Description

TECHNICAL FIELD

[0001] The present application relates to a kind of base ecological environment fixed point monitoring point layout method of wine sorghum production, belong to environmental monitoring technical field. BACKGROUND

[0002] The ecological climate environment of agricultural product origin is closely related to crop yield and quality, and excellent origin ecological environment is the basis for high-yield, high-quality and efficient production of crops. Domestic famous geographical indication products are produced in their special and excellent origin ecological environment.

[0003] Sorghum is a plant of the genus Sorghum in the family Poaceae, and is an important raw material for the wine industry. The quality of sorghum is influenced by various environmental and ecological factors such as climate, soil, altitude, and biology in addition to the genetic control of the variety itself. Based on the investigation of the sorghum base topography data, this study provides a reference for the related research on high-quality sorghum and optimized planting layout, which is of great significance for promoting the high-quality development of Guizhou wine industry.

[0004] Currently, the investigation and monitoring of origin ecological environment mainly focuses on climate and soil conditions, while the monitoring of topography is relatively less. This monitoring mode has obvious limitations, especially in mountainous and hilly areas, where the influence of topography on ecological environment is extremely significant, but it has not been fully incorporated into the monitoring system. In addition, the existing monitoring design mainly studies climate, soil, and topography in isolation, and there is a lack of monitoring design reports that comprehensively consider these factors. This isolated monitoring method cannot fully reflect the complexity and interaction of ecological environment, and it is difficult to reveal the correlation between sorghum yield and the main comprehensive ecological environment of the origin. Therefore, the selection of ecological environment monitoring points often lacks representativeness, and it is difficult to accurately assess the true ecological conditions of sorghum origin. Unreasonable point selection leads to the fact that the monitoring data cannot fully reflect the ecological environment characteristics of the entire origin, which further affects the accurate judgment of the correlation between sorghum yield and ecological environment.

[0005] Therefore, it is urgent to improve the selection method of monitoring points, increase the monitoring of topography, and comprehensively consider climate, soil, and topography to more comprehensively evaluate the ecological environment of sorghum origin, thereby providing a scientific basis for the improvement of sorghum yield.

[0040] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail with reference to the drawings.

[0041] Embodiment one:

[0042] The present embodiment provides a method for laying out the monitoring points of the ecological environment of the sorghum production base, referring to Figure 1 , the method comprises:

[0043] Step 1: Collecting image data related to the sorghum production base.

[0044] Collecting relevant data such as administrative region map, land use status map, high-definition orthographic image map, wine sorghum planting base map, soil type map, etc., which are mainly used for image basis for point layout auxiliary reference and field sample collection.

[0045] Step 2: Making a point layout analysis base map.

[0046] Using ArcGIS software, combined with administrative divisions (county boundaries, township boundaries, village boundaries), water system (surface water, groundwater), accumulated temperature distribution, soil type distribution, land use status, topography, traffic (highway), vegetation, geography, geology and other basic nature map. Using the spatial overlay analysis technology of the layer, the basic base map and the sorghum planting base map spot are formed into a point distribution analysis base map.

[0047] Step 3: zoning and grading of ecological environmental factors.

[0048] (1) Climate

[0049] The climate mainly considers the annual accumulated temperature. According to the distribution of different annual accumulated temperature, the annual accumulated temperature is divided into the following grades: less than 4000℃, 4000-4500℃, 4500-5000℃, 5000-5500℃, and more than 5500℃.

[0050] (2) Soil type

[0051] Taking the main soil types in Renhuai City as an example, the soil types are divided into yellow soil, limestone soil, purple soil, paddy soil, etc.

[0052] (3) Topography

[0053] The topography mainly considers the slope, which is divided into the following grades: 2° or less, 2-6°, 6-15°, 15-25°, and more than 25°.

[0054] Step 4: monitoring point layout.

[0055] Taking the orthographic image map of sorghum base (0.5 resolution) as the base map, combined with the cultivated land slope, accumulated temperature distribution map, soil type map, and other layers, according to the zoning and grading of ecological environmental factors, the soil type, climate (annual accumulated temperature), and topography (slope) are cross combined, i.e. 5 accumulated temperature grades, 4 soil types, and 5 slope grades are combined, forming 100 point representative types (Table 1). Grid method is used to assist point layout (Table 1). Figure 2 ), requiring 3 or more points for each point type, ensuring sample statistical quantity and representativeness.

