In this study, the compound 1-(4-(tert-butyl) phenyl)-3-hydroxy-2-methylpyridine-4 (1H) - one (hereinafter referred to as HAINU-19) was used as the active ingredient to prepare the microemulsion and determine its antifungal activity. First, through the screening solvents, co-solvents, and transparent, the formulation of 2.5% HAINU-19 microemulsion (mass fraction) was determined as follows: 2.5% HAINU-19, 15% ethanol, 10% cyclohexanone, 20% transparent (1601# : 500# : AC1810 = 3 : 3 : 1), with distilled water making up to 100%. All indicators meet national standards. The bioassay result of pot experiments showed that the protective and curative effects of 2.5% HAINU-19 microemulsion on wheat stripe rust were 100% at 1000, 500, and 250-fold dilutions, and curative effects were 76.67%, 81.00%, and 82.33%, respectively. The field trial results showed that the 2.5% HAINU19 microemulsion had a control efficacy of 86.13% on rice sheath blight at a 100-fold dilution and 71.24% at a 200-fold dilution. This study can provide an experimental basis and technical support for the development and application of the antifungal compound HAINU-19. [ABSTRACT FROM AUTHOR]

Analysis of flotation samples from late Shang Dynasty to Han Dynasty excavated in 2023 in the east of the Nandongtao Site in Wuzhi, Henan Province shows that millet, broomcorn millet and soybean were the food crops of the ancestors in late Shang period. The crop combination reflected the dominant role of millet in the agricultural production of the ancestors, and had certain similarities with other plant archaeological records in the Central Plains in late Shang period. In the archaeological records from the eastern Zhou Dynasty to Han Dynasty, millet agriculture, represented by millet and broomcorn millet, was still the composition of the ancestors’ livelihood. The flotation results of Nandongtao site provide evidence for the exploration and research of agricultural structure from Shang Dynasty to Han Dynasty in northwest Henan. With further excavation and research, the understanding of agricultural economy and subsistence system of ancestors in different periods in this area will be deepened. [ABSTRACT FROM AUTHOR]

Current point cloud semantic segmentation methods based on deep learning tend to overlook the boundary of objects in transition area, resulting in the problem of ambiguous features at the boundary. This article proposed a point cloud semantic segmentation method with boundary-aware and multi-feature fusion (BA-MFF). Firstly, the backbone network was optimized to make the extracted features more robust. Secondly, boundary-aware module(BAM)was designed to focus on the boundaries of objects in transition area. This module consisted of a boundary point prediction module(BPPM)and a feature aggregation module (FAM). The boundary point prediction module predicted the points belonging to boundaries by learning the features of neighboring points, and the feature aggregation module performed discriminative aggregation of point cloud features within the neighborhood. Finally, for more discriminative features, a multi-feature fusion module(MFFM)was introduced, which fused features between different channels. The experimental results show that the mean Intersection over Union (mIoU) of this method reaches 63.7% on the ScanNetV2 dataset. The Overall Accuracy (OA) and mIoU on the S3DIS are 88.2% and 62.3%, respectively. The method in this paper effectively focuses on the transition area and has some segmentation superiority.

In order to obtain strains with good antagonistic effect against pathogen of red kidney bean root rot, in this study, endophytic bacteria were isolated from Xanthium sibiricum by tissue separation method. The antagonistic bacteria were screened and identified by plate confrontation method using Fusarium oxysporum as the target, morphological characteristics observation, and molecular biology method. The inhibitory effect of the antagonistic bacteria on Fusarium oxysporum was studied by coculture method. Finally, the inhibition spectrum of the antagonistic bacteria and its effect on germination of red kidney bean seeds were also studied. The results showed that 36 strains of endophytic bacteria were isolated from root, stem and leaf of Xanthium sibiricum. The strain xj-1-2 with obvious inhibitory effect on Fusarium oxysporum was screened from the strains. Combined with morphological and gyrB gene sequence analysis, the strain xj-1-2 was identified as Bacillus velezensis. The strain xj-1-2 could cause more hyphal branches and less sporulation of Fusarium oxysporum. The inhibition rates of spore germination at 4 h, 6 h, and 8 h were 100%, 79.45% and 73.54%, respectively. The strain xj-1-2 had broad-spectrum antifungal activity against 8 kinds of pathogenic fungi such as Fusarium chlamydosporium, Fusarium redolens, and Fusarium tricinctum. After treating red kidney bean seeds with 1×107, 1×108, and 1×109 cfu/mL xj-1-2 bacterial suspension and fermentation solution, there was no significant difference in germination rate and bud length compared with control, which proved that xj-1-2 was safe for the growth of red kidney bean. In conclusion, Bacillus velezensis xj-1-2 strain with broad-spectrum antifungal activity isolated and screened from Xanthium sibiricum provided strain resources for biological control of red kidney bean root rot.

Sand waves widely exist in natural river channels and they play an important role in the change of river bed morphology. In this paper, by using a plexiglass rod in a glass water tank to simulate the effects of rigid emergent plants on various movement patterns of sand waves, and introducing the MIKE21 hydrodynamic numerical model, we observed the sand waves in the glass water tank from both macro and micro perspectives. Wavelength, wave width, wave height, wave length-to-width ratio, and front-to-back stream wavelength ratio were affected by plants in water. The mechanism of group movement of river sediment was explored, which provided some reference for natural river sediment management. The test results show that under the influence of the emerging plants to the changes of the flow regime, the wavelength, wave width and wave height of the sand waves change significantly. Especially under the influence of the plant flow, the speed of the sediment particles on the sides of the plants increases, showing a scouring situation, the movement pattern of sand waves also follows a complex movement pattern and there are significant differences in the shape of sand waves upstream and behind tree planting.
