聚乙二醇 (P.E.G.) 6000 和 P.E.G. 的评价以压力膜为标准，对土壤水基质势进行了20000次渗透控制。结果表明，三种方法在-0.51 和-15.3 个大气压之间的四种基质势下没有统计学上的显着差异。因此，无论是 P.E.G. 6000 或 P.E.G. 20,000可令人满意地用于土壤水基质势的渗透控制。
An evaluation of polyethylene glycol (P.E.G.) 6000 and P.E.G. 20,000 in the osmotic control of soil water matric potential was conducted using the pressure membrane as a standard. Results indicated that there were no statistically significant differences between the three methods at four matric potentials between −0.51 and −15.3 atmospheres. Hence, either P.E.G. 6000 or P.E.G. 20,000 can be used satisfactorily in the osmotic control of soil water matric potential.
