马铃薯易感染多种病毒而造成种薯退化,使产量大幅度下降,失去种用价值,严重影响了生产的发展。为解决这一难题,山东省农科院蔬菜所的科技人员经过多年研究,成功地利用组培技术快速微繁,结合血清学检测,对适合于山东省栽培的优良马铃薯品种,进行了脱毒小薯的工厂化大规模生产。5年来,已在省内外累计推广无毒种薯101.3万亩,比一般种薯平均每亩增产500～800公斤,累计纯增经济效益2.02亿元。充分显示了生物技术在农业生产中实际应用的诱人前景和产生的巨大经济效益。
Potatoes susceptible to a variety of viruses caused by the degradation of seed potatoes, so that a substantial decline in production, loss of species value, seriously affected the development of production. To solve this problem, Shandong Academy of Agricultural Sciences vegetable scientists after years of research, the successful use of tissue culture technology, rapid micro-propagation, combined with serological testing, suitable for cultivation of excellent varieties of Shandong Province, were detoxification Small potato factory mass production. Over the past five years, the total number of non-toxic seed potatoes has been increased to 1.031 million mu both inside and outside the province, an increase of 500-800 kilograms per mu compared with that of the average ones. The cumulative net economic benefits increased by 202 million yuan. It fully shows the attractive prospect of biotechnology application in agricultural production and the huge economic benefits.
