采用正交实验法在室温下合成了含有天然产物蒙脱土(MMT)和羧甲基纤维素钠(CMC)的系列环境友好型保水剂，研究了不同保水剂组成和合成条件对高羊茅品种可奇思(简称可奇思)种子发芽及生长指标的影响规律。结果表明，试验合成的保水剂能显著提高可奇思的发芽能力和植株的生长指标，天然组分 MMT 和 CMC 含量对其发芽和植株生长影响显著。用性能最佳的保水剂处理可奇思种子，其发芽率、发芽指数、活力指数、总干重、总根长和总分蘖数分别比空白对照试样提高了61.6%、80.5%、125%、102%、67.6%和68.6%，比市售合成类保水剂对照试样提高了4.50倍、5.50倍、7.60倍、6.88倍、3.88倍和3.92倍，这对提高可奇思种子发芽能力和促进其植株生长具有重要意义，对该保水剂在可奇思种子发芽中的应用提供了试验依据。
採用正交實驗法在室溫下閤成瞭含有天然產物矇脫土(MMT)和羧甲基纖維素鈉(CMC)的繫列環境友好型保水劑，研究瞭不同保水劑組成和閤成條件對高羊茅品種可奇思(簡稱可奇思)種子髮芽及生長指標的影響規律。結果錶明，試驗閤成的保水劑能顯著提高可奇思的髮芽能力和植株的生長指標，天然組分 MMT 和 CMC 含量對其髮芽和植株生長影響顯著。用性能最佳的保水劑處理可奇思種子，其髮芽率、髮芽指數、活力指數、總榦重、總根長和總分蘗數分彆比空白對照試樣提高瞭61.6%、80.5%、125%、102%、67.6%和68.6%，比市售閤成類保水劑對照試樣提高瞭4.50倍、5.50倍、7.60倍、6.88倍、3.88倍和3.92倍，這對提高可奇思種子髮芽能力和促進其植株生長具有重要意義，對該保水劑在可奇思種子髮芽中的應用提供瞭試驗依據。

Environmentally-friendly super-absorbent composites containing natural products such as mont-morillonite (MMT)and sodium carboxymethyl cellulose (CMC)were prepared at room temperature using or-thogonal experiment.The effects of natural products content and synthetic conditions on seed germination and growth capability of tall fescue Cochies were investigated.Rresults showed that the synthesized super-absorb-ents can significantly improved the seed germination and plant growth of Cochies.The orthogonal range analysis showed that MMT and CMC content have great influence on the seed germination and plant growth of Cochies. After treating the Cochies seeds with the optimum superabsorbent composites,their germination rate,germina-tion index,vigor index,total dry weight,total root length and total number of tillers were increased by 61.6%, 80.5%,125%,102%,67.6%,68.6%(compared to control)and by 4.5,5.5,7.6,6.88,3.88,3.92 times(com-pared to commercially available synthetic super-absorbents),respectively,which is practical to improve seed ger-mination capacity and growth of Cochies,providing an experimental basis for this super-absorbents in the appli-cation of Cochies.
