This framework comprises a Parallel Feature Extraction Stem, cross-attention mechanism, Dense Connection Blocks, and Inception Blocks to learn disease features at various spatial scales. The PFES extracts fine and broad disease patterns using parallel convolutional branches, while the cross-attention mechanism refines the extracted features by emphasizing disease-related information.

single-element toxicity: chromium-salinity interactions, food-chain transfer and mitigation in sugarcane agroecosystems","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1942892","Chromium contamination in sugarcane soils is often combined with co-metals and salinity caused by tannery effluent, electroplating effluent, paper mill wastewater, vinasse fertigation and filter cake. Hence, single element toxicity assessment does not provide realistic assessment of its exposure. The present review summarizes research on chromium behaviour along the soil, root, stalk and cane juice in sugarcane. Cr mobility depends on soil pH and redox potential (Eh), while salinity adds an additional control through ionic strength and chloride complexation. Sequential extraction and speciation analysis prove that bioavailable fraction is more important for plant toxicity than total Cr concentration. Cr(VI) enters roots via sulphate and phosphate transporters via mimicking oxyanions and this mechanism differs from that of other metal ions that use ion channels, a route that salt-induced PHT1 expression could plausibly modulate, although this has not been tested in sugarcane. In proxy species, combined Cr and salinity exposure raises reactive oxygen species production and membrane damage beyond the level induced by either stress alone, whereas in sugarcane the downregulation of PEP carboxylase, pyruvate orthophosphate dikinase and photosystem proteins has so far been documented only under salinity applied by itself. Whether the two stresses interact on C4 carbon assimilation in cane remains untested. Root-to-stalk transfer of Cr is low at most sites examined, but not at all of them, and measurable Cr reaches cane juice at concentrations that have driven hazard quotients above unity in two of the four field studies assessed. Bagasse biochar, biochar with nZVI, halotolerant Cr-reducing microorganisms and water management based on redox reactions all reduce Cr bioavailability, but field experiments in cane are lacking. Factorial experiments investigating Cr behaviour depending on salinity gradient, juice level speciation and field trials in ratoons are required.","甘蔗土壤中的铬污染通常与制革废水、电镀废水、造纸厂废水、酒糟灌溉和滤泥带入的伴生金属及盐分复合存在。因此，单一元素毒性评估无法对其暴露状况作出符合实际的评价。本文综述了铬在甘蔗土壤、根系、茎秆及蔗汁中行为的研究进展。铬的迁移性取决于土壤pH和氧化还原电位（Eh），而盐分通过离子强度和氯络合作用对其施加额外调控。连续提取和形态分析表明，生物有效态组分对植物毒性的意义大于总铬浓度。Cr(VI)通过模拟含氧阴离子经硫酸盐和磷酸盐转运蛋白进入根系，这一机制不同于其他利用离子通道的金属离子，而盐诱导的PHT1表达可能调控该途径，但尚未在甘蔗中验证。在替代物种中，铬与盐分复合暴露引起的活性氧产生和膜损伤超过单一胁迫诱导的水平，而在甘蔗中，磷酸烯醇式丙酮酸羧化酶、丙酮酸磷酸双激酶和光系统蛋白的下调目前仅在单独盐胁迫下得到证实。两种胁迫是否在甘蔗C4碳同化过程中发生交互作用仍未经检验。在多数已考察的位点，铬从根系向茎秆的转移量较低，但并非所有位点均如此；在所评估的四项田间研究中，有两项显示可检测到的铬到达蔗汁，其浓度已使危害商数超过1。蔗渣生物炭、负载纳米零价铁（nZVI）的生物炭、耐盐铬还原微生物以及基于氧化还原反应的水分管理均可降低铬的生物有效性，但甘蔗田间试验尚属缺乏。有必要开展考察铬行为随盐度梯度变化的析因实验、蔗汁水平上的形态分析以及宿根蔗田间试验。","Frontiers in Sustainable Food