云南省具有发展魔芋产业自勺自然条件,但魔芋本身是喜阴植物,规模化种植历史还较短,相关研究资料还很少,可借鉴的应用技术更是少之又少。大面积规模化种植后,导致病原菌优势生理小种加速发展,主栽品种的抗病能力日趋减弱,病害流行周期越来越短,发生频繁,造成减产甚至绝收。加之,魔芋繁殖系数低,种芋价格高,用种量大,首期投入成本高,种植过程 Yunnan Province has the natural conditions for the development of konjac industry spoon, but konjac itself is a shade-yin plant, the scale of planting is still short history, the relevant research data is still small, can learn from the application of technology is very small. Large-scale large-scale planting, leading to the accelerated development of the dominant race of pathogenic bacteria, the main cultivars increasingly weakened disease resistance, disease epidemic cycle shorter and shorter, frequent occurrence, resulting in reduced production or even absolute. In addition, konjac breeding coefficient is low, the high price of species of taro, with a large amount of investment, the first phase of high cost, planting process
