风险感知、农业社会化服务与稻农生物农药技术采纳行为 总被引:2,自引:0,他引:2
在农业社会化服务体系不断完善的背景下,利用鄂、赣两省704户稻农的调查数据,采用二元Logit模型实证分析了风险感知和农业社会化服务对稻农生物农药技术采纳行为的影响.结果表明:(1)农户对生物农药技术的采用率较低,仍有55.54%的稻农未采用生物农药;(2)风险感知对稻农生物农药技术采纳行为存在显著影响,技术风险感知和市场风险感知越强的稻农,采用生物农药技术的可能性越小;(3)农业社会化服务对稻农生物农药技术采纳行为具有显著的正向作用,且能有效缓解风险感知对稻农生物农药技术采纳行为的抑制作用;(4)相较于规模户,农业社会化服务更能有效缓解市场风险感知对小农户采用生物农药技术的抑制作用,但对其技术风险感知的缓解作用则不明显.因此,在加大技术宣传和田间地头指导,完善农资市场和农产品市场体系,增加生物农药补贴力度以降低农户技术与市场风险感知的同时,有必要通过拓展农业社会化服务的服务内容和服务对象,优化小农户的农产品市场环境,以此促进生物农药技术的推广和应用. 相似文献

Diversity of antibiotic resistance genes and encoding ribosomal protection proteins gene in livestock waste polluted environment 总被引:1,自引:0,他引:1

The rapid development and increase of antibiotic resistance are global phenomena resulting from the extensive use of antibiotics in human clinics and animal feeding operations. Antibiotics can promote the occurrence of antibiotic resistance genes (ARGs), which can be transferred horizontally to humans and animals through water and the food chain. In this study, the presence and abundance of ARGs in livestock waste was monitored by quantitative PCR. A diverse set of bacteria and tetracycline resistance genes encoding ribosomal protection proteins (RPPs) from three livestock farms and a river were analyzed through denaturing gradient gel electrophoresis (DGGE). The abundance of sul(I) was 103 to 105 orders of magnitude higher than that of sul(II). Among 11 tet-ARGs, the most abundant was tet(O). The results regarding bacterial diversity indicated that the presence of antibiotics might have an evident impact on bacterial diversity at every site, particularly at the investigated swine producer. The effect of livestock waste on the bacterial diversity of soil was stronger than that of water. Furthermore, a sequencing analysis showed that tet(M) exhibited two genotypes, while the other RPPs-encoding genes exhibited at least three genotypes. This study showed that various ARGs and RPPs-encoding genes are particularly widespread among livestock. 相似文献

为研究高燃速推进剂成型过程中的安全性,根据配方组成和工艺条件,对其压伸过程的热点形成因素进行了理论分析,并采用热-结构耦合方法,选择有限元软件ABAQUS对其不同工艺条件下的压伸过程进行了建模分析。结果表明:在压伸过程中,物料在收缩段承受的压力最大,且温度变化显著。物料中残留的气泡是影响高燃速推进剂压伸成型过程安全性的主要因素。当物料中有残留气泡时,随压伸过程所加的载荷不同,气泡的最高温度会显著上升,载荷为15MPa时,气泡的最高温度可达139.3℃;载荷为20 MPa时,温度可达264.2℃。 相似文献

AbstractThe roles of PM2.5-induced mitochondrial damage and oxidative stress on mast cell degranulation were examined in vitro. Mast cells were treated with suspensions of PM2.5 in Dulbecco’s modified Eagle’s medium at concentrations from 25 to 200?mg/L in the absence or presence of 10?mmol/L N-acetyl-L-cysteine. Biological effects and mitochondrial function were assessed by determining cell viability, β-hexosaminidase release, interleukin-4 secretion, reactive oxygen species generation, adenosine triphosphate production, potential alteration of mitochondrial membrane, and activities of mitochondrial electron transport chain complexes I and III. Exposure of mast cells to PM2.5 induced reduction of adenosine triphosphate production, collapse of mitochondrial membrane potential, and inhibition of the activity of complex III. Co-treatment of mast cells exposed to PM2.5 with N-acetyl-L-cysteine attenuated cytotoxicity and the production of reactive oxygen species, and decreased the release of β-hexosaminidase and interleukin-4. Evidently, PM2.5-induced oxidative stress plays an essential role in mitochondrial toxicity and mast cell activation. 相似文献
