摘要

高爾夫球場之土壤規劃以砂地爲主，果嶺及球道都以鋪砂植草，砂地之保肥及保水力甚差，肥料易流失且保水力弱，平日噴水過多造成水量的浪費，太少又限制了草皮的生長，爲了維持草地的青翠，水分成爲草皮管理上除了肥料、農藥以外，另一項重要的管理技術。本研究中選用三種保水性強的高分子聚合物，其吸水倍數在蒸餾水中可達215〜340倍，但隨著溶液中離子濃度增加吸水能力降低。經由模擬管柱的實驗，聚合物對二價陽離子的吸附性強，對一價陽離子吸附較弱，且會釋出鈉離子；陰離子淋洗出的量較原來養液中的含量還高，顯示有部分聚合物內之陰離子釋出。高爾夫球場草地排水水樣分析，各水樣大多呈鹼性反應，pH介於7.0至9.4之間，EC值則介於54至970 μs/cm之間。

The most of golftands soil are sandy soil. The green and fairway are covered with sand before planting grass. The capacity of holding fertilizer and water is low in sandy soil, so fertilizer and water are easy to loss. In daily irrigation, too much water will waste water resource too little water will inhibit the growth of grass. In order to keep green and beautiful lawn, the water management is an important technique, besides fertilizer, herbcide, and pesticide. Three polymers selected in this study to hold water, they can absort water about 215~340 times of their dry weight in distilled water. However, the holding water capacity was decreased by increasing the salt concentration of solution. In the column experiment, the adsorptive capacity by polymers of divalent cations were stronger than that of monovalent, especially sodium ions. The anion contents of solution which leached in column were higher than the original nutrition solution, it showed that some anions were released by polymers. The pH of the most water samples from golf turf were high. Their electric conductivity (EC) values were between 54 and 970 μs/cm.
