本研究通过育苗方式比较试验、基质筛选试验、育苗专用肥配方试验、剪叶试验、移栽深度试验表明 ,漂浮苗具有更发达的根系 ,更大的根冠比 ,并且更容易达到培育高茎壮苗的目标。烟草大棚漂浮烟苗有利于实现育苗技术的规范化和成苗质量的标准化 ,与传统的育苗相比 ,漂浮育苗技术含量更高 ,降低了土传病害的几率 ,完全根系移栽和剪叶炼苗措施 ,能促使烟苗早发快长 ,增强早期的抗逆能力 ,防止大田早期低温可能诱发的早花 ,集约化的管理方式 ,极大地提高了育苗效率 ,可以实现烟草育苗的专业化和商品化
In this study, the comparative experiments of seedling mode, matrix screening test, formula test of seedling special fertilizer, leaf cutting test, depth of transplanting test showed that the floating seedlings had more developed root system, larger root-crown ratio and easier to cultivate high stem Strong seedling goal. Tobacco greenhouse floating tobacco seedlings is conducive to the standardization of seedling technology and the standardization of seedling quality, compared with the traditional nursery, floating nursery higher technical content, reducing the risk of soil-borne diseases, complete root transplanting and leaf scrubbing Measures can promote the rapid growth of tobacco seedlings earlier, enhance the early resilience and prevent early low temperature in the field may induce early flowering, intensive management, which greatly improved the efficiency of nursery, nursery tobacco can achieve the specialization and commodity The
