中国蔬菜的表现——油菜花31在埃塞俄比亚

一、Performance of Chinese vegetable—Sweet Rape Flower 31 in Ethiopia(论文文献综述)

DEMEKE ZEM ENE SHI FERAW[1](2014)在《Ethiopian Trade Relations with China: Achievement, Challenges and Prospects》文中提出The main objective of this study was to examine post1991Ethiopian trade relationswith China, the main focus being on achievements, challenges and prospects.Ethiopia needs China for economic cooperation including trade relation. It cannot allin all depend on the western countries. China’s development experience is generallyconsidered as a role model for Ethiopia to adopt. Moreover, China supports Ethiopiaon different economic issues like aid and soft loan. On the other hand, there are alsoseveral factors pushing China to look towards Ethiopia especially in terms ofEthiopia’s strategic importance and market potential. After the critical analysis oftrade data between Ethiopia and China, this paper empirically proved that Ethiopiaincurs huge deficit in its trade balance with China in the period from1991onwards.The result from cross sectional data sources, i.e. secondary sources, and officialreports, reveal that Ethiopia’s export to China is much less than its imports fromChina. Although trade figures show that there are improvements in the Ethiopia’sexport, the trade balance is still largely in favor of China. Dependence on the exportof few unprocessed agricultural products, weak export performance and geographicfactors are among the reasons for the Ethiopia’s trade deficit.The researcher also provides practical policy recommendations such as: preferentialtreatment to be fully exploited by Ethiopia; leveraging China’s investment in SpecialEconomic Zones; encouraging joint venture between Chinese and Ethiopian firmsamong others.

