The floating seedling raising can strictly control the environmental conditions of the plants in the seedling stage, and greatly reduces the incidence of diseases. Secondly, the environmental conditions are effectively controlled, and the seedling raising time is shortened while strong seedlings are cultivated. The floating seedling raising is carried out in a plastic greenhouse, which is beneficial to artificially monitoring and regulating the conditions unfavorable for the growth of the seedlings and regulating the growth and development conditions such as temperature, humidity and the like of plants in the greenhouse, thereby enabling the seedlings to grow neatly, the root systems to be developed and the seedlings to grow robustly. The method can effectively control the long low-temperature time, large day and night temperature difference, slow seedling growth and the like in the seedling raising period, and save the seedling raising time. Thirdly, the root system is developed, and the field adaptability is strong. The plant that floats grow seedlings has a large amount of root hairs, and every plant mutual independence, can easily pull out the seedling together with the matrix from the cave hole during the transplantation, in transplanting to the field, has improved field transplanting efficiency, and root system root hairs do not receive the damage when seedling transplanting in addition, and the absorption nutrient and the moisture that can be quick after transplanting to the field can hardly receive the influence so the seedling grows after the field planting. Fourthly, the operation and management of floating seedling raising are convenient, and great effect is achieved on reducing the cost of seedling raising. With the addition of the matched equipment such as the seeder, the seed consumption and the investment of labor force are reduced, and the seedling raising cost is reduced.
However, in the floating seedling raising, the problems that the seedlings are not regularly raised, the substrate is salted, the surfaces of the seedling raising plates are provided with moss, the floating seedling raising plates need to be taken out from a water pool before transplanting, the floating seedling raising plates are placed in a wide and ventilated place for seedling hardening and the like exist.
