1976—1977年在雷丁大学农场进行了两次蚕豆灌溉试验。设计的三种灌溉处理是湿,中湿,干。品种为Maris Bead,随机区组排列,四次重复。各小区都用蒙有透明聚乙烯薄膜的框架复盖。复盖区外另设置第4处理区,以便与开放条件下的作物生长进行比较。 1976年播种时各区给予相同灌溉量,便于整齐出苗和确立共同的起始点。1977年播种时因雨在出苗前未复盖。两年灌溉处理为整个生长期定期喷灌,以使最旺盛生长的叶(植株顶 Two faba bean farms were conducted at the University of Reading in 1976-1977. Three kinds of irrigation design is wet, wet, dry. Variety Maris Bead, randomized block arrangement, four repetitions. Each cell is covered with a transparent polyethylene film frame. A fourth treatment area is provided outside the covered area for comparison with crop growth under open conditions. The same amount of irrigation was given to each district in 1976 when sowing, to facilitate neat emergence and establishment of a common starting point. Seeds were not covered before emergence due to rain in 1977. Two-year irrigation treatment for the entire growing season of regular irrigation, so that the most prosperous growth of the leaves (plant top