CAMARA MOUSSA(王穆沙)[2](2012)在《关于几内亚农业政策对扶贫和粮食安全影响的评估》文中指出由于实行第二共和国政府所推行的各种投资方案,近年来几内亚农村地区经历了深刻变化,现在是一个充满活力的部门。鉴于有利于地区气候调节的巨大农业潜力,几内亚农业政策主要选择从温饱型农业走向市场型农业。关键农业与粮食生产部门的能力是,调动私营部门在农村社区可持续发展中多样化积极性的基础。对减贫与粮食安全影响的更好评估,需要可靠的统计数据,并需允许客观看待农业部门更好决策和经济政策。几内亚农业被视为经济发展的基本来源,它占用80%的劳动力,并且很大程度上由占全国95%耕地的家庭农场占主导地位。这些耕地的大小各不相同,从0.30至0.50公顷。农业结构变化来自于农民的多样化活动,反过来,是创造财富、创造农村新风光的潜在来源。这些因素突出了农业部门的整体发展,并且需要发展适应新制约因素,集合所有利益相关者新需求的农业数据库。尽管自1988年农村人口普查以来,努力组织与实施不同农业数据调查,但是对于几内亚农业发展政策新战略方向的要求来说,信息需求的覆盖范围依然非常有限。在国家人口普查建议使用的1996年到2005年联合国粮食与农业组织2000年世界农业人口普查的框架下,从充分发展国家与地区层级主要农业事件完整和相关信息角度,几内亚进行了2000到2001年全国农业人口普查。实现部门最高生产力水平取决于生产要素的使用,包括开始使用肥料,改良种子和农药,进行农业机械化打开建立大型农场和现代农场之路。与我们的农业发展前景相比,今天利用这些因素非常重要:(一)只有20%的地块使用机肥和/或矿物质,(二)95%的地区己使用非本地种子选择传统农场,(三)农业控股主要使用传统手工制作,(四)95%的地区只有2%的农业使用雨水灌溉。因此,尽管产量高,提高生产力仍然是一个挑战。实施增加农业投入和逐步融入机械化政策方可调动生产潜力,增加农民收入,确保国家粮食安全和减少贫困。极端贫穷和脆弱性仍然是阻碍发展的关键因素,最近的几次已经引起了几内亚政府的注意。然而,尽管使用激进的农业政策措施,许多农村地区仍然须继续克服贫困及粮食安全。农业是家庭的主要活动和主要收入来源,农民的贫困率大约为63%。几内亚实行的农业主要为温饱型农业,生产产区一般较低(0.30到0.50公顷),在这种情况下,产量和销售能力不是很高。这些结果明显表明需要重点发展农业和农村以快速减少贫困。为了更好地理解农业政策在减少贫困方而的作用,从2010年8月到2012年2月,由63个农民联盟组织的调查小组对21个县进行了调查。虽然没有结构式问卷收集全面信息,使用检查单作为从不同类别的人群中(既有农村的也有在办公室的)讨论问题与获取信息的指南。使用与研究相关的附加信息来分析收集到的数据,包括:农业人口、农业劳动力、耕种地区、农业生产、供应、支持交易、培训农产品加工、农民联盟的收入、农村居民职工的收入、农场设备和基础设施。对收集的数据使用理查森的外推估算法来分析。经确认三个互补方法可以提高农民生活条件:(1)支持的供应和生产;(2)支持营销,(3)支持农民组织。因此,政府制定的农业政策为实现这一目标应最大限度使用生产要素;加强农业活动与多元化农业活动,将发展经营落实到位(非政府组织支持的农业项目)。本文提出一种农业政策的社会经济分析农村地区的改进几内亚和前景农村居民的生活条件。该农业政策通过以下策略支持农民联盟:N。l策略:通过多样化与提供食品产量推进粮食主权来提高粮食安全;N。2策略:在反贫困方面,通过经济发展机会与提高市场准入来提高农民农场收入;N°3策略:保证投资效率的发展措施。这些策略已提高农村居民的生活水平。此外,河南的农业政策为便于研究提供了一个榜样。该政策亦通过以下策略支持农民:(a)粮食安全与粮食自给自足,(b)提高农民收入,和(c)贸易自由化与融入世界市场。本文对几内亚农村地区的农业政策进行了社会经济分析,并且预期了改善农村居民居住条件的前景。

蔡鸿娇[3](2007)在《间作套种对小白菜田节肢动物群落及主要害虫的影响》文中指出在化学农药产生之前,间作套种是害虫防治的主要手段之一。由于化学农药所产生的一系列弊端,人类开始寻找安全有效的控制措施。近年来,许多昆虫学家和生态学家根据他们的研究工作,认为通过采用合理的耕作制度和栽培措施,可以保护和强化农田生物多样性,恢复和重组农田生态系统的动态平衡,有利于农业害虫的生态控制和综合治理(Andow,1991;Altieri,1987,1994;Douglas等,2000)。因此,利用生物多样性控制作物虫害已成为当前的一个研究热点。本文从群落生态学的角度出发,研究不同作物间作套种对节肢动物群落天敌功能团的影响,旨在揭示多样化生境对保护和利用自然天敌生态学机理,为菜田害虫的持续控制提供理论依据。同时观察测定间作套种下对小白菜新陈代谢、对小菜蛾生长发育和三种农药相关酶系的影响。1.间作套种对小白菜田节肢动物群落的影响2004年于福建省琅歧经济开发区调查间作套种对菜田节肢动物群落的影响,间作套种系统分别为大蒜间作小白菜(CG1),大蒜套种小白菜(CG2),春菜间作小白菜(CL1),春菜套种小白菜(CL2),包菜间作小白菜(CB1)和包菜套种小白菜(CB2),以单一种植小白菜为对照(CK)。