研究结果表明，超高产玉米田土壤物理肥力特性较高，主要表现在耕层较深厚，土壤容重变化在1.01～1.26g/cm3，土壤的结构破坏率较低；在土壤的化学环境特征方面，土壤碱解氮、速效磷、速效钾等均未表现出明显的变化规律；所有超高产田的土壤阳离子交换量均不同程度地高于普通生产田，这与超高产田的定向培育有直接关系；一些超高产田有机质低于普通生产田，其原因与超高产田氮素施用量较高、促进了土壤有机质矿化有关。

The bulky ortho-brominated aryl groups are implanted to create nonplanarity around amino center. Thus, the effective conjugation length to the protonation site is shortened and the energy gap between neutral and protonated forms is narrowed. The protonation can only occur at the nitrogen atom of the benzothiazole and the temperature variation disturbs the equilibrium between the neutral and monocation and the reverible thermochromic effect can thus be achieved.
