Embodiment 1

[0050] This embodiment provides a method for quick diagnosis of irrigation, including:

[0051] S101. Preset the current average moisture content model of the root zone and the reference crop water demand ET in a certain area 0 The forecast model and a series of corresponding parameters are stored in the parameter database. The specific sub-steps are described as follows:

[0052] S1011. Preset a series of parameters of a certain region in the parameter database.

[0053] It should be noted that each parameter in the parameter database represents the characteristics of crops, soil, weather and other factors in a certain area. Due to different geographical conditions in each region, there are one or more parameter databases preset in the device. Each parameter database is named after a representative weather station in a certain area.

[0054] Among them, the parameters contained in the parameter database are:

[0055] a) Crop parameters: including the main crop types in t...

Embodiment 2

[0166] This example takes the irrigation diagnosis of spring corn in a plot in Tongzhou, Beijing as an example. It is assumed that the sowing time is May 1, and the diagnosis time is May 15. The latitude and longitude coordinates of the plot are 39.80°N, 116.68°E, The soil is loam, the irrigation method is drip irrigation, and the surface soil (0-10cm) volume moisture content is 18%. It is the first time for the user to perform irrigation diagnosis on this plot.

[0167] Firstly, the irrigation wizard starts to run. According to the coordinate information of the plot automatically detected, the program compares it with the coordinates of each weather station. The nearest weather station is "Beijing", and the program calls the parameter database named after "Beijing" preset in the device. and related parameters.

[0168] The user selects the initial diagnosis according to the prompts, creates a new plot information, enters the plot name "01", selects the crop "spring corn", se...

Embodiment 3

[0191] Such as figure 1 As shown, the rapid irrigation diagnosis device provided in this embodiment includes: a host computer 1 and a soil data collector 2 .

[0192] The number of soil data collectors 2 is one, preferably a probe-type time-domain reflection sensor or a frequency-domain reflection sensor that is convenient to insert into the soil, and collects the volume moisture content θ of the planned wetting layer during irrigation diagnosis s . The sensors described above use the dielectric principle to detect the moisture status of the soil. The soil data collector 2 is preferably connected to the host computer 1 through cables and aviation plugs.

[0193] Wherein preferably, the host 1 is provided with a SIM card slot 14 outside, a mobile phone SIM card is installed in the SIM card slot 14 and the mobile network service is opened by the operator, so that the host can obtain data through the mobile network; The power switch 16 on 1 is used to control the opening or cl...

Abstract

The invention provides an intelligent device and a method for irrigation rapid diagnosis. The irrigation rapid diagnosis method comprises: obtaining soil moisture data, obtaining weather data of the land on the day and in a forecast period, obtaining information of crops, and types of soil; according to the information of crops, the soil moisture data, the types of soil, and weather data, calculating irrigation lower limit rate of the crops and root zone average moisture content in each forecast day in the forecast period, analyzing and comparing the root zone average moisture content and the irrigation lower limit rate, to generate an irrigation suggestion; and showing the irrigation suggestion. Compared with an existing irrigation rapid diagnosis device, the provided diagnosis method is aimed at conditions of different crops in different regions, and gives comprehensive consideration to weather factors and actual water consumption characteristics, and provides relatively scientific and rational irrigation suggestion, so as to overcome defects of irrigating by manual experience to a certain extent.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to an irrigation rapid diagnosis device and method. Background technique [0002] my country's water resources are severe, and water problems seriously restrict my country's agricultural production and rural development. Among agricultural water use, farmland irrigation water accounts for more than 90% of it. Therefore, the development of water-saving irrigation is an important measure to promote the sustainable use of water resources in my country and ensure the sustainable development of agriculture. However, in the practice of agricultural production, farmers are affected by traditional consciousness, and the problems of irrigation management based on experience and subjective human factors are more prominent. The irrigation management method can neither meet the requirements of water-saving irrigation technology, nor can it effectively guarantee crop demand. , re...
