摘要
根据１９９１～１９９３年对潮土不同构型土壤的水分定位观测，比较了在同一气候下，不同构型土壤耕层的持水能力以及水分的利用特点．０～４０ｃｍ土层保墒能力：重壤＞上壤下粘＞砂壤土＞上粘下砂＞砂土；全年水分利用率：重壤＞上粘下砂＞砂土＞上壤下粘＞砂壤土。
On the basis of located trial data of soil water in different types of the soil body configuration(DTSBC) from 1991 to 1993, the water retention ability and water utilization characteristics were compared in arable layer of DTSBC under the similar climate conditions.
