Embodiment 1

[0048] In the present embodiment, the technical scheme is suitable for irrigation and fertilization of dryland plants with shallow roots, and specifically includes as follows:

[0049] A water and fertilizer integrated four-control irrigation and fertigation system, including an irrigation and fertigation controller and irrigation and fertigation equipment located in the irrigation and fertigation area, characterized in that the irrigation and fertilization area is equipped with a soil moisture sensor in the plant root-intensive area or the largest root-soil functional area ; The controller is connected to the soil moisture sensor and controls the water outlet valve according to the collected data. This kind is applicable to the plant irrigation and fertilization of shallow root system, and specific embodiment is as follows figure 1 with figure 2 Only one soil moisture sensor is set in the system.

Embodiment 2

[0051] The technical scheme in this embodiment is suitable for irrigation and fertilization of dry land plants with deeper roots, specifically including as follows:

[0052] A water and fertilizer integrated four-control irrigation and fertilization system, including a middle-layer soil moisture sensor and a bottom-layer soil moisture sensor arranged in the middle of the plant root-intensive area or the largest root-soil function area, and the controller is connected to the middle-layer soil moisture sensor and the bottom-layer soil moisture sensor.

[0053] The controller is equipped with a time control module, a fertilizer amount control module, a nutrient ratio control module, and a soil humidity control module based on the four-control irrigation and fertilization system;

[0054] The time control module is used to control the period of fertigation and the duration of each fertigation;

[0055] Fertilization amount control module, used to control the total amount of fertiliz...

Embodiment 3

[0079] The technical solution of this embodiment is applicable to the integrated irrigation and fertigation of rice cultivation, and the system of this embodiment ( image 3 ) mainly consists of fertilizer supply pump 3-1, fertilizer bucket 3-2, flow rate meter 3-3a, speed control valve 3-3b, fertilizer supply pipe 3-4, flow meter 3-5, manual valve 3-6, solenoid valve 3-7, time controller 3-8, water outlet 3-9, mixing impeller 3-10, water supply channel 3-11, water level gauge 3-12.

[0080] The technical solution of this embodiment is realized by the following steps:

[0081] 1. During the implementation of the technical scheme of this embodiment, the fertilizer solution was pumped from the fertilizer tank 3-2 to the field water outlet 3-9 through the pipeline system by the fertilizer pump 3-1, and flowed to the field with the irrigation water coming from the channel 3-11 . When the irrigation water and fertilizer liquid flow through the field water discharge channel, they ...

Abstract

The invention discloses a water-fertilizer-integrated four-control irrigating and fertilizing system. The system comprises middle-level soil moisture sensors and bottom-level soil moisture sensors, which are arranged in dense root areas of plants or middle parts of maximum root soil functional areas, wherein a controller is connected with the middle-level soil moisture sensors and the bottom-level soil moisture sensors. According to the system, the operation is easy, labor is saved, and the popularization and application are facilitated; accurate fertilizer application is achieved through scientifically formulating the total amount of fertilizer application according to the nutrient requirements of crops and regulating and controlling the amount of applied fertilizer through methods such as metered fertilizer application, concentration control, designed irrigation and fertilizer application frequency and proportional fertilizer applicator application, and equipment, and irrigation and fertilizer application control is carried out according to water and fertilizer requirement rules of the crops, so that the crops can be good in growth, high and stable yield is achieved, environmental pollution caused by excessive irrigation and fertilizer application can be controlled, and thus, the irrigation and fertilizer application of comprehensive and accurate control on the period and duration of irrigation and fertilizer application, the total amount and single usage amount of fertilizer application, the degree and depth of irrigation humidification and the concentration and nutrient proportion of fertilizer and water are truly achieved.

Description

technical field [0001] The invention relates to the technical field of water and fertilizer integration, in particular to a water and fertilizer integrated irrigation and fertilization control system. Background technique [0002] Water and fertilizer integration technology is the development direction of modern agriculture and an important means of precise fertilization. According to different environmental conditions and crop water and fertilizer demand rules, using scientific and reasonable control methods to implement water and fertilizer integration is the only way to achieve efficient irrigation and fertilization. However, since the water and fertilizer integration technology has not been used for a long time in China, people generally lack both application experience and in-depth research on the application technology. When implementing the water and fertilizer integration technology, how to control irrigation and fertilization is still lacking. And the method with st...
