摘要
甘蔗黑穗病是甘蔗种植过程中危害较为严重的病害之一,影响甘蔗的蔗茎产量和蔗糖分质量。为对黑穗病爆发比较严重的蔗区提供一种合理的种植模式,分别在2012年农历立春前及立夏前种植带黑穗病菌的甘蔗种茎,以种植未感染黑穗病菌的健康甘蔗种茎作为对照,观察这2期甘蔗生长过程的黑穗病发病情况,以及对甘蔗有效茎、株高、茎径和锤度的影响。结果表明:在不同的气候环境下,种植携带黑穗病菌的蔗种黑穗病发病差异显著;携带黑穗病菌的蔗种宜冬春早种,利用冬春季节阴冷潮湿的天气,延迟黑穗病菌的萌发,减少对有效茎的侵害,进而减少对产量的影响。
Sugarcane smut is one of the most serious diseases in sugarcane production.It will seriously affect the cane yield.In the study,sugarcane seedcanes carrying smut pathogen were planted while healthy seedcanes were used as the control in spring and summer in 2012.Smut disease,effective stalks,height,diameter and brix were checked.It was revealed seedcanes carrying smut pathogen would lead to severe disease,and the seedcanes carrying smut pathogen should be planted in spring and winter to delay the occurance the disease and further alleviate loss.
