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 driving motor temperature calculation method based on a temperature-fluid weak coupling technology. The problem of motor heat network calculation oscillation caused by transient rapid heat exchange between fluid and a motor winding and an iron core component is solved. According to the method, heat network capacitance matrix characteristics are deeply analyzed, the influence of the ratio of the maximum value and the minimum value of matrix elements on iterative calculation convergence is considered, and a certain short time period is considered, the motor cooling fluid is driven, the temperature change of the motor is small, and the internal heat transfer phenomenon is stable; according to the method, a weak coupling calculation method of a rapid change fluid field and a slow change motor internal temperature field is established, different calculation frequencies are adopted in the fluid field and the temperature field, the inherent defect that the ratio of the maximum value to the minimum value of a heat capacity matrix element is too large is overcome, and rapid and stable calculation of the temperature of the driving motor is achieved. The temperature calculation method is clear in thought and easy to operate, has the advantages of being easy to implement, rapid in calculation, universal and the like, and shows excellent performance.

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.

The invention discloses a laser weeding device capable of accurately identifying weeds, belongs to the field of farmland maintenance, solves the problem that an existing laser weeding robot is prone to cutting deviation due to the fact that the distance between the weeds and seedlings is too small, and comprises a weeding machine host, a scanning camera and a cutting assembly. A scanning camera is rotatably installed on the side face of the weeding machine host, and a cutting assembly is fixedly installed at the bottom end of the side face of the weeding machine host. By arranging the blowing mechanism and the cutting assembly, weeds and crop seedlings in the field can be rapidly and stably analyzed and scanned, and then the weeds are cut; when the distance between weeds and crop seedlings is too small, the weeds and the seedlings can be blown at the same time, the top ends of the weeds and the top ends of the seedlings incline towards the other side, and at the moment, the laser cutting assembly can stably cut the roots of the weeds, so that the stability of equipment during operation is enhanced, and treatment operation can be conducted according to the weeds under different conditions.

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.
