Breeding and high yield cultural techniques of new barley variety E Damai No 6

鄂大麦６号是以来自日本的皮穗波作母本，秀８０１７为父本杂交，经系谱法选育而成的二棱啤酒大麦新品种。株高８０～８５ｃｍ，千粒重４５ｇ，迟播早熟，全生育期１７５ｄ；品质达国标一级啤麦标准；省区试及省内外试种示范一般公顷产量在４５００ｋｇ以上，高产可达６０００ｋｇ以上。其栽培主攻方向是增穗数兼顾增粒重。因此，栽培上宜采取早播育壮苗，以肥力定密度的措施，即１０月下旬至１１月初播种，力争壮苗早发；每公顷基本苗上等肥力和早茬口田１９５万，中等肥力田２２５万，三等地力或晚茬口田３００万。同时注意科学施肥和防病治草。
