摘要
育苗割草和空心时间的曝气是破坏性的文化做法,改变土壤的物理性质。本研究的目的是评价刈割后空穴施肥对建立在“Tifway”杂交百米草(C. dactylon x C. transvaalensis Burtt)下的塞西尔砂壤土(壤土)和沙顶足球场(沙)土壤物理性质的影响。戴维)。连续两年在6月中旬进行0.25、0.5、1.0英寸三种刈割深度和空心时间曝气。测定了两种土壤的草坪草质量(TQ)、茅草垫深度、表面硬度和抗草皮侵蚀性。测定了砂土的饱和水力导率(Ksat)。在研究期间的2 - 6周内,所有的花苗刈割和中空时间曝气处理均导致TQ不可接受。然而,空穴曝气与育苗刈割相结合并没有延缓百慕大草的恢复。草席深度随刈割深度的增加而降低≥19%,但不受空期曝气影响。赞颂割草对Ksat没有影响;空心时间曝气使Ksat增加了54%。随着刈割深度的增加,表面硬度增加≤24%。育苗刈割对壤土抗草皮性无影响。0.5英寸和1.0英寸的刈割深度分别降低了16%和30%的沙土阻力。中空时间曝气使表面硬度降低5%至20%,抗剥落率降低6%至13%。当同时进行时,刈割和空穴施肥是互补的,并对两种土壤的物理性质产生积极影响。
Fraise mowing and hollow-tine aerification impact bermudagrass surfaces
Fraise mowing and hollow-tine aerification are disruptive cultural practices that alter soil physical properties. The objective of this study was to evaluate the effects of fraise mowing followed by hollow-tine aerification on soil physical properties in a Cecil sandy loam (loam) and a sand-capped soccer field (sand) beneath established ‘Tifway’ hybrid bermudagrass (C. dactylon x C. transvaalensis Burtt. Davy). Three fraise mowing depths (0.25, 0.5, and 1.0 inches) and hollow-tine aerification were applied in mid-June in two consecutive years. Turfgrass quality (TQ), thatch-mat depth, surface hardness, and divot resistance were measured in both soils. Saturated hydraulic conductivity (Ksat) was measured in the sand. All fraise mowing and hollow-tine aerification treatments resulted in unacceptable TQ for 2 to 6 weeks during the study. However, combining hollow-tine aerification with fraise mowing did not delay bermudagrass recovery. Thatch-mat depth decreased by ≥19% as fraise mowing depth increased but was unaffected by hollow-tine aerification. Fraise mowing did not affect Ksat; however, hollow-tine aerification increased Ksat by 54%. Surface hardness increased by ≤24% with increasing fraise mowing depths. Fraise mowing did not affect divot resistance in the loam. Divot resistance in sand decreased by 16 and 30% with the 0.5- and 1.0-inch fraise mowing depths, respectively. Hollow-tine aerification decreased surface hardness by 5% to 20% and divot resistance by 6% to 13%. When practiced concurrently, fraise mowing and hollow-tine aerification were complimentary and positively affected the soil physical properties in both soils.
期刊介绍:
Crop, Forage & Turfgrass Management is a peer-reviewed, international, electronic journal covering all aspects of applied crop, forage and grazinglands, and turfgrass management. The journal serves the professions related to the management of crops, forages and grazinglands, and turfgrass by publishing research, briefs, reviews, perspectives, and diagnostic and management guides that are beneficial to researchers, practitioners, educators, and industry representatives.