[0056] Table 1: Point representative type table (taking Renhuai City as an example)

[0057]

[0058]

[0059]

[0060] Step 5: Point verification.

[0061] Combined with the existing data, the preliminary point layout scheme is verified on site to check whether the land meets the sampling requirements. Mainly verify whether the point meets the layout principle and the requirement of the work goal. According to the high-resolution remote sensing image, verify the representativeness and sampling feasibility of the point, and optimize the sampling point within the allowable range.

[0062] Step 6: Point adjustment.

[0063] After the reconnaissance, if the point cannot be reached, the field is occupied by construction land, the field is fallow, the planted crop is not sorghum, and the sorghum is seriously damaged, etc. The point needs to be adjusted. It can be adjusted to the surrounding land (the principle is not more than 50 meters) as soon as possible.

[0064] Step 7: Quality control point layout.

[0065] Refer to the "Technical Regulations for the Collection, Flow, Preparation and Preservation of Agricultural Product Samples" to determine the number of agricultural product samples and points. At the same time, add a parallel sample to the original sample. According to the principle of not more than 47 agricultural product sampling points, set up 1 coded parallel sample point.

[0066] Step 8: Encode the point.

[0067] The point code consists of 15 digits and 1 letter, mainly divided into 5 parts, for example 52038200011W2022, which represents the soil sample collected in 2022 in the cultivated land of No. 0001 sampling point in Renhuai City, Guizhou Province.

[0068] (1) The first 6 digits are the administrative region code. According to "Administrative Division Code of the People's Republic of China" (GB / T 2260-2015) and the latest administrative division code of county and above, 1-2 digits are the administrative unit code of the province, "52" for Guizhou Province, 3-4 digits are the administrative unit code of the city, "03" for Zunyi City, and 5-6 digits are the administrative unit code of the county, such as "82" for Renhuai City.

[0069] (2) The 7th-10th digits are the sampling point code. Take the county as the unit, and code from north to south and from west to east in principle. The 4 digits start from 0001 and are coded continuously, and there should be no empty or duplicate numbers (the point of agricultural product-soil collaborative collection shares a sequential code, which is convenient for subsequent result analysis).

[0070] (3) The 11th digit is the agricultural land type code. 1 for cultivated land, 2 for garden land, and 3 for pasture.

[0071] (4) The 12th digit is the sample code. The letter "S" represents the sample type as "soil".

[0072] (5) The 13th-16th digits are the sampling year. If the sampling date is 2022, the sampling year is 2022.

[0073] After the point layout is completed, the following point table is formed, and the sampling points are found according to the point information to collect samples.

[0074] Table 2 Point table

[0075]

[0076] Table 3 gives the monitoring effect of some point representatives (taking the yield of highland barley in Renhuai City as an example).

[0077] Table 3 Monitoring effect of some point representatives (taking the yield of highland barley in Renhuai City as an example)

[0078]

[0079]

[0080] As can be seen from Table 3, when the soil type is paddy soil, the annual accumulated temperature is 4000-4500℃, and the slope is 15-25°, the yield of highland barley is the lowest, which is 241.50 kg / mu; when the soil type is purple soil, the annual accumulated temperature is 4500-5000℃, and the slope is 2° or less, the yield of highland barley is the highest, which is 368.83 kg / mu. The above results show that by integrating the key ecological environmental resource characteristics such as soil type, annual accumulated temperature and slope, the point layout has certain scientificity and rationality, and has important significance in the production practice of highland barley.

[0081] In this embodiment, by integrating key ecological environmental resource characteristics such as climate, soil, topography and the like, the monitoring points are scientifically laid out, and the spatial representativeness and ecological rationality of the points are significantly improved. This layout method based on ecological environmental elements as the core basis can more comprehensively and accurately evaluate the real ecological conditions of highland barley production areas, and provide reliable scientific support for subsequent analysis and application of sampling data. At the same time, this embodiment further strengthens the internal correlation between high-quality production area ecological environment and highland barley yield, not only optimizes the layout of monitoring points in highland barley planting areas, but also lays a solid foundation for improving highland barley quality and ensuring stable raw material supply. In addition, through precise monitoring and data analysis, the action mechanism of ecological environmental factors on the formation of highland barley quality can be revealed in depth, which provides scientific basis for formulating targeted cultivation technical measures and realizing high-quality development of highland barley industry.
