摘　　要：利用新育成的大穗型籼二系杂交稻组合光优５８进行了高产栽培示范试验，获得了１０５３０ｋｇ／ｈｍ２的高产，比汕优６３增产７．８％。并总结出“前促中控后重”的大穗高产栽培策略和培育多蘖壮秧、增蔸增苗，重视后期管理，以壮秧保大穗，以增蔸增苗来增穗，以加强后期管理来提高结实率和粒重的大穗高产栽培技术。The high yield cultural experiment on 'Guangyou 58', It is a large ear line of two line system hydrid rice of indica, was made. In the study, the kernel yield of 10 530 kg/hm 2 was obtained and was more 7.8% than yield of 'Xianyou 63'. A cultural strategy on 'Guangyou 58' that the seedling growth should was promoted in initial stage, was controled in middle stage, strengthened productive manage had brought forward to got more number of tiller seedlings, and more number of plants and ears in unit area, more larger setting percentage and a more weight of kernel.
