In recent years, many production units in the vegetable, flower plant nursery research, widely used solid material as a substrate instead of soil and culture medium for nursery, that is, soilless nursery method. Practice has proved that soilless seedling has many advantages over conventional seedling in soil. The seedling is neat and uniform, the seedling is fast and the strong seedling rate is high. After planting, seedling Huanmiao fast or not hibernating, Zhu Zhuang, and promote early maturity, high yield and so on. Can be seen that soilless seedling is a promising nursery method. At present, there are many kinds of substrates used in soilless seedlings, such as rock
