小农户在现代农业发展中的困境与出路——基于福建省漳州市的观察

在乡村振兴与农业现代化发展大背景下,小农户经营面临前所未有的挑战。对福建省漳州地区小农户发展现状的观察发现,受主客观条件制约,小农户在现代农业发展中面临缺乏面向大市场的议价决策能力,现代科技运用滞后,与大资本间利益连接机制不稳定,农业社会化服务体系不健全等一系列困境。因此,要通过提高小农户组织化程度,拓宽市场渠道,提升小农户发展现代农业的能力,完善农业社会化服务体系,拓宽农业功能等助力小农户融入中国农业现代化进程。     

高寒草地畜牧业产业化的障碍与实现路径——以甘南州合作市为例

草地畜牧业是合作市的主导产业,受自然条件和社会经济发育程度的深刻影响,农牧业经济要素互补性差;畜牧业内部同构性较强,区域分工不明显;畜产品的商品化过程粗放、低质、低效;畜产品加工企业门类不全,规模不大,带动性差;普遍缺少各种形式的中介机构和协会,农牧民自组织能力不足;缺少交易市场,要素流动受阻,致使畜牧业产业化进程缓慢。因此,在保护草原生态环境的前提下,加强基地建设,大力发展龙头企业,强化农牧业服务体系,实现草地畜牧业向现代畜牧业转型。     

Plant transposable elements,with an emphasis on grass species

Transposable elements are presents in all known genomes so far, and have the faculty of changing their genomic location and/or number of copies within the genome. They are mobile endogenous genetic elements, with a large variety of structure and transposition mechanism. In crops, they compose the major part of the nucleic DNA, up to 80% in some cereals like maize and wheat. Despite their omnipresence, they are largely unknown and uncharacterized within the Poaceae family. In this review, we describe a possible classification of the elements present in this family, some of their known transposition mechanism, their known activity and possible action in crops, and their possible origin.

Evaluation on Tolerance of Montmorillonite as a Mycotoxin Adsorbent

In order to study the tolerance dose of Kunming mice to montmorillonite as a mycotoxin adsorbent in diets,the experiment selected 60 healthy male Kunming mice with initial average body weight of (17±0.12)g,randomly divided them into 5 treatments with two replicates per group and 6 mice per replicate.Five experimental diets were added to 0 (control group),0.5%,1%,2% and 5% montmorillonite,respectively.After 30 days,the growth performance,nutrients apparent digestibility,serum biochemical indices and internal organization were tested to determine the tolerance dose of montmorillonite for Kunming mice.The results showed that the ADFI was significantly increased in 0.5% group (P< 0.05),while there were no significant differences in ADFI and ADG between 1% group and control group (P> 0.05),then the ADFI was significantly decreased with the increasing of montmorillonite supplemental level (P< 0.05).The ADG in 2% group had no significant difference when compared with the control group (P> 0.05),while significantly lower than that in 0.5% and 1% groups (P< 0.05).The apparent digestibility of DM,CP and EE showed no significant effect at any level of montmorillonite (P> 0.05).Serum ALT,AST activities and MDA content were gradually increased with the montmorillonite supplemental level increasing,and that in 1%,2% and 5% groups were significantly higher than that in control group (P< 0.05),but there were no significant differences between 0.5% group and control group (P> 0.05).Tissue sections showed that mice livers were damaged in varying degrees when the montmorillonite supplemental level was 5%.In conclusion,based on a comprehensive consideration of all indexes,it could be seen that the tolerance dose of the tested montmorillonite for Kunming mice was between 0.5% and 2% when mycotoxin contents in diets were in security range.

The potential of informal institutions for marine fisheries management—A case study of a coastal commune in Vietnam

The potential of informal institutions for sustainable management of marine fisheries was examined. The study is based on both primary data collected through two group discussions and interviews and secondary information, including material related to fishing gear operation and whale worship. It shows that informal institutions, including fisher groups, fishing community norms, fisher's knowledge and whale worship have potential to strengthen institutional, ecological, social and community aspects of sustainable fisheries development. Although these informal institutions are not able to fix completely all the problems faced by formal institutions, they are able to complement and consolidate formal institutions to manage marine fisheries effectively. The findings of this study suggest it is imperative that formal institutions should be improved simultaneously with informal institutions to enhance current management for sustainable marine fisheries development.
