Spraying foliar fertilizer after disaster can accelerate crop rehabilitation
July and August each year is a season in which typhoons and heavy rains occur in China and cause more serious damage. The disasters affect a wide area, crops, and large areas, resulting in serious losses. If foliar fertilizers are sprayed on the crops before and after the disaster, the ability of crops to resist disasters and prevent the invasion of pathogens can be improved, the recovery of affected crops can be accelerated, the vitality can be quickly restored, and the losses caused by disasters can be reduced. After the typhoon storm, the roots and aboveground parts of the affected crops will be damaged, the root activity and photosynthesis capacity will be affected, the ability to resist the infection of pathogens will be reduced, the crop root system will affect the absorption of soil nutrients, and the crop nutrient supply will be insufficient. Therefore, it must be timely. Supplement crops with effective nutrients so that crops can quickly return to life. After many years of practice, the most effective way to prevent and fight disasters is to apply foliar fertilizer to crops. Why spray foliar fertilizer can accelerate the rehabilitation of the crop after the disaster? This is mainly determined by the direct and rapid action characteristics of the foliar fertilizer. Foliar fertilizer can not only timely and effectively supplement the large and medium-sized elements and trace elements needed for crop growth, but more importantly, it can effectively regulate the metabolic balance in plants and make the crop grow robustly. Pre-disaster use can enhance the ability of crops to withstand disasters, improve the defense capability of crops against pathogens, and post-disaster spraying can enable affected crops to provide timely nutrition supplements, maintain metabolic balance, quickly recover, grow normally, and reduce losses caused by disasters.
