冬枣绿盲蝽成虫毒力测定与防治方法研究

通过室内和田间试验,比较了14种不同农药对冬枣绿盲蝽成虫杀伤力的差异。筛选了4种对冬枣绿盲蝽成虫具有较好杀灭作用的农药。室内试验结果表明:在14种农药中,对冬枣绿盲蝽成虫具有较好杀灭效果的有敌敌畏、氰戊菊酯、甲氰菊酯和氟虫腈。其中氟虫腈效果最好,LC50为81.57μg/g,其次为敌敌畏和氰戊菊酯,LC50分别为232.58μg/g、291.28μg/g。而大田试验,各种农药的防治效果较差。采用叶片喷雾法,5%氟虫腈乳油1000倍与20%甲氰菊酯乳油800倍防治效果最好,分别为65.94%、64.24%。土壤处理,基本无法控制成虫危害。因此必须采取多种方法才能有效控制绿盲蝽的危害。

日本环境保全型耕地农业系统对中国耕地保护的启示

为解决中国农业长期粗放经营问题,研究中国耕地与生态文明协同保护体系,采用文献研究法和归纳演绎法,分析东亚地区代表国家环境保全型农业下的耕地农业协同体系。研究表明,日本的耕地农业环境保护支付制度、生态补偿市场认证体系、耕地农业法律制度保障,是建立在生态补偿原则上,经过实践检验行之有效的,能够提升市场参与度及农民自主性投入的耕地生态协同保护措施。中国在推广耕地合理利用实践方面做出了不懈努力,但是在建立耕地生态协同保护的休耕制度、因地制宜建立生态补偿体系、加快推进耕地生态协同保护专项基金的设立等方面还需进一步坚持和完善。     

A Multi-agent Fault Diagnosis System of Rotating Machinery Based on CBR

Recently,distributed intelligent systems based on multi-agent have been applied to many fields successfully.the multi-agent technique is introduced into the rotating machinery fault diagnosis system.With the combination of CBR technique,Basalstructure and development approach of the system are analyzed,and better cooperation among agents is realized.As a result,the system overcomes the limitation of single fault diagnosis method,and solves the contradictionbetween versatilityand adaptabilityof diagnosis software.Furthermore,a reference can be used for the research and development of multi-algorithmdiagnosis system of rotating machinery.The application in a factory's Networked Online Monitoring and Fault Diagnosis System for Turbine Fan shows that the system can diagnosefault rapidly and exactly.     

Work-hardening Mechanism of Non-magnetic High Manganese ZG25Mn18Cr4 Castings

The important character of non-magnetic high manganese ZG25 Mn18Cr4 alloy is rapid work-hardening under external stress. With X-ray diffraction and TEM analysis, it is proved that the microstructures of both undeformed and deformed matrixes are austenite and carbide with some striation structure in the matrixes, the amount of stripes in the deformed matrix is obviously more than that in the undeformed matrix. Electronic diffraction analysis confirmed that the stripes in coarse austenite grains are high density lamination fault sheets. A great deal of lamination fault sheets produced by plastic deformation divides up austenite matrix, shortens the free distance of dislocation movement and results in the rapid work-hardening of ZG25Mn18Cr4 alloy.     

转反义TRX s基因对小麦萌发过程中储藏蛋白降解的影响

以转反义TRX s基因豫麦18和对照（豫麦18）为试材，测定了小麦种子萌发过程中胚乳内thiocalsin、苹果酸脱氢酶、谷丙转氨酶的活性以及游离氨基酸含量的变化。结果表明，反义TRX s基因的导入能够增加对thiocalsin和苹果酸脱氢酶的抑制，降低其活性，使储存蛋白更难于被降解，谷丙转氨酶增高的速度减慢，种子氨基酸代谢减弱。说明蛋白质代谢缓慢是转反义TRX s基因小麦抗穗发芽的一个主要原因。     

两用核不育系广占63S和籼粳型父本配组其F1 产量性状与产量的关系

利用光温敏两用核不育系广占63S分别和籼粳型父本测交配组，通过对两种类型F1代的产量性状表现的比较，对两种组配方式32个F1组合的单株产量与产量性状的关系进行相关分析，并对产量性状对单株产量进行了通径分析。结果表明，广占63S与籼型父本配制的组合在结实率和千粒重上优势明显，其单株穗数和单株产量呈极显著正相关，结实率和单株产量呈显著正相关；粳型父本配制组合的结实率和单株产量呈极显著正相关，每穗粒数和单株产量呈显著正相关。两种组配方式后代组合产量性状对单株产量的直接作用也不相同，进而提出了利用广占63S与籼型材料配组比直接利用粳型材料配组更有利于选育出强优势实用型杂交组合。
