甘薯(山东省当地俗“地瓜”)脱毒是一项增产显著的高新技术,它是利用甘薯茎尖病毒含量低不带病毒的特性进行茎尖分生组织离体培养,获取试管苗后,再经病毒检测,将不带病毒的茎尖苗迅速隔离繁殖,用于生产。该技术是防止甘薯病毒病的有效途径。它有增产效果显著,抗病性明显提高,块膨大快等特点。一般比常规甘薯增产30％以上,每667m~2增鲜薯600kg以上,其栽培技术如下。
Sweet potato (Shandong local vulgar “sweet potatoes”) detoxification is a significant high yield technology, it is the use of sweet potato concoction virus content is low without virus characteristics of shoot apical meristem in vitro culture, after obtaining test tube seedlings, Then by virus detection, the virus-free stem spikelets quickly isolated breeding for the production. This technique is an effective way to prevent sweet potato virus disease. It has a significant effect of increasing yield, significantly improved disease resistance, rapid expansion of the block and so on. General than conventional sweet potato yield more than 30%, every 667m ~ 2 by more than 600kg of fresh potatoes, its cultivation techniques are as follows.