Systems","2026-10-12T00:00:00Z",74,{"impact":43,"substance":16,"depth":110,"authority":111,"freshness":149,"relevant":20,"comment":259},"综述系统梳理铬-盐交互、食物链迁移与阻控手段，指出甘蔗田间试验空白，对污染蔗区安全利用有参考价值，但属机理综述、非产业级突破。",[261],{"name":255,"url":252},[25,263,264,265,266],"食品安全","盐渍化","土壤重金属","生物炭修复",{"code":30,"slug":31,"name":32,"path":33,"parent_code":34},[269],{"code":270,"slug":271,"name":272,"path":273,"parent_code":274},"H2","soil","土壤健康与改良","\u002Ftopic\u002Fenvironment\u002Fsoil","H",{"status":37,"locked":13,"version":38,"method":39,"evidence":276},{"candidates":277,"agricultural_evidence":44},[278,282,287,293,299],{"code":30,"score":18,"supported":44,"title":279,"abstract":280,"tags":281},[165],[25,165],[25],{"code":270,"score":73,"supported":44,"title":283,"abstract":284,"tags":286},[],[285,271],"土壤",[265,264],{"code":288,"score":50,"supported":44,"title":289,"abstract":290,"tags":292},"F3",[],[291],"fertigation",[],{"code":294,"score":50,"supported":44,"title":295,"abstract":296,"tags":298},"H3",[],[297],"灌溉",[],{"code":300,"score":20,"supported":13,"title":301,"abstract":302,"tags":303},"E4",[],[],[263],[305,306],"甘蔗 铬污染 盐渍化","甘蔗汁 风险","甘蔗铬污染盐渍化-4797","10.3389\u002Ffsufs.2026.1942892",{"doi":308,"openalex_id":310,"authors":311,"venue":255,"cited_by_count":193,"oa_url":252,"card":333,"direction":337,"ingested_from":201},"W7221577366",[312,315,317,319,321,323,325,327,329,331],{"name":313,"orcid":314},"Gowtham Sornam","https:\u002F\u002Forcid.org\u002F0009-0009-1150-1568",{"name":316,"orcid":8},"Sugumaran Melkumaramangalam Palani",{"name":318,"orcid":8},"Parameswari Ettiyagounder",{"name":320,"orcid":8},"Kalaiselvi Thangavel",{"name":322,"orcid":8},"Saravanan Naaganoor Ananthan",{"name":324,"orcid":8},"Elayarajan Maharajan",{"name":326,"orcid":8},"Selva Kumar Manikkam",{"name":328,"orcid":8},"Sassikumar Datchinamoorthy",{"name":330,"orcid":8},"Sinduja Murugaiyan",{"name":332,"orcid":8},"Priyatharsini Sengottaiyan",{"tldr":334,"method":335,"finding":336,"direction":337,"opportunity":338},"综述甘蔗农业生态系统中铬与盐分交互作用、食物链传递及缓解措施，指出单元素毒性评估不足。","综述土壤-根-茎-汁中铬形态、转运与缓解技术，结合顺序提取与形态分析。","铬与盐分交互对C4碳同化影响未测，蔗汁铬危害商在部分田间研究中超1，缓解技术缺乏田间验证。","农业绿色发展与碳","可开展盐度梯度下铬形态与C4光合交互的因子实验，并验证生物炭等缓解措施的田间效果。","2026-10-13T23:30:07.200287Z",{"id":341,"title":342,"url":343,"summary":344,"summary_zh":345,"content":8,"source_name":346,"source_url":343,"published_at":347,"category":145,"cover_url":8,"hotness":12,"is_selected":13,"score":348,"score_detail":349,"sources":352,"tags":354,"primary_topic":360,"secondary_topics":361,"classification":362,"search_phrases":402,"slug":405,"view_count":193,"doi":406,"paper":407,"created_at":436},4210,"Nutrient cycling, environmental outcomes and mitigation pathways in sugarcane agroecosystems: A comparative synthesis of Brazil and Australia","https:\u002F\u002Fdoi.org\u002F10.1016\u002Fj.agee.2026.110780","Sugarcane is a major tropical crop with strong potential to support climate-smart agriculture through efficient nutrient cycling, improved nitrogen use efficiency, biofuel production and enhanced soil carbon dynamics. However, environmental outcomes vary substantially across production systems. This review compares two leading high-efficiency sugarcane systems, Brazil and Australia, examining nutrient cycling, greenhouse gas emissions, nutrient losses and soil organic carbon storage. In Brazil, large-scale rainfed operations (commonly exceeding 10,000 ha) promote high organic inputs through residue retention and recycling of vinasse and filter cake, enhancing soil carbon stocks and internal nutrient recycling; however, these practices can elevate nitrogen losses and greenhouse gas emissions when poorly synchronised with crop demand. In Australia, smaller family-owned systems (~95 ha) operate under environmental regulations and the Six Easy Steps framework, where soil-test–based management, subsurface fertiliser placement and enhanced-efficiency fertilisers target nutrient transport to Great Barrier Reef catchments. Fertiliser-N use in Australian sugarcane has progressively declined to among the lowest rates globally for the crop; however, nitrogen use efficiency remains relatively low compared with Brazil, and off-site nutrient losses have not been fully resolved at scale. Soil compaction is a