通过田间小区试验,研究氮素和钾素对烤烟的品质化学成分的影响,结果表明:(1)总糖含量与烟叶成熟期土壤有效钾(K)含量呈显著的二次曲线相关性,成熟期土壤速效钾含量分界点为113.33mg/kg。(2)总烟碱含量与施氮量、烟叶含氮量(中期或成熟期)呈显著的相关性。(3)蛋白质含量与施氮量、烟叶含氮量(中期或成熟期)、烟叶含钾量(中期或成熟期)有一定的相关性。(4)施木克值与成熟期土壤速效钾含量呈显著的二次曲线相关性,成熟期土壤速效钾分界点为133.33mg/kg。(5)糖/碱比与烤烟生育前期施氮量和土壤碱解氮,与中后期土壤供钾和烟叶含钾量有一定的相关性。 相似文献

OBJECTIVE: To assess the extent and content of newspaper and magazine coverage of research on passive smoking. DESIGN: Content analysis of newspaper and magazine articles. SUBJECTS: Articles reporting on passive smoking research published in newspapers (n = 180) or magazines (n = 92) between January 1981 and December 1994. MAIN OUTCOME MEASURES: Numbers of articles, conclusions of articles, sources quoted, numbers and characteristics of research studies cited, presence of tobacco advertising. RESULTS: The number of newspaper and magazine articles reporting on passive smoking research increased from four in 1981 to 57 in 1992 and 32 in 1994. Sixty-two per cent (168/272) of articles concluded that the research on passive smoking is controversial. Tobacco industry representatives were quoted significantly more often in newspaper articles (52%, 94/180) than magazine articles (12%, 11/92) (p<0.0001). Of 121 different research studies cited in the lay press articles, only 15 were from tobacco-industry sponsored projects or publications. In magazines, acceptance of tobacco industry advertising was associated with the conclusion that research on passive smoking is controversial (p<0.0001). CONCLUSIONS: Although research on the harmful effects of passive smoking accumulated between 1981 and 1994, lay press coverage of the research maintained that the science was controversial. Few research studies were cited to support the industry's claim that passive smoking is not harmful to health. However, tobacco industry representatives who were critical of the research methods used to study the health effects of passive smoking were frequently quoted. 相似文献

A reply by Edward Lichtenstein to the comment made by Robert Hauser on the topic of rapid smoking as a method of aversion therapy (see record 2005-09607-001). Lichtenstein points out the Hauser is correct in suggesting the need for screening before using rapid smoking or the closely related satiation and blown, smoky air procedures. Although Lichtenstein and his co-authors have not described or recommended screening procedures in their published works, he has done so in oral presentations. Hauser's comment serves as a useful correction to our omission of the need for a screening procedure. Lichtenstein points out, however, that Hauser has overstated the degree of risk involved in rapid smoking and is concerned with the tone of his comment. This tone may scare investigators away from a method that has shown promise and can be applied safely. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The study was a randomized placebo-controlled trial testing whether fluoxetine selectively enhances cessation for smokers with a history of depression. Euthymic smokers with (H+, n = 109) or without (H-, n = 138) a history of major depression received 60 mg fluoxetine or placebo plus group behavioral quit-smoking treatment for 12 weeks. Fluoxetine initially enhanced cessation for H+ smokers (p = .02) but subsequently impaired cessation regardless of depressive history. Six months after quit date, fluoxetine-treated participants were 3.3 times more likely to be smoking (p = .02). Further research is warranted to determine why high-dose fluoxetine produces continuing effects that oppose tobacco abstinence. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
