境外网络游戏的软权力作用分析

境外网络游戏是软权力在文化领域的重要载体之一,正日益凸显其重要地位,大多是通过网络游戏的内容和背景展现出来,意在增加本国经济效益的同时,以达到能够吸引不同国家和地区的更多玩家,灌输和宣传本国的思想和文化,使之成为配合其各国软权力战略实施的双重作用。面对这种新的文化渗透模式,研究如何应对境外网络游戏的隐性影响,是目前研究的主要课题。     

企业文化差异性对企业并购的影响

随着时代迈入21世纪，企业并购频频发生，并且其规模有着越来越大的趋势。然而并购前大量一致被看好的案例，在并购发生后，结果都差强人意。其根本原因在于人们习惯于从企业硬件方面来看问题，而忽略了企业文化（软件）的差异性。本文通过分析企业文化差异性对企业并购的影响，最后提出规避企业文化差异性对并购不利影响的几点建议。     

我国文化体制改革的人本原则

我国文化事业体制和机制的僵化导致了一系列的问题。发展我国文化事业必须坚持“以人为本”的原则，即遵循文化企事业单位和文化市场的发展规律，通过人本身的知识、能力和创新技术创造出文化产品和服务来充分满足人的精神文化需求，从而最终达到人的全面发展。     

氮、磷和钾肥施用量对有机生态型无土栽培温室黄瓜产量影响的研究

采用二次回归饱和D-最优试验设计方法研究了固态N、P和K肥施用量对日光温室有机生态型无土栽培春茬黄瓜产量的影响,建立了N、P和K肥施用量与早、中、后期黄瓜产量形成之间的数学模型.试验结果表明:N、P及K对黄瓜的早期产量影响极显著,产量区间为2 400～3 260 g/小区的最佳施肥量(单位:g/株/次)为N 0.83,P2O5 0.37,K2O 0.86;P、K是影响黄瓜中期产量的主要因素,产量区间为6 400～9 200 g/小区的最佳施肥量分别为N 0.66,P2O5 0.33,K2O 0.90;黄瓜生长后期,N肥对黄瓜产量的影响极其显著,产量区间为2 000～2 940 g/小区的最佳施肥量为N 0.61,P2O5 0.40,K2O 0.94.     

Status of black grass (Alopecurus myosuroides) resistance to acetyl-coenzyme A carboxylase inhibitors in France

We assessed the contributions of target site‐ and non‐target site‐based resistance to herbicides inhibiting acetyl‐coenzyme A carboxylase (ACC) in Alopecurus myosuroides (black grass). A total of 243 A. myosuroides populations collected across France were analysed using herbicide sensitivity bioassay (24 300 seedlings analysed) and ACC genotyping (13 188 seedlings analysed). Seedlings resistant to at least one ACC‐inhibiting herbicide were detected in 99.2% of the populations. Mutant, resistant ACC allele(s) were detected in 56.8% of the populations. Among the five resistant ACC alleles known in A. myosuroides, alleles containing an isoleucine‐to‐leucine substitution at codon 1781 were predominant (59.5% of the plants containing resistant ACC alleles). Comparison of the results from herbicide sensitivity bioassays with genotyping indicated that more than 75% of the plants resistant to ACC‐inhibiting herbicides in France would be resistant via increased herbicide metabolism. Analysis of herbicide application records suggested that in 15.9% of the populations studied, metabolism‐based resistance to ACC‐inhibiting herbicides was mostly selected for by herbicides with other modes of action. Our study revealed the importance of non‐target site‐based resistance in A. myosuroides. Using herbicides with alternative modes of action to control populations resistant to ACC‐inhibiting herbicides, the recommended management approach, may thus be jeopardised by the widespread occurrence of metabolism‐based resistance mechanisms conferring broad‐spectrum cross‐resistance.     

Significance of leaf infection by Botrytis cinerea in stem rotting of tomatoes grown in non-heated greenhouses

The most serious symptom of Botrytis cinerea in tomatoes grown in greenhouses is stem rotting. Lesions on the stem may result from direct infection or from progression of the rot along infected leaves, until infection approaches the stem. In a set of experiments conducted in commercial greenhouses, an experimental greenhouse and growth chambers, the significance of the two types of stem infections was studied. In non-heated greenhouses most of the stem lesions originated from progression of the pathogen along infected petioles. The rate at which B. cinerea had progressed on infected petioles was 0.3–0.5 cm/day, an average of ca. 6 weeks was needed for a leaf infection to approach the stem. Application of Trichoderma harzianum T39 extended this time by 1–2 weeks and application of chemical fungicides by 3 weeks. Influence of the environment on the progression of B. cinerea along infected petioles was then determined. Within range of 5–30 °C, the higher the temperature, the more rapid was the rate of disease progression. The fungus progressed more rapidly on tomato petioles incubated at high vapour pressure deficit (VPD) rather than at low VPD. The source-sink relationship of the plant governed the rate of B. cinerea progression along the petioles as well: it was more rapid when the source was restricted (by shading) and slower when the sink was restricted (by removal of flowers and small fruits). The possibility that sanitation of infected leaflets would reduce the incidence of stem rotting was examined in two experiments. In plots not treated with a fungicide, the sanitation treatment substantially decreased the incidence of stem lesions and this treatment was as effective as weekly application of chemical fungicides.

超级稻Y两优2号在三亚高产栽培技术探讨

Y两优2号是国家杂交水稻工程技术研究中心选育的超级杂交稻新组合，2011年创造了世界较大面积产量最高纪录13.9 t/hm2。该组合根系发达，分蘖力较强，穗大粒多，结实率高，具有株叶形态理想、熟期适中、适应性广、高产稳产、优质多抗等特点。2011～2012年在海南省三亚市种植，实际产量为11.74 t/ hm2，达到了该生态条件下产量的超高产水平。本文基于水稻叶龄模式和水稻高产群体质量指标，从精确定量施肥、科学湿润灌溉等方面对高产栽培技术作了阐述。从播栽期、培育壮秧、合理基本苗、行株距、施肥、水分管理等方面进行了Y两优2号栽培技术的精确定量。提出Y两优2号超高产栽培应在协调穗、粒、重发展的基础上充分发挥该品种分蘖力较强、穗大粒多的优势，采取前期尽早攻穗，中后期增粒、保重的栽培策略。
