Description

Technical Field

[0001] The invention relates to soil sampling technology, and in particular to a rotary cutting sampling device for soil environment monitoring. Background Art

[0002] Soil environmental monitoring refers to determining the environmental quality (or pollution level) and its changing trend by measuring the representative values ​​of factors affecting soil environmental quality. The following is a detailed description of soil environmental monitoring:

[0003] 1. Monitoring Purpose

[0004] Assess soil quality: Understand the chemical, physical, biological and other properties of the soil, determine its suitability for use, assess the fertility of the soil, and provide a basis for soil fertility regulation.

[0005] Monitoring soil environmental pollution: timely discover soil pollution problems, take effective control measures, avoid harm to the environment and human health, and provide a scientific basis for soil pollution prevention and control.

[0006] Guide land use planning: understand the characteristics and applicability of soil to provide a basis for scientific and rational land use planning.

[0007] Protect soil resources: help understand the status of soil resources, discover soil problems in a timely manner, take effective measures to protect soil resources, and maintain the ecological environment.

[0008] Promote sustainable development: Provide scientific basis for sustainable development, timely detect soil problems through monitoring, and take corresponding measures to protect soil resources.

[0009] II. Monitoring Project

[0010] my country's "Soil Environmental Quality Standards" stipulates that a total of 11 items should be monitored, including heavy metals, pesticides and pH. The "Technical Specifications for Monitoring Agricultural Soil Environmental Quality" divides soil monitoring items into three categories: mandatory items, optional items and optional items. The optional items include iron, manganese, total potassium, organic matter, total nitrogen, available phosphorus, total phosphorus, water, total arsenic, available boron, fluoride, chloride, mineral oil and total salt content.

[0011] 3. Monitoring methods

[0012] Soil environmental monitoring generally includes technical contents such as sampling, sample preparation, analysis methods, result characterization, data statistics and quality evaluation.

[0013] Point sampling: Point sampling methods include simple random, block random and systematic random. The number of samples must meet the basic requirements of sample capacity and be determined based on factors such as survey purpose, survey accuracy and environmental conditions in the survey area. Sample collection is generally carried out in three stages: preliminary sampling, formal sampling and supplementary sampling.

[0014] Sample processing: The collected soil samples are dried, ground, sieved, etc. to ensure the uniformity and reliability of the samples. For samples with unstable components such as those that are easy to decompose or volatilize, low-temperature storage and transportation methods should be adopted, and they should be sent to the laboratory for analysis and testing as soon as possible.

[0015] Analytical methods: including atomic absorption spectroscopy, spectrophotometry, atomic fluorescence spectrophotometry, gas chromatography, electrochemical method and chemical analysis, etc. Select the appropriate analytical method according to the monitoring indicators.

[0016] 4. Monitoring frequency

[0017] For routine projects, the monitoring frequency can be appropriately reduced based on local conditions, but it must not be less than once every five years. For optional projects, the monitoring frequency can be appropriately increased based on local conditions.

[0018] V. Monitoring Report

[0019] The monitoring report should include the report name, laboratory name, report number, sampling location name, sampling time, analysis time, detection method, monitoring basis, evaluation criteria, monitoring data, single evaluation, overall conclusion, etc. At the same time, it should also include a schematic diagram of the sampling point and information such as the sampler (commissioner), analyst, report preparation, review, audit and issuance and time.

[0020] 6. Notes

[0021] During the sampling process, care should be taken to avoid sample loss, confusion and contamination.

[0022] Light-sensitive samples should be packaged in a light-proof outer packaging.

[0023] Samples should be sent to the laboratory for analysis and testing as soon as possible to ensure the accuracy of the test results.

[0024] In the selection of analytical methods, standard methods (i.e. arbitration methods) should be given priority, and the analytical methods selected in the soil environmental quality standards should be followed.

[0025] In summary, soil environmental monitoring is a complex and important task, which involves multiple links and aspects. Through scientific monitoring methods and strict monitoring procedures, we can better understand the quality of the soil, discover soil problems in a timely manner, and take effective measures to solve them.

[0026] When the existing rotary cutting sampling equipment for soil environmental monitoring is used, it is impossible to accurately collect soil samples of different depths during sampling. If samples of different depths need to be collected, multiple collections are required, which wastes a lot of time and cost. Under the existing technology, if samples of different depths are collected at one time, it is easy for samples of different depths to be mixed together, which is not conducive to subsequent monitoring work.
