随着魔芋作为“保健食品”和“工业味精”的巨大工业价值潜力的不断挖掘和发现,魔芋产业迅猛发展起来,成为21世纪我国的一个朝阳产业,正日益成为山区农业增效、农民增收、企业增利、财政增税的支柱产业和出口创汇产业。山区农民种植魔芋的积极性高涨,魔芋种植面积逐年增加。随着魔芋种植面积的不断扩大和种植规模化,魔芋病害的发生也日益严重,正逐步成为制约魔芋产业向纵深发展的瓶颈因素。农民为了追求种植魔芋的高效益,同一田块连作种植魔芋的现象很普遍,由于生产配套技术的相对落后、病害防治技术的严重缺乏等因素的影响,魔芋连作田的病害发生率比非连作田平均高出35%～50%,造成减产达50%～80%,有的甚至绝收,严重挫伤了农民种植魔芋的积极性。要突破魔芋连作障碍,还是必须转到依靠科技种植和预防魔芋病害的轨道上来。
As konjac continues to be exploited and discovered as a huge industrial value potential of “health foods” and “industrial monosodium glutamate”, the konjac industry has developed rapidly and has become a sunrise industry in our country in the 21st century. It is increasingly becoming a major measure for increasing agricultural efficiency, Enterprises increase profits, the tax pillar of the tax industry and export industry. Mountain farmers planting konjac enthusiasm, konjac planting area increased year by year. With the continuous expansion of konjac planting area and planting scale, the occurrence of konjac disease is also increasingly serious, is gradually becoming the bottleneck restricting the development of konjac industry in depth. Farmers in pursuit of high efficiency of planting konjac, the same plots for planting konjac is common, due to the relative backward production technology, the lack of a serious disease control technology and other factors, the incidence of konjac plantation disease than non-cropland An average of 35% to 50% higher, resulting in reduced production of 50% to 80%, and some even absolutely unparalleled, seriously dampening the enthusiasm of farmers planting konjac. To break through the obstacle of konjac continuous cropping, or must rely on technology to plant and prevent konjac disease orbit.
