应用型本科实习实训教学质量评价体系研究

实习实训是应用型本科院校教学中比较重要的环节,实习实训教学质量评价能够反映出学生在实习期间的诸多情况以及专业导师、企业导师和思政导师的指导情况等。针对现在实习实训体系评价不够完整的状况,本文构建了实习实训教学质量评价体系的标准,建立了相对应的二级指标及比例分配。该体系由实习实训的条件、师资队伍、过程、效果4个部分构成,具有更细化的观测点以及较强的可操作性。     

论我党历史上的三次经验总结及其重大意义

在我党历史上先后有过3次大的经验总结，促进了党的自身建设及理论上的成熟。第一次总结为中国民主革命的胜利奠定了基础；第二次总结找到了有中国特色的社会主义建设道路；第三次总结把党对历史经验的总结提高到一个崭新的高度，为全面建设小康社会提供了有力的保证。     

金针菇品种比较试验

１９９１年１０月至１９９３年７月，笔者用Ｃｏ－２７等１２个菌株做了四批十二次金针菇品种比较试验，菌株Ｃｏ－２７比优良品种三明一号，Ｆ９０８分别增产１４．２６％和１２．３９％，差异显著性测验表明，它们之间的差异均达到了显著程度；Ｃｏ－２６，Ｃｏ－１４，Ｃｏ－２３，Ｃｏ－１５，Ｃｏ－２４，Ｃｏ－１３等菌株与两个对照品种相比，其产量都有不同程度的提高，除Ｃｏ－２５之外，各菌株之间菌丝生长速度没有表现出显     

Landscape-ecological mapping of the Netherlands

The Landscape-ecological Mapping of the Netherlands project (LMN project) started in 1983 with the aim of establishing a landscape-ecological database for use in developing and evaluating national land-use plans. The project, working with grid cells of 1 km², has four working objectives: a) development of mapping potential for basic landscape-ecological data, b) assessment of susceptibility to interventions, c) evaluation of significance for nature conservation and d) production of vulnerability maps, as a combination of susceptibility and significance. In addition to information on soil, groundwater, ecotopes, flora and fauna, the database also incorporates information on physiographical features and entire landscapes. The resulting database is a geographic information system (GIS). This article describes the second phase of the project (1985–1989), covering the Randstad area, and focusses on the methods and the applications potential of the database.     

Recovery of non-target plants affected by airborne bromoxynil-octanoate and metribuzin

The present study was conducted to evaluate the recovery potential of non‐target plants affected by two airborne herbicides. Sunflower at the two‐leaf stage was used as a test plant and exposed for 24 h in a wind tunnel to a range of concentrations of airborne bromoxynil‐octanoate and metribuzin. Quantum yield (φ_PSII) of exposed leaves and of the second leaf pair developed after exposure was determined at a particular time up to 16 days following exposure. Maximum depression in quantum yield of exposed leaves from which a complete recovery occurred within 16 days was 63% for bromoxynil‐octanoate and 60% for metribuzin respectively. The corresponding maximum concentrations were 1.310 and 0.390 μg m^?3 respectively. The second leaf pair was also affected and showed a similar recovery potential. From the results it can be concluded that the significance of airborne bromoxynil‐octanoate and metribuzin must not be overestimated, as sunflower and non‐target plants with a similar sensitivity are likely to recover from air concentrations of both herbicides reported under field conditions.     

浅析科学施肥

林业可持续发展的意义浅析

可持续发展是一种新的科学发展观，已经深入到林业领域。要使森林资源满足当代人的建设需要，又为后代人储备资源，就要实施科技兴林，不断提高林业建设的科技含量，不断促进林业的可持续发展。     

农业人才实践技能的提升策略

随着经济全球化速度的加快,农业产业不断升级,新时代对农业人才质量的要求提高,培养高技能农业人才已成为一个世界性的话题。笔者结合云南省实际,分析了农业人才培养面临的机遇与挑战,从教学缺少创新性,校企合作对接不紧密,办学特色不突出3个方面探讨了农业人才培养的滞后性。重点论述了未来高技能农业人才培养途径,强调要以人为本,创新教学理念,建立完善的校企合作制度,突出本校办学特色,加强实验多学科交叉性与完整性,并采取全程导师制的教学模式。通过对农业人才实践技能提升策略的研究,期望能够对新型优质农业人才的培养建言献策。     

关于林业数学模型中参数的取值问题

针对国内林业期刊文献中普遍存在的数学模型参数取值不规范的问题，提出林业数学模型的参数取值，应遵循小数位统一和有效数统一的原则，而且有效数统一原则应该成为最高准则；同时还对与这两项原则有关的某些特定林业数表模型中参数的取值和估计问题进行讨论。     

酶工程课程改革探索

为了使该课程符合应用型人才的培养目标,培养能从事酶工程相关工作的技术人才,从课程定位、课程内容设置、教学方法和教学手段等方面进行改革,探索合适的教学方法,进一步提高教学效果和人才质量。