critical constraint in both countries, addressed by complementary strategies: satellite-guided controlled traffic farming in Australia and strategic subsoil tillage with GPS-guided traffic in Brazil. Across both systems, residue retention, legume rotations and reduced tillage improve nutrient cycling and soil carbon accumulation. Integrating Brazil's nutrient-recycling scale with Australia's precision management offers a convergent pathway to enhance nitrogen use efficiency, reduce environmental footprints and improve sugarcane agroecosystem sustainability.","甘蔗是一种重要的热带作物，通过高效的养分循环、提高氮利用效率、生物燃料生产以及增强土壤碳动态，具有支持气候智慧型农业的巨大潜力。然而，不同生产体系的环境效益差异显著。本文综述比较了巴西和澳大利亚两个领先的高效甘蔗生产体系，考察了养分循环、温室气体排放、养分损失和土壤有机碳储量。在巴西，大规模雨养作业（通常超过10,000公顷）通过保留残茬以及回收利用酒糟（vinasse）和滤泥（filter cake）促进高有机投入，提升了土壤碳储量和内部养分循环；然而，当这些做法与作物需求同步不佳时，可能导致氮损失和温室气体排放增加。在澳大利亚，较小的家庭经营体系（约95公顷）在环境法规和“六步简易法”（Six Easy Steps）框架下运行，以土壤测试为基础的管理、肥料深施和增效肥料（enhanced-efficiency fertilisers）针对大堡礁集水区的养分迁移进行调控。澳大利亚甘蔗的肥料氮使用量已逐步下降至全球该作物最低水平之列；然而，与巴西相比，氮利用效率仍然相对较低，且异地养分损失尚未在大规模上得到完全解决。土壤压实是两国共同面临的关键限制因素，通过互补策略加以应对：澳大利亚采用卫星导航控制交通耕作（controlled traffic farming），巴西采用GPS导航交通下的战略性心土耕作（subsoil tillage）。在两个体系中，残茬保留、豆科轮作和减少耕作均改善了养分循环和土壤碳积累。将巴西的养分回收规模与澳大利亚的精准管理相结合，为提升氮利用效率、减少环境足迹和提高甘蔗农业生态系统可持续性提供了一条趋同路径。","Agriculture Ecosystems & Environment","2026-10-04T00:00:00Z",80,{"impact":110,"substance":16,"depth":110,"authority":350,"freshness":73,"relevant":20,"comment":351},14,"核心期刊发表的巴西与澳大利亚甘蔗系统对比综述，数据与结论扎实，对养分管理与减排路径有参考价值，但属学术综述、非政策或产业事件，时效性一般。",[353],{"name":346,"url":343},[25,355,356,357,358,359],"巴西","土壤固碳","养分循环","氮肥利用率","澳大利亚",{"code":30,"slug":31,"name":32,"path":33,"parent_code":34},[],{"status":37,"locked":13,"version":38,"method":39,"evidence":363},{"candidates":364,"agricultural_evidence":44},[365,369,374,381,387,392,398],{"code":30,"score":18,"supported":44,"title":366,"abstract":367,"tags":368},[165],[25,165],[25],{"code":270,"score":370,"supported":44,"title":371,"abstract":372,"tags":373},7,[],[285,271],[356],{"code":375,"score":62,"supported":44,"title":376,"abstract":377,"tags":380},"B7",[],[378,379],"温室","greenhouse",[],{"code":382,"score":50,"supported":44,"title":383,"abstract":384,"tags":386},"A7",[],[385],"轮作",[],{"code":288,"score":50,"supported":44,"title":388,"abstract":389,"tags":391},[],[390],"肥料",[],{"code":393,"score":50,"supported":44,"title":394,"abstract":395,"tags":397},"H6",[],[396],"农业生态",[],{"code":169,"score":50,"supported":44,"title":399,"abstract":400,"tags":401},[],[171],[],[403,404],"巴西 澳大利亚 甘蔗 养分循环","甘蔗 氮肥利用率 土壤固碳","巴西澳大利亚甘蔗养分循环-4210","10.1016\u002Fj.agee.2026.110780",{"doi":406,"openalex_id":408,"authors":409,"venue":346,"cited_by_count":193,"oa_url":343,"card":431,"direction":200,"ingested_from":201},"W7218417513",[410,413,416,419,422,425,428],{"name":411,"orcid":412},"Juan Ricardo Rocha","https:\u002F\u002Forcid.org\u002F0000-0003-0590-655X",{"name":414,"orcid":415},"Nicole Robinson","https:\u002F\u002Forcid.org\u002F0000-0001-6285-6179",{"name":417,"orcid":418},"Dalila Lopes da Silva","https:\u002F\u002Forcid.org\u002F0000-0003-4972-5945",{"name":420,"orcid":421},"Kristopher Woodrow-Smith","https:\u002F\u002Forcid.org\u002F0009-0008-4475-7108",{"name":423,"orcid":424},"Prakash Lakshmanan","https:\u002F\u002Forcid.org\u002F0000-0003-1725-0391",{"name":426,"orcid":427},"Cassio Hamilton Abreu–Junior","https:\u002F\u002Forcid.org\u002F0000-0002-5955-4652",{"name":429,"orcid":430},"Susanne Schmidt","https:\u002F\u002Forcid.org\u002F0000-0001-8369-1238",{"tldr":432,"method":433,"finding":434,"direction":337,"opportunity":435},"综述比较巴西与澳大利亚甘蔗农业生态系统的养分循环、环境效应及减排路径。","文献综述，对比两国甘蔗系统的养分管理、温室气体与土壤碳数据。","巴西靠规模回收、澳大利亚靠精准管理，整合二者可提升氮效率并减排。","可量化整合巴西养分回收与澳大利亚精准管理对氮效率及碳汇的协同效应。","2026-10-05T23:30:08.942071Z"]
