. Pre-emergent herbicides can have negative effects on maize seeds. The objective of this study was to model seed soaking curves through the processing of red-green-blue imagery of maize seeds under the influence of concentrations of s -metol-achlor + atrazine on both the soaking kinetics and primary root emission. Seeds were placed to soak for 114 h in Petri dishes containing aqueous solutions of a herbicide containing s -metolachlor (290 g l -1 ) + atrazine (370 g l -1 ) with the following concentrations: 0% (water only), 2, 5, 10, 20 and 50%, based on the recommended dose (4.0 l of the commercial product per hectare). The images were systematically taken from a flatbed scanner with artificial light control. The red excess index was adapted to improve image segmentation. From the binary masks applied, the soaking curves for each herbicide concentration were obtained using estimates of seed intumescence over time. The soaking curves were described by fitting Peleg’s model. The herbicide concentration has signifi cant effects on both the absorption rate and primary root emission; the absorption rate was reduced by 50%. A concentration of s -metolachlor (290 g l –1 ) + atrazine (370 g l –1 ) in aqueous solution that is above 20% can fully inhibit seed germination.
.紧急使用前的除草剂会对玉米种子产生负面影响。本研究的目的是通过处理玉米种子的红-绿-蓝图像，在s-metol achlor+阿特拉津浓度对浸泡动力学和一次根系排放的影响下，对种子浸泡曲线进行建模。将种子放入培养皿中浸泡114小时，培养皿中含有除草剂的水溶液，该除草剂含有s-甲草胺（290 g l-1）+阿特拉津（370 g l-2），浓度如下：0%（仅水）、2%、5%、10%、20%和50%，基于推荐剂量（每公顷4.0 l商业产品）。这些图像是从带有人造光控制的平板扫描仪上系统地拍摄的。采用红色过量指数来改进图像分割。从应用的二元掩模中，使用种子随时间膨胀的估计值获得了每种除草剂浓度的浸泡曲线。通过拟合Peleg模型描述了均热曲线。除草剂浓度对吸收速率和一次根排放都有显著影响；吸收率降低了50%。s-异丙草胺（290 g l–1）+阿特拉津（370 g l–2）在水溶液中的浓度高于20%可以完全抑制种子发芽。

. The aim of the study was to evaluate the effect of different mineral-organic mixtures on changes in soil microbial composition and chemical properties. The design of the pot exper iment included 6 treatments: soil without fertilization – C, soil fertilized with mineral NPK fertilizers – MF, soil with NPK + 3 or 6% lignite and 3% zeolite-vermiculite composite (MF+CW3%, MF+CW6%), soil with NPK + 3 or 6% leonardite and 3% zeolite-vermiculite composite (MF+CL3%, MF+CL6%). The test plants were spring oilseed rape and spring wheat. The highest number of microorganisms was observed: for oilseed rape – in the soil of the MF+CW3% and MF+CW6% treatments, and for wheat – in the soil of the MF+CL3% and MF+CL6% treatments. The maximum percentage increase in the number of analysed micro organisms, for spring rape and spring wheat, respectively, was: bacteria 190% (MF+CW3%) and 1198% (MF+CL3%), mould fungi 221% (MF+CW3%) and 1601% (MF+CL3%), Azotobacter spp. 248% (MF+CW6%) and 251% (MF+CL3%), actinomycet es 116% (MF+CW3%) and 251% (MF+CL3%). The beneficial effect of the applied mineral-organic mixtures on soil biological activity is closely related to the effect of these materials on soil chemical properties, such as pH or electrical conductivity, which was confirmed by the calculated correlation coefficients.

. The objective of this report was to classify ingredients based on their flowability. Twenty-six different feed ingredients (52 samples) were used including cereal grains, cereal by-products, oilseeds, oilseed meals, and animal-origin products. As an indication of flowability, the angle of repose was determined using a funnel test. In general, high protein oilseed meals had the lowest angle of repose, and therefore they had the highest flow ability with the exception of cottonseed meal. Corn gluten feed and wheat middlings had the highest angle of repose values (39 and 34°, respectively), and therefore they had the lowest flowabil ity. Ingredients with a range of angle of repose values between 22 and 25°, between 27 and 30°, and more than 30°, were categorized as having an easy flow, a moderate flow, and cohesive, respective -ly. The greater the protein content, the smaller the compressibility value ( r = –0.38) and the lower the angle of repose ( r = –0.42). An increase in the ether extract content of the ingredients resulted in a subsequent increase in angle of repose ( r = 0.31) and therefore a decrease in flowability (p<0.05). The angle of repose was positively correlated with compressibility and the Hausner ratio. In conclusion, oilseed meals were classified as “easy flow”, most by-products as “moderate flow”, and cereal grains as “cohesive”.

