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 more serious diseases in the process of sugarcane planting, affecting the yield of cane and the quality of sucrose. In order to provide a reasonable planting mode for sugarcane fields with more serious outbreak of smut, we planted stems of sugarcane with smut of M. persicae before the beginning of the Lunar New Year and before the summer of 2012 to grow healthy sugarcane The stems were used as control to observe the incidence of smut and the effect on the effective stem, plant height, stem diameter and brix of sugarcane in the two growth stages. The results showed that under different climatic conditions, there was a significant difference in the incidence of smut from planting sugarcane with smut disease. Sugarcane with smut germ was suitable for early winter and early spring. Using the cold and damp weather in winter and spring, Germination of germs, reduce the effective stem infringement, thereby reducing the impact on yield.
