Analysis of the Extension Chain of Year-Round Production Technology of Potato Industry

Through the application of many measures such as the systematic conformity of three science and technology recourses, construction of technology chain with "five news linkage, six combined merits", the exploration of base demonstration mode with "three drives and three breakthroughs", the construction of cooperative mechanism with "six combination", etc. Long-term cooperative mechanism of close combination with Agricultural-Science-Education and Industry-University-Research Institution has been constructed by Sichuan potato innovation team. Meanwhile, a technology extensionmode with "innovation and transformation as a whole" has been constructed that relying on multi-function core demonstration base, with integrated demonstration of key technology as breakthrough, new advanced technology training as vector, integral advance of core demonstration county as emphasis, Industry-University-Research Institution combined together to build modern science-technology industrial chain of potato. Meanwhile, through the application of some methods such as optimize the regional distribution, extend virus-free seed potato, strength high-yield production, continuous radiating drive, and provide disaster response capacity to strengthen the cooperative mechanism and technology extension mode, then promote the potato area and total yield ranking at the first position in China.
