试验采用不同用量（１０、２０、３０、４０、５０ｇ／ｍ２）的ＴＱ－Ⅱ型吸水剂作为百慕达４１９坪床中改善土壤水分的重要原料，并使其浇水量限制为对照组２５％、５０％、７５％三个水平，结果表明：吸水剂用量为３０ｇ／ｍ２，浇水量为对照５０％的处理百慕达４１９株高、密度、盖度均表现好，且比对照有所提高，并与用泥炭作为保湿剂的处理差异不显著。当浇水量为对照的２５％时，吸水剂在５种用量下，百慕达４１９的长势都比较弱 TQ-Ⅱ water-absorbing agent with different dosage (10, 20, 30, 40 and 50g / m2) was used as the important raw material to improve soil moisture in 419-ping berm bed in Bermuda. %, 50% and 75% respectively. The results showed that the water-absorbing agent dosage was 30g / m2 and the watering amount was 50% The difference was not significant with the treatment of peat as humectant. When the watering amount is 25% of the control, the growth of Bermuda 419 is relatively weak under the 5 kinds of water-absorbing agents
