近20年来生物技术在植物育种上和快繁上应用发展很快,受到国内外广泛重视,如美国、新加坡、泰国以及日本等,利用这一技术,进行工厂化生产花卉、瓜果、蔬菜等,经济效益显著.近年我国在这方面的研究与应用也有较大的发展,但工厂化生产试管苗,尚未广泛应用,其主要原因是成本较高,以及在多次转移培养中,易导致大量污染、影响成苗 In recent 20 years, biotechnology has been applied rapidly in plant breeding and rapid propagation. It has been widely regarded at home and abroad, such as the United States, Singapore, Thailand and Japan, and utilized this technology to plant flowers, fruits, vegetables, etc. , Significant economic benefits.In recent years, China’s research and application in this area also have greater development, but the factory production of test tube seedlings, not widely used, the main reason is the high cost, and in a number of transfer culture, easily lead to a large number Pollution, affecting seedlings
