This utility model provides a multi-level control-based bean spraying device, specifically belonging to the field of bean cultivation technology. Through the meshing connection of a first bevel gear and a second bevel gear, a control motor can drive a rotating rod to rotate. Through the meshing connection of a push rod and the control gears, the push rod can drive the rotating rod to rotate. The two different control methods allow the device to be used in different situations, improving its ease of use. The adjustable platform allows for simultaneous height adjustment of the two spray heads, enabling the device to spray bean plants growing at the same stage. This utility model includes a pesticide storage tank and an adjustable platform, as well as spray heads, spray nozzles, and a control component. The pesticide storage tank has a storage cavity inside, spray heads are located on both sides of the tank, an adjustable platform is located above the tank, spray heads are located on both sides of the top surface of the platform, and a control component is located in the center of the top surface of the platform.

This invention discloses a method and its application for creating stress-resistant mutants of common bean using chemical mutagenesis. The main steps include: determining the screening concentration of hydroxyproline (Hyp), determining the median lethal dose of ethyl methanesulfonate (EMS), and subculturing the stress-resistant mutants. After 3-5 subcultures, the stress-resistant mutants screened by this invention ultimately yielded 31 cotyledonary nodes of common bean resistant to hydroxyproline (Hyp), with a mutation rate of 8.16%. This invention can induce mutagenesis and directionally screen for stress-resistant common bean mutants, providing material support for stress-resistant breeding of common bean.

This invention discloses a non-destructive method for detecting protein content in common bean seeds based on hyperspectral imaging, relating to the field of non-destructive testing of agricultural products. It addresses the problems of traditional detection methods being highly destructive, cumbersome, and inefficient, as well as the redundancy, inaccurate feature extraction, and poor model adaptability of existing hyperspectral detection technologies. The invention includes: screening standardized common bean seeds; acquiring hyperspectral data; extracting the average spectrum of the samples using image preprocessing and spectral extraction techniques; eliminating redundant bands using EDA analysis; extracting relevant features using any one of the SFE, PLS-VIP+Pearson+p-value, or KNN-MI schemes; and constructing and selecting the optimal prediction model. This invention can be applied to the screening of high-protein single plants in common bean breeding, automated grading of common bean seed quality, or, after parameter adjustment, to the non-destructive detection of protein content in seeds of other edible legume crops such as peas, chickpeas, and cowpeas, and the tested seeds can be sown normally.

The application relates to a primer group for detecting a bean golden yellow mosaic virus in Amorphophallus konjac, a kit and a method and application thereof, and belongs to the technical field of biology. The primer group comprises a primer pair TYLCCNV, a primer pair SyLCV and a primer pair TbLCYnV; the bean golden yellow mosaic virus is a golden yellow mosaic virus, a Yunnan tobacco leaf curl virus and a Chinese tomato yellow leaf curl virus. The primer group has the characteristics of high specificity and high sensitivity, and can quickly and efficiently detect the three viruses of TYLCCNV, SyLCV and TbLCYnV from the Amorphophallus konjac.
