an irrigation and fertilization system with fertilizer and water line control. The system includes three sets of pipelines for water supply, fertilizer supply and air supply, wherein the fertilizer supply pipeline includes a fertilizer supply device connected to a fertilizer supply supervisor, which There are fertilizer supply pipes on it. The gas supply pipeline includes a gas source device, which is connected to the main gas supply pipe, and the main gas supply pipe is provided with a gas supply branch pipe, which is connected to the top of the batching tank, and the batching branch pipe is inserted into the batching tank; the batching branch pipe and the water supply pipe , and the fertilizer supply pipes converge in the field branch pipes, and the field branch pipes lead to the field facilities. The field facilities include drip irrigation branch pipes, water spray spray branch pipes, and micro-spray branch pipes. The invention can not only meet the requirements of unified irrigation and fertilization in modern agricultural parks, but also meet the individual application requirements in the parks, so that different users can more flexibly control the period and amount of irrigation and fertilization according to the characteristics of water and fertilizer requirements of different crops and different growth stages of crops , apply different fertilizers, and can be applied at the top of the field.

Description

technical field [0001] The invention relates to an irrigation and fertilization system controlled by fertilizer and moisture lines for agriculture, belonging to the field of agricultural irrigation machinery and equipment. Background technique [0002] With the continuous increase of national funds in agricultural investment, irrigation and fertilization facilities have developed on a large scale, and a large number of large-scale and well-equipped agricultural modernization parks have been built to achieve unified irrigation and fertilization. However, due to the agricultural production of most parks It is still dominated by contract management, and unified irrigation and fertigation is difficult to meet the irrigation and fertigation needs of different operators, especially fertilization, because the fertilizer requirements and management methods of different operators, different crop varieties, and crops at different growth stages are inconsistent, resulting in It is diff...
