以磷定氮条件下施氮处理间的无效性与抛物线函数的误用

在以磷定氮田间试验结果的基础上,应用抛物线回归方法确定作物最高产量施肥量。该方法是国内外定量施肥研究的基本方法,但其试验统计结果确定的施肥量与用抛物线回归方程求解的作物最高产量施肥量严重背离。为了探明二者背离的原因,自2004年以来,在玉米和谷子上进行了试验研究,结果表明,传统以磷定氮试验方法试验设计中未考虑施肥比例对作物产量的影响,结果导致施肥处理间产量统计检验不显著,形成抛物线回归分析方法的误用,致使确定的作物最高产量施肥量失去科学性。     

中国大学英语学习者中介语动词结构陋用之管窥

对二语/外语动词习得的研究通常围绕动词形态的习得顺序来进行,但本文主要从动词和其它词的搭配着手研究中国大学英语学习者英语动词结构的习得。利用两个大型语料库定量对比了cost、survive和adapt三个常用动词在本族语英语和中国大学英语学习者中介语中的使用情况,发现后者中有较严重的滥用、少用和误用现象,以此我们可以管窥大学英语学习者中介语中动词结构的使用特征。导致这一情况的两个主要原因是培训迁移和母语迁移。     

Attitudes towards pesticide labelling among Greek tobacco farmers

Abstract

A survey of tobacco farmers was conducted in the rural area of Pieria in northern Greece to investigate farmers' attitudes towards information given on container labels in respect to pesticide use and safety issues. A large proportion of the farmers (72%) agreed that most information on pesticide labels is hard to read, whereas the vast majority (94%) agreed that most of the information on pesticide labels is hard to understand. More than half of the farmers (63%) reported that they often try to read the labels but do not understand everything featured on them, whereas only a tiny proportion of the farmers (6%) stated that they always read and understand the entire label. Among those farmers who stated that they never read the labels, just over half (53%) reported that it is because they do not understand the information the labels contain, whereas 35% claimed that it is because they already know the information. Two out of three farmers (66%) reported that when buying a pesticide product they mostly pay attention to the directions for use. Few farmers (6%) reported that they pay attention to safety precautions, environmental hazards, and information concerning first aid and antidotes given on the label. Most farmers (57%) reported that when deciding to use a pesticide product they primarily rely on pesticide salesmen's information, while nearly a third (32%) reported that they rely on their own experience. Only a few farmers (6%) stated that they rely primarily on the information found on the product labels. Forty-six percent of the farmers declared that they normally exceed the recommended rates indicated on the label, whereas none reported using less than the label rates. We conclude that essential information about pesticide handling and safety issues found on pesticide labels has to be more effectively communicated to the farmers using appropriate label formats which facilitate noticeability, legibility, and comprehension.
