The use of less volatile or less volatile fertilizers to protect the ground within a relatively small amount of ventilation, which is easy to accumulate harmful gases, the occurrence of harmful gas poisoning phenomenon, it is not appropriate to use volatile fertilizer for ground flushing. Fertilizer fertilization should be suitable for fertilization with a large amount of water, and fertilization is highly diluted. If the amount of fertilization is insufficient and the concentration of the fertilizer solution is too low, the effect of fertilizer is poor, and the effect due to the application of fertilizer will not be achieved. If the amount of fertilizer is too large, or the amount of water applied during fertilization is insufficient, the concentration of the fertilizer solution is too high and rooting is prone to occur. For volatile fertilizers, when the concentration of fertilizer solution is too high, the amount of harmful gases that volatilize into the air is relatively increased, and the chance of harmful gas poisoning also increases. To reduce the residual amount of ground-fertilizer in the low-temperature period, try to use some chemical fertilizers with good water-solubility to flush them. When organic fertilizers are used for flushing, the supernatant of the mash shall be used for fertilization. When flushing with some easily volatile fertilizers, appropriate amounts of water should be applied again after fertilization to further dilute the fertilizer on the ground. Watering volume should be suitable for flushing and fertilizing. Flooding should not be flooded to avoid or reduce the loss of nutrients in fertilizers. However, it is also not possible to use too little water, to prevent fertilizers from excessively high concentrations of fertilizers, and to cause surface salinization after long-term high-level fertilization. The specific amount of watering should be determined according to the soil type and the cultivation period of the vegetables.
