To deal with the problem of air pollution, we must grasp three points: First, we must strengthen the ventilation system to prevent ammonia from staying in the greenhouse for too long. The second is to strengthen the management of fertilizers and water, and apply biological bacterial fertilizer or alginic acid with water to accelerate the maturation and decomposition of fertilizers in the soil. The third is to pay close attention to spraying alginic acid foliar fertilizer and alizarin lactone to promote the recovery and growth of the leaves.
