Embodiment 1

[0059] Embodiment 1: tomato planting embodiment

[0060] Taking the medium-early-maturing tomato Rising No. 5 as an example, the planting mode of overwintering stubble under the condition of solar greenhouse was selected, and the irrigation method was drip irrigation. Enter the planting date 9.28, the soil texture is light loam, and the target yield is set to 10000kg / mu. The system automatically generates irrigation and fertilization schemes, as attached image 3 As shown, when the scheduled irrigation and fertilization time is reached, the real-time information collected by the sensor is used to adjust the irrigation water volume and formula, and the batching, fertilizer injection, and irrigation and fertilization are all automatically completed without human participation.

Embodiment 2

[0061] Embodiment 2: application embodiment in orchard apple plot planting

[0062] An orchard is planted with 5 apples, variety Red Fuji, 5-year-old trees, with a land area of ​​3 mu and a target output of 4000 kg; the irrigation and fertilization plan is automatically generated, as shown in the attached image 3 As shown, when the scheduled irrigation and fertilization time is reached, the real-time information collected by the sensor is used to adjust the irrigation water volume and formula, and the batching, fertilizer injection, and irrigation and fertilization are all automatically completed without human participation.

Abstract

The invention provides an intelligent precise fertigation device with real-time nutrient proportioning and a control method. The device comprises a user operation unit, a fertilization scheme generating unit, a sensor data collection unit, an intelligent fertilizer preparation unit and a water-fertilizer integral irrigation unit, wherein the user operation unit is a touch control screen and can beused for account registering login; after the login is successful, a user selects or inputs basic information such as the geographic position, soil property, crop types, crop varieties, plant date, land parcel area, irrigation modes and target yield; the site irrigation data can be displayed and checked; the automatic irrigation in turns of different crops in a plurality of land parcels can be completed through real-time fertilizer proportioning. The nutrient real-time proportioning according to different crop types, different crop production periods and soil nutrient contents can be realized; the precise fertilization is realized; the water and the fertilizer are saved; the time and the labor are saved; the fertigation efficiency is improved; good growth environment is provided for crops.

Description

technical field [0001] The application relates to the field of intelligent agricultural irrigation technology, in particular to an intelligent precision irrigation and fertilization device and control method for realizing real-time ratio of nutrients. Background technique [0002] At present, water and fertilizer integration technology is widely used in various aspects such as orchards, greenhouses, fields and greening at home and abroad. Domestic water and fertilizer integration equipment generally uses common chemical fertilizers and water-soluble fertilizers as raw materials for water and fertilizer integration equipment. According to the experience of growers, the ratio of water and fertilizer is carried out to complete the integration of water and fertilizer irrigation. The main problems are that the formula of the finished chemical fertilizer is suitable for different regions, and its formula is relatively compromised and popular. It is not suitable for flexibly contro...
