【摘要】：為探究山砂是否可作高爾夫球場球道用砂,以達到降低高爾夫球場建造成本的目的,本研究采用長沙市普遍分布的山砂1號和山砂2號為研究材料,以河沙為對照,參照USGA球道用砂標準,通過對其物理與化學(xué)性狀測定及其作為高爾夫球場球道草坪建植基質(zhì)的應(yīng)用性狀綜合評價,獲得如下研究結(jié)果：1.物理性狀檢測結(jié)果表明：山砂1號和山砂2號的細度模數(shù)分別是3.2和3.1,屬于粗砂,山砂的粗顆粒含量較多,河沙的細度模數(shù)只有2.6,屬于中沙。受其顆粒特性的影響,兩種山砂的表觀密度與堆積密度都比河沙小。山砂的孔隙率比河沙高,但其含泥量比河沙要大,因此在30cm深度時,河沙滲透率比山砂稍高。USGA球道用砂標準要求滲透率15cm/h,孔隙度(35%-55%),三種沙的滲透率和孔隙度均符合標準。兩種山砂中0.25-1.0mm粒徑沙比重,山砂1號為35.6%,山砂2號為40.7%,難以達到占總量60%以上USGA球道用砂標準,可通過粉碎、過篩或水洗等處理,以達到USGA球道用砂標準。從整體的物理性狀對比來看,兩種山砂與河沙有差異,但影響不大。2.化學(xué)性狀檢測結(jié)果表明：山砂1、山砂2號和河沙的pH值分別為5.71、5.64和6.6,都處于多數(shù)草坪草種所適宜的微酸性-中性土壤pH值(5.5～7.0)的范圍之內(nèi)。山砂1、山砂2號和河沙的EC25值分別為1.03 mS/cm,1.1 mS/cm和0.56mS/cm,兩種山砂的EC值相差不大,但比河沙要大近一倍。山砂1、山砂2號和河沙的水溶性鹽分含量分別為0.04%、0.04%和0.01%,兩種山砂均比河沙高。當土壤水溶性鹽分含量0.2-0.3%,不會對草坪生長產(chǎn)生不利影響,兩種山砂與河沙的水溶性鹽分含量均未超標。因此,在化學(xué)性質(zhì)方面,兩種山砂都符合使用要求。3.以山砂1號、山砂2號和河沙作基質(zhì),參照USGA球道建造標準種植海浪海濱雀稗(尸aspalum vaginatum cv. Sea Spray),結(jié)果表明：在生育期方面,河沙基質(zhì)的海濱雀稗草坪成坪速度比山砂作基質(zhì)快,返青時間早,綠色期稍長,但對抽穗開花和結(jié)實沒有影響,兩種山砂在生育期的表現(xiàn)一致。在外部形態(tài)特征、生物量方面,三種基質(zhì)的海濱雀稗無顯著性差異。在坪用性狀方面,三種基質(zhì)的海濱雀稗草坪質(zhì)量評價均為優(yōu)秀,表明兩種山砂作高爾夫球道草坪基質(zhì)不會影響草坪質(zhì)量,其中山砂1號含泥量較低,更適合作高爾夫球道用砂。
[Abstract]:In order to explore whether mountain sand can be used as golf course fairway sand in order to reduce the construction cost of golf course, this study uses Shansha 1 and Shansha 2, which are widely distributed in Changsha City, as the research materials, and takes river sand as control. According to the standard of USGA fairway sand, the physical and chemical properties of the sand and the comprehensive evaluation of the characters used as the substrate for the establishment of golf course lawn were evaluated, and the following results were obtained: 1. The results of physical properties test show that the fineness modulus of Shansha 1 and Shansha 2 are 3.2 and 3.1 respectively, which belong to coarse sand, and the coarse grain content of mountain sand is more than that of river sand, and the fineness modulus of river sand is only 2.6, which belongs to middle sand. The apparent density and accumulation density of the two kinds of sand are smaller than that of the river sand. The porosity of mountain sand is higher than that of river sand, but its sediment content is higher than that of river sand. Therefore, at the depth of 30cm, the permeability of river sand is slightly higher than that of mountain sand. The sand standard of 30cm requires a permeability of 15 cm / h and porosity (35 -55%). The permeability and porosity of the three kinds of sand are all in line with the standard. The specific gravity of 0.25-1.0mm diameter sand in the two kinds of sand is 35.6 for Shan Sand No. 1 and 40.7for Shansha No. 2, which is difficult to reach the standard for USGA fairway sand which accounts for more than 60% of the total amount. The sand standard for USGA fairway can be reached by crushing, sifting or washing. From the comparison of the whole physical properties, the two kinds of mountain sand and river sand are different, but the effect is not significant. The results showed that the pH values of Shansha 1, Shansha 2 and river sand were 5.71 and 6.6, respectively, which were within the range of pH value (5.5N 7.0) of micro-acid neutral soil suitable for most turf grass species. The EC25 values of Shansha 1, Shansha 2 and river sand are 1.03 mS/cm,1.1 mS/cm and 0.56 Ms / cm, respectively. The EC values of the two kinds of sand are not different, but are nearly twice as large as that of river sand. The water soluble salt contents of Shansha 1, Shansha 2 and river sand are 0.04% and 0.01%, respectively. Both kinds of sand are higher than river sand. When the water-soluble salt content of the soil was 0.2-0.3, it would not adversely affect the growth of the lawn, and the water-soluble salt contents of the two kinds of sand and river sand were not above the standard. Therefore, in terms of chemical properties, the two kinds of mountain sand meet the requirements of use. 3. Using Shansha 1, Shansha 2 and River Sand as the substrate, and referring to the USGA fairway construction standard, the seashore paspalum (aspalum vaginatum cv.) was grown. The results of Sea Spray), showed that the turfgrass of seashore paspalum in river sand substrate was faster than that of sand as substrate, the green period was a little longer and the green period was a little longer, but it had no effect on heading, flowering and seed setting, and the two kinds of sand had the same performance in the growth period. There was no significant difference in the external morphological characteristics and biomass of seashore paspalum among the three substrates. In the field of turf characters, the quality evaluation of seashore paspalum grass with three kinds of substrates was excellent, which indicated that the two kinds of sand could not affect the lawn quality of golf course, and Zhongshan sand No. 1 had lower mud content, so it was more suitable for golf course sand.
