By focusing on the coupling of water and fertilizer and using all-purpose regression design with four factors and five levels, and based on pot experiments and quantitative analysis, the coupling effect of water and fertilizer on Casuarina equsetifolia biomass was studied in order to solve the inconsistency problem of water and fertilizer supply on coastal sandy land.

针对滨海沙地因水肥不协调而形成大面积低效林分的问题，以水肥耦合为中心，以1年生木麻黄幼苗为研究对象，采用四因子五水平二次通用旋转组合设计，利用盆栽试验和定量分析的方法，研究探讨了在不同水肥条件下，水、N、P、K四因子对木麻黄生物量的影响。

Under the direct current electric field, the expression of PDGFR were increased obviously and distributed asymmetricly on the membrane of VSMC. This receptor were mainly focused on the cathodal side of cellular membrane in electric field. The AT1R were also enhanced in the cells after exposure to the electric field, and the expression of AT2R had showed the changeless.
