- 描述：Under the background of “Internet+ agriculture”, the construction of modern agricultural indus-trial system and the development of intelligent agriculture have become a widespread concern of the government and society. At present, the domestic exploration of smart agriculture pays attention to the field of technology, and there is a lack of relevant research on its adaptive mechanism and development mode. Fusion is adopted in this paper, on the basis of production research innovation to promote the development of intelligent agriculture research perspectives, starting from Hefei wisdom valley agricultural instance, three spiral of economic theory, and based on the analysis of government paper production operation mode of the cooperative mechanism and cooperation basis, in research to explore the administration production coordination mechanism for realistic meaning for agricultural development in our country. At the same time, it will be popularized and applied to agricultural production nationwide to promote the transformation and upgrading of domestic agriculture and accelerate the realization of agricultural modernization and rural revitalization.

- 描述：化肥投入是农业生产最基础的亦是农民最重要的物质资源投入,化肥产业的平稳健康发展,是维护我国未来粮食产业安全的基础,是保证世界农业均衡发展的坚强基石。当前,我国农业生产建设与农业资源环境的矛盾日益突出,化肥行业仍面临着社会能源、资源和环境保护的硬约束。随着农产品供给侧结构性改革的加速推进,节能和清洁环保要求的快速提升,特别是随着政府2015年“化肥零增长”计划要求的提出,为我国化肥需求缺口设置了一个“警戒线”。更重要一点是,人民生活水平快速提高,城乡居民对高品质农产品的需求大幅提升,对肥料产品等一些主要农业投入品的综合品质要求也一定会越来越高。S化肥有限公司是以研发生产销售复合肥料、微生物肥料及其他新型肥料为主营业务的民营企业,是本地化肥行业的头部企业。但当下整个化肥行业产能依然严重过剩,产品间同质化较严重,行业集中度较低,国内外农资市场间竞争日趋激烈,企业持续盈利能力亦大幅下降。传统单一营销模式已经不足以成功应对行业眼下严峻的竞争形势,公司转型升级的任务十分之紧迫,必须通过企业营销管理体系全面变革,积极主动面对和化解产能过剩问题,重新制定一套行之有效的营销策略迫在眉睫。本文力图在理论结合实际的基础上,通过运用PEST模型、波特五力模型、SWOT分析法,对S化肥有限公司的当下营销环境、竞争环境及自身的优劣势、面临的机会和威胁,有了充分的认识。并通过调查与访谈,找出公司现行营销策略存在的问题,再以STP三要素对该企业复合肥产品进行细分定位。根据理论分析和调查结果,结合目标市场需求从产品、价格、渠道、促销四方面制定营销策略,从企业制度、资金、人才、技术方面提出实施营销策略的一系列保障措施。希望能在提高S化肥有限公司市场竞争力的同时,也为其他化肥企业提供参考和应对思路。

- 描述：【Objective】Rational fertilization and adoption of soil amendment is one of the ways to improve acidic soil and reduce fertilizer.By studying the effects of phosphorus potassium nitrate compound fertilizer combined with Calcium oxide conditioner on vegetable yield,nutrient absorption and utilization and soil pH,so as to determine the optimal fertilization scheme for acidified vegetables.【Method】Four treatments were set up in the experiment:(i)Conventional fertilization(CK);(ii)Tianji Conditioner(CT);(iii)Tianji Phosphate Potassium Nitrate Compound Fertilizer(CY);(iv)Tianji NPK Compound Fertilizer + Conditioner(CYT),the changes of yield,biomass,nutrient absorption and utilization and soil pH value of cauliflower and pickled mustard tuber were studied under different fertilization treatments.【Result】Compared with CK,under the condition that CYT treatment reduces the fertilizer application amount by 25 %-33.3 %,the yield and biomass of cauliflower and mustard tuber were increased significantly(P<0.05); The cumulative uptake of nitrogen,phosphorus and potassium in cauliflower was significantly increased by 20.19 %,28.38 % and 25.93 % respectively.(P<0.05); The apparent utilization rate of nitrogen,phosphorus and potassium was significantly increased by 15.77 %,18 % and 64.06 %,respectively(P<0.05); The cumulative uptake of nitrogen,phosphorus and potassium in mustard tuber products increased significantly by 19.17 %,28.82 % and 20.1 %,respectively(P<0.05); In addition,the soil pH was increased by 0.7 and 0.3 units when mixed with potassium phosphate nitrate compound fertilizer and conditioner; The content of exchangeable calcium in soil increased by 28.9 % and 42.6 % respectively; The exchangeable acid content of pickled mustard decreased by 2.13 % and soil acidification was improved.【Conclusion】Phosphorus potassium nitrate compound fertilizer combined with calcium oxide conditioner can increase vegetable yield,fertilizer apparent utilization rate,soil pH and exchangeable calcium content,and reduce soil exchangeable acid content.Therefore,the application of calcium oxide conditioner in the compound fertilizer of phosphorus and potassium nitrate in purple soil area of Chongqing is an effective way to reduce the amount of fertilizer applied in farmland and adjust soil acidification.

