摘要：为了研究并得到3种不同灌溉技术(滴灌、喷灌、漫灌)对冬小麦产量及其构成的影响,在中国农业大学吴桥实验站设计了滴灌、喷灌、漫灌的大田试验.3种灌溉技术条件下,其灌溉总量相同,漫灌和喷灌采用浇底墒水加浇两水,滴灌采用浇底墒水加浇四水的方式;从冬小麦整个生长期内的作物高度、叶面积指数、籽粒重等指标,考察不同灌溉技术对冬小麦生产及其构成的影响.结果表明:滴灌条件下,表层含水量下降速度最小,整个生长期,含水量高于喷灌和漫灌;滴灌处理的叶面积指数最高,其次是喷灌;在成熟期,滴灌条件下,作物高度比漫灌高12%,比喷灌高5%;滴灌和喷灌的条件下产量分别比漫灌高8.63%,7.75%;滴灌、喷灌、漫灌的籽粒千粒重分别为43.36,42.17和41.17 g,滴灌和喷灌籽粒重明显高于漫灌,且生物量分别比漫灌提高了6.9%,3%.这说明3种灌溉技术中,滴灌技术最有利于实现节水保墒、小麦增产,其次是喷灌.

摘要：One of the problems.that many engineering graduates.face when looking for their firs. job is. Do you have experience？ Employers.prefer graduates.with relevant experience to thos. without. Why is.experience s. important to employers. Can s.udents.accumulate ＂working＂ experience while s.udying in college？ This.paper dis.us.es.the us. of des.gn projects.ins.de and outs.de of clas.rooms.to help s.udents.gain ＂working＂ experience and s.ills.through hands.on des.gn activities.that s.mulate the actual des.gn activities.that occur in the indus.ry. Faculty members.from the Mechanical Engineering Technology and Computer Engineering Technology departments.were involved in creating multidis.iplinary des.gn projects. The des.gn projects.give s.udents.new ins.ghts.into what they learn in their cours.work and *** s.udents.the valuable experiences.in analytical s.ills. concurrent engineering approach, people s.ills. and management s.ills.needed for the s.udents.when looking for employment.
