In the frame of the Sino-Italian Cooperation Program for Environmental Protection, jointly launched in the year 2000 by the Italian Ministry for Environment and Territory and Sea (IMETS) and the China State Environmental Protection Administration (SEPA), experimental trials were carried out in Qingzhou city (Shandong Province, China) during 2001-2003 to test several methyl bromide alternative methods to control soilborne diseases in greenhouse tomatoes. Grafting tomatoes on resistant rootstock (Lycopersicon lycopersicum × L. hirsutum), metham sodium applied under traditional polyethylene plastic films, metham sodium applied at low rate under virtually impermeable films and soil solarization combined with biocontrol agents were the alternatives tested and compared to methyl bromide applied under virtually impermeable plastic films too. Collected data show that resistant rootstock (Lycopersicon lycopersicum × L. hirsutum) introduced from Italy is a promising alternative to methyl bromide for local tomato cultivars. Metham sodium applied under traditional polyethylene plastic films is an effective alternative. Moreover, virtually impermeable films demonstrate the help to reduce methyl bromide and metham sodium rates. Finally, soil solarization combined with biocontrol agents does not provide satisfactory results in terms of disease control.

摘 要:课堂气氛是指课堂教学过程中所表现出来的公共情绪状态,它是课堂教学能否顺利进行的一个重要因素。那么,如何创造良好的小学语文教学气氛呢? 本文针对这一问题谈了几点看法。  关键词:语文教学;气氛效果;主导作用  课堂气氛是指课堂教学过程中所表现出来的公共情绪状态,它是课堂教学能否顺利进行的一个重要因素。良好的数学课堂气氛,对于提高学生学习语文的兴趣,开发智力,陶冶情操,优化教学效果等都具有十分
摘 要:学生是祖国的未来,是我国未来存亡兴衰的关键,肩负着建设祖国的重大使命。因此,在对学生进行教育的过程中,教师不仅仅要培养学生的基础知识理论,还应该重视学生思维能力的培养,通过多样化的教学模式激发学生的学习兴趣,促进学生个性化的发展。因此,在初中数学教学过程中,教师应该采取互动教学模式,从而激发学生对于数学的学习兴趣,高效的完成教学效率。  关键词:初中数学;互动教学;教学模式;兴趣爱好  一
