作为农业现代化建设和践行乡村振兴战略的中坚力量,农业高校的研究生思政教育工作更具紧迫性和艰巨性。文章在考察我国“立德树人”思政教育理念历史发展脉络的基础上,阐述了新时代农业高校研究生培养的时代使命,并以中国农业大学为案例,分析了当前农业高校新时代思政育人的基本路径在于:实现“隐性教育与显性教育”的有机结合、“请进来与走下去”的有机结合、“线上和线下并行”的有机结合,以此使立德树人潜移默化地融进研究生教育的各个环节,提升学生的素养,培养爱国爱农的情怀。文章认为,这将成为助力人才培养质量的优化升级和农业高等教育事业发展的新常态。 相似文献

长角广腹细蜂生物学特性的研究 总被引:2,自引:0,他引:2
长角广腹细蜂Amituslongiconis是湖南茶区黑刺粉虱初龄幼虫的优势寄生蜂。在室内,长角广腹细蜂1a可繁殖5代,在茶园中,1a可繁殖4代,各代羽化高峰期分别在5月下旬、7月上旬、8月中旬、9月下旬。在29~32℃温度下,用蜂蜜饲养的雌成蜂能存活5~6d;不喂蜜的,只存活3d。孤雌产雄生殖。对该蜂的羽化日节律、交尾、寿命、产卵等也进行了观察。 相似文献

The yellow-shouldered parrot (Amazona barbadensis) is listed in Venezuela as Endangered and internationally as Vulnerable, primarily due to poaching for the illegal pet trade. Various interventions have been implemented to reduce poaching (increasing the population from 700 in 1989 to 1600 in 2009), but poaching pressure is still high, and is ever-changing, requiring an evolving response. Between 2000 and 2003, our only intervention was environmental education in schools: in the short term, unsurprisingly, it had no impact on poaching, which reached 100% of nestlings in monitored nests. From 2004 onwards, we implemented a set of new field interventions. In 2004, 24 h field surveillance decreased poaching to 56%. In 2005, the addition of foster nests and a pilot test of “assisted breeding” brought the figure down to 18%. In 2006, assisted breeding was expanded, achieving 0% poaching. In 2007, poachers raided our “secure” site, and took 34 nestlings, bringing poaching up to 60%. A pilot study of artificial nests offered promising results. In 2008 and 2009, the addition of patrolling by local police reduced poaching to 16% and 1%, respectively. During 2004–2009, nestling poaching averaged 25%. Ensuring parrot recruitment in the future will require a combination of the strategies employed to date; in the short term, expanding the use of artificial nests to increase availability of nesting sites in easily-patrolled areas has the most potential to build on past successes. 相似文献

[目的]筛选木霉的培育条件,同时对木霉对农药的敏感性进行研究。[方法]以木霉TC、TY、NF9、PZ株系为材料,先在PDA培养基和玉米培养基中筛选出合适的培养基,再对瓶装培养中的透气条件和袋装培养中培养条件进行筛选,最后进行木霉与农药甲霜灵、百菌清、菌核净间的敏感性试验。[结果]PDA培养基更有利于3种木霉株系的产孢;瓶装培养中透气塑料纸密封能促进木霉产孢;袋装培养中木霉在温度24(±2)℃、光暗比9 h∶15 h或10 h∶14 h的条件下生长较为理想;木霉对甲霜灵的敏感浓度可达1 500 mg/L左右。[结论]为后续的抗性试验提供了数据支持。 相似文献

以云南罗平县、寻甸县、东川区选取的80个农户问卷调查数据为基础,采用A-F方法定量分析了农户的多维贫困现状。结果表明:8个贫困指标导致的单维度贫困发生率从高到低为生活水平、生产资源、收入、健康、教育、政治参与度、卫生设施、家庭资产,1~7维度导致的贫困发生率分别为93.75%、83.75%、43.75%、27.5%、10%、3.75%、1.25%,而生活水平维度(尤其是住房条件)和生产资源维度对多维贫困的影响贡献率最大。据此提出扶贫工作应围绕多个维度展开,且要有所侧重,才能使农村贫困人口真正实现脱贫实现。 相似文献

培育间伐——森林经营的新理念 总被引:1,自引:0,他引:1
培育间伐,不仅是人为促进林木自然稀疏、加快目的树种生长、提高林木生长量的过程,而且是重视森林的整体性、对森林资源全面培育和开发利用、实现整个森林生物群落繁荣的途径。 相似文献
