摘要

1997年夏天，在伊利诺伊州格伦维尤的北岸乡村俱乐部建造了一个短游戏练习设施。除了作为一个功能实践区，该设计还包括各种研究目标，包括在7200平方英尺的果岭中对几个根区进行实地测试。所有根区都用相同的沙子建造，在粒度和分布上符合USGA规范，并按照USGA剖面标准建造。在14 ' × 15 '和12 '深的细胞中使用了20种不同的根区混合物。从豌豆砾石床的顶部延伸到表面的永久80毫米高密度聚乙烯屏障将细胞分开。所有地块均采用L-93和SR-1119的50/50混合种子，每1000平方英尺2磅。种毯用于帮助生长和防止任何潜在的侵蚀，直到幼苗建立。所有的地块都被平等地管理，并在草皮成熟时用直沙覆盖。根区细胞包括:直砂;85/15泥炭;90/10 Dakota Peat;90/10 Dakota Peat + Chip Humate (250#);90/10 Dakota Peat加22.5% Profile(多孔陶瓷);90/10达科他泥炭加15% (v/v)剖面和350磅ZeoPro (zeoponic沸石);90/10达科他泥炭加10% Zeopro (v/v);90/10达科他泥炭加10% Axis(煅烧硅藻土);90/10 Dakota Peat加上10% Axis和350磅Zeopro;90/10达科他泥炭加100磅OptiMil(粒状海洋植物粉和蜜organite与葵花籽壳灰，总N-P-K为3-1-4);90/10达科他泥炭加100磅OptiMil和翡翠岛微生物哈茨木霉和内生菌根真菌;90/10达科他泥炭加60磅SAND_AID(颗粒状海洋植物粉，1-0-1);90/10达科他泥炭加60磅sandaid和翡翠岛微生物哈茨木霉和内生菌根真菌;90/10达科他泥炭加上300磅顺磁玄武岩，40磅硬岩磷酸盐和40磅格林桑;90/10 Yardwaste堆肥;90/10有机固体残;90/5/5 yardwaste /有机固体残;沙子混合10斤Hydrozone(吸水聚丙烯酰胺共聚物);砂混合5磅的Hydrozone和蚯蚓铸件;本地泥炭占90%。结果将被展示和讨论。

A Field Trial Comparing 20 Different Rootzone Mixes of Various Organic and Inorganic Amendments

A short game practice facility was constructed at North Shore Country Club, Glenview Illinois in the summer of 1997. In addition to it being a functional practice area, the design included various research objectives including field-testing several rootzone amendments in the 7,200 square feet putting green. All rootzones were constructed with the same sand, meeting USGA specifications in particle size and distribution and built to a USGA profile standard. 20 different rootzone mixes were used in cells measuring 14’ × 15’ and 12” deep. A permanent 80-mil high-density polyethylene barrier extending from the top of the pea gravel bed to the surface divided the cells. All plots were seeded with a 50/50 blend of L-93 and SR-1119 at 2 lbs/1,000 ft².

A seed blanket was used to assist grow-in and protect from any potential erosion until seedling establishment. All plots were managed equally and topdressed with straight sand as the turf matured. Rootzone cells consisted of: Straight Sand; 85/15 Sphagnum Peat; 90/10 Dakota Peat; 90/10 Dakota Peat plus Chip Humate (250#); 90/10 Dakota Peat plus 22.5% Profile (porous ceramic); 90/10 Dakota Peat plus 15% (v/v) Profile and 350 pounds ZeoPro (zeoponic zeolite); 90/10 Dakota Peat plus 10% (v/v) Zeopro; 90/10 Dakota Peat plus 10% Axis (calcined diatomaceous earth); 90/10 Dakota Peat plus 10% Axis and 350 pounds Zeopro; 90/10 Dakota Peat plus 100 pounds OptiMil (granular Sea Plant Meal and Milorganite with sunflower seed hull ash, total N-P-K of 3-1-4); 90/10 Dakota Peat plus 100 pounds OptiMil and Emerald Isle Microbial Trichoderma harzianum and endomycorrhizal fungi; 90/10 Dakota Peat plus 60 pounds SAND_AID (granular Sea Plant Meal, 1-0-1); 90/10 Dakota Peat plus 60 pounds SAND-AID and Emerald Isle Microbial Trichoderma harzianum and endomycorrhizal fungi; 90/10 Dakota Peat plus 300 pounds Paramagnetic basalt rock, 40 pounds Hard Rock Phosphate and 40 pounds Greensand; 90/10 Yardwaste Compost; 90/10 Biosolids; 90/5/5 yardwaste/biosolids; Sand mixed with 10 pounds Hydrozone (water absorbing polyacrylamide copolymer); Sand mixed with 5 pounds Hydrozone and earthworm castings; and 90/10 local peat. The results will be presented and discussed.
