脱毒马铃薯是指带病毒的马铃薯经茎尖培养、微繁、扩繁而获得的一种不带病毒的种薯。目前适合于华东、华北及黄淮流域推广种植的脱毒马铃薯品种鲁引1号、津引8号和荷薯5号,一般亩产2500公斤左右、高产可达3500公斤。一、脱毒马铃薯的特点:脱毒马铃薯由于不带病毒,生长势强,与脱毒前相比,株高增加25%,叶面积增加37%,叶片光合能力增加41.9%,植株抗高温和干旱能力也显著增强。产量和商品性能也明显提高,据菏泽地区高新农业科研所和山东农科院先后在苏、鲁、豫、皖等十余个省地大面积试验,脱毒薯可比未脱毒薯增产50-100%,甚至更多。但脱毒薯在
Virus-free potato refers to a virus-free seed potato obtained by culturing the shoot tips, micropropagation and propagation. Currently suitable for the promotion of planting in East China, North China and the Huang-Huai Valley detoxification potato varieties Lu cited No. 1, No. Jin cited No. 8 and No. 5 Sweet Potato, generally about 2,500 kilograms per mu yield of up to 3,500 kilograms. First, the characteristics of virus-free potato: virus-free due to no virus, strong growth potential, compared with before detoxification, plant height increased by 25%, leaf area increased 37%, leaf photosynthetic capacity increased 41.9% Drought capacity is also significantly enhanced. Yield and product performance has also significantly improved, according to high-tech agricultural research institutes in Heze and Shandong Academy of Agricultural Sciences in the Soviet Union, Shandong, Henan and Anhui provinces more than 10 large-scale test, 100% or more.
