甘薯“苗旺苗”是剪苗扞插繁殖薯苗的育苗方法,也有叫“藤旺藤”、“小娘藤”或“采苗圃”的。本省德清、余杭一带农民常用此法育苗。群众认为这一育苗方法有节约种薯、提高产量的好处;有些科研单位认为有减少黑斑病的作用。为了验证这些效果,以便在生产上扩大利用,我们对这种育苗方式作了一些观察,并进行了一些简单的试验。现在把观察和试验的初步结果,作一报导。通过试验,证明“苗旺苗”具有下列几方面的优 Sweet potato “Miao Wang Miao” is cut seedlings to defend the propagation of potato seedling breeding methods, but also called “vine Wang vine”, “Little Lady” or “mining nursery.” Deqing, Yuhang area farmers commonly used this method nursery. The masses believe that this method of seedling conservation of seed, increase the benefits of yield; some research institutes that have the role of reducing black spot. In order to validate these effects in order to expand their use in production, we made some observations on this breeding method and conducted some simple experiments. Let us now report the preliminary results of the observation and experiment. Through experiments, that “Miao Wang Miao” has the following advantages
