Problems solved by technology

[0003] At present, in practical application, according to the soil environment and nutrient content, the technology development of automatic detection, allocation and supply of water and fertilizer is relatively mature, which improves the automation and intelligence of water and fertilizer irrigation to a certain extent; but for crops The control of water and fertilizer requirements in different growth periods mainly depends on the user's on-site inspection and cultivation experience. Even in some application scenarios, this factor has not been paid attention to by managers, resulting in the amount of irrigation water and fertilization obtained by crops in different growth periods. The amount, irrigation time and fertilization time are not optimally controlled
In addition, the existing intelligent water and fertilizer integrated irrigation system does not effectively monitor the physiological health of crops, and cannot reasonably control water and fertilizer irrigation according to the physiological indicators of crops, resulting in large-scale burning and dead seedlings in some crop planting areas. Or the abnormal phenomenon that the plant growth is not as expected

Embodiment 1

[0031] Such as figure 1 As shown, this embodiment considers that the same plant has different water requirements in different growth and development stages, and also has different requirements for various mineral elements such as phosphorus and potassium, and provides an intelligent water and fertilizer integrated sprinkler irrigation system, including a detection subsystem , control subsystem, mixed fertilizer subsystem and sprinkler irrigation subsystem;

[0032] The detection subsystem includes a crop body sensor 110 for collecting physiological information of crops (such as stalk diameter, leaf temperature, chlorophyll content, etc.), a soil moisture sensor 120 for collecting soil water content, and a soil nitrogen and phosphorus sensor for collecting The soil fertility sensor 130 of the potassium content status, the crop body sensor 110 includes a stalk micro-change sensor 111 for collecting the diameter of the crop stalk, and may also include a leaf temperature sensor ar...

Embodiment 2

[0046] Such as figure 2 As shown, the difference between this embodiment and the previous embodiments is that in this embodiment, the high-efficiency cooperation between the sprinkler irrigation subsystem and the control subsystem is emphasized, that is, the optimization of control performance, and the use of solid water-soluble fertilizers and the possibility of the ratio of various element fertilizers are also considered. Denaturation; the crop body sensor 110 also includes a fruit expansion sensor 112, some crops have larger fruits in the mature stage, and the fruit expansion sensor 112 is only set on a certain fruit of the crop during the mature stage, and can be used for real-time collection of crop maturity. When the first receiving module 110 receives the data from the fruit expansion sensor 112, it means that the crop is currently in the mature stage. According to the change in the diameter of the fruit before and after the fruit, it can be refined and analyzed to dete...

Embodiment 3

[0056] Such as image 3 As shown, the difference between this embodiment and Embodiment 2 is that the fertilizer mixing device of this embodiment is suitable for irrigation of liquid fertilizers; the fertilizer mixing device includes a mother liquor tank 330, a venturi tube 340 and a fertilizer mixing pipeline 350, and The inlet of the fertilizer liquid at the venturi tube 340 throat is communicated with the mother liquid tank 330 through a pipeline, the inlet of the venturi tube 340 is communicated with the water supply pipe, and the outlet of the venturi tube 340 is connected with the inlet of the mixed fertilizer pipeline 350 connected, the outlet of the mixed fertilizer pipeline 350 communicates with the sprinkler irrigation subsystem and is provided with an EC probe 6, a second liquid flow meter 8 and a fifth solenoid valve, and the control subsystem is provided with a second receiving module 240 for use in In order to receive the information of the EC probe 6 and the sec...

Abstract

The invention relates to the technical field of irrigation, and discloses an intelligent sprinkling irrigation system with integration of water and fertilizer and a control method thereof. The systemcomprises a detection sub-system, a control sub-system, a fertilizer mixing sub-system and an irrigation sub-system, wherein the detection sub-system comprises a crop body sensor, a soil moisture content sensor and a soil fertility sensor; the control sub-system comprises a first receiving module, a calculation module and a comparison prewarning module; and the fertilizer mixing sub-system comprises a fertilizer mixing device. The method comprises the steps of system debugging preparation, information collection, actual demand calculation, water-fertilizer proportioning and irrigation. According to the system and method, the growing period of crops can be actively analyzed, fertilization and irrigation are provided by combining the regulation of water and fertilizer requirement of crops indifferent growing periods, abnormal growth of crops can be actively found, and administrative staff is informed; and after long time of use, pipelines of the irrigation sub-system are not easily blocked, the content of nitrogen, phosphorus and potassium of liquid remained after irrigation can be tracked, and reclaimed residual liquid does not need independent treatment during recycling, so that recycling can be convenient.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to an intelligent water and fertilizer integrated sprinkler irrigation system and a control method. Background technique [0002] The water and fertilizer integration technology uses the existing water-saving irrigation system, uses the water of the system as the carrier, and at the same time irrigates the water, and at the same time, the fertilizer is blended into a fertilizer solution by an intelligent fertilizer applicator and transported to the soil in the root zone of the crops, so that it can be directly absorbed by the crops. Absorption; At present, it is widely used in the fertilization and irrigation of fruit forests, vegetables, flowers and other field agricultural crops. Residues, alleviate water pollution, in addition, can also save manpower and material resources, increase income. Intelligent water and fertilizer integrated irrigation uses computer technology on the...
