浅析基层治理中农村社会纠纷的防治

从外延看,当前社会风险涵盖经济、政治、文化、社会、环境以及国际环境等,是一个广义的概念。本文的社会风险特指社会领域存在的风险。社会纠纷作为社会风险的重要组成部分,不可忽视。本文以山西农村社会风险为例,对目前农村社会纠纷进行研究,以求实现更好的纠纷治理,促进农村社会可持续发展。     

5%精禾草克乳油防除农田土人参田稗草效果试验总结

农田土人参完全展齐叶,稗草叶令4~5片叶时,于人参行间定向喷施5%精禾草克乳油防除田间稗草效果显著,防效可达90%以上。化学防除稗草不仅对人参生长无副作用,具有安全性,而且还可以降低劳动强度,达到节本增效目的。本试验条件下,10ml5%精禾草克兑水3000ml施药剂量综合效果最佳。     

应用纳米磁珠实时荧光定量PCR方法检测番茄黄化曲叶病毒

In order to develop a rapid, sensitive and specific qPCR assay for detection and quantification of Tomato yellow leaf curl virus (TYLCV), a pair of primers and TaqMan probe were designed according to the conserved sequence of known TYLCV isolates. Combining with MNP technique, a novel MNP-qPCR detection method was established and verified based on specificity, sensitivity and reproducibility tests. The results indicated that the Ct value of plotted standard curve showed good linear relationship(R² =0.9994)with the log of copy number of template. The established method showed a high specificity for TYLCV detection without crossing reaction with Tomato severe leaf curl virus and Tomato yellow leaf curl Sadinia virus, and was 10-fold more sensitive than routine PCR. Both coefficients of variation were less than 2%, indicating a good reproducibility. We have provided a novel method for detection of TYLCV in plant samples rapidly and quantitatively.     

多抗红果番茄新品种FQ310

<正>番茄是设施栽培主要蔬菜种类之一,近年来设施栽培番茄病害发生越来越严重,尤其是番茄黄化曲叶病毒病(简称TY)、灰叶斑病、"死棵"等病害。实际生产中对相应病害进行药剂防治是控制病害的途径之一,但会增加生产成本,影响番茄品质,因此选育多抗番茄新优品种是解决上述病害的根本途径。四川种都高科种业有限公司一直致力于高端     

6种无公害农药对蒙古栎栗实象的防治效果

[目的]筛选出能有效控制蒙古栎栗实象的无公害药剂和施药方式.[方法]采用6种无公害农药对蒙古栎栗实象成虫分别进行室内筛选试验和野外防治试验,同时对施药方法进行了评估.[结果]室内药剂测定试验结果表明,稀释100倍的1.2％阿维菌素、稀释100倍和500倍的5％噻虫啉及25％灭幼脲致死率均达到70％以上,其中稀释100倍的5％噻虫啉效果最佳,120 h后致死率达到84.21％;室外药效试验结果表明,稀释100倍的25％灭幼脲采用打孔注药的施药方式效果最明显,橡实被害率为64％,降低了32％的果实被害率.[结论]试验结果为蒙古栎栗实象的无公害防治提供了参考.     

长白山区菌棒出榛蘑仿生栽培技术研究

榛蘑为真菌蜜环菌的子实体,是东北地区广泛分布的一种食药用菌,也是迄今为止为数不多的被人们所认知但还没有实现商业化栽培生产的野生菌类。靖宇县农业技术推广中心历经4年时间开展了利用菌棒栽培榛蘑的实验取得成功,一次栽培多年收获受益,既为食用菌增加了新的栽培种类,也为农民开辟了一条新的致富道路。