. The paper presents the research results of the response of “Ramos” potatoes under impact loading conditions. The parameters characterizing the impact such as: maximum stress, maximum force, impact time, maximum deformation, permanent deformation and restitution coefficient were determined. The extent of the damage was also assessed on the basis of the parameters describing the particular bruise such as: bruise depth and width. The impact parameters were related to the bruise size in order to determine the damage threshold for the potatoes under impact loading conditions and to show which parameters describe the bruise beginning to manifest itself. For the tested potato cultivar with a weight of 160-190 g the initiation of the bruise was found to occur at an impact velocity of 1 m s -1 . This corresponded to a bruise threshold (drop height) of 50 mm. The restitution coefficient changed to an insignificant extent which amounted to 0.44-0.49 in the tested range of the impact velocity which proves that the energy losses during the potato impact are constant and independent of the impact velocity. The maximum stress increased with increasing impact velocity, reaching a constant value of 0.9 MPa for the highest impact velocities. The stabilization of the maximum stress indicates that the damage to the potato tissue was determined by exceeding the specified stress value.

. Entisols are widely distributed in the hilly areas of southern China. They are affected by serious soil erosion and extensive agricultural activities, the structural and hydraulic properties of particular Entisols may differ. Characterizing soil structure and hydraulic properties is important with regard to the development of an understanding of the hydrology and ecosystem functions of shallow Entisols. X-ray computed tomography was used to characterize and quantify the soil pore structure under four typical land use types (cropland, grassland, tea orchard and forest land) from a hilly landscape in South China and the hydraulic properties of the soil including its saturated hydraulic conductivity and water retention curve were measured. The results showed that the soils under the grassland retained 14 and 21% more water at saturation than those under the cropland and tea orchard, respec-tively. The Entisol in the forest land had a significantly larger macroporosity (0.214 mm 3 mm –3 ) compared with that in the cropland (0.117 mm 3 mm –3 ) and tea orchard (0.131 mm 3 mm –3 ). The contribution of pores with a diameter >4 mm as compared to the total computed tomography derived porosity was 62.4% in the forest land, while this size class contributed 69 and 47.3% to the total porosity in the tea orchard and grassland, respectively. The saturated hydraulic conductivity value was well correlated with the degree of anisotropy and the fractal dimension.
Entisol广泛分布于中国南方丘陵地区。它们受到严重的土壤侵蚀和广泛的农业活动的影响，特定Entisol的结构和水力特性可能不同。表征土壤结构和水力特性对于理解浅层土壤的水文和生态系统功能非常重要。利用X射线计算机断层扫描技术对我国南方丘陵区四种典型土地利用类型（农田、草地、茶园和林地）下的土壤孔隙结构进行了表征和量化，并测量了土壤的水力特性，包括饱和导水率和保水曲线。结果表明，草地土壤饱和保水率分别比农田和茶园高14%和21%。与农田（0.117 mm 3 mm–3）和茶园（0.131 mm 3 mm-3）相比，林地中的Entisol具有更大的大孔隙（0.214 mm 3 mm-3）。与计算机断层扫描得出的总孔隙度相比，直径>4mm的孔隙在林地中的贡献率为62.4%，而这一尺寸类别在茶园和草地中分别占总孔隙度的69%和47.3%。饱和导水率值与各向异性程度和分形维数有很好的相关性。

. Maize ( Zea mays ) is one of the key crops in the world, taking third place after wheat and rice in terms of cultivated area. This study aimed to demonstrate the potential of non-destructive hyperspectral imaging in the wavelength range of 400-1000 nm to discriminate between and classify maize kernels in three cultivars by using non-destructive hyperspectral imaging in the wavelength range of 400-1000 nm. Three cultivars of maize kernels were exposed to hyperspectral imaging with 20 rep -lications. Predictor variables included 28 intensities of reflection wave for spectral imaging and 4 variables in terms of the weight, length, width, and thickness of a single kernel. The classification was successfully performed through Linear Discriminant Analysis and Artificial Neural Network methods, taking into account 32, 15, and 5 predictor variables. According to the results, Linear Discriminant Analysis with 32 predictor variables is characterized by a high degree of accuracy (95%). The most important predictor variables included the reflection wave intensity of the third peak, the wavelength intensity of 490 nm, the wavelength intensity of 580 nm, and the weight and thickness of a single kernel.

. Superior agricultural yields are obtained from seeds which have a high physiological potential, these are conserved in the post-harvest stage. Thus, it is crucial to implement post-harvest projects with appropriate technologies related to the equipment used and the control of operations. This article presents a review of the technical-kinetic developments in the area of the technology of processing post-harvest soybean seeds, with a particular focus on the evolution and current circumstances of the sector. The findings from this research reveal significant tech nological advances in the drying, processing and storage of seeds at different levels and in various areas of soybean production. In drying systems, temperatures of up to 40°C are recommended, while seed batches must remain static in drying chambers. When processing and standardizing seeds, it is recommended that low-moving equipment and abrupt contacts with mechanical systems, such as pneumatic and gravity separators, be employed to minimize dropping and contact with seeds. In soybean storage, the applications of technologies that can control temperature and relative humidity, and also maintain the storage moisture content in a hygroscopic balance are recommended. The storage of seeds in coated big bags and artificial cooling; a controlled and modified atmosphere serve to preserve essential seed qualities. This review concludes that over the years, there has been a reduction in the cumulative losses due to post-harvest processes.
