近几年来我省大面积推广脱毒地瓜,取得了很大成绩,对提高产量、改善品质、增加效益已成共识。科技兴农,种子先行,人所皆知。推广脱毒地瓜已列入山东省的种子工程。这是推动农业“二高一优”的重要举措。让高新技术在促进农业生产中发挥应有作用。现仅就有关推广脱毒地瓜的技术问题加以介绍。一、为什么要脱毒病毒是比细菌还小的生命体。它不具细胞结构,是在活体的细胞内寄生、繁殖、扩展、蔓延。凡无性繁殖植物一旦被病毒侵染后,便世代相传,从而致使产量降低,品质变劣、地力消耗增 In recent years, a large area in our province to promote detoxification sweet potatoes, made great achievements, to increase production, improve quality and increase efficiency has become a consensus. Science and technology agriculture, the seeds of the first, we all know. Promote detoxification sweet potatoes have been included in the Shandong province seed project. This is an important measure to promote agriculture, “two high and one excellent.” Let high and new technologies play their due role in promoting agricultural production. The technical issues related to the promotion of detoxification sweet potatoes are now covered. First, why virus-free virus is a smaller body than bacteria. It does not have cellular structure, is parasitic in the living cells, reproduction, expansion, spread. Where the vegetative propagation of plants once infected by the virus, then handed down from generation to generation, resulting in lower yield, poor quality, increased ground power consumption
