Intelligent precise fertigation device with real-time nutrient proportioning and control method

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...

AI Technical Summary

Problems solved by technology

The authorized announcement number is CN 103548463 B, which provides a precision irrigation and fertilization system. The precision control of various elements is realized by increasing or decreasing the stock solution tank and the corresponding number of proportional fertilization pumps. How to determine the specific formula, this system does not It cannot be realized, and fertilization through this system needs to mix the original solution into the mixing tank. Such a fertilizer distribution can only be used for irrigation of one crop, and the fertilizer needs to be re-distributed when changing crops.
