Mechanism of action: Iron chlorin is a new type of plant growth regulator that contains a variety of plant active substances, which can activate multiple activities of plants and promote plant growth and development. Bihu is a purely natural high-tech biological product that contains more than 30 plant active substances such as natural plant endogenous hormones, flavonoids and amino acids, forming a unique "plant growth compound balance regulation system". The entire process from crop seed germination to flowering, fruiting, and maturation plays a comprehensive balancing role. Therefore, the mechanism of action of iron chlorin is more unique and comprehensive.
2. Efficacy: Iron chlorin has a variety of effects, including promoting root growth, improving fertilizer utilization, enhancing plant stress resistance, and improving the quality of agricultural products. Bihu has the effects of promoting seed germination, increasing seedling emergence rate, promoting seedling growth, increasing yield and improving quality. Although the effects of Bihu and Iron Chlorin are somewhat similar, the effects of Iron Chlorin are more extensive and comprehensive. Therefore, iron chlorin is better.
