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。

An evaluation of the Olsen test as a measure of plant-available phosphorus in grassland soils derived from basalt parent material

Abstract. Anecdotal and circumstantial evidence have suggested that the Olsen test underestimates plant-available phosphorus (P) in basaltic soils in Northern Ireland. Therefore, the ability of this test to predict plant-available P in basaltic (and non-basaltic) soils was investigated by regressing Olsen-P data against herbage P indices calculated from plant tissue test data using the diagnosis and recommendation integrated system. The average Olsen-P concentration for a range of fields situated on basaltic soils was considerably lower than the average Olsen-P concentration for a range of fields situated on non-basaltic soils, and yet mean sward P status, as given by the herbage P indices, was similar for both groups of fields. Herbage P indices were also much better correlated with Olsen-P measurements in non-basaltic soils than in basaltic soils. Furthermore, at low Olsen-P values (≶9mgPL⁻¹) some swards on basaltic soils were genuinely deficient in P, while others were sufficient or even in surplus for this nutrient. The results confirm that Olsen-P is inadequate as a predictor of plant-available P in basaltic soils. It is concluded that an alternative soil test is needed to provide a reliable assessment of plant-available P in basaltic soils, to prevent overuse of fertilizer and manure P and to minimize the amounts of P entering local watercourses.     

运用模糊数学和灰色系统理论分析评价夏播花生区试品种

运用模糊数学和灰色系统理论，对2007年河南省夏播花生区试品种进行了多因素综合评价和分析，结果表明：周花4号评价指标是0．7089，综合表现最优；其次是W9847—1—3—4—1，其综合评价指标是0．6352；豫花6号评价指标是0．3630，综合表现最差。此结果与试验地实际表现基本相一致。     

完善农村居民最低生活保障制度的几点建议

当前，我国农村普遍建立了居民最低生活保障制度，这是保障农村社会稳定的“最后一道安全网”，是中国农村社会保障体系的基础工程。但是，我国农村居民最低生活保障制度也还存在一些问题，例如保障对象、保障方式、保障资金、管理体制等，充分认识并采取 有效措施解决好这些问题，对于完善农村社会保障体系，维护农村社会稳定和经济发展有着重要现实意义。     

The Phytotoxicity of Various Graminicides in Durum Wheat in Greece

The effect of three herbicides, diclofop-methyl (DM), imazamethabenz-methyl (IM) and fenoxaprop-ethyl (FE), was investigated at the recommended rate (×) and double the recommended rate (2×) in a durum wheat crop. FE had the smallest effect on root system characteristics, while IM had the greatest effect. For all herbicides, the double rate treatment gave a greater statistical reduction than the single rate for root system characteristics. FE had the smallest effect on the activity of aerobic microorganisms, while DM gave the greatest reduction, 10 days after application, and all three herbicides reduced earthworm abundance. DM gave the smallest reduction in the number of tillers and in plant height, while the double rate of IM gave the greatest reduction. For all three herbicides, double the recommended rate resulted in a significant reduction in the weight of 1000 seeds, while no statistically significant deviations were noted at the recommended rate. Finally, the use of all three herbicides resulted in significantly lower statistical yields compared to the sample (control plot), although there were no significant statistical differences among them, for either recommended or double recommended rates.
