The drying of the upper soil layer in bare ground is progressing very fast, but that of the deeper layers is difficult. Furthermore, since the coefficient of water permeability of muddy soil after initial reclamation is as low as 10^<-5>-10^<-7>cm/sec and the greater part of soil water is absorbed on the soil particles, it is difficult to move soil water by means of gravity. Introduction of P. communis to polder may be an effective means of desiccating muddy soil, because active transpiration of P. communis plants can reduce soil water in the lower layers of the ground.P. communis can liberate a large amount of gas especially from the base of the culm into the surface water even under normal pressure in the afternoon in the summer season.

裸地表层土壤的干燥进展很快，但深层土壤的干燥却很困难。此外，由于初次复垦后泥质土的透水系数低至10^<-5>-10^<-7>cm/sec，且大部分土壤水被土壤颗粒吸收，因此难以通过重力移动土壤水。在圩田引入白杨可能是使泥质土壤干燥的有效手段，因为白杨植物的活跃蒸腾作用可以减少地表下层的土壤水分。即使在夏季下午常压下，玉米草也会释放大量气体，特别是从茎基部释放到地表水中。