调查结果显示:(1)共采集到53392头个体,包括昆虫纲、蛛形纲和多足纲,经鉴定分别属于98科,111属,175个物种。整体上,单作田和多作田之间目、科、属之间差异不显着,但是科总数,多样性和均匀性指数,单作田明显低于多作田,差异显着。CL1与CL2群落相似性最高(0.71),相似性最低为CB2与CK(0.10)。(2)根据各个功能团划分,捕食性功能团物种数最高(59种),占总物种数的33.71%,而中性昆虫物种数最低(27种,15.43%)。各功能团丰盛度依次为:中性昆虫(占总个体数的62.13%)>植食者(27.24%)>捕食者(6.79%)>寄生者(3.84%)。其中,单作田中性昆虫数量明显高于多作田。(3)整体上多作田植食者的物种丰富度高于单作田,丰盛度最高为CG1和CB1。多样性指数,除了CG2,其它各个多作田均明显高于单作田。CL1,CB1和CK优势度指数没有显着差异。CB1,CB2和CK田内小菜蛾种群动态相似;黄曲条跳甲种群数量多作田低于单作田:蚜虫在生长前期多作田低于单作田,但生长后期高于单作田。(4)寄生性昆虫物种丰富度依次为CL1(33种)>CG1(32种)>CG2(27种)>CL1(26种)>CK(23种)>CB2(21种)>CB1(20种)。寄生者数量最高为CG1,CG2和L2,明显高于CK。多样性指数多作田明显高于单作田;但是均匀性和优势集中性指数多作田和单作田之间没有显着差异。其中,从第16天到第32天多作田蚜小蜂数量明显高于单作田。多作系统比单作系统支持更多的菜蚜茧蜂。(5)捕食功能团,物种丰富度最高为CG1,最低为CK,个体数量最高的为CG1(141.67头/小区),最低为(97.67头/小区)。多作田除CL1多样性指数均显着高于单作田。CL1均匀性指数显着低于其他各田,多作田的优势集中指数明显高于单作田。所采集的捕食者中,大部分属于蜘蛛类,其中球腹蛛科占34.04%,狼蛛占30.57%。CG1,CL1和CB1的狼蛛数量在各调查时间内均高于单作田。(6)单作田的中性昆虫数量,及优势集中性指数显着高于多作田;单作田物种数、多样性、均匀性指数显着低于多作田。丰盛度最高的物种为跳虫科,占87.35%,紧接着为双翅目昆虫。CK和CB2田的双翅目昆虫较少。本实验说明小白菜与非十字花科作物间作套种有利于提高天敌(包括捕食性和寄生性天敌)的多样性和丰盛度。多样化种植对天敌的影响比对植食性昆虫的影响更大。2.间作套种对小白菜新陈代谢的影响研究小白菜分别与春菜(CL)和大蒜(CG)间作套种下对小白菜各个生理生化指标的影响,包括总蛋白,可溶性糖,还原糖、硝态氮、叶绿素含量,并测定了4种酶活性,分别为硝酸还原酶(NR)、过氧化物酶(POD)、过氧化氢酶(CAT)和超氧化物歧化酶(SOD)。结果显示间作套种显着提高可溶性蛋白和硝态氮含量,春菜与小白菜(CL)套种明显提高小白菜生长后期叶绿素a的含量。总体上,间作套种对可溶性含量没有影响;还原性糖含量随着生长期的不同而变化。大蒜和小白菜套种显着提高NR、SOD和CAT酶活力。春菜与小白菜套种显着提高SOD,POD和CAT活力。本实验为小白菜与非十字花科作物间作套种提高植物营养水平和植物代谢水平提供了理论依据。3.间作套种对小菜蛾生长发育的影响研究小白菜分别与春菜(CL)或大蒜(CG)间作套种下对小菜蛾5个世代的生长发育历期、蛹重、成虫羽化率、产卵量以及卵孵化率的影响,以小白菜单作田(CK)饲养下的小菜蛾为对照。结果显示:春菜与小白菜间作套种显着延长小菜蛾各个世代幼虫生长发育历期,大蒜的影响达3个世代(F1,F4和F5)。化蛹率(88%-91%)三者之间没有显着差异,但是CG明显提高了小菜蛾3个世代(F3,F4和F5)的蛹重(平均5.20 mg/蛹),而单作田为(平均4.60 mg/蛹)。CG和CL均显着降低成虫羽化率,分别为92%和77%,对照为96%。各个世代的产卵期和产卵量表现出不稳定变化。CG和CK卵历期没有显着差异,为2.4—3.5天,但是CL比CK显着延长了小菜蛾3个世代的卵历期(F2,F3和F5)。因此,合适的间作套种可通过延长小菜蛾发育历期,降低羽化率、卵孵化率或产卵量来降低每年的世代种群。4.间作套种对小菜蛾三种解毒酶活性的测定测定小白菜分别与大蒜和春菜间作条件下对小菜蛾3龄幼虫的三种解毒酶乙酰胆碱酯酶(AChE),羧酸酯酶(CarE)和谷光甘肽S转移酶(GST)的活力影响。结果表明:与单一种植田小白菜比较,小白菜间作明显降低了小菜蛾三种酶活力,说明间作套种可推迟小菜蛾对有机磷、氨基甲酸酯类和拟除虫菊酯类农药的抗性产生速度。
