“早衰”是高粱生产和育种上存在的普遍现象。长期以来被认为是一种生理性病害。经4年研究证明它是草酸青霉(Penicilliem axalicum)和纤细交链孢霉(Allernaria allernala)于初花期浸染而引起的一种高粱穗部病害。主要症状是颖壳及与其连接的枝梗组织坏死,阻止了养分、水分向上输导,造成籽粒秕瘦变小。一般减产10％以上。这是国内首次报道的高粱新病害,定名为高粱青霉颖枯病,此病在初花期用多菌灵防治有较好效果。
Premature aging is a common phenomenon in sorghum production and breeding. Has long been considered a physiological disease. After 4 years of research it is proved that it is a sorghum ear disease caused by infiltration of Penicilliem axalicum and Allernaria allernala at the first flowering stage. The main symptom is the necrosis of the glume and the branches and stems connected with it, which prevent the nutrients and water from being transported upwards, resulting in the thinning and thinning of the grains. General reduction of more than 10%. This is the first report of a new sorghum disease in China, named as Penicillium sorbifolia, the disease early prevention and treatment of carbendazim have a better effect.
