Abstract

The invention relates to a movable micro-sprinkling irrigation water-fertilizer integrated comprehensive management system and a control method thereof. The system comprises a movable device, a micro-sprinkling belt spreading/rolling device, a precision fertilizer preparation device, a head hub device, a control system and a power supply source, wherein the movable device comprises an electric tricycle and a movable bracket; the micro-sprinkling belt spreading/rolling device is used for paving and rolling a micro-sprinkling belt; the precision fertilizer preparation device is used for precisely ejecting fertilizer and preparing a concentration-controllable mother liquor; the head hub device is an integration of equipment for pressurization, adjustment, control, purification, fertilization, detection and the like and is used for conveying the irrigation water and fertilizer mother liquor; and the control system is used for controlling accurate operation of the micro-sprinkling belt spreading/rolling device, the precision fertilizer preparation device and the head hub device. According to the invention, the fertilizer can be automatically prepared, the ejection and preparation of mother liquor are realized at the same time, the working continuity of the device is improved, and the time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of farmland water and fertilizer integration, in particular to a mobile micro-sprinkler irrigation water and fertilizer integrated comprehensive management system and its control method, which are used for laying and rewinding of micro-spray belts for field crops such as wheat and corn, and online refining of multi-fertilizers. Quantitative fertilizer distribution, micro-sprinkler irrigation and integrated operation of water and fertilizer. Background technique [0002] Water and fertilizer integrated micro-sprinkler irrigation technology is a new agricultural technology that integrates micro-sprinkler irrigation and fertilization. Water and fertilizer integrated micro-sprinkler irrigation is to use the pressure system to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop species. The fertilizer solution and irrigatio...

AI Technical Summary

Problems solved by technology

[0004] 1. When the water and fertilizer integration technology of micro-sprinkler irrigation is applied to field crops, it is necessary to lay the micro-spray belt after the crops are sown, and roll up the micro-spray belt before harvesting. The labor cost is high, the efficiency is low, and it is difficult to promote in a large area;

[0005] 2. The working pressure and flow of the micro-spray irrigation water source are easy to fluctuate and unstable, resulting in unstable irrigation uniformity and irrigation volume;

[0006] 3. Although the micro-sprinkler irrigation system is equipped with fertilization equipment such as Venturi fertilizer injector or proportional fertilizer suction device, it is difficult to achieve precise control of fertilization when the water pressure is unstable, and there are many operating procedures, farmers are generally unwilling to use it;

[0007] 4. The granular fertilizers used by farmers are prone to incomplete dissolution, which can easily cause clogging of the filter of the micro-sprinkler irrigation system. Water-soluble fertilizers are expensive and difficult for farmers to accept

[0008] In summary, according to the characteristics of decentralized management of field production plots, in view of the problems of time-consuming and labor-intensive laying of micro-spray belts, inaccurate fertilizer ratios, high input costs of water and fertilizer integration systems, low use efficiency, and inability to flexibly apply to different fields, etc., There is an urgent need to invent a mobile micro-sprinkler irrigation water and fertilizer integrated management system and its control method, which is used for the placement and rewinding of micro-spray belts for wheat, corn and other field crops, the online precision distribution of multi-fertilizers, and the integration of micro-spray irrigation water and fertilizer. operation, which has important practical significance for improving the efficiency of water and fertilizer integration and increasing grain production
