In the tobacco floating seedling process, fertilization is an extremely important link. Scientific and accurate fertilization is the key of successful fertilization, and the fertilization is inaccurate, so that partial tobacco seedlings are not long after being fertilized, and the phenomenon of partial tobacco seedlings burning is caused too much. Meanwhile, according to the suitability of the field transplanting conditions, the seedling forming progress of the tobacco seedlings can be regulated and controlled by accurate fertilization.
However, excessive fertilization or excessive concentration of local nutrient solution caused by adopting a skylight-opening mode when adding fertilizer for the second time often occurs in the existing tobacco floating seedling raising process, and the occurrence of tobacco seedling fertilizer damage, tobacco seedling root necrosis, yellowing of leaves and even death of the leaves are easily caused. In addition, in recent years, when partial areas are required to grow seedlings, the depth of pool water is shallow, for example, about 5cm, so that the temperature is favorably raised, but the occurrence probability of fertilizer damage is increased. If the air temperature is high, the evaporation capacity of the nutrient solution is large or the height of the pool is uneven, so that the concentration of the nutrient solution is easy to rise or the local concentration is high, and fertilizer damage is caused.
