简介:明椒5号系三明市农科所自主研发的适宜酱制、干制的加工专用型杂交一代辣椒新品种,具有早熟性好、产量高、辣味强、香味浓郁等特点,其辣度、香味及含水量等指标,符合辣椒加工企业的要求。该品种于2011年3月通过福建省农作物品种评定委员会评定。为提高明椒5号辣椒制种的产量和纯度,根据当地多年的辣椒种子生产实践,其制种技术推广尤为关键。1播种期辣椒制种栽培其播种期的确定应以种株授粉受精时期处于环境条件最适期,并确保种子能最后成熟和获得最高种子产量为原则。明椒5号辣椒种子从授粉到成熟需要60-70d,因此,各制种地应根据当地适宜气候条件安排播种适期,其中海南制种最佳播种期为8月底至9月初;华北、西北地区最佳播种期为3月底至4月初。
