This invention provides KASP primer pairs, kits, methods, and applications for detecting SNP combinations related to soybean protein content. The SNP combinations related to soybean protein content include SNP1 at position 4903434 on chromosome Chr11, SNP2 at position 47558915 on chromosome Chr10, and SNP3 at position 47559046. This invention also provides three sets of KASP primer pairs for detecting SNP1, SNP2, and SNP3, used to detect soybean genetic DNA and genotype the three SNP loci to determine whether the species has high protein content. The detection method provided by this invention is fast, low-cost, and suitable for large-scale sample testing. This detection method can be applied to soybean molecular marker-assisted breeding selection, variety improvement, and germplasm resource evaluation.

The invention discloses a reflection infrared spectrum quantitative method for trace acetate in polylactic acid fiber. The method comprises the following steps: preparing a polylactic acid film standard substance; testing the infrared spectrum of the standard substance by using an attenuated total reflection mode; the method comprises the following steps: selecting an acetate characteristic absorption peak at 1571 cm <-1 > and a polylactic acid characteristic absorption peak at 1753 cm <-1 > from an infrared spectrum of a standard substance, calculating a peak intensity ratio of the two characteristic peaks as infrared characteristic intensity, and deducing a quantitative functional expression; testing the infrared spectrum of the polylactic acid film sample by using an attenuated total reflection mode to obtain infrared characteristic intensity; and substituting the infrared characteristic intensity into a quantitative functional expression, and calculating to obtain the acetate content. According to the reflection infrared spectrum quantitative method, the limitation that the traditional infrared technology is weak in response to trace components and is easily interfered by a matrix is effectively overcome, the detection accuracy and repeatability are remarkably improved, and a reliable analysis means is provided for quality monitoring of a material surface modification process.

This invention discloses a big data platform for realizing the value of agricultural tourism ecological products at the district / county level. It adopts an MVVM architecture, with the backend developed based on .NET and the frontend using Vue, HTML5, CSS3, and integrated Echarts. The database uses PostgreSQL with PostGIS, relying on ArcGIS Server for GIS services and implementing map integration through the ArcGIS API for JavaScript. The platform incorporates core accounting models for GEP (Gross Ecological Product) total value, water conservation, and ecological vouchers, including agricultural tourism ecological product surveys, ecological product value calculation, automatic value calculation, ecological voucher agricultural tourism value conversion, database updates, and user management. The platform enables visualization of various agricultural tourism ecological data charts, display of resource survey map data, and GIS spatial statistics of value and functional quantities. It supports multi-scope calculations for administrative regions, scenic areas, and custom areas, and can perform comparisons of two phases of land use data and visualized calculations of ecological vouchers. It also features ecological data year management, editing and updating, and user hierarchical permission control functions. This platform improves the standardization and intelligence of agricultural tourism ecological value management at the district / county level.

The invention relates to a high-performance log collection and analysis device, and belongs to the field of data processing. The device comprises a log collection module, a log analysis module, a data storage module, a communication interaction module, a power management module and a system monitoring module, and all the modules work cooperatively through a high-speed bus. The device disclosed by the invention can realize high-performance log collection and analysis of efficient collection, real-time analysis, safe storage and stable wired transmission of multi-scene logs, can be widely applied to scenes which have strict limitation on wireless communication and have requirements on hardware localization compatibility, and provides hardware-level support for stable operation and risk early warning of various systems.