- 描述：Geotechnical properties have strong regional characteristics, so it is of great significance to identify their regional characteristics for local engineering construction. In this paper, taking the soft clay foundation near the Maanshan River as an example, taking the muddy silty clay as the research object, the buried depth of the muddy silty clay in the research area is shallow, and the soil layer is thick. It is of great significance to find out the physical and mechanical indexes of the soft clay foundation in this area for engineering construction. Based on the statistical analysis of the physical and mechanical indexes of the soft clay foundation soil near the Maanshan River, it is found that the muddy silty clay is 14 m thick, and the physical and mechanical indexes change little with the depth of the soil layer. It is also found that there is a good linear correlation between the physical and mechanical indexes of Maanshan bulk materials. The physical and mechanical indexes of mucky silty clay in the foundation soil of Ma’an bulk material site are significantly correlated, among which the physical indexes are well correlated, especially the linear fitting of void ratio, water content, plastic limit, liquid limit and natural gravity, with the correlation coefficient R2 greater than 0.9. There is some variability in mechanical indexes, but the correlation between mechanical indexes and physical indexes is good, especially the correlation between void ratio and compression coefficient, unconfined compressive strength and cohesion.

- 描述：With the rapid development of urbanization and industrialization in China, a large number of pollutants are discharged into the water, and the problem of lake sediment pollution is becoming more and more serious. In order to reflect pollution status of sediments in Chaohu Lake, in the present study, forty-seven surface sediment samples were selected to analyze REE concentrations, further to estimate spatial distribution, REEs fraction, Ce-anomalies and Eu-anomalies, and potential contamination sources. Results are shown as below: the average concentration of REE in Chaohu Lake was found higher than the background value. REEs show right-tilting pattern and ΣLREE significantly enriched. ΣREE was found higher in the eastern Chaohu Lake; however, a higher level of REEs fraction was found in the western Chaohu Lake, which means extensively anthropogenic activities.

- 描述：降雨径流是引起土壤侵蚀的主要动力,因此预测不同降雨及下垫面条件下的径流量是土壤侵蚀预报和水土流失治理的关键。应用美国原水土保持局开发的流域水文模型SCS-CN模型对巢湖流域降雨—径流过程进行模拟。在ArcGIS 9.2软件支持下,估算2002—2006年巢湖流域地表年径流量并分析了不同土地覆被类型的产流状况。结果表明,巢湖流域地表降雨径流年际变化较大,径流量变化范围为591.323～1 557.136mm。不同土地覆被类型产流能力依次为:城镇用地>水田>未利用地>旱地>农村居民点>草地>林地>灌木林。
- Revisiting the Exchange between Zhuangzi and Huizi on Qing

来源：关键词：Wuwei 無為 Qing 情 Wuqing 無情 Shifei 是非 the Zhuangzi 莊子
- 描述：In this article we focus on the famous dialogue between Zhuangzi 莊子 and Huizi 惠子 concerning the question whether or not ren 人 (in particular the shengren 聖人) have qing 情. Most scholars have understood qing in this exchange as referring to “feelings” or “emotions.” We take issue with such readings. First, we demonstrate that, while Huizi probably understands qing as something like feelings or emotions, Zhuangzi’s view is that having qing is connected with making shifei 是非 judgments whereas having no qing means that shifei has no grip on those ren , especially the shengren . What follows is that the expression wuqing 無情 should not be identified as a “doctrine of nonemotion.” Instead, wuqing implies that Zhuangzi advises us to lead a life of tranquility, calmness, and stillness. We show that these peaceful attitudes are associated with the idea of wuwei 無為 in the Zhuangzi .
