摘要

摘要甲巯唑啉通常用于安全、选择性地去除蔓生弯草高尔夫球场草坪上的一年生蓝草。在2013年和2014年进行了研究，目的是评估由合成肥料和生物刺激剂组成的生育计划，有和没有植物生长调节剂trinexapac-ethyl，以帮助在每年通过甲巯唑啉去除蓝草后恢复绿色树冠。进一步的研究进行了比较匍匐曲草的恢复后，积极的核心曝气事件与生育计划有和没有甲巯唑啉。在所有情况下，每两周一次从肥料或生物刺激剂中添加7公斤每公顷的N-P-K，使草坪草的恢复时间比单独使用标准草坪的生育计划增加了1至3周。在所有情况下，使用生物刺激剂处理的匍匐弯曲草的恢复与使用合成肥料(SF)处理的匍匐弯曲草相当或更快。在甲巯唑啉处理下，trinexapac-ethyl在两个位置将T90回收率降低0.25 ~ 0.5周，在一个位置将T90回收率提高0.1周。另外，用顺丰加trinexapac-ethyl处理的地块与只用顺丰处理的地块相当。甲巯唑啉在发生严重干旱胁迫的一个地点减缓了草坪草的恢复时间，而在没有经历干旱胁迫的另一个地点则没有。这些结果表明，草坪管理者应增加肥料处理，但不需要停止使用trinexapac-ethyl，以便在每年用甲巯唑啉控制蓝草后最大限度地恢复匍匐的曲草。这些数据还表明，当经历干旱胁迫时，甲巯唑啉有可能对匍匐弯草的恢复产生负面影响。术语:Methiozolin;trinexapac-ethyl;年度蓝草;[a];爬bentgrass;匍匐茎

Effect of core cultivation, fertility, and plant growth regulators on recovery of voided creeping bentgrass greens canopies following annual bluegrass control via methiozolin

Abstract Methiozolin is commonly used for the safe and selective removal of annual bluegrass from creeping bentgrass golf greens. Studies were conducted in 2013 and 2014 with the objective of assessing fertility programs consisting of synthetic fertilizers and biostimulants, with and without the plant growth regulator trinexapac-ethyl, to aid putting green canopy recovery following annual bluegrass removal via methiozolin. Additional studies were conducted to compare recovery of creeping bentgrass following an aggressive core aerification event with fertility programs with and without methiozolin. In all cases, the addition of 7 kg ha–1 of N-P-K from fertilizer or biostimulant biweekly to greens increased turfgrass recovery time by 1 to 3 wk compared to a standard green's fertility program alone. Creeping bentgrass treated with biostimulants recovered equivalent to or quicker than creeping bentgrass treated with synthetic fertilizer (SF) in all cases. In the presence of methiozolin treatments, trinexapac-ethyl reduced time to 90% recovery (T90) by 0.25 to 0.5 wk at two locations, and increased T90 recovery time by 0.1 wk at one location. Otherwise, plots treated with SF plus trinexapac-ethyl were equivalent to plots treated with SF only. Methiozolin slowed turfgrass recovery time at one location where severe drought stress occurred but not at the other location that did not experience drought stress. These results suggest that turf managers should increase fertilizer treatments but will not need to discontinue trinexapac-ethyl use to maximize creeping bentgrass recovery following annual bluegrass control with methiozolin. These data also suggest that methiozolin has the potential to negatively affect creeping bentgrass recovery when drought stress is experienced.

期刊介绍： Weed Technology publishes original research and scholarship in the form of peer-reviewed articles focused on understanding how weeds are managed. The journal focuses on: - Applied aspects concerning the management of weeds in agricultural systems - Herbicides used to manage undesired vegetation, weed biology and control - Weed/crop management systems - Reports of new weed problems -New technologies for weed management and special articles emphasizing technology transfer to improve weed control -Articles dealing with plant growth regulators and management of undesired plant growth may also be accepted, provided there is clear relevance to weed science technology, e.g., turfgrass or woody plant management along rights-of-way, vegetation management in forest, aquatic, or other non-crop situations. -Surveys, education, and extension topics related to weeds will also be considered
