Journal of Agricultural Chemistry and Environment 2024年第3期13卷 282-299页

作者： Henriette Doukahonon Guigui Bi zaï Pacôme zaouli Alain Serge Coulibaly Juliette Ky Dedi Training and Research Unit of Sciences of Nature Laboratory of Biology and Improvement of Plant Production Nangui Abrogoua University Abidjan Cte dIvoire Department of Plant Biology Training and Research Unit (UFR) of Biological Sciences Peleforo Gon Coulibaly University Korhogo Cte dIvoire

Onions are a horticultural crop of great economic, dietary and medicinal importance, and are highly prized by the ivorian popula.ion. However, production remains low, due to a number of constraints, including para.itic attacks. The most frequent is fusa.iosis caused by Fusa.ium sp., a pathogen that causes enormous damage to onion crops. Faced with these attacks, chemical control appears to be ineffective, with consequences for human health and the environment. This is why the search for effective alterna.ive methods that respect the environment and human health is so necessary. it is in this context that this study was carried out, with the general aim of controlling fusa.ium wilt in onion crops, with a view to improving onion production in ivory Coast through the use of effective microorga.isms. The experimental set-up used for this purpose was a fisher block with complete randomiza.ion, comprising three replicates. A fungal spore concentra.ion of 106 spore/mL of Fusa.ium sp., three doses (1%;2.5% and 5% v/v) of EM and one dose of a chemical fungicide (30 mL/16L) were tested on young onion plants. Each block consisted of nine sub-plots with nine treatments. Health parameters (incidence and severity) and agronomic parameters (growth and yield) were assessed. Microbiological analysis of the EM revealed the presence of nine morphotypes of Trichoderma sp., Aspergillus clavatus, Aspergillus flavus, Aspergillus sp., Penicillium sp., Rhizopus sp., lactic a.id bacteria of the Ba.illus fa.ily and the yeast Saccharomyces cerevisiae. Field experimenta.ion showed that the 5% EM microbial solution reduced the incidence and severity of fusa.iosis compared with the chemical fungicide, and proved to be the best. This dose reduced yield losses by 7.14%, while improving onion growth and yield by over 5%. The results demonstrated the a.ility of the EM solution to effectively control the causal agent of basal rot in onion crops.

Terbium-picrate triethylene glycol（EO3-Tb-Pic） complex was prepared in thin film and single layer device structure of iTO/EO3-Tb-Pic/Al, using spin coa.ing technique. The UV-Vis absorption spectroscopy analysis was performed to evaluate the electronic molecular transition of the complex. The optical band gap, Eg estimated from the Tauc model revealed that EO3-Tb-Pic thin film exhibited a direct transition with Eg of 2.70 eV. The electronic parameters of the iTO/EO3-Tb-Pic/Al device such as the idea.ity factor n, barrier height Φb, satura.ion current io, and series resistance Rs, were extracted from the conventional lni-V, Cheung＇s functions and Norde＇s method. it was found that the evaluated parameters calculated from Norde＇s and Cheung＇s methods were consistent with those calculated from the conventional i-V method. in the double loga.ithmic i-V plot, three distinct regions based on the slope were identified, and the conduction mecha.isms were discussed and explained. The mobility, μ value was estimated from SCLC region as 2.58×10^–7 cm2/（V·s）. This newly obtained lantha.ide complex may be potentially utilized in electronic devices.

针对现有检测开沟质量效率低、精度差等问题,设计了一套由激光雷达、编码器、便携式计算机和支架等构成的非接触式果园开沟宽度深度监测平台,基于编码器获取测量平台前行方向位移,并与上位机软件形成整套采集系统,可快速获取果园沟型三维坐标。为了降低外部环境对点云数据处理的影响,采用直通滤波进行果园沟型的有效区域选取,借助MatLab获取其三维点云模型,实现对果园开沟沟形的重构与沟深、沟宽数据的监测。通过重构沟型参数与实测参数对比分析可知:两者宽度相关系数为0.83,均方根误差为0.008,相对误差为2.47%;深度相关系数为0.75,均方根误差为0.009,相对误差为2.76%。研究结果表明:重构沟型参数与实际沟型参数吻合度较高,可精确反映原有沟型形貌特征,为智慧农业果园开沟质量智能检测的构建提供了参考。
