Fine crop information monitoring device and crop information monitoring system and analysis method based on device

Abstract

The invention discloses a fine crop information monitoring device.The fine crop information monitoring device comprises a collecting bucket, an automatic spraying device for flushing, collecting and automatically cleaning a sample in the collecting bucket, an ultrasonic wave extraction device with a built-in piezoelectric transducer, a two-stage dry and wet deposition sample filtering and collecting device, an automatic sampling device, an ion chromatography analyzer, a PH value and electric conductance value analysis device, an online positive and negative ion analysis system and a display device.The invention further discloses a crop information monitoring system based on the device and a crop information analysis method.The crop information monitoring device utilizes the ion chromatography analyzer to conduct accurate analysis on positive and negative ions in soil.For establishing a food safety system in agricultural production, the fine crop information monitoring system provides an intelligent agricultural information sensing and tracing system.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a crop information monitoring device in the field, a crop information monitoring system and a crop information analysis method based on the device. Background technique [0002] Internationally, the European Union, the United States and other developed countries and regions require that some foods exported to the local area must have traceability requirements, otherwise they will not be allowed to be sold on the market. The food quality and safety traceability system established by developed countries, in addition to effectively ensuring food safety and hygiene and traceability, has become increasingly prominent as a trade barrier. It can be seen that the establishment of a traceability system for agricultural products in my country can not only provide high-quality and safe agricultural products for the people's dietary health, but also an important means to break the trad...

Problems solved by technology

[0003] (1) At present, the domestic tracking system is not perfect enough. It simply records the origin of crops, crop types and other information, and fails to form a complete tracking system from planting, growth, picking, sales to consumption.

[0004] (2) Ion chromatography is mainly used for the analysis of environmental samples, including anions and cations in samples such as surface water, drinking water, rainwater, domestic sewage and industrial wastewater, acid deposits and atmospheric particles, and water and cations related to the microelectronics industry. The analysis of trace impurities in reagents is also widely used in the fields of food, hygiene, petrochemical, water and geology, but has not been used in the detection of agricultural ecological environment
